摘要
采用孕酮(P4) +雌激素(E2) +马绒毛膜促性腺激素(eCG)方案(繁殖期,BS=15;非繁殖期,NBS=15)和发情双同步协议(BS=15;国家统计局= 15)。P4+E2+eCG与BS(分别为86.0 vs 80.0%)和NBS(分别为73.3 vs 66.6%)相比,P4+E2+eCG诱导的水牛的发情双同步反应更高(p < 0.05)。两组诱导发情期评分差异无统计学意义(p < 0.05),但受孕率较低(p < 0.05)。此外,P4+E2+eCG与发情双同步方案相比,妊娠率(诱导+自发发情)更好(p>0.05) (73.3 vs 63.3%)。此外,P4+E2+eCG与estrad双同步相比,方案开始与受孕之间的间隔时间更短(p < 0.05;13.9±1.3 vs 17.5±3.1天)。综上所述,在野外条件下,对于繁殖期和非繁殖期的水牛来说,P4+E2+eCG方案是一种更好的基于激素的策略。
A hormone-based therapeutic strategy to reduce non-productive period in anestrus buffaloes during breeding and non-breeding season under field conditions
Sixty anestrus Murrah buffaloes were evaluated for the success rate of progesterone (P4) + estrogen (E2) + equine chorionic gonadotropin (eCG) protocol (Breeding season, BS=15; Non-breeding season, NBS=15) and estradoublesynch protocol (BS=15; NBS=15). The buffaloes subjected to P4+E2+eCG had higher (p>0.05) estrus induction response compared to estradoublesynch during BS (86.0 vs 80.0%, respectively) and NBS (73.3 vs 66.6%, respectively). Estrus period score at induced estrus in buffaloes subjected to either of protocols in BS or NBS was not different (p>0.05), however, pregnancy rate was lower (p<0.05) in buffaloes exhibiting <50 estrus period score in comparison to those exhibiting >50 score. Further, pregnancy rate (induced + spontaneous estrus) was better (p>0.05) using P4+E2+eCG compared to estradoublesynch protocol (73.3 vs 63.3%). In addition, the interval between start of a protocol and conception in P4+E2+eCG was less compared to estradoublesynch (p>0.05; 13.9±1.3 vs 17.5±3.1 days). In summary, P4+E2+eCG protocol is a better hormone-based strategy compared to estradoublesynch for anestrus buffaloes during breeding and non-breeding season under field conditions.
