Ovarian hypofunction in cattle is reproduction disorder related to massive economic loss. Etiology of this ovarium disfunction are low quality feed, minimum health concern, poor sanitation and pen problem. Eighty-five (85) Peranakan Ongole (PO), Peranakan Limosin (PL) and Peranakan Simental (PS) cows from Prambanan Sub District of Daerah Istimewa Yogyakarta were diagnosed with ovarian hypofunction by rectal palpation and physical examination. The cows were then programmed for ovary condition recovery by administration of vitamine A,D,E (IM), per oral anthelminthic bolus (Klosantel) and premix mixture in feed given daily for 4 weeks. After 4 weeks, the cows were re-examined. Sixty-two (72,9%) cows were recovered from ovary hypofunction, however ovaries of 23 (21,9%) cows were palpated abnormal, which require another administration of A,D,E (IM). There were no significant difference between the type of cows (PO,PL,PS) with recovery percentages after one programme therapy (P>0.05). It can be concluded that single injection of vitamin A,D, E , per oral bolus of Klosantel, and addition of premix into feed daily for 4 weeks were able to reduce 72,9% ovary hypofunction in Peranakan Ongole, Peranakan Limosin and Peranakan Simental cows at Prambanan sub district, Daerah Istimewa Yogyakarta.

SummaryFor over 2.5 million dairy cows subject to assessment in Poland in 2005–2010, gestation length was analyzed. This trait follows a normal distribution, and it was found that the acceptable upper limit of gestation length for the Montbéliard and Simental breeds was 306 days, this being significantly different from other breeds. For the remaining dairy cattle breeds the value was 298 days. For cows with gestation length exceeding these limiting values, parentage control would be advisable.

Full textAbstract:
Feral cattle (Bos taurus) live in socially stable herds. Due to farm management practices, intensively managed dairy cows experience frequent regrouping, which can disrupt affiliative bonds and induce social stress. This study examines how changes in herd composition affect milk yield and udder health traits in resident dairy cows exposed to the withdrawal of herd members or the introduction of new individuals. Milk yield, electrical conductivity, and blood presence in milk were measured in 798 cows using precision dairy sensors over 9 years. Milk yield decreased significantly (p < 0.001) one day after the removal of familiar herd members, while introducing cows had no effect. A higher number of cows being withdrawn (up to 10) was associated with reduced milk yield (p < 0.001), elevated milk electrical conductivity (p = 0.01), and an increased prevalence of blood presence in milk (p = 0.01), which can indicate potential udder health issues linked to social stress. Holstein Friesian, primiparous, and first-lactation-stage cows were more affected than Czech Simental and multiparous cows later in lactation. These findings underscore the influence of social stability on dairy cow welfare and productivity, emphasising the need for strategies to mitigate stress when herd changes are necessary.

(Effect of supplementation of vitamin E, Selenium and Zinc mineral against to nutrient consumption, production and quality cement simental cow)ABSTRACT. Simental bulls often experience a decline in production and semen quality in the rainy season, which have a higher humidity and high rainfall. This study aims to maintain nutrient consumption, production and semen quality Simental bulls during the rainy season through the supplementation of Vitamin E, Selenium and Zinc Minerals. The study was conducted in July-December 2012 at the Artificial Insemination Center (BIB) Unggaran. The research material used in this study were 12 males Simental cows BIB Unggaran grouped by age. The experimental design used in this study is a randomized block design (RBD) with 3 treatments T1 (ration + Vit. E), T2 (ration + Vit. E + Se), T3 (ration + Vit. E + Se + Zn) and 4 groups as replicates. Parameters measured were dry matter intake and nutrient consumption, production and semen quality. Cement production was measured from fresh semen volume during the study, whereas semen quality measured motility and concentration of spermatozoa from fresh semen. Data consumption of dry matter and nutrient intake obtained were processed using analysis of variance, followed by Duncan test. While data on production and semen quality were analyzed descriptively. The results showed that the combination of vitamin E supplementation, minerals Selenium and Zinc did not affect dry matter intake, total digestible nutriens and crude protein, but resulted in a decrease in the percentage of shelter, semen volume, sperm motility and concentration smaller than before treatment. Treatment T1, T2 and T3 resulted in a decrease in the number of shelter respectively 41,55%, 19,56% and 13,63% compared to before treatment, whereas a decrease in semen volume unchanged at 44,9 %, 43,7% and 40,99%. Sperm motility due to treatment T1, T2 and T3 respectively decreased by 55,87%, 22,10% and 13,63% compared to before treatment. In line with sperm motility, sperm concentration in treatment T , T2 and T3, respectively decreased by 49,16%, 22,85% and 14,88%. The conclusion is a combination of vitamin E supplementation, minerals Selenium and Zinc can prevent the decline in cement production, sperm motility and sperm concentration Simental bulls during the rainy season.

