Beet-Sugar Molasses. — Beet molassos is unpalatable and generally un- 

 satisfactory 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 Z 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 gain per hog and cost of gain were as follows :

In this test molasses proved lower in value than corn. It is pointed out in the 

 bulletin that molasses is poor in protein, and would likely have given better results 

 if fed with a feed richer in protein than corn. 



Tankage.— This by-product of the packing house is referred to under 

 supplementary feeds with corn, and also under substitutes for skim-milk. A good 

 brand of tankage contains over 50 per cent, of protein. It is valuable, therefore, 

 to use when the ration is deficient in protein. It costs a high price per ton, but it 

 is necessary to use only a small proportion in the feed, ten per cent, of the total 

 meal ration being sufficient in most cases. When corn constitutes the main ration, 

 or when skim-milk is not available for young pigs, the judicious use of a feed like 

 tankage increases the rate of gain and reduces the cost of each pound of gain. 



Weed Seeds. — Professor Henry conducted two trials at the Wisconsin 

 Experiment Station with pigeon-grass seed, cooked and uncooked, for swine. The 

 results are reported in " Feeds and Feeding." 



Lot 1 was fed two-thirds cooked pigeon-grass meal and one-third corn meal 

 uncooked. 



Lot 2 was fed corn meal only, uncooked. 



Lot 3 was fed one-third pigeon-grass meal and two-thirds corn meal, both 

 uncooked. 



Lot 1 made the largest gains and required the least feed for 100 pounds of 

 Justin, and lot 3 made the smallest gains and required the most feed for 100 pounds 

 of gain. 



Professor Henry .says : " It is evident that pigeon-grass seed when cooked is a 

 valuable feed for swine ... To be satisfactory for pig feeding the seed of 

 this grass should be ground and cooked." 



At the large elevators, weed seeds and small wheat accumulate in large 

 quantities, and this product can be used to good advantage in feeding swine when 

 judiciously mixed with other meal.
