BRIEF DESCRIPTION OF CALF FEEDING EXPERIMENT 



RATIONS USED. Three rations were used in this experiment 

 as indicated below. 



LOT I. RATION I (Skim milk) 



Consisting of whole milk, skim milk, ground corn and oats as 

 a dry mash, alfalfa hay and corn silage. 



LOT II RATION II (Home-mixed calf meal) 

 Consisting of whole milk, home-mixed calf meal (containing 

 hominy feed, linseed meal, red dog flour and dried blood, equal parts 

 by weight), ground corn and oats as a dry mash, alfalfa hay and 

 corn silage. 



LOT III. RATION III (Blatchford's Calf Meal) 



Consisting of whole milk, Blatchford's Calf Meal, ground corn 

 and oats as a dry mash, alfalfa hay and corn silage. 



The above rations were fed for a period of one hundred eighty- 

 two days to three lots of ten calves each. 1 Most of the calves used 

 in this experiment were pure-bred animals from cows belonging to 

 the Experiment Station dairy herd.

HISTORY OF CALVES UNDER EXPERIMENT 



The record of the performance of each individual calf was 

 kept separately, both in regard to feeds consumed and the variation 

 in live weight. A daily record was made of the feeds fed and the 

 body weight was determined at the end of each seven days. At the 

 conclusion of each thirty days, the calves were photographed under 

 standard conditions and in a way that would show the physical 

 condition of the calf as well as the variation in size. These photo- 

 graphs- represented six thirty-day periods during the first six months 

 of the calf's life and are presented together with a tabulated aver- 

 age daily summary of the feeds consumed, composition of ration, 

 cost of ration, and variations in live weight.
