Utilization of Ammoniated Industrial Products by Cattle

Oklahoma Agricultural Experiment Station²

Abstract

Feed lot trials conducted with steers fed fattening rations containing ammoniated cane molasses (ACM) and ammoniated furfural residue (AFR) indicated that the nitrogen of these products was not well utilized.The results were confirmed in digestion and nitrogen balance trials with fattening-type rations. Wintering trials with cattle gave evidence both for and against efficient utilization of the nitrogen in ACM fed as a supplement to dead winter range grass or wheat straw. Spraying the product on the dead range grass as a means of increasing forage intake gave poor results.

The digestibility of ACM (16% and 33% protein equivalent) was determined in trials in which both products were fed as supplements to prairie hay. The digestibility of crude protein (N x 6.2S) in the ACM products, which supplied 55% of the total ration nitrogen, was only 59%.

Feeding cattle a high test ammoniated molasses (32.2% protein equivalent) at a level of 2 lb. per day produced a peculiar stimulation within 5–6 days. For short periods cattle so stimulated reacted with violence and injured themselves by running into and attempting to climb fences in a manner of extreme excitement.
