Full textAbstract:
Recent years have seen a small but consistent growth in the use of AI on commercial pig farms in Britain. Currently about 12 percent of all matings are artificial and 25 percent or more of farms are using some AI.(6) This figure still falls well short of our continental neighbours, with Denmark and the Netherlands inseminating 50 percent of their sows. The conception rate and litter size achievable with AI (6) can at least equal results from natural matings. However, it is recognised that some people achieve far superior fertility results to others when using AI. Part of this is due to different genotypes employed (e.g. purebreds vs crossbreds), different production systems and management practices imposed. It is most likely, however, that an unquantified but substantial part of the reason for such big differences between farms in fertility following AI is due to differing abilities of stockpeople performing the inseminations. “Ability’ refers not only to the actual insemination technique, which is straightforward and can be quickly learned, but to their general ability to recognise behavioural changes in their stock, to interact with their stock and generally get the best out of their stock i.e. their level of stockmanship skills.

The aims of this research are to know: level of productivity and income of cow farmers by artificial insemination, and natural farmer; in Tasikmalaya. Survey was the method used. There were 15 farmer as sampling unit of The Insemination Farmer and 17 the natural farmer. The result of the research can be concluded that: The produkductivity of artificial insemination farmer more than the productivity of natural farmer; both of the farmers were on equal fragnant productivity. It were one baby cow for one time of the fragnan. But the artificial insemination farmer have short interval. On 23 Th months the artificial insemination farmers have two times fragnant; the growth rate of the artificial insemination cow was faster then the growth rate of the natural cow. The baby cow by artificial insemination reach 105-110 kg on 4 Th months, but the natural were only 65-75 kg on 6-8 Th months. Net income of artificial insemination farmers were 5,65 percents on the total investments, while the natural farmer were 3,44 percent per month.

Seventy-nine men with Hodgkin's disease were treated with chemotherapy protocols at Memorial Sloan-Kettering Cancer Center and had pretreatment semen analysis performed at the area semen bank. The patients were evaluated to determine: the quality of pretreatment semen, the effect of treatment on spermatogenesis, and the success rate of artificial insemination after semen cryopreservation. Pretreatment sperm concentration, fresh motility, fresh progression, postthaw motility and postthaw progression were all significantly decreased in men with Hodgkin's disease compared with normal controls. Posttreatment semen analysis in 44 men showed azoospermia in 80%, sperm concentration, less than or equal to 10 X 10(6)/mL in 11%, and sperm concentration greater than 10 X 10(6)/mL in 9%. Eleven couples attempted artificial insemination using cryopreserved semen, thus far resulting in three pregnancies. Semen cryopreservation and artificial insemination offer a partial solution to posttreatment azoospermia in this population, but further methods are needed to minimize gonadal toxicity without compromising therapy for Hodgkin's disease.

ABSTRACT Ongole cross bread has important role in the economical needs of people in Tompaso Barat. In addition as beef cattle, household farmers also use it as a working cattle, source of fertilize and investment. In addition to farmer’s income and the acceleration growth of cattle population, in the year of 2011, District West Tompaso Barat did an artificial insemination program. The problem was whether this program is beneficial for the farmer or not. The aim at this research is to analyze the profit of farmers using artificial insemination program. This research was conducted using survey method involving about 169 farmers raising Ongole crossbred cattle at West Tompaso District applying artificial insemination. The data were analyzed by profit analysis. Result showed that the total income received from the total sale of the beef cattle using artificial insemination were IDR 490,950,000.- with the total cost of IDR 468,945,750. The profit of the household farmers was the balance between the total income and the total cost getting IDR 21,504,250. The average income of the respondent was about IDR 716,808. Therefore, it can be concluded that the household farmers raising Ongole crossbred cattle get more profit when they used artificial insemination. Based on this research it can be suggested that the beef cattle management should be maintained on the bases of agribusiness. Keywords: Profit, Ongole crossbred cattle, Artificial Insemination

Full textAbstract:
The scientific method of artificial insemination is one of the reproductive technology that came into widespread use some decades ago. With this method, some couples with fertility problems can now have children through artificial insemination; a process where concentrated male semen is introduced into the female reproductive system artificially in the clinic for childbearing. The increasing cases of childlessness, infertility or barrenness among married couples and request from the homosexuals (gay and lesbians) have given rise to high demand for artificial insemination. Today, there are commercial sperm banks that store frozen sperms for sell to those who need them. This artificial method of childbearing has generated serious controversy among theologians, bioethical and Christian scholars. Artificial insemination has indeed given hope to many couples globally whose marriages were threatened due to the problem of barrenness, childlessness or reproductive malfunctioning. The major Christian and ethical concern is that the process is artificial and manipulative rather than being natural. This paper aims to examine the biblical perspective of this phenomenal scientific breakthrough and show whether or not artificial insemination is compatible with the Christian doctrine of marriage and childbearing. The research method adopted is descriptive, using secondary materials from journals, textbooks and websites to elucidate the points. The study reveals that there is no consensuses agreement on the issue of reproductive technology among Christian scholars and the biblical interpretation of some related passages are not explicit on issues of reproductive technology. The study, therefore, recommends a more natural way of treating the issues of infertility, barrenness and childlessness by investigating into the causes of infertility and proffer a curative solution rather than resort into masturbation and commercialization of human sperm and egg.

