Abstract

Yaks are the main source of livelihood for the highlanders in India as major agriculture is meager in yak inhibiting tracts due to adverse agro-climatic conditions. Under field condition, the reproduction in yak is seasonal which could be due to lack of feed and stress rather than inherent characteristics. The aim of the study was to check efficacy of vitamin E and selenium parenteral administration during late gestation period on postpartal fertility in yak. Altogether 21 yak cows were randomly divided into 3 groups (two treatment groups and controls) with 7 animals each. The animals within both treated group received a commercial preparation containing DL- alpha Tocopheryl Acetate equivalent to Tocopherol (vitamin E) 50 mg/mL and Sodium selenite 1.5 mg/mL intramuscularly. Treated groups received the drug twice in 7 days interval 30 to 40 days prior to calving in the amount of 5 mL and 10 mL in group I and II respectively. The study showed that administration of vitamin E and selenium during late gestation can significantly (P<0.05) improve fertility in group II animals..
