immediate; the pigs began to gain Inweighl at once, and those receiv- 
ing the greater amount of cotton-seed meal made the Larger gains. 
No other feed was given. The first pig died on the forty-fifth day of 
the experiment, the second on the forty-eighth day, the third on the 
fifty-third day, and the fourth on the fifty-sixth day from the begin- 
ning of the cotton-seed meal feeding. Two pigs were left in each lot; 
they were placed on green oats and then thrived nicely. 
A later bullet in" from the Kansas Station mentions a lot of pigs 
that had done poorly in another experiment; 1 hey were fed cotton- 
seed meal, and were "ready for market, well finished, in twenty-two 
days." At the Kansas Station cotton-seed meal is very highly regarded 
to put pigs in high condition, if fed for a short time in small quanti- 
ties. The beginning ration is one-fourth pound cotton-seed meal to 
each 1,000 pounds live weight per day, which is increased in ten days 
to make the amount 3 pounds per 1,000 pounds live weight. 6 The 
meal is mixed with the rest of the grain. 
The Kansas and Iow T a results show that a cotton-seed meal ration is 
valuable if the cotton-seed meal is used in a moderate amount and 
for a limited time. The proportions of cotton-seed meal used in the 
Iowa test were about one-eighteenth and one-ninth of the total grain 
rations at the start and about one-tenth and one-fifth at the close. Up 
to the time the pigs began to die the gains of those on the heavier 
cotton-seed meal ration were the larger and more economical (1.4 
pounds average daily gain and 343 pounds meal and 250 pounds milk 
per 100 pounds gain). The lighter ration was about equal in results 
to one of corn-and-cob meal, gluten meal, and buttermilk, that stood 
second to the heavy cotton-seed meal ration. The two lots returned 
in pounds of gain per 100 pounds of dry matter in the feed (before 
deaths began) 31.1 pounds and 26.4 pounds, respectively, for the pigs 
on the heavy and the light rations. In the Kansas tests the gains 
before deaths commenced were also very economical; they varied in 
cost from considerably less than 300 pounds grain per 100 pounds 
gain in the case of the pigs that had been previously on the single- 
grain rations to 350 pounds grain per 100 pounds gain in the case of 
the sows. 
Pigs following steers on cotton-seed meal. — Evidence of the danger- 
ous properties of cotton-seed meal for pigs, when they are following 
steers whose ration is made up wholly or in part of cotton-seed meal, 
is conflicting. In the Iowa test c a lot of 3 pigs followed steers for 
seventeen weeks that were receiving from 4 to 7 pounds of cotton- 
seed meal daily. They had very little feed except what they picked 
up behind the steers, yet there were no noticeable injurious effects.
