Effect of feeding of urea ammoniated soybean straw on blood biochemical parameters of lactating cows

Feeding of untreated soybean straw (T 2 ) and 2 per cent urea treated soybean straw (T 3 ) was evaluated on the performance of lactating cows in reference to conventional jowar straw diet (T 1 ). It was found within 120 days trial that, the Hb levels showed a increase from the initial level of 9.83 to 9.96, 9.76 to 10.08 and 9.86 to 10.80 g/dl/cow, blood glucose levels increased from 48.68 to 48.89, 45.89 to 53.36 and 45.16 to 56.24 mg/dl in T 1 , T 2 and T 3 groups, respectively The STP levels increase from initial content was 5.89 to 6.05, 5.76 to 6.38 and 5.70 to 6.58 g/dl, Significantly more BUN (17.82 mg/dl) was noticed in cows offered with T 3 followed by T 2 (13.85 mg/dl) and T 2 (16.66 mg/dl) while blood urea pooled means were noticed as 29.65, 38.13 and 35.67 mg/dl in cows offered T 1 , T 2 and T 3 groups, respectively The pooled means of STL were 278.15, 298.22 and 302.30 mg/d, the pooled means of STC content were 69.18, 68.64 and 77.06mg/dl and the serum triglyceride content of blood increased were 16.72, 16.79 and 17.57mg/dl, in cows offered T 1 , T 2 and T 3 groups, respectively. The results do suggest that 2 per cent urea treated SBS can find a place in the ration of lactating cows without any adverse effect on health of cows.
