poisoning from cotton seed meal is obtained if the 

 nogs are allowed plenty of green forage or are kept 

 on pasture and, particularly, if wheat bran is 

 mixed with the grain. Within these safe propor- 

 tions the long continued use of cotton seed meal 

 does not give rise to any bad effects. According to 

 other calculations of safe rations of cotton seed 

 meal it may not be used in amounts greater than 

 one-fourth pound to each one hundred pounds of 

 live weight. As a result of experience had with 

 cotton seed meal in Oklahoma, it is recommended 

 that this grain be not added to a greater extent 

 than one-fifth as compared with other grains and 

 that it be fed in alternate periods of two to three 

 weeks. According to the experience which has 

 been had in Arkansas, it is not necessary to inter- 

 rupt the ration of cotton seed meal provided it is 

 made low enough. In Kentucky it was found com- 

 paratively safe to use cotton seed meal in rations of 

 one-half pound per day for each pig, particularly 

 during the finishing period. In Washington the 

 amount of cotton seed meal eaten by pigs during 

 a period of eighty-four days varied from eight to 

 one hundred and fifty-four pounds. After this 

 period of feeding cotton seed meal it was found that 

 the lard was actually adulterated with cotton seed 

 oil to an extent varying from four-tenths to fifteen 

 per cent, in different animals. Only one animal 

 out of the twenty three used in .this experiment was 

 badly affected by the cotton seed meal, but the 

 weather was cold during the whole experiment and 

 the pigs were given abundant exercise and large 

 quantities of succulent feed. 



The various rice products have been tested but 

 not extensively in pig feeding. Rice bran is not 

 relished by hogs and does not produce a rapid
