Abstract


The aim of this study was to investigate the effect of live yeast culture (Saccharomyces cerevisiae Sc 47) on milk yield, milk composition and some blood parameters of dairy cows during their early lactation on farm conditions. The live yeast culture was given in the diet of heifers and cows (5 g day-1 solid Actisaf) for 14 days before calving and exclusively for the treated cows 12 g day-1 dissolved in 500 ml of water, during 14 days after calving. The experiment took until 100th day of lactation on farm conditions. Yeast culture supplementation was the most effective for the performance of primiparous cows: It was advantageous for blod plasma parameters: decreased the beta-hydroxy butyrate (BHB) content and free fatty acids (FFA) which indicated the protection of the animals against ketosis or other metabolic disorders. Increased the daily milk production and the lactose /glucose content of the milk. The live yeast culture increased the lactose content of the milk and decreased the somatic cell count of multiparous cows. The listed parameters were not significant (P<0.05) compare to the results of positive control groups. The applied live yeast culture supplementation did not significant affect for other performance of the cows.
