Examining this table, we note that there is a constant difference 
between the average weight of the cows the first and last four days 
of each period, in all but Period B which was starvation, showing 
about an equal gain; we note also that the average total weight is 
larger in Periods A and B under full feeding. These records in- 
dicate then, that under Period OC a maintenance ration was being 
fed, while in the Periods A and Da gaining ration. ; | 
We must hence come to the conclusion that the grains ure a 
valuable feeding material for maintenance, when fed with a small 
quantity of hay. . : 
For further confirmation we may refer to the first four days, on 
grains, as compared with the four preceding days on hay, where we 
find constant weight, with increased milk for the grains, the feed- 
ing ration being nearly equivalent; thus:

The first ration 26.8 lbs. of hay, the second rations 7.8 Ibs. of hay, : 
and 51.8 lbs. of brewers’ grains. 
During Period A 7 partial analyses of the milk were made, the 
average being 5.70 per cent of fat. During Period B, 16 partial 
analyses were made, the average being 6.91 per cent of fat, two of 
which analyses were of phenomenal richness, viz., 10.95 and 12.58 
per cent, for the morning and night’s milk from Meg. During 
Period C, 50 partial, analyses, and 5.91 the average fat. During 
Period D, 21 partial analyses, and 6.84 the average fat.

These average results do not indicate that the feeding of the 
brewers grains was detrimental to the quality of the milk. It may 
be well to supplement this table, however, with another, which shall
