Abstract
Progress of production in dairy cattle is frequently considered possible by either improving the genetic merit and/or by husbandry practices. The aim of the research is to evaluation of productive and reproductive performance of dairy cows considering genotype was undertaken in greater Rajshahi from July, 2007 to June, 2009. A total 335 farmers data and 671 numbers of cows were considered for assessed in the local (L), Local x Friesian (LF), Local x Sahiwal (LS),Local × Friesian× Sahiwal(LFS) and Local × Jersey (LJ) dairy cows raised in randomly selected smallholder dairy farms and Duncan multiple range test for statistical significance. The overall mean values of age at puberty (month), age at first service, age at first calving (month), service per conception (s/c), post-partum heat period (days), days open (days), wastage days (days), gestation length (days), milk yield per day (liter), lactation length (days), milk yield per lactation (liter), weaning period (days), dry period (days), calving interval (days) and birth weight of calves (kg) were 26.37±.22, 26.56±0.23, 37.84±0.25, 1.43±.36, 85.83±1.57, 117.85±2.35, 13.33±1.02, 279.90±.33, 5.35±.12, 277.00±1.73, 1390.45±33.50, 213.21±2.35, 91.34±1.47, 398.81±2.34 and 22.51±.21, respectively in different genotypes of cows. Considering the overall performance it could be concluded that Local×Sahiwal×Friesian (LSF) crossbred cows are more suitable for sustainable and profitable dairy farming in greater Rajshahi region.
