milk experiments would contain the following amounts of 



digestible organic nutrients 



One ton hay, 



One ton cotton-seed feed, 



1,007.3 

 964.4 



One would therefore suppose that a ton of cotton-seed feed 

 would have nearly the same feeding value as a like quantity 

 of hay. There might be one exception to the above state- 

 ment, in that it is possible that rather more energy would 

 be required to digest the cotton-seed feed than the hay. 



C. Milk Experiments with Cotton-seed Feed. 

 Experiment I. 

 This experiment was conducted during April and May, 

 1896. The animals, six in number, were evenly divided 

 into two lots. In order to counteract the natural milk 

 shrinkage, three of the animals in the first half of the exper- 

 iment were fed the cotton-seed feed ration, while the other 

 three were having the hay ration. In the second half this 

 order was reversed. Each half of the experiment lasted 

 twenty-one days, and from seven to ten days were allowed 

 between the halves. 



History of the Cows. 



Five of the above cows had been in two previous experi- 

 ments since October, 1895.