Full textAbstract:
The aim of this study was to determine the effects of a trace element solution applied to cows in the transition period on the levels of fatty acids in the transition period. The material of this study consisted of 20 clinically healthy 3-5 year old simental cows kept under the same care and feeding conditions. Pregnant cows used in the study were divided into 2 equal groups with 10 cows in each group. A single dose of 20 ml of a trace element solution was administered intramuscularly to the pregnant cows in the study group 3 weeks before the birth. Blood samples were taken for analysis at the time of trace element administration, the moment of birth and 3 weeks after birth. Serum samples were analyzed using gas chromatography-mass spectrophotometry (GC-MS) device. When the findings of the study were examined, the fatty acid levels determined 3 weeks before the birth in the group in which trace element solution applied were higher compared to the moment of delivery and the period 3 weeks after birth. In the control group, the fatty acid levels determined 3 weeks before the birth increased at the time of delivery, and the fatty acid levels determined 3 weeks after the birth remained higher than the levels determined 3 weeks before the birth. It was concluded that trace element supplementation applied to pregnant cows during the transition period prevented excessive increase in serum fatty acid levels during the transition period.

The aim of this study was ti investigate endocrine and metabolic characteristic of Simmental cows in dry period, early and mid lactation. Experiment was included 45 Simental cows: 15 in dry period (2 weeks before calving, period 1), 15 in early lactation (in firs week after calving, period 2) and 15 in mid lactation (4-5 month after calving, period 3). Frequency distribution analysis shows that most of the parameters takes a normal distribution of distribution, unless the value of the total lipids (early lactation), urea (early lactation), T3 (dry period and mid lactation), T4 (early lactation) and insulin (dry period). The moment of blood collection has a substantial impact on the value of hormones and metabolites, except for total protein, T4 and insulin. Significant F value and posthock LSD were significant for: glucose (F=25.44; LSD 1:2, 1:3, significantly higher concentrations of glucose the dry period), cholesterol (F=15.62; LSD 1:3, 2:3, significantly higher concentrations of cholesterol in the middle of lactation), triglycerides (F= 50.42 ; LSD 1:2, 1:3, significantly higher concentrations in the dry period), total lipids (F =27.89; LSD 1:3 , 2:3, significantly higher concentration in the middle of lactation), NEFA (F=10.74; LSD 1:2, 1:3, significantly higher concentrations in early lactation ), BHB (F=24.39; LSD 1: 2, 1:3, 2:3, significantly higher concentrations in early lactation), albumin (F=9.2, LSD 1:2, 1:3, significantly higher concentrations in the dry period ), urea (F=11.61; LSD 1:2, 2:3, significantly reduced concentration in early lactation), T3 (F=3.31; LSD 1:3, 2:3, significantly lower concentrations in dry period and early lactation), growth hormone (F=4,17; LSD 1:2, 2:3, higher concentrations in early lactation). Concentrations of hormones and metabolites in Simmental cows depend on whether the blood was taken during the dry period, early lactation and mid lactation. Differences in metabolite values indicate the existence of reduced food intake, a negative energy balance, the mobilization of lipids and altered functional status of hepatocytes in early lactation. Most of the studied parameters showed a normal frequency distribution. The absence of normal frequency distribution for some parameters, particularly during early lactation, may indicate high heterogeneity of cows in the process of adaptation to the periparturient period.

