Abstract

The objective of this study was to determine the effect of GnRH administration and using different levels of equine chorionic gonadotrophin (eCG) on REPRODUCTIVE PERFORMANCE of RAIENI GOATS. A total of 100 RAIENI GOATS (45.5±3.6 Kg) with a body condition score (3-3.5) in completely randomized design, were allocated into five groups. Synchronization of estrus was done using CIDR for a 14-day period. 20 goats in first group were kept as the control and other treated goats were injected intramuscularly 2.5 ml GnRH (T2), 2.5 ml GnRH with 150 IU ECG (T3), 5 ml GnRH with 300 IU ECG (T4) and 5 ml GnRH with 450 IU ECG (T5). During 24 to 48 hours after removal CIDR, the goats came into estrous using of 10 aproned bucks at the time of mating. The results showed that the estrus incidence rate was significantly different in control groups compared with other treatment (p>0.05). The pregnancy rates were 89.24, 93.17, 99.56, 100 and 85.61 % in treatments and control group respectively in which the pregnancy rate in T5 was significantly higher than the other groups (p<0.05). Twinning rate was significantly lower in control group compared to other treatments. The results of the present study showed that ECG treatment with GnRH hormone can increase REPRODUCTIVE PERFORMANCE in Iranian RAIENI GOATS.
