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 regime and conception rate by artificial insemination of Black Bengal goat's under the semi-intensive system The Black Bengal goats were fed by two types of concentrate supplements and graze them on the field for 5 to 6 hours per day for a period of 6 months. Semen from buck was collected using artificial vagina and the collected semen was evaluated for physical and microscopical test (total sperm cell counts by hemocytometer, normal and abnormal sperm counts and live and dead sperm cell counts). For 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 by using a vaginal speculum and a locally developed inseminating device, and it was found that about 50% goats were conceived.