Livestock farming is an effort to breed livestock to obtain benefits or results in the form of products and income. The success of a livestock business depends on three elements commonly referred to as the production triangle, namely seeds, feed, and management. In addition, the techno-socioeconomic characteristics of livestock farmers greatly influence the development of livestock businesses and will later affect the income of livestock farmers. The aim of the research was to examine the injection of the prostaglandin F2α hormone on the estrus response and pregnancy in Ongole crossbreed and Simental crossbreed cows reared using intensive and semi-intensive rearing systems. The data obtained will be analyzed using analysis of variance (ANOVA) and if there is a real effect, continue with further testing with Duncan's Multiple Range Test. The results of research on the percentage of estrus after the first and second injection of the prostaglandin hormone can be seen in the table. The highest percentage of estrus was in the S1P2 treatment with a percentage value of 80% and the lowest percentage value was in the S2P1 and S2P2 treatments with a percentage value of 40%. The percentage of estrus after the second injection, the percentage value for all treatments increased and the percentage of estrus was highest in the S1P2 treatment with a value of 100%. The average value of onset of estrus after the second injection of the PGF2α hormone was lower than the first injection. The longest duration of estrus in the treatment after the first PGF2α hormone injection was in the S1P2 treatment with an average of 24.75 hours, while the longest duration of estrus in the treatment after the second PGF2α hormone injection was in the S2P1 treatment with an average of 25 hours. PO cattle and Simental crossbreeds injected with PGF2α gave no different estrous responses. Intensive and semi-intensive rearing systems provide no different estrous responses. Raising PO cows using a semi-intensive rearing system injected with PGF2α provides an estrous response and high pregnancy rates (60), to be one of techniques to breed cattle of PO cow and have good impact to the success of a livestock business

Determining the degree of correlation between two or more traits depends to a large extent on their manifestation. The knowledge of genetic and phenotypic correlations between body characteristics of the animal and product characteristics can help define the breeding goal, but also to define and harmonize the assessment criteria. Although the phenotypic and genetic correlations between the traits of body development and type and the milk yield show different degrees of variation, they should be taken into account in the final assessment of the breeding value of the animal so that the selection programs are more comprehesively defined. The examination of phenotypic correlations of linear assessment scores of the type, milk and fertility traits was performed on a total of 303 cows of the Simental breed in the first three lactations. The examination of phenotypic correlations included the following milk performance properties in the first three standard lactations: milk yield, milk fat content, milk fat yield, yield of 4% corrected milk; also fertility traits: age at current calving and service period in each lactation; while the linear type scoring included a group of traits: type or frame, muscularity, fundament, udder.

Heyvandarlığın intensiv üsullarla inkişaf etdirilməsi, bu sahədə çalışan alim və mütəxəssislər qarşısında duran ən vacib bir məsələdir. Çünki əhalinin ən vacib və keyfiyyətli zülalı olan ət, süd və digər bu kimi ərzaq məhsulları məhz heyvandarlıq sahəsində əldə edilir. Ona görə də Azərbaycan xalqını kifayət qədər ekoloji baxımdan təmiz heyvandarlıq məhsulları ilə təmin etmək üçün elmi araşdırmalara böyük ehtiyac var.

For this purpose, productive breeds of beef and dairy cattle such as Holstein-Friesian, Swiss, Simmental, Aberdeen-Angus, Hollaway, Charolais and Limousine are imported and bred. Intensive livestock development is one of the most important issues facing scientists and specialists working in this field. Because meat, milk, eggs and other such food products, which are the most important and high-quality protein for the population, are obtained in the field of animal husbandry. Therefore, there is a great need for scientific research to provide the people of Azerbaijan with environmentally friendly livestock products. Different options are used for this purpose. As in developed societies, the production of agricultural products in the Republic, including in the field of cattle breeding, is carried out in accordance with the modern requirements of scientific and technological progress, ie on an intensive basis. Given that the import of productive breeds of cows from abroad cannot last long, because the ability of imported breeds to adapt to the territory of the republic is relatively low, these animals face certain complications. This reduces their economic efficiency. Therefore, it is considered expedient to use biotechnological methods tested in world practice to increase the productivity of local breeds and improve the sex composition existing in our country. Key words: rituals, milk productivity, quickly maturing, improving the composition of the breed, intensive care, new type, the seed of the perpetrators

