Abstract

Scrotal biometry and ejaculate characteristics were studied in 25 Ongole breed bulls stationed in a Livestock
Research station and correlated them with fertility. The scrotal and testicular measurements revealed mature size
by 5 years of age. A significant difference was observed between bulls in relation to various ejaculate characteristics
like mass activity, initial motility, live sperm count and sperm abnormalities. The mean fertility rate to first insemination
was found to be 71.63%. I twas further observed that scrotal biometry, sperm concentration, progressive motility
and live sperm count were positively correlated to first Al conception rate in cows.
