70 STORRS AGRICULTURAL EXPERIMENT STATION. 
first ration fed was found to be quite a narrow one, containing 
large quantities of protein—z2.1 pounds daily for animals of 
775 pounds, live weight. It was thought that the ration 
might be cheapened, which was done by substituting cotton 
seed meal for a part of the gluten. Although the second 
ration was fully as rich in protein as the first, and had as 
narrow a nutritive ratio, the animals failed to produce as much 
milk or butter on the second ration. ‘The proportion of coarse 
fodders was considerably increased in the second ration, and 
this may account in part for the smaller milk and fat yields. 
It is interesting to note that the percentage of fat in the second 
ration was larger for every cow than in the first.
