Effect of yeast culture “Saccharomyeces cerevisiae” on some biochemical parameters of blood and milk composition in early lactating goat.
Abstract: This study was conducted to evaluate the effect of yeast culture Saccharomyces cerevisiae (SC) on some blood parameters and milk composition in late pregnant and early lactating Egyptian goat. Ten multiparious pregnant Baladi goat were allocated into two groups (5 does each) aged 2-3 years and weighing 30-40 kg. The experiment was initiated in the last month of pregnancy till two months postpartum. The control group fed on basal ration without any treatment and the second group fed on the same diet supplemented with 0.25 gm/ head/ day of dry live yeast culture. Blood and milk samples were collected from each animal in the early morning every two weeks all over the trial period. The results revealed that, blood lactic acid dehydrogenase (LDH), lipid peroxidase and nitric oxide levels in the yeast culture SC treated group were significantly lower (P˂0.01) than those of control one. There was a significant increase (P˂0.01) in blood glutathion-S-transferase (GST) level. There was a significant increase (P˂0.01) in percentages of fat, protein, lactose and total solids in colostrum and milk of the yeast culture SC supplemented goat than the control ones. There was significant decrease (P˂0.01) in percentages of urea and somatic cell count(SCC) in the treated group compared with control ones. The lamb mortality rate was zero in the treated dams as compared with the lambs of the control ones (62.5%). The yeast culture SC supplementation led to significant increase (P˂0.01) in weight gain of the lambs at weaning compared with that of the control ones. In conclusion, using of the yeast culture SC in early lactating goat as a supplement had a beneficial effect on some blood parameters; increased antioxidant and decreased free radicals and improved milk constituents that led to increase productivity of the dams and lower the lamb mortality rate.
