FEEDING BY-PRODUCTS 381 



experience, any economic advantages to be derived from 

 feeding this material will be secured by amounts well 

 under the danger limit, and that independent of its ef- 

 fects on health. The maximum safe allowance, if there 

 is any such, should be determined with certainty by ex- 

 periments more numerous and extensive than have so 

 far been carried out, and the figures deduced from our 

 own experiments are given with the knowledge that the 

 next man's work, or even our own under different con- 

 ditions, may necessitate their revision. For the benefit 

 of those who may wish to 'take the chances' on feed- 

 ing cottonseed meal or cottonseed to hogs continuously, 

 the following allowances appear to be well within the 

 danger limit : 



"Pigs under 50 pounds, M pound per day. 



"Pigs from 50 to 75 pounds, 1-3 pound per day. 



"Pigs from 75 to 100 pounds, 2-5 pound per day. 



"Pigs from 100 to 150 pounds, Yi pound per day. 



"If fed a full grain allowance, the dosage may be ob- 

 tained by properly proportioning the cottonseed meal to 

 the other components of the ration, namely : one to five, 

 six, seven, or eight, according to the stage of growth. 

 A meal ration containing cottonseed meal should also 

 contain at least an equal amount of wheat bran to supply 

 bulk. For the remainder, corn appears to be the only 

 choice." 



Experiments at the Texas station (Bulletin No. 78) 

 conducted with a view to determining a line of safety in 

 feeding cottonseed meal, resulted in the following recom- 

 mendations :
