GAINS DURING SUMMER. 
In the spring of each year as soon as the grass was good enough, 
which was usually about May 1, the steers from all the lots were 
turned into the same pasture on grass with no additional feed. 
Weights were taken every 28 days, just as during the winter. Thus 
the effect of the different rations upon the summer grazing of the 
different lots could be studied. 
Table 6 shows the weights at the beginning of the grazing period, 
the weights at the end of the grazing period, and the total and 
average gains per steer for the summer period.
