The results of four experiments are described in which twenty-five pigs were fed on a ration containing half a pint of milk. Eighteen were fed on control rations, generally considered to be adequate, and of which in one series dried separated milk was a constitutent.

In every case the fresh milk produced an increase in live weight over the controls varying from 8 to 10 per cent. Less dry matter per lb. increase in live weight was consumed by the experimental pigs than by the controls.

The returns for half a pint of milk fed per pig daily expressed as pounds live weight gain per gallon of milk fed, were as follows:

The higher values in Exps. 2 and 4 may have been due to the fact that the pigs were individually fed but differed in that the milk was mixed with the food in Exp. 2 and fed separately in Exp. 4.