In our study, it is aimed to compare melatonin hormone and vitamins A, E, D3 of goats, sheep and cows milk. Our sample consisted of 20 Simental Breed Cows, 20 Akkaraman Sheeps, and 20 Native Breeder Goats. Melatonin hormone was analyzed with Enzyme Plate Reader by using Rel Assay branded kit and to determine vitamin�s levels high-performance liquid chromatography (HPLC). Goat milk melatonin level was at the highest level at night and summer. Regarding goats` milk, Retinol and tocopherol levels were higher in spring than in summer. Regarding sheep�s milk, the melatonin level in the sheep`s milk was most elevated at night and spring. There were also statistically significant differences between spring and summer milk of sheep in terms of Retinol, Tocopherol, and Vitamin D3. Retinol and tocopherol levels were higher in spring than in summer, but vitamin D3 was higher in summer than in spring. Regarding cow`s milk, the amount of melatonin in milk was highest in winter and least in autumn. The amount of melatonin in spring was found to be higher than the amount of melatonin in summer. The amount of melatonin in spring was near to the amount of melatonin in winter, so there was not a statistical significance between them, and the amount of melatonin in summer was near to the amount of autumn, and no statistical significance was found between them.

Full textAbstract:
The recipe of mineral-vitamin premix, made on the basis of salts of mineral elements (Cuprum, Zinc, Cobalt, Iodine and Selenium) and fat-soluble vitamins (A and D), which are deficient in the Pre-Carpathian zone, has been developed and its influence on individual metabolic links and productivity of dairy cows has been investigated. The experiment was conducted on two groups of highly productive cows of Simental breed, analogues in origin and productivity in the summer-pasture period of keeping. The main diet for animals of both groups consisted of pasture grass, mowed mass of cereal-bean mixtures of green conveyor, hay cereal-mixed grass, molasses and standard feed K 60-32-89 with premix P 60-5M. The experimental group received a similar amount of this feed, but with an experimental mineral-vitamin premix. It was found that in the herbal-concentrate type of diet in the control group, the deficiency of Cuprum, Zinc, Cobalt, Iodine and Selenium was 16.6, respectively; 13,2; 6,9; 26,2; 51.8%, and the deficiency of vitamins A and D - 60.0 and 16.3%. Introduction of mineral-vitamin premix into the compound feed, which contained salts of the specified elements deficient for the Pre-Carpathians, made it possible to better balance the rations according to the mineral part, which significantly influenced both the intensity of metabolic processes in the rumen and blood, and the milk productivity of cows and the quality of milk. In particular, the positive effect of its feeding on the level of fermentation, the activity of enzyme systems and the intensity of synthetic processes in the rumen of cows of the experimental group was noted. The study of the hematological picture showed a tendency to increase the level of red blood cells and hemoglobin in the blood of cows of the experimental group, an increase in the concentration of nitrogen fractions and urea (P < 0.01). Analyzing the results of research, it can be argued that ensuring the optimal level of mineral-vitamin nutrition led to an increase in the intensity of metabolic processes in the body of animals and therefore contributed to an increase in dairy productivity.
 The average daily yield of natural milk in the experimental group for 90 days of the accounting period was 21.6 kg and was 10.8% higher than in the control (19.5 kg). The chemical composition of milk of cows that received a mineral-vitamin premix as part of the feed was preferable. It showed a probable increase in the content of dry matter, total protein (P < 0.05) and calcium (P < 0.02).

