VARIOUS GRAINS, MEALS, AND BY-PRODUCTS 177 



hogs weighed 99 pounds each, and the other 131 pounds each 

 when the test commenced. At the start, one group of ten hogs 

 was fed 6.5 pounds cottonseed meal and 16.5 pounds of corn 

 chop daily, and the other group of ten hogs was fed 7.5 pounds 

 of cottonseed meal and 16.5 pounds of rice. Towards the close 

 of the experiment, lot 1 was fed 12.5 pounds of cottonseed 

 meal and 78 pounds of corn chop, and lot 2 was fed 15 pounds 

 of cottonseed meal and 70 pounds of rice daily. At first the feed 

 was given fresh, but a month later all feed was fermented. 



The hogs made satisfactory gains, and no evil effect was 

 observed at any time. The author states that the Station has 

 hopes that further experience will remove any need for uneasiness 

 when feeding cottonseed meal (see Caution, pp. 162 and 163). 



Hogs following cattle which are fed a considerable amount 

 of cottonseed meal in their ration do not appear to be in- 

 juriously affected, though there seem to be exceptions to this 

 rule. Just how much cottonseed meal can be fed to cattle with- 

 out injury to the hogs following them, does not appear to be 

 definitely settled. Prof. E. T. Robbins, of the Iowa Experi- 

 ment Station, writing to the Breeder s Gazette, reviews the ex- 

 perience of cattle feeders in connection with this problem, and 

 states : " Even when fed to steers under the best of circum- 

 stances it may possibly, in the opinion of some feeders, be 

 associated with an unaccountable mortality among the hogs." 

 In summing up, he says : " The general consensus of opinion 

 is to the effect that if fed in no larger amounts than 2 to 3 

 pounds daily per steer, with as many hogs as steers in the 

 feed lot, all danger to the hogs is practically eliminated." 



Oat Feed. This by-product of the oatmeal mill sometimes 

 has a considerable feeding value, but, owing to the fact that 

 it often contains a large proportion of oat hulls, it is not a 

 very satisfactory feed to buy for swine. Experiments with 



oat feed are not satisfactory, because the product is anything