Full textAbstract:
The purpose of this review was to analyze factors affecting the popularity of artificial insemination of mares in Europe in the context of sperm quality. Taking into account the prices of stallion semen on the world market, efficiency is important for the profitability of its use in artificial insemination programs in Europe. To increase the efficiency of a semen insemination facility, it is necessary to correctly and objectively assess the quality of semen. The available range of tools allows an effective evaluation of the potential fertility of a stallion. For several years, artificial insemination programs in Europe have been gaining popularity. However, the frequency of chilled or frozen semen use is still quite low. This is mainly due to the common, negative opinion about the effectiveness of the use of packaged insemination doses as opposed to natural insemination. Unfortunately, the quality of the semen offered often deviates from expectations, which results in unsatisfactory (and therefore unprofitable) pregnancy rates. This review presents the popularity structure of chilled and frozen semen use in European horse breeding as well as the current state of research on the effectiveness of semen production technology. It is shown that the popularity of using chilled semen in the artificial insemination of mares in Europe has been gradually increasing in the group of sport mares, while in the group of breeding mares, in recent years, frozen semen has been gaining popularity. In the remaining group of mares (not classified as sport or breeding), insemination with chilled semen has been dominant.

A research group of Animal Science Faculty of Brawijaya University introduced and implemented Frozen sexed semen Artificial Insemination to 120 beef cattle farmers in Palang Village, Tuban Regency, East Java, from 2017 to 2019. The result of the program reported that the success rate of the technology is quite high, with the birth rate of male claves up to 80%. However, farmers’ adoption rate of the technology was relatively low. This research aims to evaluate factors that affected the adoption rate including the technology, characteristics of respondents, and the extension agents. Primary data were collected through a census of 120 farmers involved in the program and in-depth interviews with stakeholders. Secondary data were collected through related documents including reports of the programs, Statistics, and other related documents. This research utilized Quantitative and qualitative analyses. Data of the study indicated that respondents have neutral perceptions of the Frozen Semen Sexing Artificial Insemination. Although male calves relatively have a higher price, more than 50% of respondents did not expect specific sexing for the calves. In-depth interview data revealed that the success of the Artificial insemination technology is more valuable for the farmers rather than the sexing. Characteristics of respondents and the extension agents played significant roles in the adoption rate of the Frozen Sexed Semen Artificial Insemination technology adoption in Palang Village, Tuban Regency, East Java.

The aim of this study was to facilitate artificial insemination training to enhance sustainable pig production within the developing smallholder pig production sector in Gauteng Province, South Africa. Eighteen smallholder pig farmers with requisite structures (pig house, pens), pigs (large white, landrace duroc or South African indigenous) and management (feeding, cleaning and record keeping) capacity were trained on routine pig management and artificial insemination procedures in a “learning by doing” on-farm supervised programme administered by Agricultural Research Council, Animal Production pig training team. Following estrus detection, 96 sows were artificially inseminated and 31 naturally served (NS). Farrowing rates (FR), total born (TB) and born alive (BA) piglets were recorded. The occurrence ccurrence of mummified fetuses (0.019 vs. 0.022%) and weak piglets (0.038 vs. 0.049%) did not differ between artificially inseminated sows and naturally mated sows. Born alive, birth weight and weaning weight were higher for artificial inseminated sows. The average litter size was 15± and 13±, birth weight 1.98±0.79 kg and 1.48±0.58 kg and weaning weight 9.89±0.87 kg and 7.23±0.71 kg for the AI and NS litters, respectively. Farmer demographic factors (age, gender and educational level) had no effect on farrowing rate, total born and piglets born alive. Therefore, implementation of artificial insemination techniques and pig production training was feasible under a smallholder pig production system.

This research was conducted to find out the Body Condition Score (BCS, in nine scale) of 30 Limousine crossbred cows in Balongpanggang, Gresik regency at the time of Artificial Insemination, 21 and 60 days later. Questionnaires obtained to identify the knowledge of farmers and inseminators in estrous detection. Conception Rate (CR) and Service per Conception (S/C) counted based on pregnancy diagnosis through rectal palpation 60 days post insemination. The result showed that the average of BCS in pregnant cows at 60 days post insemination was highest compared to the others. Conception rate and service per conception of the cows were 60% and 1.63 respectively, meanwhile the knowledge of estrous detection of farmers was lower compared to those of inseminator. It could be concluded that implementation of AI technique in Limousine crossbred cows at Balongpanggang, Gresik regency was good enough, but the knowledge of farmers about estrous detection needs to be improved.

