Effect of maternal heat-stress on follicular growth and oocyte competence in Bos indicus cattle

The objective was to determine whether exposure of Gir ( Bos indicus) cows to heat-stress (HS) causes immediate and delayed deleterious effect on follicular dynamics, hormonal profile and oocyte competence. The cows were kept in tie-stalls for an adaptive thermoneutral period of 28 days (Phase I, Da...
