Influence of feeding regime on semen quality and conception rate of Black Bengal goat's by artificial insemination under the semi-intensive system

Abstract

The research work was conducted to study the quality of semen using two different feeding regimes and the conception rate by artificial insemination of Black Bengal goats under the semi-intensive system. The Black Bengal goats were fed with two types of concentrate supplements and grazed them in the field for 5 to 6 hours per day for a period of 6 months. Semen from bucks was collected using an artificial vagina, and the collected semen was evaluated for physical and microscopical tests (total sperm cell counts by hemocytometer, normal and abnormal sperm counts, and live and dead sperm cell counts). For the total count, 3115 to 3120 million sperm per ml, 82% to 87% live sperm, and 85 to 88% normal sperm cells were observed from the Black Bengal bucks. Goats were artificially inseminated using a vaginal speculum and a locally developed inseminating device, and it was found that about 50% of goats were conceived.
