INVESTIGATION IN ANIMAL NUTRITION 



more grain in the daily ration than steers can utilize. This is a source 

 of loss that should be prevented, and calls for a radical change in the 

 methods of feeding. 



By referring to Table XIV it will be seen that in the cost of pro- 

 duction of the yearlings, the grain amounts to $14.32, while the whole 

 milk item is $5.98. These are the two items in which there is danger 

 of giving more than is needed for normal growth. In the items of cost 

 for the second year the grain amounts to $39.92, and the roughage to 

 $14.19 under continuous stall-feeding, while the pasture lots used only 

 $23.89 for grain and $11.95 for roughage, showing that cost of pro- 

 duction was lowered when our grain feeding was the lightest. 



TABLE XXII 

 COST OF PRODUCTION, PASTURE LOTS OF GROUPS V AND VII 



Table XXII shows that the average feed-cost per steer of Groups 

 V and VII for the first year was $30.48, and for the second year after 

 returning from pasture $35.84, making the total feed-cost per steer 

 for the two years $66.32. The feed-cost for the yearlings of the two 

 groups was remarkably uniform. The additional cost for Group VII 

 the second year was caused by the steers making a daily gain of only 

 0.29 of a pound while in pasture, while Group V gained 0.8 of a pound 

 per day.

Table XXIII gives the average price for which the steers of 

 Groups V and VII were sold at the stock yards, the receipts per 

 steer, the cost of feeds, and return over cost of feed by each group. The 

 difference in price received per steer was due not so much to difference 

 in quality as to difference in price levels, that is, quotations were higher 

 when Group VII reached the market. The average price received was 

 $91.03, the cost of feed $66.32, and net income over cost of feed $24.71 

 per steer.
