Background: The objectives of a series of studies undertaken was to improve farm animal reproductive efficiency in terms of embryo production efficiency, conception rate and litter size by immunoneutralization of inhibin in conjunction with other conventional reproductive techniques. Materials and Methods: A recombinant porcine inhibin alpha-subunit mature peptide was produced by mass scale and...

Artificial insemination program to increase production is affected by oestrus. Breeders generally identify cows in oestrus based on their behavior. Currently, can be predicted and scheduled due PGF2α synchronization. This study aims determine the detection of after synchronization, more specifically distinguish audio-visual The six used were synchronized using PGF2α. Descriptive methods include...

The use of exogenous gonadotrophins in puberty inducement and ovulation synchronization is a technique that has a positive influence on the management of swine. The purpose of this study was to verify the effects of a second gonadotrophin treatment [equine chorionic gonadotrophin (eCG) and luteinizing hormone (LH), intramuscularly (i.m.)] upon the second oestrus synchronization and fertility in...

The study aimed to evaluated the reproductive performance response to short term oestrus synchronization during the transition period. One hundred and sixty-five indigenous multiparous non-lactating goats were subdivided into the following six treatment groups for oestrus synchronization: NT control Group (N= 30), Fe-21d, FGA vaginal sponge for 21days+eCG at 19d; FPe11d, FGA 11d + PGF2α and eCG...

Ucar O. , M. Kaya, S. Yildiz , F. Onder , M. Cenesiz , M. Uzun: Effect of Progestagen/PMSG Treatment for Oestrus Synchronization of Tuj Ewes to be Bred after the Natural Breeding Season. Acta Vet. Brno 74, 2005: 385-393. The aim of this study was to investigate the effect of pregnant mare serum gonadotrophin (PMSG) and progestagen sponge on oestrus synchronization of Tuj ewes mated after breedi...

This experiment was carried out on 123 Farahani ewes from a herd in Delijan city in Markazi province of Iran to determine the best short-term method for oestrus synchronization. Ewes were divided into five experimental groups randomly: group 1) use of controlled intervaginal drug release devices (CIDR) for 7 days with intramuscular (IM) injection of PGF2α on zero day and IM injection of 500 IU ...

Synchronization of bovine oestrous cycles was studied with respect to methods of accomplishment. A total of 328 cows were re¬ cycled by: {a) daily subcutaneous injections of progesterone, {b) larger subcutaneous injections every 3rd day and {c) corpus luteum expression. Standing oestrous was exhibited by 262 cows. Twelve did not exhibit oestrus and fifty-four exhibited symptoms but refused moun...

Ustuner B., U. Gunay, Z. Nur, H. Ustuner: Effects of Long and Short-Term Progestagen Treatments Combined with PMSG on Oestrus Synchronization and Fertility in Awassi Ewes During the Breeding Season. Acta Vet. Brno 2007, 76: 391-397. Synchronization of oestrus has been used to increase reproductive effi ciency in most animals, including ewes. The aim of the present study was to compare the effec...

Fifteen nulliparous and nine multiparous Serrana goats were used, through two successive oestrous cycles, in order to characterize their ovulation time with regard to the number of ovulations after induced and natural oestrus during the breeding season. The onset of oestrus was detected by the amount of vasectomized bucks after oestrus synchronization with prostaglandin, given 10 days apart, an...
