302 PRODUCTIVE FEEDING OF FARM ANIMALS 



bination of feeds fairly rich 1 in protein and mineral matter (N. R., 

 1: 7 or less), that will develop a body with normal bone structure, 

 muscles, and internal organs. As corn is deficient in both these 

 constituents, pigs require supplementary feeds of nitrogenous 

 character (skim milk, middlings, peas, tankage, dried blood, etc.) 

 for a normal growth, or, at least, an addition of wood ashes, 

 ground bone, or ground rock phosphate (floats), to build up a 

 strong frame. 



Where corn does not do well, other cereals may take its place 

 to advantage in the feeding of pigs ; wheat, barley, rye, kafir corn, 

 field peas, cowpeas, soybeans, etc., are all valuable swine feeds when 

 it is practicable to feed them, either in combination with Indian 

 corn or with each other. Barley occupies a similar place to the 

 farmers of California (and of northern Europe) as corn, does in

the corn-growing States, and has the advantage over corn in being 

 higher both in protein and ash. It will give best results with pigs 

 if? rolled or ground before feeding. Oats are not a satisfactory 

 swine feed on account of their high fiber content, except for breeding 

 stock and shoats that are not being fattened. In the case of these 

 animals they may be fed whole, scattered on the ground or on a 

 feeding floor, so as to give the animals exercise at the same time 

 (Fig. 78). 



Dairy products form a most important group of swine feeds 

 in dairy sections, and are used extensively as feeds supplementary
