摘要

Synchronization of oestrus in Osmanabadi goats was carried out by using different hormones. The objective of the present study was to evaluate mean time interval for exhibition of oestrus, duration of oestrus, conception rate and biochemical changes of serum total protein and serum cholesterol before and after treatment and in control groups. It was observed that the efficacy of PGF_2 alpha for synchronization was 50 percent by IM route, 75 percent by IVSM route. The efficacy of progesterone and PMSGwas 60 percent. The conception rate 60.0, 66.67 and 50.0 percent in group I, II and III, respectively. Serum total protein did not show appreciable change in treatment and control groups both before and after treatment. However, the serum cholesterol level was found to be higher after injection in treatment group between 24 to 72 hrs.
