Effect of feeding Saccharomyces cerevisiae on performance of dairy cows during summer heat stress
RGS Bruno, HM Rutigliano, RL Cerri… - Animal Feed Science …, 2009 - Elsevier
Effects of feeding a culture of Saccharomyces cerevisiae to lactating cows on their
lactational performance during heat stress were determined. Multiparous Holstein cows (n=
723) calving during the summer months from two dairy farms were randomly assigned to a
diet containing no yeast culture (control; n= 361) or 30g/d of a S. cerevisiae yeast culture
(YC; n= 362) fed from 20 to 140d in milk (DIM). Cows were milked twice daily and the
production of milk and milk components was measured every 2 weeks. Dry matter (DM) …
