The Value of Alfalfa and Certain of Its Fractions in the Nutrition of Breeding Ewes¹

Purdue University Agricultural Experiment Station^,3

Abstract

Conclusions:

1. Dehydrated oat grass was found to have a high nutritive value as a roughage for breeding ewes as judged by growth, maintenance, and milk production and for the production of thrifty, rapidly growing lambs.
   
2. It was found that 2.5 pounds of dehydrated alfalfa were required for good growth, maintenance, and milk production of breeding ewes when the basal ration was composed of yellow corn and corn silage.
   
3. Casein or cottonseed meal did not completely supplement the basal oat straw, corn, corn-silage ration for breeding ewes.
   
4. The water soluble fraction of alfalfa (pressed juice) was found to have definite nutritive value for breeding ewes.
   
5. The deficiencies of the basal ration of oat straw, corn and corn silage were found to be protein, vitamin A and factors contained in the water soluble fraction of alfalfa.
