The effect of dietary supplementation with dry bakery yeast culture Saccharomyces cerevisiae in high concentrate diet (F:C=47:53) on milk yeald and rumen fermentation were studied on two groups primiparous lactaiting cows (8 cows per group) and four ruminally cannulated nonlactaiting cows on diet
F:C=25:75. Cows fed yeast during 67 days produced 1.24 kg/d and 1.66 kg/d natural and 4% fat corrected milk respectively more, than control cows. Milk protein and fat percentages were also higher. On diet with yeast ruminal concentration of lactate was lower and butirate+propionate was higher. The yeast
incrised rumen pH, decreased NH3 in rumen and urea in blood, decreased viscosity of rumen fluid
In this article, we discussed the problems of the metabolic disease of cows in peripartum period and profitability of the consequent lactation. The article has materials about adaptation in postpartum and arise ketosis, acidosis, laminit and reproductively reasons
