VARIOUS GRAINS, MEALS, AND BY-PRODUCTS 177 
hogs weighed 99 pounds cach, and the other 131 pounds cach 
when the test commenced. At the start, one group of ten hogs 
was fed 6.5 pounds cottonseed meal and 16.5 pounds of eorn 
chop daily, and the other group of ten hogs was fed 7.5 pounds 
of cottonseed meal and 16.5 pounds of riec. 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 
tule. 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 Towa 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