Full textAbstract:
Cattle are an essential source of animal food globally, and each country possesses unique endemic cattle races. However, categorizing cattle, especially in countries like Indonesia with a large cattle population, presents challenges due to costs and subjectivity when using human experts. This research utilizes Computer Vision (CV) for image data classification to address this urgent need for automatic categorization. The main objective of this study is to develop a mobile-friendly model using CV techniques that can accurately detect and classify Indonesian endemic cattle races, such as Limosin, Madura, Pegon, and Simental. To achieve this, an object localization approach is employed to extract multiple features from distinct regions of each cattle image, including the head, ear, horn, and muzzle areas. The authors evaluate two CV algorithms, ResNet50 and MobileNetV2, to assess their performance in cattle race classification. The dataset used is facial photos of 147 cows. The results indicate that ResNet50 outperforms MobileNetV2, achieving a training data accuracy of 83.33% compared to MobileNetV2's 77.08%. Moreover, the validation accuracy of ResNet50 (76.92%) significantly surpasses MobileNetV2's (38.46%). The novel contribution of this research lies in developing a cost-effective and efficient solution for identifying endemic cattle breeds in Indonesia. The mobile-friendly model based on ResNet50 demonstrates superior accuracy, enabling cattle farmers and researchers to categorize cattle races with higher precision, reducing manual effort, and minimizing costs. In conclusion, this research provides a valuable advancement in automatic cattle categorization using CV techniques. By offering a practical and accurate model that considers Indonesia's specific cattle breeding conditions, this study contributes to the sustainable management and conservation of endemic cattle races while enhancing the efficiency of cattle farming practices.

The decrease in fertility is considered to be the main cause of reproductive loss in dairy cattle and beef industry. Many candidate genes that play an important role in fertility and embryonic development. The purpose of this study was to detect genetic variations of the growth hormone gene family (GH|MspI, GH|AluI, GHR| AluI, GHRH|HaeIII and Pit-1|HinfI) and its association with superovulation response, ovulation, fertilization and transferable embryos rate. A total of 45 blood samples taken from cows that have been superovulated Angus, Brahman, HF, Limousin and Simmental. DNA was extracted with phenol-chloroform protocol followed by polymerase chain reaction technique (PCR) using specific primers for GH, GHR, GHRH and Pit-1 gene. PCR product was cut with restriction enzyme MspI, AluI, HaeIII and HinfI and electrophoresed on agarose gel and stained with ethidium bromide (EtBr). Superovulation is done by injecting a totally of 20 ml FSH for 4 days. Injecting the prostaglandin hormone (PGF2α) was performed on the eleventh day of CIDR implantation. Artificial insemination (AI) performed two or three days after the injection of PGF2α and Flushing was done on the seventh day after the AI.  The results showed that the Angus, Limousin, Brahman and Simental GH loci diversity of GH|MspI, GH|AluI, GHR|AluI, GHRH|HaeIII and Pit-1|HinfI was not associated with superovulation response, ovulation, fertilization and transferable embryo rate. In HF dairy cattle, genotype on Pit-1|HinfI AA has higher percentage of superovulation response (P 0.05) when compared to AB genotype, but did not differ to BB genotype. Dairy cattle HF AA genotype also had higher ovulation rate (P 0.05) when compared to AB and BB genotypes, but AB and BB have the same ovulation rate. Key Words: Polymorphisms, Growth Hormone Genes and Reproduction traits.

Full textAbstract:
In this study, some environmental factors thought to be effective on 305-day milk yield in Simmental cows, were examined according to the decision tree method with regression tree algorithm. For this purpose, the effect levels of calving interval, somatic cell count, calving age, and parity variables on the 305-day milk yield of 148 Simental cows were determined. As a result of the decision tree application, the factors affecting 305-day milk yield were found as parity, calving age, somatic cell count, and calving interval, in order of importance. In addition, it was determined that the 305-day milk yield of the cows with the calving age above 5 was high, and the cows with the somatic cell count greater than 104.500 were found to be the lowest. There is a need to use the decision tree approach in order to examine the effects of other environmental factors that are thought to be effective on milk yield or other economic characteristics in dairy farming and to provide appropriate conditions by correcting the relevant factors accordingly.

