Abstract

The present study was undertaken to understand the role of age, body condition score and rump fat thickness on quality semen production of Murrah bulls. One hundred thirty Murrah buffalo breeding bulls at five different semen stations of Haryana and Punjab were selected. Age of bull was recorded by calculating the days between date of birth to day of experiment. Body condition score was recorded by visual observation and palpation of seven skeletal check points on 1-5 scale. Rump fat thickness was measured in 38 bulls by ultrasonography. Semen quality attributes viz. ejaculate volume (EV, ml), mass motility (MM, 0-5), sperm concentration (SPC, million/ml), sperm motility (%), sperm viability (%) and sperm abnormality (%) of each ejaculate were recorded. The bulls were divided into three groups on the basis of Age; and two on the basis of Body Condition Score (BCS) and Rump Fat Thickness (RFT). Results revealed that EV, MM (P
