Effect of feeding sodium bicarbonate to cows fed on high concentrate ration



Effect of feeding sodium bicarbonate to cows fed on high concentrate ration



Pakistan Journal of Agricultural Research 9(4): 580-584



Twenty Jersey cows of similar weight, age and stage of lactation were randomly divided into two groups of 10 each. Prior to initiation of the experiment both groups were fed on a concentrate ration containing 14% crude protein (CP) and 67% total digestible nutrients (TDN). Green fodder, comprising 50% berseem and 50% mustard, was offered. The concentrate (17.40% CP, 75% TDN) was fed at 8 kg and green fodder was offered at 30 kg per head per day. One group obtained in the concentrate ration, 1.5% sodium bicarbonate (NaHCO3) as a buffer. After 30 days the cows fed NaHCO3 yielded, on an average, 0.5 litres of more milk than control (P < 0.05). The values of fat corrected milk (FCM) were higher for cows fed on concentrate ration having 1.5% NaHCO3 (18.69 and 19.57 l/head/day) as compared with cows fed on control ration (17.64 and 18.18 l/head/day) after 15th and 30th days of experimentation (P < 0.05). Cows fed on concentrate ration containing 1.5% NaHCO3 exhibited slightly higher feed intake. Between group differences in butterfat and in total solids of milk were statistically significant in favour of cows supplemented with NaHCO3.