Small Ruminant such goats are familiar to keep growing for a farming system in the rural area. However, farmers are facing many problems to grow them. This study describes the goat farming system's performance in the rural area based on the farmers’ attitude and factors influencing farmers in adopting Artificial Insemination of the goat farming system. This study was conducted in Wunduwatu Village Andoolo Sub District, South Konawe District of Southeast Sulawesi Province in 2015. The research method was employed based on the survey and interview using a questionnaire through a purposive sampling method for selecting respondents that have chosen 30 farmers. Research findings show that its farming system's performance indicated the traditional pattern such as feed performance and farm management. It is due to the lack of skill and lack of capital. Most of the respondent farmers (44.29%) perceived artificial insemination is a good program. Moreover, 60.50% of respondents stated that using artificial insemination is better than using a male / natural mating.

Full textAbstract:
Many years of research have been devoted to improving the fertility of preserved semen of small ruminants. There have been few significant advances in preservation in recent times, but considerable knowledge has been gained on the effect of preservation on the structure and function of spermatozoa. It has become evident that preservation greatly affects many sperm attributes, such as motility, respiratory activity, membrane status and DNA quality. Consequently, viability is reduced, transport in the female reproductive tract is inhibited, the timing of fertilisation is altered and embryo development is affected following insemination of preserved, compared to fresh spermatozoa. A greater understanding of their functional condition may lead to the development of methods of preventing these alterations or to improved methods of using the preserved spermatozoa for artificial insemination in their altered state.

Full textAbstract:
The latest entry in the field of semen evaluation is computer assisted semen analysis (CASA). Heterospermic insemination has been used to increase pregnancy rates from low fertile bulls. The objective of this study was to evaluate, with the aid of CASA, heterospermic semen characteristics and pregnancy rates using different concentrations of bull semen in a timed artificial insemination protocol. Semen was collected from two bulls of known fertility by artificial vagina and all CASA motility parameters were evaluated individually and combined. Straws were filled using a semi-defined semen extender (Andromed, Minitüb, Tiefenbach, Germany) as follows: single bull A and single bull B (12 × 106 of progressive motile cells after thawing); Mixed bull semen: A + B (12 × 106 of progressive motile cells after thawing) and Supermix bull semen: A + B (28 × 106 of progressive motile cells after thawing). All cows received a P4 intravaginal device (DIB, Syntex, Argentina) and 2 mg of EB i.m. (Syntex) on Day 0, 500 mg cloprostenol (Estroplan, Syntex) at the time of DIB removal (Day 8), and 1 mg EB i.m. on Day 9. Fixed-time insemination (FTAI) was performed at 52 to 56 h after DIB removal. A total of 249 cows were randomly allocated to be inseminated with bulls A and B (n = 76), with Mixed A + B (n = 87), and with Supermixed A+B at a high concentration (n = 86) by a single inseminator. Pregnancy rates were evaluated at 38 days after insemination by transrectal ultrasonography. Means and standard deviations or each characteristic were calculated, compared, and statistically analyzed. The following sperm motility parameters were determined with the Ceros 12.1 sperm analyzer (Hamilton Thorne Biosciences, Inc., Beverly, MA, USA) on at least 1000 spermatozoa: velocity average path (VAP), velocity straight line (VSL), curvilinear velocity (VCL), amplitude lateral head (ALH), beat cross frequency (BCF), straightness (STR), linearity (LIN), and percentage of rapid or static cells. There were no significant differences (P > 0.05) in VAP, VSL, VCL, ALH, STR, or LIN. There was a numerically higher percentage of rapid cells in the Supermix semen. Pregnancy rate from bulls A and B was 61% and from Mixed A + B 60%, while that from Supermixed A + B was 69%. Results from the analysis indicate that semen concentration is an important element to be considered in a timed artificial insemination program. Numerically higher pregnancy rates were obtained with double semen concentration in the straw. More research is required to evaluate the interaction between different breeds within a timed artificial insemination program. This research was supported by Centro Genético Bovino de EOLIA sa and Syntex sa Argentina.

