Supplementing yeast culture to beef heifers consuming a forage-based diet.

ABSTRACT: This experiment evaluated the effects of supplementing yeast culture (YC; Saccharomyces cerevisiae) on in situ ruminal degradability, rumen fermentation and microbiota responses of heifers consuming a forage-based diet. Twelve ruminally-cannulated Angus-influenced heifers were ranked by body weight (BW; 180 ± 4 kg) and assigned to 4 groups of 3 heifers each. Groups were enrolled in a replicated 3 × 3 Latin square design containing 3 periods of 21 d and 14-d washout intervals. Groups were assigned to receive no YC (CON), or 1.5 g of YC/100 kg of heifer BW (YC1.5) or 3.0 g of YC/100 kg of heifer BW (YC3.0). During each period, heifers (n = 12/treatment) were housed in individual pens and offered water and bermudagrass hay (Cynodon dactylon) fo
