952 Report oF THE First AssiIsTANT OF THE 
The results obtained in another trial with the same cows from 
October 1 to November 15, 1894, are given in table XIV. The 
cows had been in milk on the average a little over five months 
by October 1.. The data for the first period of this trial have 
just been reported in the preceding large table, but are here re- 
peated for comparison. In the second period alfalfa forage was 
fed in place of hay, and in the third period beets were fed. From 
October 16 to 31, inclusive, alfalfa forage was fed morning and 
noon and hay at night. The mixed grain, No. 43, consisted of 
five parts wheat bran, six parts corn meal,.and one part each of 
wheat middlings, linseed meal, O. P., cotton-seed meal and 
gluten feed. The grain represented 44.6 per cent. of the total 
cost of the ration and supplied 30.6 per cent. of the total digestible 
nutrients. The forage represented 32.0 percent. of the cost of 
the ration and supplied 47.9 per cent. of the nutrients. From 
November 1 to 15, inclusive, beets were fed morning and noon 
and hay at night. The mixed grain, No. 44, consisted of five 
parts wheat bran, one part ground oats, two parts corn meal, one 
part linseed meal, O. P., two parts “King” gluten meal, and one 
part cotton-seed meal. The grain represented 40.1 per cent. of 
the cost of the ration and supplied 33.1 per cent. of the total 
digestible nutrients. The beets represented 39.5 per cent. of the 
cost of the ration and supplied 43.6 per cent. of the total digestible 
nutrients. 
The nutritive ratio of the second ration was considerably nar- 
rower than that of the first. There was an increase in the 
amount of protein and fat and of total nutrients. The fuel value 
was higher and the cost of the ration considerably less. There 
was a pronounced increase in the milk yield and not much change | 
in the composition of the milk. The cost was much less for milk 
and fat than for the preceding period. In the third period the 
nutritive ratio was made wider, there was a decrease in the 
amount of digestible protein, fat, and of total nutrients -—- most 
noticeable in the fat. The cost of the ration was much higher 
and the fuel value was reduced to about that of the ration for the 
first period. There was a falling off in the milk yield from that 
of the second period, but very little more than the normal, 
accompanied by a slight decrease in the per cent. of fat. The 
milk and fat cost much more than in the second period.
