Ovsynch senkronizasyon protokolü östrojen tespiti olmadan zamanlanmış suni tohumlama sağlayan pratik bir yöntemdir. Östrus ve yumurtlamayı senkronize etmek için süt ineklerinde yaygın olarak uygulanır. Bu çalışmada Holştein ırkı ineklerde ile β-karoten enjeksiyonun döl verimi üzerine etkisi araştırıldı.

Administration of recombinant bovine somatotropin (bST) to lactating dairy cows during heat stress increases milk yield, but it also can increase body temperature and may therefore compromise fertility. However, it is possible that bST treatment could increase fertility during heat stress because it has been reported to increase fertility in lactating cows. In addition, bST increases secretion ...

This current study aimed to determine ovarian and luteal blood flow waveform patterns in buffalos synchronized using OvSynch protocol cold hot seasons. Six cyclic buffalo cows aged 6±0.5 years old, having a weight of 400 ± 50 kg, were scanned daily along three successive estrous cycles transrectally by Doppler ultrasonography evaluate the normal hemodynamic during spontaneous ovulation before s...

The present experiment was designed for estrus induction in post-partum anestrus cattle. A total of 120 cows were examined reproductive status, and 30 incorporated induction, including 24 6 normal cyclic cows. assigned to 5 groups (6 animals per group). group-1 induced using Ovsynch protocol, while group-2 inserted TRIU-B (958 mg progesterone) intra-vaginal inseminated at a fixed time. group-3 ...

Two experiments were conducted to determine the effect of estradiol cypionate (ECP), when incorporated into a conventional GnRH-PGF(2alpha)-GnRH timed artificial insemination protocol (Ovsynch), on systemic estradiol (E(2)), time and incidence of ovulation, luteal development, and conception rate in Holstein cows. Our objective was to determine if administration of 0.25 mg of ECP at the time of...

Aim: The aim was to evaluate the estrus response, conception rate and plasma profile of progesterone, protein and cholesterol following use of different hormonal protocols in anestrus and repeat breeding buffaloes. Materials and Methods: This study was carried out on 20 true anestrus, 20 repeat breeders, and 10 normal cyclic buffaloes. Ten anestrus buffaloes each were treated with standard cont...
