Abstract

Abstract 1. Urease activity was observed in all silage samples tested; but under average conditions of time, temperature, and moisture there was no practical destruction of urea when added to a dairy ration and placed over the silage in the manger. 2. No condition of unpalatability or digestive disorder in any commercial or test ration containing urea could be traced to the use of this ingredient. 3. The percentage of butterfat and protein in the test group and in the control group did not differ significantly. 4. Milk production during the first seven months of lactation was the same in the test group as in the control group.