Full textAbstract:
Studies are focused in monitoring 12 farms during the years 2015-2017 and aim to prove prognostic value of changes in haemato-biochemical indicators in cows affected by the “downer” syndrome. For the study period “downer” syndrome was found in 47 cows (4.89%) of average age 7±0.6 years and in the pre-calving period (82.97%). Most affected were Speckled cows (53.19%), Simental (29.78%) and interbreeding (10.02%). In 36.17 % of cases cows ended in slaughter. “Downer” syndrome in cows dictates changes in haemato-biochemical indicators that might be used for prognostic purposes. Raising indicators are the amount of albumin (4.1 ± 0.7g/dl from 2.1-3.6 g/dl), the total of white cells (16.0 ± 0.8 x 103/µl from 4-12 x 103/µl) and number of neutrophils (65.2 ± 5.1 x 103/µl out of 15-47 x 103/µl). Indicators that decrease are the overall calcium (1.58 ± 0.2 mmol/l from 2.43 - 3.10 mmol/l), inorganic phosphorus (0.98 ± 0.2mmol/l from 1.08 - 2.76 mmol/l), magnesium (1.32 ± 0.1 mmol/l from 0.74 - 1.10 mmol/l) and number of lymphocytes (23.9 ± 2.1 x 103/µl from 45.0 - 75.0 x 103/µl). Changes in haemato-biochemical indicators are recorded since days 3-5 and can be used to control the clinical status and prognosis in cases of cows affected by the “downer” syndrome.

Background: An apicomplexan protozoon Neospora caninum, causative agent of neosporosis, is recognized as one of the most common and important cause of sporadic and endemic bovine abortion and reduced reproductivity in dairy and beef cattle worldwide. The present study was conducted to investigate the relationship between N. caninum seroprevalence and infertility problems in 400 cows in Burdur city, Turkey.
 Methods: Blood samples were collected from vena jugularis into sterile serum tubes from 49 aborted, 58 infertil, 48 pregnant and 245 healthy cows for the findings of reproductive anamnesis during a period of March 2010 to March 2011. Sera samples were analyzed by competitive ELISA kit.
 Results: The seroprevalences were 7.7%, 6.4% and 4.2% in 2-4, ≤2 and ≥4 age groups respectively and no statistically significance observed between age groups. Seropositivity rates were 5.7%, 5.1%, 4.5%, 3.6% in Holstein, Montofon, cross-breeds and Simental breeds respectively. Seroprevalence differences was not statistically significant among cattle breeds. Antibodies to N. caninum were found in rates of 16.3%, 6.9%, 6.3%, 2.4% in aborted, infertile, pregnant and healthy cows respectively and there was a significant difference (P<0.01) between aborted and healthy animals. Seroprevalences were Yeşilova 10%, Gölhisar and Ağlasun 8%, Bucak, Çavdır and Kemer 4%, Karamanlı and Burdur Centrum 2%, according to districts.
 Conclusion: The seroprevalence of N. caninum was revealed in Burdur region. It was emphasized that N. caninum infection should not be ignored in reproductive problems, especially in abortion cases.

This study was conducted to examine the milk yield traits of Holstein Friesian (HF), Brown Swiss (BS), and Simmental (SM) breeds, as well as their crossbreeds raised in enterprises registered in the herdbook system in Türkiye. With this study, the performances of cattle breeds and their crossbreeds widely raised in Türkiye were compared in terms of milk yield characteristics based on agricultural regions of Türkiye. The data used in the study included the completed lactation records of 22 331 heads of cattle for the years 2000-2014. The GLM ANOVA method was used in the statistical analysis of the effects of breed, genotype, and region on traits related to milk yield. Across the herd, the mean and standard deviation values were determined as 7551±2771 kg for lactation actual milk yield (AMY), 4.2±1.8 for total lactation number (TLN), and 382.9±9.2 days for lactation period (LP). The effects of genotypes and regions were found to be significant or very significant (p&lt;0.05 or p&lt;0.001) for all three studied traits, region x genotype interaction was found to be very significant for AMY and TLN (p&lt;0.001), and not significant for LP (p=0.184). As a result, it was revealed that the interaction effects of genotype, region, and genotype x region should be taken into account in determining the milk yield traits of cultured breed and crossbreed cows that are widely raised in Türkiye. Accordingly, it was concluded that the interaction findings should be evaluated in determining the breed preferences by the regions.
