Ammoniated Sugar Beet Pulp as a New Nitrogenous Feed for Ruminants

The Quaker Oats Company Research Laboratories

ABSTRACT

1. An experiment on the ability of Holstein calves to grow on ammoniated plain sugar beet pulp has been conducted.
   
2. The experiments indicate that the animals can use such nitrogen sources for their nutritional needs. They grew at the rate of about 1.6 pounds per day as compared with 1.96 pounds for one animal on toasted soybean meal.
   
3. Animals fed a diet in which starch was substituted for molasses grew as well as those on rations containing the molasses. This indicated that the soluble carbohydrate did not further the use of the nitrogen by the microorganisms in the digestive tract any better than starch.
   
4. The animals grew just as well on rations 12.42 per cent protein as those on 17.02 per cent protein (N x 6.25).
   
5. No diuresis of any of the animals occurred.
   
6. The blood was analyzed for fifteen different constituents three times during the experiment and found to be normal.
   
7. The animals and their internal organs passed federal inspection at the Swift and Company yards. The soybean-meal animal had a diffuse cirrhotic liver. This is not evidence that the liver condition was connected with the soybean meal. Macroscopic examinations of the kidneys showed them to be normal.
   
8. Rib and liver cuts as well as one kidney from each animal were analyzed and found to be normal in protein. The color and flavor of the meat was normal.
   
9. Further work is indicated.
