Abstract:

Female American lobsters, Homarus americanus, seldom are receptive to mating more than 24 h after they molt, a fact that complicates breeding programs in large facilities where animals are held individually. Artificial insemination can eliminate this problem, but preliminary studies have indicated poor fertilization success from intermolt inseminations. In the present study, 86 female American lobsters of wild and cultured stock were artificially inseminated in all postmolt and intermolt stages, 64 subsequently spawned, and 98% successfully fertilized their eggs, indicating no constraint of mo

Abstract:

Artificial Insemination (A.I) is an in vivo fertilization process to avoid sexual intercourse or in vitro fertilization. In this process sperm is introduced into a female’s cervix or uterine with the help of proper instruments for achieving pregnancy. A.I is used for human, pets, endangered animal species, livestock, animal in zoo etc. Although the A.I is very common for cattle (75% of all inseminations) and swine (85% of all inseminations).

By applying the technology of artificial insemination (AI) remarkable progress has been achieved in livestock production over the past 50 years. The basic requirement of modern livestock production is obtaining the maximum number of insemination doses per ejaculate, the possibility of long-term storage of the inseminated doses, as well as achieving the maximum fertility rate of inseminated females. Therefore, the aim of this paper is to present new findings on the modern technology of artificial insemination of domestic animals.

In our opinion, the higher percentage of fertile inseminations of firstborns is explained by the use of an automatic system for determining sexual desire at the farm "Kutuzivka".The season of the year was the most influential factor in the fertilization of the first-born cows among the factors of the external environment.

ABSTRACT Artificial insemination has been widely known among breeders as an effective reproductive technology by inserting sperm collected from male animals into the reproductive tract of female animals for the purpose of improving genetic quality. The success of AI is influenced by several factors, namely semen quality, inseminator expertise, livestock health, and other supporting factors. Good semen quality is one of the determining factors for the success of artificial insemination.

Abstract:

The article presents data on a rotary machine for artificial insemination of sheep with the function of fixing the head and, separately, the back of the trunk. The machine eliminates the need for capital structures and premises for artificial insemination of sheep, thereby reducing material costs when working with animals. The versatility of the design indicates its versatility, in addition, it is convenient to store and transport, and also helps to reduce the cost of manual labor by more than 2 times. Artificial insemination and other veterinary measures with the use of this machine become mo

Abstract:

In India major portion of goat farming is extensive and breeding system follows uncontrolled natural mating. For better breeding management there should be sufficient good quality stud bucks. But it is very unfortunate that due to lack of breeding buck more than 30% estrus does remain without service. In order to check the negative selection and for proper management of breeding policy, cryopreservation of superior native buck semen and artificial insemination is the only way. Artificial insemination (AI) is a part of assisted reproductive technology (ART) providing augmentation of genetic mak

Abstract:

An investigation was undertaken to study knowledge level of women dairy farmers on dairy animal management in Guntur district of Andhra Pradesh. A total of 225 randomly selected women dairy farmers in three animal husbandry divisions of Guntur district in Andhra Pradesh viz., Pedaravuru, Guntur and Narasaraopeta. The farm women in the study area had good knowledge regarding importance of Artificial Insemination (96.40%), followed by identifying the animals in estrus (95.10%), importance of treatment of anestrus and repeat breeding animals (92.90%), culling of unproductive animals (87.10%) and

Abstract:

Artificial insemination has arguably been the most important practice contributing to the advancement of animal production. The numerous advantages of artificial insemination are augmented when the semen is cryopreserved and conserved for long periods. Unfortunately, the utility of cryopreserved semen is limited because for most mammals, even cattle, a considerable proportion of sperm loose their fertility during freezing-thawing. In many species , this loss of fertility is substantial, rendering cryopreserved semen impractical for routine use. Our goals are to characterize the nature of the s

Abstract:

Artificial insemination of brushtail possums (Trichosurus vulpecula) is being developed as an assisted breeding model for endangered marsupials, as well as a bioassay for testing fertility control vaccines to manage overabundant populations. Procedures were optimised in animals superovulated with pregnant mare serum gonadotrophin (PMSG) and porcine luteinising hormone (pLH). Of three intervals examined, yields were maximal following uterine insemination at 27–29.5 h after pLH treatment (four eggs, two to three embryos per female). Compared with no insemination, uterine-inseminated animals ovul

As a result of achievements in genetics and in technology of artificial insemination` cattle breeders received a powerful instrument of improving animals productive qualities, the possibilities of selecting stallions with a high genetic potential of productivity were expanded` and the rate of genetic improvement of entire populations was accelerated. Sperm from stallions is taken on an artificial vagina. Evaluation of the quality of sperm is carried out for 3 consecutive days. Insemination of mares is carried out at artificial insemination stations. 10 days after ovulation the mares are checke
