Effects of artificial insemination on some performance characteristics of goats

This study aims to determine the effect of artificial insemination on some reproductive performances in Alpine does. This study was carried out from August 2016 to September 2017 in the Çukurova University, Faculty of Agriculture and Dairy Goat Research Farm located in the province of Adana in the East Mediterranean Region of Turkey. Sixty reproductive Alpine females have been involved in this study. Goats were divided into two: 30 does were naturally bred using well performing males (control group) and the other 30 does were artificially inseminated (trial group). Throughout the experimentation does were synchronized using vaginal sponge impregnated with 20 mg of progestagen FGA (fluorogestone acetate, Chronogest CR, Intervet, France). Animals in standing oestrus were inseminated by intra-uterine method in trial group (AI) while the natural mating method was applied in control group. The physiological adaptation parameters were also recorded in two groups. The work showed that the oestrus synchronization followed by natural mating achieved higher fecundity, survival rate and birth live weight (3.83 ± 0.23 vs. 3.15 ± 0.11) than the use of intrauterine AI after oestrus synchronization in goats. However, the AI animal allows an acceptable twining rate (1.82 vs. 2.14). The physiological parameters of both groups are similar but different during the day.
