THE RATIONS FED. 
The feeding periods indicate the time through which each 
of the fodders was used. ‘The last nine days of this period 
were in each case taken to represent the test; five days being 
allowed after a change of feed before beginning the test. 
Each feeding period thus includes a preliminary period and a 
test period. The column headed ‘‘ Periods’’ simply gives the 
numerical order of the tests. Period 1 was a short prelim- 
inary period during which the yield of milk and butter-fat for 
the two groups was compared. 
During most of the tests seventy pounds of the green 
fodders were used, together with a very small amount of grain 
feed for each animal per day. In the corn fodder tests the 
amount was increased to eighty pounds. ‘This was found 
necessary in order to satisfy the wants of the animals. 
The green fodders were weighed as soon as practicable after 
cutting, a two-days’ supply usually being weighed at one time. 
In a few cases coarse butts of the fodders were not entirely 
eaten, and the nutrients in these were calculated as accurately - 
as possible and deducted from the rations as fed. ‘The grain 
ration consisted of two pounds of wheat bran and one pound 
of corn meal, daily: The grain feed was purposely made 
light, in order to obtain the maximum effect from the green 
fodders. ‘Table 14 gives the rations fed. It will be noticed 
that the cereal) fodders, rations 1, 3, 5; sete) in -aligee ee 
contained relatively small quantities of protein, and hence the 
nutritive ratios were wide; while the leguminous fodders 2, 
4, 6, etc., were in nearly. all. cases: quite: mich aneraeae 
and gave narrow nutritive ratios. ‘Iwo conditions in regard 
to the leguminous fodders tended to increase the protein in the. 
rations made up of such fodders, over those made up of the 
cereal fodders. ‘The leguminous fodders when harvested were 
richer in protein, and in most cases this protein was more 
thoroughly digested thah in case of the cereal fodders. 
RESULTS OF THE EXPERIMENT. 
The following table (14) gives the amounts of digestible 
nutrients fed in the different rations, as determined from the 
analyses of the fodders and the digestion factors obtained in 
the digestion experiments with sheep, together with the 
weights actually eaten.
