Du Zenggu (Shanxi Agricultural Univ., Taigu (China))
A feeding trial was conducted to evaluate the feeding values of wheat straw and corn stover treated with anhydrous ammonia (NH3) or urea. 42 heifers and steers weighing initially 135 kg were used in a random block design with 7 groups of cattle. The results showed that ammoniation significantly increased the nitrogen content of straws from 88 to 151% and decreased ingestion time per kg of the straw DM, live-weight gains (kg/day) were 0.66, 0.54, 0.57, 0.63, 0.56 and the control group of wheat straw and corn stover were 0.52 and 0.43
