The average of results obtained by Danish experimenters is a value 
of about GOO pounds of milk for 100 pounds of grain, but the greater 
amount of work of this nature in America has shown a higher value 
for skim milk. The average of nineteen trials in Wisconsin with 
proportions of milk ranging from 1 to pounds for each pound of 
grain fed, with hogs of all ages, was that 475 pounds of skim milk 
were equal to 100 pounds of meal. a In Utah b Linfield found the value 
of 100 pounds of milk in terms of grain (that is, the amount of grain 
replaced by 100 pounds of milk) to be 23.2 and 26.3 pounds, respect- 
ively, in two series of experiments. Grisdale c values milk at from 
one-fifth to one-sixth as much as mixed grain. In all experiments 
the large return where the proportion of milk to grain is small is par- 
ticularly noteworthy. Milk should never be given to pigs in unlimited 
amounts except while with the sow, or immediately after weaning, up 
to the weights of 75 or 100 pounds. At this earty age, much grain 
will disarrange the digestion and best results can be expected from a 
ration that is largely milk. 
Gram required for 100 pounds gain when feeding skim milk and 
grain as compared with grain alone and milk alone. — The following 
table is adapted from one compiled by Linfield d from the results of 
various stations for the purpose of showing the cost in grain of feed- 
ing rations of grain and skim milk, grain alone, and skim milk alone.
