In an analysis of Table XIV it is noted that only calcium and phos¬ 
phorus are not supplied in sufficient quantities. As stated previously 
these mixtures are fed with milk and sprouted oats in the proportion 
required as an average in these two feeding tests here given. It yet 
appears that it is necessary to add either bone meal, or bone and meat 
meal, to the mixture to bring these requirements up to the standard. 
Grit and oyster shell will supply the calcium, but not the phosphorus 
deficiency. 
During the year 1917 feed Mixture 7 was tried out at one of the 
Branch Experimental Farms. These birds were of the Single Comb 
Rhode Island Red. The hens were set and the chicks were brooded in 
the combination sitting and brooding coop*, the hen being confined 
to the coop and the chicks allowed to run at large. One-half the broods 
received milk in the mash and the other half no milk at all. Both lots 
secured worms, bugs and insects, as well as green feed, in ranging a short 
distance from their coop.
