as a supplement to corn or other carbonaceous feeds, and 

 for a limited period, usually not to exceed thirty or forty 

 days, excellent results may be secured from its use. Din- 

 widdle ^ expresses the conviction, with much experi- 

 mental evidence to support it, that cottonseed meal can 

 be fed indefinitely provided the amount does not exceed 

 ^ pound daily for a pig weighing 50 to 75 pounds, or 

 -^ pound daily for one weighing 75 to 100 pounds, or 

 ^ pound daily for an animal weighing 100 to 150 pounds. 

 Numerous experiments ^ have shown satisfactory and 

 profitable results from the limited use of cottonseed meal 

 for a short fattening period. On the other hand, other 

 investigators after successive and continuous efforts to 

 discover a practical and safe method of feeding it have 

 announced with emphasis their conviction that cotton- 

 seed or cottonseed meal could not be fed in any form, 

 for even a limited period, without running a serious risk 

 of loss. 



The following condensed statement by Henry and 

 Morrison ' may be accepted at this time as a reliable 

 summing-up of the numerous and extensive studies which 

 have been made of this feed by the experiment stations 

 of the country : 



"As now prepared, cottonseed meal is poisonous to 

 swine. All the various proposed ways for safely feeding 

 this meal have failed under careful and continued tests. 

 Pigs thrive at first on the meal, but usually in from 4 to 

 6 weeks some die — not all, as a rule, but so many that 

 all possible profits from the use of this feed are lost. A 

 few feeders continue to use the meal, experience enabling
