DRIED APPLE POMACE FOR FARM STOCK.

tainers and brought at once to the laboratory where moisture determina- 

 tions were made and composite samples analyzed. The grain was sampled 

 each time a new lot was mixed, and the samples preserved as in the case 

 of the hay. The apple pomace and dried beet pulp were sampled at regu- 

 lar intervals during the experiments. The milk was sampled for five 

 consecutive daj's three times during each half of each experiment, pre- 

 served with formalin, and total solids and fat determined in the usual 

 manner on the composite samples. 



The basal ration consisted of a uniform grain mixture plus sufficient 

 hay for the needs of each individual cow. The hay was of only fair qual- 

 ity, some of it being too coarse for good cow hay. With the exception of 

 the corn meal fed in the last experiment, all the concentrates fed were up 

 to the usual standards. The corn meal was unusually low in fat (1.69 per 

 cent), and although bought for meal from whole corn could not have 

 been such, probably having had the germs removed. A definite amount 

 of either apple pomace, beet pulp or corn meal was substituted for a like 

 amount of the basal grain ration, this amount varying with the different 

 individuals in the herd. The basal gram rations fed in the two experi- 

 ments are sho\\'Ti in the following table: — 



Table III. — Grain Mixtures Fed (Pounds). 



A definite amount of each mixture was given to each animal, — in the 

 first expermient from 6 to 10 pounds daily of I, with from 6 to 7 pounds 

 of either apple pomace or beet pulp ; in the second experiment from 5 to 

 7 pounds daily of II, with from 4 to 5 pounds of either apple pomace or 

 corn meal. 



Somewhat less of the basal grain ration was fed to each cow in the 

 second experiment than in the first, and the amount of hay per animal 

 increased, for the reason that it was not considered advisable to feed too 

 large an amount of grain in the corn meal half of the trial.