In the article it is highlighted the results of research on the features of cervix permeability and optimal periods of fertilization in pubertal gilts. Five high-productive boars of the Large White breed, aged 18-36 months, were used in experiments and evaluated for the quality of sperm. The start of the estrus was carried out using a test boar. In the first experiment to determine the permeability of the cervical canal, 3 groups of the Large White breed were formed for 15 heads in each, which were inseminated at the onset: of the first (1st group), the second (2nd group) and the third period of the estrus at the age of 6 - 8 months. Gilt were fertilized with a sperm dosage of 70 ml of a diluent containing 2 billion of spermatozoa. In the second experiment to determine the optimal timing of insemination, 66 gilt of the Large White breed aged 8 to 9 months, live weight 110-130 kg, with clear signs of the start of proestrus, estrus and diestrus were used. The beginning of the estrus was set twice a day at 7 o'clock and 19 o'clock. The doses of sperm (2 billion of spermatozoa in 70 ml of diluent) were injected into the gilts according to the following scheme: Group I - after the prescribed period of the estrus - 0 hours; Group II - after 6 hours; III - group - 12 hours; Group IV - 18 hours; V - 24 hours; VI - 36 hours. It has been determined that cervical permeability increases with age of gilts and the number of reproductive cycles. In gilts, in the first reproductive cycle, the permeability of the cervical canal is 4.61 cm and intensively increases twice: 1.9 (p <0.001) (2nd estrus) and 2.5 times (p <0.001) (3rd estrus). The introduction of sperm by the intracerviсal method on the third period of the estrus allows them to be fertilized at a level of 86 % and receive 10.2 newborn piglets.Cervix permeability in gilts increases from the beginning of the estrus for the next 24 hours. The high indexes of their reproductive capacity are determined at the introduction of sperm dosage in 24-36 hours after the onset of the estrus. The number of live newborns piglets was maximal when sperm is introduced into cervix of gilts in 12; 24 and 30 hours after the start of the estrus. The live weight of newborn piglets depends on the period of the introduction of sperm into the pigs, being maximal at the start of the estrus, and in 24 and 30 hours after the introduction of sperm. The postponement of the procedure up to 36 hours leads to a decrease of this index (p <0.001). Key words: reproductive cycle, estrus, cervix, fertilization, sperm, gilt.

The government launched the Beef Self-Sufficiency Program in 2014 to support the National Food Security and Diversification Program. One of the steps taken is the optimization of Artificial Insemination (IB) and Natural Marriage Intensification (INKA). In 2017, a new plan was issued, a special effort (Upsus) for “SapiIndukanWajib Bunting”(SIWAB) with the aim of increasing beef cattle population and leading to beef self-sufficiency. This study aims to assess the extent of the implementation of strategies by inseminators and breeders in achieving IB targets and to determine new strategies in optimizing the achievement of IB results. This research was conducted within the SinjaiAnimal Husbandry and Animal Health Service office. Data were collected through interviews and questionnaires then analyzed using a qualitative descriptive method, IFAS (Internal Factors Analysis Summary) and EFAS (External Factors Analysis Summary), SWOT (Strengths, Weaknesses, Opportunities, Threats) and TOWS analyzes to design development strategies. As a result, SIWAB with the Artificial Insemination Program is still below the target. Evaluation of the strategy using SWOT and TOWS analysis in the artificial insemination program shows that internal forces still need to be supported by the use of external forces, in this case, government policy. Strategy formulation after the application of the TOWS matrix shows alternative strategies that can be taken to optimize the achievement of artificial insemination results.

The aim of the research was to determine the dependence of physical properties of boar ejaculates on the time interval between successive ejaculate collections. The material for the study comprised 1954 ejaculates collected manually from boars used for artificial insemination. For all ejaculates, the ejaculate volume, sperm concentration, percentage of motile spermatozoa, and number of spermatozoa in the ejaculate were determined, and the number of insemination doses per ejaculate was calculated. The boars’ suitability for artificial insemination was evaluated taking into account the effect of the time passed between ejaculate collections. The ejaculate volume and the concentration and number of sperm in the ejaculate were shown to increase with the time elapsed since the previous ejaculate. The number of insemination doses obtained per ejaculate increased as well. Ejaculates with a high sperm count were obtained when the ejaculation frequency was no more than every 4 days. The percentage of spermatozoa with progressive motility increased with the time elapsed since the collection of the previous ejaculate, but only up to 4 days. Further decreases in ejaculation frequency no longer resulted in increased sperm motility.

