Effect of adding yeast culture or sodium bicarbonate to Friesian cows diet containing fodder beet root silage on feed quality, milk production, feed conversion and body weight change

Abstract

Twenty one multiparous lactating Friesian cows were used to study the effect of adding yeast culture or sodium bicarbonate to daily diet of fodder beet root silage (FBRS) on nutrient digestibility, nutritive value milk production, feed intake, efficiency of feed conversion and live body weight change. Three days after calving the cows were assigned into three similar groups (7 cows each). Daily ration was composed of concentrate feed mixture (CFM), wheat straw (WS), and fodder beet root silage (FBRS) representing 30% of daily total TDN requirements given to group 1 (G1 as control). Rations of second (G2) and third (G3) groups were supplemented with 15.0 gm./day/head yeast culture or 150.0 gm/day/ head sodium bicarbonate, respectively. Results indicated that cows received yeast culture in their daily diet had higher (p<0.05) milk production, fat, protein and total solids. Digestion coefficients, feeding values, feed conversion (TDN/Kg FCM) and body weight change during the first 12 weeks post- calving were also better (P<0.05) compared to control group. Cows in G3produced higher milk (P<0.05), meanwhile, there was insignificant increase in fat, protein, lactose and total solids. Treatment of NaHCO3 had neither effect on nutrient digestibility, nutritive value, feed conversion nor body weight change than control group. Keywords: Dairy cows, yeast, sodium bicarbonate, digestibility, milk, body weight.
