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

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.
