158 ~ HOW TO FEED YOUR HOGS 



alfalfa are checked against corn and tankage and alfalfa. At 

 ordinary prices, oilmeal is a very good "buy," providing of course 

 that it is used wisely in combination with such supplements as 

 milk, tankage, the good leguminous pastures, and similar feeds. 



Bloodmeal. This is a packing house dry product, being the 

 dry blood from mixed animal sources, mostly ox. It runs 85 percent 

 in protein higher in protein than any of our supplements, but 

 it is too low in mineral matter. The addition of steamed bonemeal 

 to a bloodmeal ration when fed with corn or similar basal feeds 

 helps, as some of our tests show. We believe that bloodmeal fed 

 on alfalfa or rape pasture in conjunction with milk will give very 

 good results, and we would encourage its partial use in these 

 respects, particularly when the prices of tankage and bloodmeal 

 are so close together, as for instance when tankage sells at $100 

 a ton and bloodmeal at $125. As a lone supplement to corn or 

 similar feeds, bloodmeal does not work nearly as well as meatmeal 

 tankage, but fed in conjunction with meatmeal tankage it works 

 splendidly. Packers are therefore putting out tankages containing 

 considerable blood in their make-up. Some day we are going to 

 know how to use. bloodmeal to a better advantage than we do now. 

 The addition of bloodmeal to tankage in the packing houses is to be 

 encouraged, so long as they keep the mixture on an efficient basis, 

 inasmuch as it will produce a larger output for the general swine 

 feeding industry. So far the supply of meatmeal tankage has been 

 too low for the best interests of all concerned. Bloodmeal is good 

 for scours. 



The more meat and milk products we can add to the swine 

 ration within reasonable limits, and at certain prices, the better off 

 will our industry be, particularly when it is on the present corn and 

 other similar grain "balance basis" and where the natural grain 

 feeds of the farm are fed in large quantities. 



Soy Bean Meal. This is similar to oil meal. It should not be 

 used as a lone supplement to feed to hogs which are quite immature. 

 Bean proteins do not balance corn proteins satisfactorily, unless they 

 are helped out apparently with such feeds as a little milk or a little 

 alfalfa pasture or a little tankage or some similar feed. Rape is fine. 

 More and more soy beans are going to be grown in the future 

 because they are a profitable crop, particularly where they grow 

 well and yield 25 or more bushels to the acre. They make a good 

 concentrated swine feed as they do a good cattle feed. In cattle 

 feeding they have been found to be equal to about the value of cot- 

 ton seed meal. Our advice to those men who can grow soy beans 

 so they yield upwards of 25 bushels to the acre is to study the plant, 

 and figure on introducing it into their farm systems. But we 

 cannot pass to the next feed without re-emphasizing that the soy 

 bean has many serious limitations as does oilmeal, but that fed 

 in its right place it is a valuable adjunct as a supplement in swine 

 feeding.
