MISSOURI AGRICULTURAL REPORT. 



Station fed two lots on tankage, one received ten parts of corn meal 

 to one of tankage, the other five parts of corn meal to one of tankage, 

 the object being to see how much tankage they should feed for tlie 

 greatest profit. This tankage, by the way, is a refuse product from 

 the packing house. The meat scraps that cannot be used in sausage 

 or handled otherwise for human consumption, arc thrown into the 

 rendering vat. Here it is steamed under about 40 pounds of pressure 

 until all of the fat has come to the top as oil ; after the removal of the 

 oil the remainder, which consists of the lean meat and bone scraps, 

 is dried, ground, sacked and sold for hog feed. At the time that these 

 experiments were conducted it cost $30 per ton. The better grade 

 only should be used, as the higher grade is a cheaper feed than the 

 lower one. If it can be had at $30 a ton, it is a cheap feed. The daily 

 gains in these two lots were 1.17 and 1.24 respectively; the grain 

 per hundred weight of pork very nearly the same. The cost was 

 greater where the larger proportion of taiikage was fed. They made 

 pork more cheaply by feeding ten parts corn meal to one of tankage 

 than five parts corn meal to one of tankage. 



The Iowa Station fed another lot of hogs on this five to one ration 

 and it was the less profitable of the two. The hogs made a tremendous 

 gain, 2. 57 pounds a day. The grain per hundred weight gain was very 

 low, 381 pounds, and considering the fact that these hogs had been 

 grown to a weight of 200 pounds before the experiment began, that is 

 a very low requirement. Tlie cost of 100 pounds of gain was $2.97. 

 But they made such a splendid showing for corn meal alone that they 

 got no added profit from the use of the tankage. If these had been 

 younger hogs, the corn meal would not have done nearly so well in 

 proportion. They could not have grown on corn meal alone nearly 

 as well as on corn and tankage.
