total gains made by the calves in Lot I, it is evident that there was 

 considerable difference between individual calves 'so far as the ef- 

 ficiency with which they used the feeds was concerned. The calf 

 that cost $10.32 for feed during the first six months of its life was 

 the smallest calf at birth and made a daily gain of slightly over i.o 

 pound. The calf ranking next to the one just mentioned, in feed 

 cost, was the heaviest calf at birth and made the largest daily gains. 

 The most expensive calf cost $15.01 for feed during the experiment 

 and ranks next to the heaviest in birth weight. 



The average cost of feed during the course of the experiment 

 was $12.63 per head for all calves in Lot I. The uniformity in 

 cost is especially noticeable. The average cost of six of the ten 

 calves varied less than 50 cents per head from that of the average 

 for the lot and the average cost of eight of the ten calves varied less 

 than 85 cents per head from the average for this lot. With two 

 exceptions, the individual cost of the calves in this lot varied less 

 than 40 cents per head from that of the average cost. The most 

 expensive feeding period was during the second week of the test, due 

 to the large consumption of whole milk. After the third week, the 

 average daily cost gradually increased from 3.4 cents per head to 

 <S.C) cents per head at the end of the experiment.
