Abstract

Successful adaptation to metabolic changes associated with transition from non-lactating pregnant state to non-pregnant lactating state is very important in economic dairying. Though feeding and management plays an important role in adaptation to transition, animals kept on similar feeding and management exhibit difference in adaptation indicating an underlying genetic cause. In the present study, a comparison of the sequence of DNAJC30 gene, which has been reported to influence metabolic adaptability, between Serum β hydroxy butyrate (BHBA) - high and low groups revealed four variations downstream to its exonic region. Whether these changes influence the metabolic adaptability of animals need to be ascertained in a large population.
