BALANCED RATIONS. 
The proportion of grain and mash, the cost of 100 pounds of the 
ration, and the nutritive ratio are given in Table 11. The cost of 
100 pounds of feed from the different rations varies somewhat 
according to the proportion of mash and grain and to the nature of 
the ration, although this difference is not large except in Pen 9, in 
which the feed is from 10 to 20 cents per 100 pounds cheaper than in 
the other pens. The nutritive ratio and the cost of the ration in 
the cottonseed pens (Nos. 10, 11, 15, and 16) was quite low, but the 
cost of production was very high. The cost of the ration in Pen 9 
is the lowest because it does not contain beef scrap, but this ration 
produced eggs at the highest cost per dozen during the pullet year
