in size. Water was supplied in these lots at all times and salt was 

 constantly available. The calves were fed twice a day. 



The feed, both concentrates and roughages, was weighed at each 

 feeding, and accurate records of it kept. The calves were weighed 

 at the beginning and at the end of the feeding period, the weights 

 being taken three days in succession and the average taken as their 

 initial and final weights. They were also weighed once every 28 

 days, in the morning after feeding. Neck straps with numbers on 

 them were used so that the identification of each individual could be 

 accurately kept. 



In the spring of each year, as soon as the grass was good enough, 

 which was usually about April 22, the calves from all the lots were 

 turned into the same pasture with no additional feed. Weights were 

 taken once every 28 days, just as during the winter. Thus the effects

 could be studied.

QUANTITY OF FEED CONSUMED. 



In considering the quantity of feed consumed it should be kept in 

 mind that the calves were not getting fattening rations, but only 

 enough to keep them in thrifty growing condition. Table 3 shows 

 the total amount of different feeds eaten in the various lots and the 

 average daily ration per calf in each lot during each of the three 

 winters.
