Effect of yeast Saccharomyces cerevisiae feed supplement on milk production and its composition of lactating Holstein Friesian cows from Northern Algeria

Abstract

The objectives of the present study were to determine the effect of adding Saccharomyces cerevisiae (SC) yeast culture commercial on milk production, milk composition of lactating Holstein Friesian cows under Algerian conditions. A total of 16 lactating Holstein Friesian cows were used. The control group received basal diet without feed additives and the yeast, SC group received daily 2, 5 and 10 g/day per head. Individual milk samples were collected for analysis of milk composition and bacterial. The results of this experiment showed a significant high milk production in treated groups compared to control group (P
