In the past few decades, research guided genetic selection and nutrition programs have had a major impact on improving carcass composition and efficiency of production in swine. The use of artificial insemination also had a major impact on pig improvement in the past few years. This research is conducted to assess the reproductive performance and managemental advantages of Artificial Insemination of swine. The reproductive pCrfoftnanCe in t$ o groups of animals (one receiving AI and other by natural mating) was studied after maintaining the sows under optimal managemental conditions. The results indicated that both AI and natural mating practices showed 100% conception rate. The litter size of AI group was 8.36±0.28 and that of the natural mating group was 10.6±0.64, which varied with high significance. The still birth rate was 0.7±0.26, which was significantly higher in natural mating group. The pre-weaning mortality was 4.34% and 7.5% for AI group and natural mating group respectively. The time consumed during mating per sow also varied highly significantly which was 11.46±0.47 minutes and 51,2±2.08 minutes for the AI group and natural mating group respectively. It was found that AI was found to be time and labor saving and AI can be successfully introduced in field conditions with some fine tuning. [ABSTRACT FROM AUTHOR] |
