Table XII shows the results obtained in a feeding trial during 
July and August, 1894. Eight cows were used in this trial of the 
average age July 1 of 5.2 years. At that date they had been in 
milk on the average 37 months. From July 1 to 31 oat-and- 
pea forage was fed morning and noon, hay at night and a mixed 
grain, No. 39, consisting of five parts wheat bran, one part ground 
oats, five parts corn meal, one part wheat middlings. The grain 
represented 41.7 per cent. of the cost of the ration and supplied 
21.0 per cent. of the digestible nutrients. The forage represented 
37.0 per cent. of the total cost of the ration and supplied 65.0 per 
cent. of the total digestible nutrients. Irom August 1, to 
9, Inclusive, alfalfa forage was fed three times daily and 
mixed grain twice. The mixed grain, No. 40, was composed of 
four parts wheat bran, one part ground oats, eight parts corn 
meal, one part wheat middlings and one part “ King” gluten meal. 
The grain cost 45.2 per cent. of the cost of the ration, the forage 
representing 54.8 per cent. The grain supplied 21.6 per cent. of 
the total digestible nutrients, the forage supplying 78.4 per cent 
From August 10 to 31, inclusive, corn silage was fed three 
times daily and mixed grain twice. The mixed grain, No. 41, 
was composed of six parts wheat bran, one part ground oats, two 
parts “ King” gluten meal, and one part cotton-seed meal. The 
grain represented 41.2 per cent. of the total cost of the ration and 
the silage 58.8 per cent. The grain supplied 25.9 per cent. of the 
total digestible nutrients and the silage 74.1 per cent. Although 
the grain was changed for the second period and alfalfa forage 
took the place of oat-and-pea forage and hay — the fodd contain- 
ing more moisture — there was almost no change in the propor- 
tion or amounts of the different constituents of the food. The 
nutritive ratio was the same and the fuel values nearly alike. 
The cost of the second ration was less. There was very little 
decrease in the milk yield, but a slight falling off in the per cent. 
of fat. The cost of milk was about the same and the cost of fat 
somewhat higher. 
In the third period when corn silage was fed instead of alfalfa 
forage, the cost of the ration was increased, and the nutritive 
ratio was made considerably wider. There was an increase in 
the amount of fat and a decrease in the protein; the total nutri- 
tive substance was less and the fuel value lower. There was a