Full textAbstract:
In addition to assessing the absolute performance of animals, the impact of certain technological approaches, breeding influence and other external organized factors on the consolidation of pigs groups on certain grounds should be evaluated. Breeding consolidation is a desirable breeding process that is realized through more motivated consolidation of intra-breeding structural units for maintaining a significant level of intergroup differentiation and variability. If the issue relates to the rearing young animals that are introduced into the herd, this is the most urgent issue that needs to be monitored. The purpose of the research is to determine the consociality of the main signs of reproductive ability of the gilts, which are checked at different rates of artificial insemination of sows of the main herd. The research was carried out at the Shubs`ke farm in the Bogoduhivsky District of Kharkiv Oblast at the pig farm for the pure breeding of the Welsh breed pigs (breeding reproductive status from 2014). In order to evaluate the optimal multiplicity (from single to triple), a gilts with a total of 30 heads was selected. The main indicators of reproductive ability of gilts (multiplicity, weight of nest at birth and excommunication and keeping piglets before weaning on day 28) were evaluated. Recalculation on the weight of the litter at weaning at the weight of the nest at extermination in 60 days was carried out in accordance with the current instruction on the boning of pigs. The results of researches were worked out according to traditional methods by the method of variation statistics. Consolidation of individual indicators of reproductive capacity of gilts was calculated to the total number of evaluated animals. In the previous stage of the research, it was found that the use of multiple insemination of gilts compared to single insemination is positively reflected at the level of their reproductive ability. A decrease in the percentage of non-productive inseminants in animal groups has been established. Triple insemination of gilts allows for 1.14 piglets to be obtained more compared to single insemination of the same pigs (p < 0.01). Also, for three times insemination of gilts, in comparison with single insemination, larger nest for weaning were obtained (by 14.24 kg, converted to 60th day p < 0.01). At the same time, the reduction in the keeping of piglets to weaning for increase frequency of insemination of gilts. According to the multiplicity of gilts, the most consolidated level of symptoms per group was obtained for single insemination. Increasing the multiplicity of insemination negatively affected the consolidation of the multiplicity of the piglets (as for determining the coefficients of phenotypic consolidation due to the mean square deviation, so, and for determining the coefficient of variability). The least consolidated in terms of multiplicity were uterus for double insemination. It should also be noted that there is little difference, in general, on the indicators of the theonotypical consolidation of the multiplicity of piglets between different groups of animals. So this difference between the most contrasting groups was 0.447 points for determining the coefficients due to the mean square deviation and 0.397 points for the determination due to the coefficient of variability, respectively. By weight of the same litters at birth, the most consolidated group was gilts, which was inseminated twice. The least consolidated are trimmed three times, respectively. The difference as a whole, according to the indicators of the theonotype consolidation of the mass of the litter’s piglets at birth, between different groups of pigs was even smaller. The difference between the most contrasting groups was 0.270 points for determining the coefficients due to the mean square deviation and 0.260 points for the determination due to the coefficient of variability, respectively. On the basis of the mass of the litter at weaning, the most consolidated level of symptoms was obtained in the group of gilts for triple insemination. The least consolidated group, respectively, was gilts for single insemination. At the same time, on the basis of the weight of the litter at weaning, the slightest differences were obtained after the consolidation of the signs between different groups of pigs. The difference between the most contrasting groups was 0.173 points for determining the coefficients due to the mean square deviation and 0.248 points for the determination due to the coefficient of variation, respectively. At different rates of insemination of gilts, there are no significant differences between the groups between the groups in terms of the consolidation of signs of reproductive ability. Also, there was no clear effect on increasing the multiplicity of insemination of gilts to the consolidation of their signs of reproductive qualities.

Sampling technique used Slovin formula with 90% significant rate to observe variables, namely the ability of farmers to adopt AI technology (Y); social factors (X1) consisting of age (X1.1), educational background (X1.2), farming experience (X1.3), herd size (X1.4); technical factors consisting of S/C (X2.1) and oestrous detection (X2.2); and economic factor is AI costs (X3). The research data obtained were analysed using descriptive analysis and correlation. The results showed that adoption of artificial insemination in beef cattle in Brebes Regency had a negative correlation with age (X1.1) (rs = -0.498), did not correlate with educational background (X1.2) (rs = 0.221), farming experience ( rs = X1.3) (rs = -0.056), and the herd size (X1.4) (rs = 0.094) as social factors; does not correlate with the value of S/C (X2.1) (rs = 0.203) and estrous detection (X2.2) (rs = 0.259) as technical factors; and negatively correlate.ed with AI cost (X3) (rs = -0,661) as an economic factor. From the results of the study, it can be concluded that the adoption of artificial insemination in beef cattle in Brebes Regency is influenced by social and economic factors, especially from the age factor and AI cost factor that is less supportive.

Full textAbstract:
Abalone is one of the marine mollusk that has high economic value. Mass abalone cultivation requires the mature gonads broodstock to produce seeds, but the maturity of the gonads of male and female often can not be simultaneously. Artificial insemination using a solution of ammonia is one solution to produce abalone seed in the hatchery. Ammonia solution can increase motility, fertilization rate of eggs and abalone seed production, so the provision of seeds for cultivation of abalone is independent from nature. The research of artificial insemination was carried out at various levels of gonadal maturation dams abalone (H. asinina) to determine the percentage of fertility and hatching rate of eggs from each Gonad Maturity Level. In stadia gonadal recovery, no fertilization occurs, whereas in the gonads maturing stadia had fertilization and hatching rate 24.33 ± 2.08% and 22.12 ± 2.18%, respectively at ripe stadia, gonads had been fertilization and hatching rate were 94.67% ± 1.53% and 82.82% ± 3.58%, wasn’t recorded in the stadia spent fertilization did not occur because the eggs were released in culture media. Gonad Maturity Level, thus can be used in artificial insemination was the ripe gonadal stadia, which had the highest percentage of both levels of fertilization and hatching rate with a diameter ranging from 189.6-252.8 μm. Key Words : Abalone (H. asinine); Artificial breeding; Gonad Maturity Level; Hatching Rate

