2,954.75 lbs. of milk containing 3.77 per cent of fat. On the cotton-seed meal 

 ration they gained 120 lbs. in weight and produced 2,913.5 lbs. of milk contain- 

 ing 3.72 per cent of fat. There was no difference in churnability of the milk 

 or in flavor and quantity of the butter in favor of either of the rations, except 

 that the butter made during the feeding of cotton-seed meal was the harder 

 and of a better color. 



In a test comparing decorticated peanut cake with decorticated cottonseed 

 cake the cows were fed a basal ration of mangels, hay, bran, and dried yeast, 

 and in addition either 4 lbs. of peanut cake or 4 lbs. of cottonseed cake. On 

 peanut cake the cows lost 51 lbs. in weight and produced 3,504.25 lbs. of milk 

 containing 3.86 per cent of fat; and on cottonseed cake they gained 111 lbs. 

 in weight and produced 3,437.25 lbs. of milk containing 3.97 per cent of fat. 

 There was no difference in quality or flavor of the butter from either of the 

 rations, except that the butter churned during the peanut ration period was 

 the softer. 



Analyses of each of the concentrates compared in the.se tests are given.
