ABSTRACT
This study was conducted with a view to investigate the productive and reproductive performances of non-descript and crossbred dairy cows in costal area (Barisal Division) of Bangladesh. For this purpose a total of 105 dairy cows were selected from rural farmers, of which 30 cows local (L), 49 cows Local x Friesian (LxF) and 26 were Local x Sahiwal (LxSL) crossbred dairy cows. The traits studied were age At First Heat (AFH), age At Cirst Calving (AFC), Services Per Conception (SPC), Post Partum Heat Period (PPHP), Daily Milk Yield (DMY), Total Lactation Yield (TLY) Lactation Length (LL) and Calving Interval (CI). From the result, it was revealed that age At First Heat (AFH), age At First Calving (AFC) and Services Per Conception (SPC) of LXF crossbred dairy cows were significantly (p<0.01) lower than other groups. Post Partum Heat Period (PPHP) of L x SL crossbred cows were significantly (p<0.01) lower. Average Daily Milk Yield (DMY), Total Lactation Yield (TLY) and LactationLength (LL) of LxF groups were 5.9±0.14, 1836.7±18.2 L and 339.2±7.4 days, respectively, which is significantly (p<0.01) higher than L and LxSL groups. The Calving Interval (CI) was found highest in L x F crossbred cows compared to others.