Full textAbstract:
The complex anatomical structure of the ewe reproductive tract accompanied with low quality of frozen ram semen for artificial insemination, resulted in a challenge with regard to using superior genotypes for reproductive ovine performance. Hence, improved genetics in ovine management has not been efficiently and widely used especially in undeveloped countries. Therefore, intrauterine semen deposition by laparoscopic insemination should be adopted in the current sheep production systems. Thus, this study aimed to assess the pregnancy rate and lambing rate of ewe inseminated by laparoscopic insemination techniques using frozen-thawed semen. The research used imported frozen semen from two rams of the Lacaune breed. Ewes were grouped according to age in years (1, 2 and 4). Before insemination, the semen was examined microscopically for its motility and viability and thereafter the laparoscopic artificial insemination technique was performed to 19 Lacaune breed ewes using frozen-thawed semen. The overall pregnancy and prolificacy rates were 31.57% and 42.10% respectively. Out of 2 ewes in the 1-year age group that were inseminated, only 1 ewe lambed representing 50%. However, from 16 ewes inseminated of four-year age group, 5 ewes lambed representing 31.25%. Significant difference based on age group was not evaluated due disproportionate of the data, (such that the data included 2 ewes in one-year-old age, 1 ewe in 2-year-old age and 16 ewes in 4-year-old age). Based on the ram semen, 33.33% and 30% of the inseminated ewes were pregnant from ram A and ram B semen respectively. However, in the case of prolificacy rate, 44.44% and 40 % of the ewes lambed from using semen of ram A and B, respectively. There was no significant difference (p>0.05) in pregnancy and prolificacy rates based on semen from the two rams. In conclusion, in this research study, ram semen had no significant effect on pregnancy and prolificacy rates using laparoscopic AI on Lacaune sheep. This could be due to the fact that the rams had very good quality semen. Evaluation of ram semen, accompanied with appropriate ewe selection based on age and rightful deposition of semen could lead to better and more consistent results. Overall this could contribute to the successful application of laparoscopic artificial insemination in Lacaune sheep production systems for enhanced productivity.

Full textAbstract:
Ram semen cryopreservation contributes to genetic improvement through artificial insemination, eliminates geographical barriers in artificial insemination application and supports the preservation of endangered breeds thus the conservation of biodiversity. Sperm freezing process induces ultrastructural, biochemical and functional changes of spermatozoa. Especially, spermatozoa’s membranes and chromatin can be damaged, sperm membranes’ permeability is increased, hyper oxidation and formation of reactive oxygen species takes place, affecting fertilizing ability and subsequent early embryonic development. Aiming to improve ram frozen-thawed semen’s fertilizing capacity, many scientific investigations took place. Among them the composition of semen extenders, was a main point of interest. Semen preservation extenders regulate and support an environment of adequate pH and buffering capacity to protect spermatozoa from osmotic and cryogenic stress. Therefore, permeating (glycerol, dimethyl sulfoxide) and non-permeat ing (egg yolk, skimmed milk) cryoprotectants, sugars (glucose, lactose, trehalose, raffinose), salts (sodium citrate, citric acid) and antioxidants (amino acids, vitamins, enzymes) have been added and tested. Moreover, semen dilution rate, storage temperature, cooling rate and thawing protocol, are also some key factors that have been studied. The research results of this scientific topic are encouraging, not only about the freezing and thawing procedures, but also about the improvement of the additives’ properties. However, further research is needed to enhance the fertilizing ability of ram frozen-thawed semen, making its use practical in sheep reproductive management by the application of cervical artificial insemination.

Beef Cattle is one of the meat-producing resources that have great benefits for the fulfilment and improvement of community nutrition. The low population of Beef Cows is because most of the livestock are kept on a small scale with limited land and capital. In addition, the weather does not threaten animal health. To carry out preventive activities against outbreaks of disease in livestock, the government program CallNak Center. The research objective was to analyze the effect of animal health services, health status checks, and artificial insemination on the development of Beef Cattle. The research method used quantitative research with a cross-sectional study approach. The research was conducted in Parepare City from August 2020 to April 2021. The sampling technique used non-probability sampling with purposive sampling with a total sample of 73 breeders. The data analysis used in this study is the Chi-Square Test. The results showed that the majority of respondents (76,71%) felt the benefits of animal health services, and health status checks and respondents considered beneficial were 78,08%. Meanwhile, respondents who felt the benefits of Artificial Insemination (IB) services were 50,68% or only a difference of 1,36% were considered less useful. Respondents who stated that they had experienced the development of beef cattle since the CallNak Center was 82,19%, while only 17,81% had ever developed. The results of the analysis show that animal health services and health status checks and those which significantly affect Artificial Insemination do not significantly affect the development of cattle in Parepare City.

