Summary of Coefficients showing Effect of High-grade Wheat Gluten Flour 

 wpon Digestibility of Hay — Continued. 



1 In case of hay alone, period 2. 



This experiment was with a new lot of hay, testing in dry matter 6.59 

 per cent, ash, 7.59 per cent, protein, 32.67 per cent, fiber, 50.29 per cent, 

 extract matter and 2.86 per cent, fat, and having a nutritive .ratio of 

 about 1:17, being very wide. The wheat gluten was the same as the lot 

 previously fed, and the combination of 700 grams hay and 40 grams 

 wheat gluten had a nutritive ratio of 1:5.7. In other words, the addition 

 of 40 grams of gluten to 700 grams of hay produced a much narrower 

 ration than if the hay had been fed by itself. A study of the coefficients 

 shows no particular improvement in the digestibility of the hay as a 

 result of adding the gluten, although such an improvement was antici- 

 pated. 



Applying the coefficients secured for the hay when fed by itself to the 

 same hay fed in combination with wheat gluten, and subtracting the 

 result from the total amount of hay plus gluten digested, we have 38.58 

 grams of gluten digested as against 37.18 grams fed, showing the gluten 

 to have been completely digested.

 upon Digestibility of Hay — Concluded.
