متن کاملComparison of ovsynch and progesterone-based protocol for induction of synchronized ovulation and conception rate in subestrous buffalo during low-breeding season
The objective of the present study was to compare the impact of ovsynch and progesterone-based ovulation synchronization protocol on ovarian response and conception in buffalo (n=19) exhibiting subestrus during low-breeding season (maximum ambient temperatures and relative humidity ranging from 36-45°C and 30-80%, respectively). Group I buffalo (n=10) were administered ovsynch protocol (d 0 and...