Full textAbstract:
In this paper, the author analyzes family status of the child conceived by artificial reproduction technologies using the following treatments: homologues artificial insemination, heterologus artificial insemination (artificial insemination by donor), ovum donation, embryo donation and surrogate motherhood. One specific situation of homologues artificial insemination is posthumous insemination, insemination after the death of the husband/partner. This procedure is allowed in, for instance, United Kingdom, but not allowed in France, Switzerland, and Italy. Considering genetics elements in this situation there is no doubt on fatherhood - father is a man whose sperm is used for insemination, regardless of the fact if frozen sperm or frozen embryo is used in the procedure. Nevertheless, until 2008 in United Kingdom, the husband/partner was not considered as legal father, because of the fact that the child was born after his death. Heterologous artificial insemination could be used in three different situations. First, when subjects are spouses or unmarried partners of different sexes. Second, when subjects are spouses or unmarried partners of the same sex and the third if a single woman is an only subject. Most recent procedure is the one in which subjects are spouses or unmarried partners of the same sex, specifically two women. This procedure is allowed in the United Kingdom and Sweden. In these legislatures, there is a rule that the woman who delivers the child is legal mother, and her spouse/partner is a second parent of the child. The most recent procedure of egg donation is a donation of only a part of an egg, mitochondrial DNA. In this case, there are in fact three genetic parents of the child: two genetic mothers and a father. Legally, the child has one mother (the woman who delivers a child) and a father. One of potential outcomes of the recent research is the ability to create human embryo without any male genetic contribution - by transferring the nucleus of a somatic cell from one woman into an enucleated egg of another. In that case, the child would not have genetic father at all. Bearing in mind the new artificial reproduction technologies and their influence to legal rules of establishment of the family status of the child, it could be said that the legal principle of the autonomy of the parties is widened in comparison to material truth. People who wish to be parents become legal parents although they are not generic parents. Sometimes they cannot be genetic parents due to their infertility and sometimes because they are of the same sex. As a result of artificial reproduction technologies, a child could have a genetic link with one of the parents, only with a mother - in the heterologous insemination, only a father - as in egg donation and genetic surrogacy. The child could have genetic link with both of the parents - as in the gestational surrogacy, or it could have no genetic links with his/her legal parents - as in embryo donation. According to some European legislatures, it is possible for the child to have a mother and the other female parent, or a father and the other male parent. Surrogate mother, as well as donors of the genetic material, are not considered as parents. Radical change in social and individual perception of parenthood could accept the fact the child could have more than two parents with different roles (biological - genetic parents, gestational mother, social - legal parents).

The quality of liquid semen with coconut water as diluent could be preserved up to 3 to 4 days during cold storage at 4 - 5oC. In this research, the successful insemination rate of coconut water-based diluent Boer goat liquid semen was observed to understand the application of coconut water as semen diluent. The materials used in this research were 5 to 7 months Viridis coconut water, liquid semen from 3 years old Boer buck, 30 does for acceptor, and Tris-aminomethane added with 10% egg yolk (EY) as a control diluent. The Boer semen was collected once a week by using artificial vagina, diluted and then stored before used for insemination. The insemination was done by using intra-cervical method at position 3, started with estrous synchronization by using 2 mL PGF2α. The research was conducted as experimental method under randomized group design with two treatments, that were Tris-aminomethane + 10% EY (P0) and coconut water + 10% EY (P1). All of the treatments were repeated for 15 times and the collected data were analyzed with Pearson’s chi square with Genstat 18 program. The observed variables include non-return rate and kidding rate. The results showed that the first non-return rate of P1 were 93.33% and in P0 were 73.33%, while the second non-return rate of P1 were 93.33% and in P0 were 80%. Furthermore, the kidding rate of P1 were 40% and P0 were 66.66%. The Pearson’s chi square analysis showed that there was no effect of coconut water as semen diluent to the kidding rate. The research concludes that the usage of coconut water as semen diluent did not affect the successful insemination rate of Boer goat.

In all domestic species, acceptable pregnancy rate with frozen-thawed semen is 20-30% through simply cervical and vaginal insemination. Researchers have proved that achievable high results can be expected only from intrauterine insemination in ewes. Unlike the cow, and goat, the cervix of ewes is a formidable barrier to penetrate for transcervical intrauterine insemination. It is not only due to the physical size of the canal and a narrow luminal diameter (even at estrus), but also due to its caudally facing eccentric series of four to eight funnel-like rings. The major aim of this study was to evaluate a comparison of transcervical and laparoscopic intrauterine artificial insemination techniques with frozen –thawed semen on the reproductive performance of ewes.58ewes of 3-4 years of age, so called Altanbulag subspecies of breed were selected and equally divided into 2 groups for the AI methods from October 15-20, 2013 in the breeding station of Research Institute of Animal Husbandry in Hongor sum, Darhan uul province. The estrus was synchronized with EAZI-BREED TMCIDR in which the progesterone content was 0.3 g. After 12 days, the CIDR were removed, PMSG of 400 and 200 IU were administrated intramuscularly per ewe. The total success of synchronization rate was 93.3%. The results has shown the possibilities of laparoscopic and transcervical AI techniques in 55.17%, 41.37% (p>0.05) of pregnancy rates respectively, with frozen-thawed semen in ewes by ultrasonography diagnosis.Mongolian Journal of Agricultural Sciences Vol.13(2) 2014: 43-47

