Effect of body-weight and age at calving on milk production in crossbreds (Holstein x Sahiwal) as compared to Sahiwal cattle. I. Effect of body-weight on milk production



Effect of body-weight and age at calving on milk production in crossbreds (Holstein x Sahiwal) as compared to Sahiwal cattle. I. Effect of body-weight on milk production



Indian J. vet. Sci 36: 72-79



Body weights within 1 wk. of calving and the 300-day milk yield in the subsequent lactation have been studied for 270 Holstein x Sahiwal cows in the southern region (S.R.) and 306 crossbred plus 162 purebred Sahiwals in the northern region (N.R.) of India. Milk yield increased with the proportion of Holstein blood up to & in the S.R. and 0.75 in the N.R. Over 6 lactations the crossbreds were superior to Sahiwals in adaptability and milk production.
