PIG FEEDING EXPEKIMENTS. 



BY C. A. GARY. 



These feeding tests were made for the purpose of securing 

 a ration — of which cotton seed or cotton seed meal shoukl 

 form one of the principal ingredients — that would not kill 

 pigs and yet be a profitable food. At the same time it was 

 our aim to attempt to determine the reason why cotton seed 

 or cotton seed meal kills pigs ; this part of the experiment 

 was not fully carried out, because no pigs were killed by the 

 feeding tests. 



These tests must be considered as preliminary ; because 

 their number and the repetition of the same tests are insuf- 

 ficient to make fixed or definite feeding laws. In order to 

 obtain definite conclusions, repeated and various tests must 

 be made, and in connection therewith chemical analyses of 

 the ration as fed and of the indigestible parts of the ration 

 must be made. 



In these tests we were controlled by limited means and 

 difficulties in obtaining the foods desired at the time when 

 needed. However, it was our intention to use such foods 

 as were in season and most available to the farmer. 



First Experiment. (See table No. I.) 



In calculating the cost of the rations in the tests, made 

 from April 28th to August 11, 1894, the following prices were 

 used: Corn, 60 cents per bushel; cow peas, 60 cents per 

 bushel; sweet potatoes, 50 cents per bushel; green oats, 

 green rye and green sorghum, each <tt 25 cents per cwt. ; 

 wheat bran and cotton seed meal at |20 per ton ; cotton seed 

 at 12^ cents per bush. Since I could find no digestible per-
