110 HOW TO FEED YOUR HOGS 



speaking if a feed is mixed with considerable sand and earth, it is 

 relatively undesirable. 



Efficient Use of Cereals. It is well to know something about 

 the proper use of the cereal grains which are largely used in pork 

 production. If you take the grain or seed alone of wheat, or oats, 

 or corn, or barley, or rye, or kafir, or Milo maize, and attempt to 

 make young pigs grow satisfactorily on any one of these, we find 

 that when we feed them alone there is very little growth, and if the 

 pigs are young enough and of a very light weight when we start, 

 many of them may die. If protein alone is added it helps a little, 

 but not enough, and although we get a little growth, perhaps an in- 

 crease in live weight, yet the ration is manifestly very inadequate. 

 Add the Vitamine Fat Soluble A naturally mixed with butterf at, as 

 it actually is, and it helps very little. Add a mineral mixture alone 

 and it helps some, but the ration is inadequate. Add protein and 

 yellow butterf at (which always carries the Fat Soluble A) only, and 

 we still do not get desirable results. Add protein and mineral mix- 

 ture and we get somewhat better results than with protein alone or 

 the mineral mixture alone, but still unsatisfactory. Now if we add 

 a correct mineral mixture and the material found known as fat 

 soluble A (found in butterf at or alfalfa leaves or carrots) and 

 also a satisfactory protein we, generally speaking, get good growth 

 and development because we have supplied the grain's shortcom- 

 ings. In other words, all of these deficient materials must be pres- 

 ent at one and the same time in order to give good results. These 

 materials, of course, which the grains lack in sufficient quantity, 

 must be given with plenty of water, and in the proper proportion 

 if optimum results are* to be secured. 



If we take all of these above mentioned grains and mix them in 

 toto one with another in different and diverse proportions, we 

 still have an inadequate ration. It takes other feeds than these 

 grains to make up the ration, so that it is practical and efficient. 

 Add milk to any one of these, or to a mixture of any two or more, 

 and you get splendid results, generally speaking. Add alfalfa pas- 

 ture and the results are surprising. Add meatmeal tankage and 

 the results are splendid. That is because milk, and alfalfa pasture, 

 and meatmeal tankage contain all of the different deficient mate- 

 rials, and thus in practice the allowance of the deficiencies is sim- 

 plified, because we know that certain feeds are rich in just the nec- 

 essary nutritional materials that go to balance the grains. 



Commonly, the quality and quantity of the proteins of these or- 

 dinary grains are improved greatly by the leaves of plants, such as 

 those mentioned, or the plants of alfalfa, rape, red clover, young 

 tender bluegrass, sweet clover, white clover, Alsike clover, and 

 others. The meat by-products overcome these deficiencies, partic- 

 ularly when allowed in the form of meatmeal tankage ; bloodmeal is 

 also of importance. Fortunately the fat soluble A material can 

 also be secured in milk, and the leaves of plants, and to a con-
