pounds of gain, which is a very satisfactory showing. The 

 linseed meal was not so satisfactory as skim-milk, but gave 

 better results than other substitutes for skim-milk tested at the 

 same time. 



Cottonseed Meal. — This very concentrated feed possesses 

 some property which renders it fatal to hogs when used in con- 

 siderable quantities. A small allowance per day may be fed 

 without injurious results, but great care is necessary. The 

 Arkansas and Texas Experiment Stations have probably made 

 the most thorough investigations with cottonseed meal, and 

 their recommendations are worthy of note. 



Arkansas Bulletin 85 gives the following quantities of 



cottonseed meal per pig per day as being " well within the 



danger limit " : 



Pigs under 50 pounds, l^ pound per day. 

 Pigs from 50 to 75 pounds, y^ pound per day. 

 Pigs from 75 to 100 pounds, ? pound per day. 

 Pigs from 100 to 150 pounds, 1/2 pound per day. 



Texas Bulletin 78 makes the following recommendations: 



" 1. For animals on heavy feed, that not more than one-fourth the 

 weight of the grain ration consist of cottonseed meal. 2. That this feeding 

 continue not more than 50 days, or that the proportion of meal be reduced 

 if feeding is to be continued longer. 3. That tlie meal be mixed with 

 other feed and all soured together. 4. That as much green feed as possible 

 be supplied to the hogs. 5. That a close watch be kept, and the meal taken 

 from any animals not eating or not gaining well. 



" Feeders who have had experience with the meal will probably be 

 able to exceed these recommendations, whicli, however, allow the use of 

 enough meal to greatly improve a corn diet. One pound of cottonseed 

 meal to five of corn furnishes the nutrients in the most desirable propor- 

 tions for fattening, wliile one or two of corn are more nearly correct for 

 young, growing stock." 



Cottonseed Meal with Corn and Rice. — Bulletin 135 of 

 the Texas Experiment Station reports further trials of cotton- 

 seed meal with corn chop and rough red rice. One group of
