Feedi and Feeding. 



It will be seen tliat the cheapest returns were obtained from 

 feeding boiled cotton seed, Bermuda hay and silage; next in 

 economy came raw cotton seed, while cotton-seed meal, at the 

 price charged, stood third in cost. Cotton seed was found to be 

 much cheaper than corn meal. (216-17, 723) 



645. Cotton-seed meal compared with bran. — At the Pennsyl- 

 vania Station, ' Hunt obtained about one-fifth more milk when the 

 cows were fed cotton-seed meal in place of bran, the cotton-seed 

 meal (sis pounds) constituting about three-fifths of the concen- 

 trates and about one- fourth of the total feed eaten. The percent- 

 ages of fat in the milk were not influenced by changes in feed. 



646. Linseed meal versus cotton-seed meal. — At the Pennsyl- 

 vania Station, ' Waters and Hess compared linseed meal with cot- 

 ton-seed meal. Nine cows were used in this trial, the ration in 

 one period consisting of cotton-seed meal, chopped wheat and corn 

 stover; later, the cows were fed the same ration, except that lin- 

 seed meal (old process) was substituted for the cotton-seed meal. 

 The results of the trial were as follows:
