Ammoniated Cane Molasses and Similar Products in the Rations of Dairy Calves

Summary Ammoniated cane molasses, ammoniated inverted cane molasses and ammoniated condensed distillers' molasses solubles were fed to growing Holstein bull calves. The nitrogen from ammonia was fed as a replacement for the nitrogen of soybean oil meal and oats. It does not appear that nitrogen from ammonia can be used under the conditions studied in calves until they are nearly 12 wk. of age. In calves 12 to 16 wk. of age, gains of approximately 2.0lb. per day were obtained with rations containing these products. Similarly, it was found that the nitrogen of ammoniated products was as digestible as that of the nitrogen of soybean oil meal and oats in calves at 15 to 16 wk. of age. It appears that ammonia nitrogen may serve as a valuable source Of nitrogen for mature dairy cattle.