Flow sorting cytometry has been shown to repeatedly produce viable sexed sperm at a level necessary for commercialization. Previous reports have shown that pregnancies rates were lower using sexed semen than commercial nonsexed semen. Sperm concentration, acrosome activation, and time to ovulation are some factors explaining the low conception. The objective of the present study was to compare pregnancy rates using sexed semen (3 × 106 sperm) deposited in different locations of the bovine uterus (body v. horn) and inseminated (AI) at 2 different times (52 h v. 58 h after progesterone intravaginal device removal). Holstein heifers, between 15 to 18 mo of age and a body condition score 3.05 ± 0.22 were used. All heifers were evaluated by transrectal ultrasonography to determine ovarian structures (284/357, 79.5% had a CL). On Day 0, all heifers received an intravaginal progesterone (P4) device (1.9 g of P4, CIDR, Pfizer, Buenos Aires, Argentina) plus 70 μg of D-cloprostenol (Bioprost, Biotay, Argentina) i.m. and 2 mg of estradiol benzoate (EB, Syntex SA, Buenos Aires, Argentina). On Day 8, CIDR devices were removed and heifers received 150 μg of D-cloprostenol i.m. at the same time. On Day 9, all heifers received 1 mg of EB i.m. and were randomly allocated in 4 different groups (2 × 2 factorial): group Body-52 h, AI in the body of the uterus at 52 h (n = 98); group Body-58 h: AI in the body of the uterus at 58 h (n = 104); group Horn-52 h: AI in the ipsilateral horn of the ovulatory follicle (detected by ultrasonography) at 52 h (n = 90) and group Horn-58 h: AI in the ipsilateral horn to the ovulatory follicle at 58 h (n = 65). All heifers were inseminated with only one dose of sexed semen. At time of AI an ultrasound examination was done to determine the size and the location of the preovulatory follicle. AI was done by a single inseminator using a traditional AI gun, and an embryo transfer gun (ET sheath, SBS Cryotec SA, Argentina) was used for deep AI. Pregnancy diagnosis was evaluated by transrectal ultrasonography using a 7.5-MHz transducer (Mindray 6600) 30 days after AI. Data were analyzed by logistic regression. Sixty percent of the preovulatory follicles were on the right ovary, and there were no differences between the sizes of the preovulatory follicle among groups (overall mean ± SEM: 15.5 ± 1.0 mm). Although pregnancy rates did not differ between horn (64/155, 41.2%) and body (70/202, 34.3%; P < 0.1) inseminations and between 52 h (67/188, 36.7% and 58 h (67/169, 39.6%), pregnancy rates were higher (P < 0.05) in heifers inseminated in the horn at 58 h (32/65, 49.2%) than those inseminated in the body at 58 h (35/104, 33.6%) and tended (P < 0.09) to be higher than heifers inseminated in the horn at 52 h (32/90, 35.5%) and in the body at 52 h (35/98, 35.7%). Fixed-time artificial insemination using ultrasonography and deep insemination could contribute to enhanced pregnancy rates using sexed semen in Holstein heifers. This research was done with the support of ADECO SA, SBS Cryo Tec SA.

The scientific researches of the scientist Anatoly Andreevich Belikov, doсtor of Agrarian Sciences, in the field of pig reproduction were analysed. The scientist has played the essential role in the theoretical substantiation and technological equipment of the methods in scientific researches, related to the study of the fertilizing ability and artificial insemination in pigs using cryopreserved sperm. The most significant achievements in the development of long-term storage method of boar sperm in the deep-frozen state, its evaluation, thawing and insemination of sows are highlighted. The issue of semen deep freezing of farm animals in the middle of the twentieth century was relevant, because it allowed to preserve the genetic material (semen) of valuable breeds and species of animals. Profitable pork production would be impossible without advances in reproduction and artificial insemination. Scientific research on the development of a method for deep-freezing boar sperm in liquid nitrogen, was started in 1972 by A. A. Belikov, was aimed at testing different modes of sperm cooling - ultra-fast (vitrification), fast, moderate and slow. The best results were obtained with a fast mode of freezing and thawing of sperm. Scientists have conducted studies to see the possibility of replacing glycerin in cryopreservation media with other cryoprotectants. For the first time, in 1984, fertility was achieved by artificial insemination of pigs with frozen-thawed sperm with the addition of ethylene glycol instead of glycerin, at the level of 45-83 % with a fertility of 7-9 piglets per farrowing. Later in 1992, A. A. Belikov's research was aimed at studying certain theoretical issues concerning the freezing and thawing of diluted whole sperm and its thick fraction. The method of this experiment involved separating a thick fraction of ejaculate in the process of ejaculation in a boar under visual inspection. The result of the research and production experiment was the insemination of sows, whose fertility was on average from 46 to 76 %, with the release of piglets from 6 to 14 heads per farrowing. Created in 1990 by scientists together with the staff of the All-Russian Institute of Animal Husbandry, a bank of boar semen frozen in pellets, made it possible to use it both in Ukraine and abroad.
