Comparison of Hormonal Treatment Kisspeptin with GnRH and hCG on the some Reproductive Performance of Cyprus, Does during Non-Breeding Season

The current study was conducted to investigate the influence of Kisspeptin, GnRH and hCG on some reproductive performance of Cyprus does during the non-breeding season. A total 55 Cyprus does 2-6 years old and averages 45 kg body weight. The does were randomly divided into five equal groups (11 does per group). The first group (B1) regarded as a control group, intramuscular injection with normal saline, whereas, the second (B2) and third (B3) groups were injected with 4 and 8 µg / kg body weight of Kisspeptin-10 intravenous respectively. The fourth (B4) and fifth (B5) groups were injected with hCG (250 IU / doe) and GnRH (20 µg / doe) intramuscular respectively. Bucks were introduced after 24h of the treatment in all groups, ensuring that does exhibit estrus were mated for three consecutive estrus cycles. There were significantly in kilogram kids per goats joined in group B2 (2.84±0.05 kg) and then group B5 (2.45±0.04 kg) compared with other groups. The kilograms born per goat kidding (P< 0.05) was lower in group B4 than other groups. Gestation length was significantly longest in group B1 as compared with other groups. Results showed that there were no significant different (P>0.05) male kid weight and female kid weight. In conclusion, kisspeptin-10 (4 µg/ kg/ animal) enhanced kilogram kids per goats joined and then GnRH in Cyprus goat does during non- breeding season.
