Abstract:
In an attempt to assess the possibilities of improvement in production performance of Kankrej cattle by supplementation of vitamin E and Selenium, an experiment was conducted to investigate the effect of vitamin E and Selenium during transition period in Kankrej cows. A total of 24 cows were selected on the basis of their milk yield, parity and body weight are grouped into four homogenous treatment groups of 6 each. Out of these, one group served as control fed as per NRC (2001) wherein no supplementation was given. Cows in treatment groups, Group-1 vitamin E, Group-2 selenium and Group-3, vitamin E + Selenium supplementation were given daily along with control diet. Lactose percentage of milk differed significantly (P<0.01) between groups but lactose percentage among groups differed non- significantly between different days of lactation period. The interaction effect including group x days was found non- significant.
