Abstract

Progress of production in dairy cattle is frequently considered possible by either improving the genetic merit and/or by husbandry practices. The study aims to evaluate of productive and reproductive performance of dairy cows considering genotype at different selected dairy farms in Chattogram metropolitan area. A total of 80 crossbred dairy cows belong to four different genetic groups eg. Friesian × Local, Friesian × Jersey, Friesian × Sahiwal (25%) and Friesian × Sahiwal (50%) were randomly selected and their information regarding milk yield and other reproductive parameters were collected from farm record for a period of last five years (January 2015 to March 2019). The overall age at 1st heat and age at 1st calving differ significantly (p<0.05) among the breeds. The lowest age at 1st heat (15.5±0.81 months) and age at 1st calving (25.90±0.82 months) were found in Friesian × Jersey. There were no significant differences (p>0.05) was found in case of service per conception and calving interval. A significant difference (p<0.05) was found in the lactation length and birth weight of calves of different genotypes of dairy cows. The lowest post-partum heat period (89.10±1.50 days) was found in Friesian × Sahiwal (50%) and the highest (91.15±1.73 days) in Friesian × Local (25%). The milk yield of Friesian × Local differs significantly (p<0.05) with other genotypes. The highest milk yield (14.90±0.41 liters) was observed in Friesian (75%) × Sahiwal (25%) and the lowest milk yield (11.50±0.87 liters) in Friesian × Local. The highest birth weight of calves (14.27 ± 0.51 kg) was observed for Friesian × Jersey. The productive and reproductive performance of Friesian × Jersey cows was superior to the rest of the genetic groups under the study. Friesian × Local ranked the lowest and Friesian × Sahiwal (25%) and Friesian × Sahiwal (50%) performed nearly similar. It can be concluded that in intensive farming condition Friesian × Jersey crossbred cattle rearing is profitable under better management practices.
