Abstract:
Frozen semen of Murrah bull is extensively used for augmenting milk production among the local buffaloes in our country. The present study was undertaken to find out the correlation between various semen productions traits in Murrah buffalo bulls. The data on semen production traits like semen volume, initial motility and sperm concentration were collected for first and second normal ejaculates. The first and second ejaculates were pooled for the preparation of total doses of frozen semen per collection. The records of 4563 collections each for first ejaculate and second ejaculate from 53 Murrah bulls, spread over a period of five years from 1996 to 2000 were studied. Correlation co-efficient between various semen productions traits were calculated by standard procedure. The correlation coefficients between semen production traits were generally high and positive except between volume and sperm concentration for first ejaculate (-0.609) and second ejaculate (-0.294).
