178 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



but constant in composition. The same remarks apply to all by- 

 products of oatmeal mills, under whatever name sold. 



Brewers' and Distillers' Grains. Grisdale, of the Central 

 Experimental Farm, reports economical gains from " spirit 

 grains " when fed in combination with a meal ration. Gen- 

 erally speaking, these products are rather bulky and fibrous 

 for swine, unless used in a limited quantity as a supplement 

 to a grain ration, in much the same way as alfalfa hay or 

 roots. 



Sugar-Beet Pulp. In the wet state this product may be 

 regarded as similar in feeding value to roots, and may be em- 

 ployed in exactly the same way. The dried pulp is hardly a 

 satisfactory feed for swine. 



Beet-Sugar Molasses. Beet molasses is unpalatable and 

 generally unsatisfactory for swine. Bulletin 199 of the Cornell 

 Experiment Station reports apparent poisoning of hogs fed 

 beet molasses; and Utah (Bulletin 101) reports scouring, and 

 bad-flavored pork. 



Black-Strap Molasses. Texas Bulletin 131 reports a test 

 with ground corn compared with ground corn and black-strap 

 molasses. Three groups of hogs were used. Lot 1 was fed 

 equal weights of ground corn and molasses. Lot 2 was fed 

 two parts ground corn to one part of molasses by weight. Lot 3 

 was fed ground corn alone. There were eight hogs in each 

 lot, and the test lasted 91 days. The average weight of the 

 hogs at the commencement of the test was approximately 120 

 pounds each. Ground corn was valued at $28.20 per ton, and 

 molasses at $16.66 per ton. 



The average daily gains per hog and cost of gain were :
