Food Adapted to Pigs 365 



of grain, but when the milk and grain were as 4 to 

 1, 100 Ibs. of milk only replaced 24 Ibs. of grain. 



Doubtless with pigs in the earliest stages of growth 

 after weaning, the proportion of milk to grain may 

 well be larger than in the more mature periods, and 

 in any case the ratio will naturally depend somewhat 

 on the relative supply of the milk and grains. 



In the absence of dairy wastes, meat meal, dried 

 blood and fish scraps may be used to supplement the 

 grain products or a mixture of the more nitrogenous 

 feeding stuffs with corn and barley will be found greatly 

 superior to the corn or barley alone. Milk is more 

 efficient with young pigs than the grain feeds rich in 

 protein, but in the maturer periods the digestible mat- 

 ter of certain of the latter seems to have a value not 

 greatly, if any, below that of skim -milk solids. 



The protein feeds adapted to pigs are gluten meal, 

 gluten feed, buckwheat middlings, brewer's wastes, 

 peas and middlings. The oil meals, excepting in small 

 quantities, affect the health of swine unfavorably, and 

 wheat bran is inferior to middlings. 



Of the carbohydrate foods, oats, barley, wheat, 

 rice products, and especially corn, are all useful. 

 Although the excessive corn feeding of swine is to be 

 deplored, this grain is second in value to no other 

 in the pig's ration, and only needs to be reinforced 

 with more nitrogenous feeds in order to find a safe 

 and profitable use. In the later stages of growth or 

 fattening it may well form the major part of the 

 ration. Probably no combination has been found 

 more satisfactory for all around use than skim -milk,
