 Agricultural Department. 



The economical and profitable growth and support of 

 animals require their food to contain one part of protein to 

 from five to seven parts of carbo hydrates. Within this 

 range, the proper ratio must be determined by the animal 

 fed and the object in feeding. The cow pea is distinctly a 

 protein feed, as may be seen from the following table of 

 Prof. W. A. Henry, in his book, " Feeds and Feeding."

The cow pea, then, belongs strictly to the protein class, 



with a narrow nutritive value in close relation to carbo-
