Performance of Different Genetic Group of Cows Under Bangladesh Condition

Abstract Text: This study was conducted at Sarsha Upazila in Jessore district of Bangladesh to capture a scenario of productive and reproductive performances of different genotypes such as Holstein-Friesian, Sahiwal, Sindhi cross with local, and indigenous dairy cows. Data were collected by live survey on 100 cows of which divided into 4 groups each consists of 25 animals. Results shows that age at first calving, service per conception, average daily milk yield and milk yield at different stages of lactation varied significantly (p<0.01) among the four genotypes, and the best performer was Holstein-local cross cows. It may be concluded that the resources at research site for dairy cattle production are promising and the Holstein-local cross cows performed the best, having the highest yield and the shortest interval from calving to estrus although they required 40% more services per pregnancy than the Sahiwal cross cows.
