Effect of adding yeast culture or sodium bicarbonate to lactating Friesian cows diet containing fodder beet root silage on their reproductive performance

Abstract

Twenty one lactating Friesian cows were used to study the effect of adding yeast culture or sodium bicarbonate to a ration containing fodder beet root silage (FBRS) on reproductive performance. The interval from parturition to complete uterine involution (PPUI), first detected estrus (PPEI), first services per conception (NS/C) and days open (DO) were determined. Three days after calving cows were assigned randomly into three equal groups (n=7). Cows of the first group (GL, control ) fed ration contained FBRS represented 30% of the required TDN, concentrate mixture 70% of the require TDN and wheat straw. Ration offered to the second (G2) and third (G3) groups were similar to G1 except that it was supplemented with 15 gm/day/head yeast culture and 150gm/day/head sodium bicarbonate for G2 and G3. Respectively. Results indicated that supplementing ration with yeast culture (G2) improved (P<0.05) PPUI, PPOI.DO, NS/C and CR% as compared to the other groups. However, there were no effect on PPEI and PPSI among the studies groups. Treatment with sodium bicarbonate (G3) improved PPUI and PPOI as compared to untreated cows (G1). Keywards : yeast, sodium bicarbonate, dairy cows, reproductive performance.
