Because of the heavy character of the gluten meal it was 

 deemed advisable that not over one-half of the concentrates in 

 the ration consist of this material. The roughage was of equal 

 parts silage and hay, by weight. 



There was a gain of 10.4 per cent of milk and 13.2 per cent, 

 of fat by substituting gluten meal for half the corn meal and 

 bran of the ration. 



The results of this trial and that with maize feed substantiate 

 the claim of high nutritive value for these by-products of the 

 glucose and starch factories. (161-4) 



637. Gluten meal compared with cotton-seed meal. — At the 

 Maine Station, i Bartlett fed six cows, averaging 900 pounds each, 

 for two months on rations containing cotton-seed meal and gluten 

 meal, with the results shown in the table: 



Bartlett concludes: ''The foregoing data indicate that gluten 

 meal is fully equal to cotton -seod meal when fed in sufficient 

 quantity to make the amount of digestible nutrients equal in each 

 ration. It is not equal to cotton-seed meal pound for pound as a 

 source of protein, as it contains, on an average, about one-quarter 

 less of that nutrient. It makes a very good quality of butter, but 

 slightly softer than that made from cotton-seed meal when fed in 

 the quantity used in this experiment." (161-4, 210-12, 216-17) 



638. Wheat meal compared with corn meal. — At the Maine Sta- 

 tion, 2 Bartlett also compared wheat meal with corn meal, six cows
