Abstract

The present study was undertaken to investigate the effect of breed groups
and age of different dairy cows on conception rate under commercial dairy
farming in Chittagong area. Three cattle breed groups, namely: Holstein ×
Local, Sahiwal × Friesian and Local were found in the farm surveyed. The
percentage of the cows of Holstein × Local and Local was higher (50%) than the Sahiwal × Friesian (46.6%). The Holstein × Local had a higher productive life (up to 9 years) than Sahiwal × Friesian and Local breeds. The service per conception also differed significantly between the breed groups. The conception rate of Holstein × Local, Sahiwal × Friesian and Local was 60.37±25.68, 39.08±17.69, 86.1±19.66 percent, respectively, and differed significantly among the breed groups.
