Effects of adding yeast culture or sodium bicarbonate to lactating Friesian cows diet containing fodder beet root silage on rumen activity and blood constituents

Abstract

Twenty one multiparous lactating Friesian cows were used to study the effect of adding yeast culture or sodium bicarbonate on rumen activity and blood constituents. Treatments were started three days post calving, cows were assigned randomly into three equal groups (7 cows each). Daily ration of G I (control) contained concentrate mixture, wheat straw as well as fodder beet root silage (FBRS) represented 30% of the required TDN. While the daily ration of the G2 and G3 was supplemented with 15g/day/head yeast culture or 150 g/day/head sodium bicarbonate, respectively. Results indicated that the supplementation with yeast culture improved (P<0.05) rumen pH, total VF A's. acetate production and rumen lactate. Blood analysis of G2 indicated that cows had higher (/P<0.05). T3 hormon , total protein. albumin, NG ratio. total lipids, and triglyceride, while it was not effected on level of (GOT). Addition of sodium bicarbonate G3 increased (P<0.05) rumen pH and acetate production as compared to G1 .. Meanwhile, rumen pH, blood T 3. total protein and acetate concentration were lower as compared to G2 but not significant. Keywords: Sugar beet silage, lactating cows, rumen parameters, blood parameters, yeast culture, sodium bicarbonate.
