Influence of Live Yeast Culture (Saccharomyces cerevisiae) on Milk Production and Composition, and Blood Biochemistry of Grazing Dairy Ewes during the Milking Period

A feeding trial was conducted to evaluate the influence of live yeast culture (Saccharomyces cerevisiae) on milk production, composition, and blood biochemistry of dairy ewes during the machine milking period. The control group (CD) was fed a concentrate mixture and hay and grazed twice daily, while the second (YS3) and third (YS6) groups were fed the same diet supplemented with 3 or 6 g of live yeast culture (Yea Sacc1026), respectively. The treated groups had significantly higher values (p p p p p 1026) at 6g/animal/day as appropriate for field conditions
