Abstract :The objectives of the present study were to determine the effect of adding Saccharomyces cerevisiae insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(P<0.05);. There is a significant difference between the control and the cows fed different treatments in somatic cells insert ignore into journalissuearticles values(P<0.001);. It revealed that higher of milk protein in three treated groups was recorded than in the control group. The milk lactose content seems to be stable in cows supplemented SC and was practically similar to control group. On the other hand, the content milk fat was low in SC supplemented cows. The bacterial milk analysis was lower for the cows fed supplemented SC than the control group. The obtained results showed that the SC from Algeria can improve the milk production in dairy cows during the postpartum.
