FACILITY OF DIGESTION A FACTOR IN FEEDING PA 
In the above trials, calves fed whole milk with grain and 
roughage gained 1.86 pounds per day, and calves nursing their 
dams gained 1.77 pounds per day. Calves fed skim milk with 
grain and roughage, in the Kansas trials gained-1.58 pounds 
per day; New Hampshire 1.35 pounds per day; and SuSE 108 
pounds per day. 
Calves fed mixed hay tea with grain and roughage gained 
.86 pound per day ; with alfalfa hay tea .36 pound; and on calf 
meal in Pennsylvania’s trials .8 pound per day. The gains 
made by calves fed milk substitutes in the above trials can 
hardly be considered satisfactory when compared with the gains — 
of calves fed on skim milk.

In this trial each lot of calves received equal amounts of hay 
and bran. Lot 1 receiving skim milk made nearly twice the 
gains of Lot 2 fed calf meal. Exclusive of the hay and bran 
fed, the estimated dry matter required for one pound of gain 
was 1.09 with skim milk and 1.79 with calf meal. Henry* has 
shown that for pig feeding 475 pounds of skim milk contain- 
ing 37.9 pounds of digestible nutrients are equivalent to 100 
pounds of corn meal containing 78.9 pounds of digestible nu-
