98 REPORT oF THE DIRECTOR OF THE 
A 
Proximate Composition of Food Fed and also the Weight of 
Each Animal for Each Month of the Investigation. 
The following tables give the number of pounds of each food 
constituent consumed every month, as also the weight of each 
animal. 
Each table will show very considerable changes in the proxi- 
mate composition of the several rations, and the result of such 
changes may be studied with profit in connection with the tables 
following later, in which tables are given the milk yield and its 
composition for each month of the experiment. 
The tables 8 to 15 inclusive, are continuations from. the 
eleventh annual report of the first period of lactation. 
The first four, 8 to 11 inclusive, giving the food constituents of 
these four animals followed by four other tables, 12 to 15 inclu- 
Sive, giving the amount and composition of the milk yield. 
Tables 16 to 27 inclusive, are continuations from the eleventh 
annual report of the second period of lactation, presenting the 
same data as to food and milk yield. 
Tables 28 to 33 inclusive, give similar data for three animals in 
their jist period of lactation. 
Tables 34 to 45 inclusive, give similar results for six animals in 
their second period of lactation. 
Tables 46 to 65 inclusive, give the same data for ten animals in 
their third period of lactation. 
Tables 66 to 72 inclusive, give the food constituents in pounds 
consumed by each animal during each month of the third period 
of lactation, also pounds of milk yielded by each animal. 
Tables 73 to 77 inclusive, give.the per cent of each milk con- 
stituent for each cow during each month of the third period of 
lactation. 
Tables 78 to 82 inclusive, give the pounds of each milk con- 
stituent yielded by each cow in each month of the third period 
of lactation. 
Tables 83 to 89 inclusive, give the average food constituents in 
pounds consumed by each breed during each month of the third 
period of lactation, also the pounds of milk yielded on an average 
by each breed.
