178 EXPERIMENT STATION RECORD. 



which it was calculated they gained from the grain fed during stormy 

 weather. On the supposition that 4.5 lbs. of grain are required to pro- 

 duce a pound of pork the 41 pigs gathered 3,238.75 lbs. of grain which 

 otherwise would have been lost. The harvesting had been done in the 

 usual manner, and in the author's opinion the amount of peas and grain 

 remaining in the fields did not exceed that in the stubble fields on the 

 average farm. 



Seven brood sows were afterwards pastured during the winter on the 

 station stubble fields, which included a 24-acre oat field in addition to 

 those mentioned above. They were given no food in addition to what 

 they could gather, except kitchen slops and a small grain ration on 

 stormy days. "The sows frequently rooted down through in. of snow 

 and found sufficient grain to keep them in good condition throughout 

 the entire winter.'' 



November 21, 38 pigs from the lot which had been pastured on stubble 

 fields, and 11 others, farrowed about the same time, were divided into 

 one lot of 13 and three lots of 12 each. The pigs averaged about 120 

 lbs. in weight. They were pure and grade Poland Chinas and grade 

 Chester Whites. Lot 1 was fed barley; lot 2, barley and wheat, 1:1; 

 lot 3, barley and peas, 1:1; and lot 4, barley, peas, and wheat, 1:1:1. 

 The barley and wheat were fed ground and dry, as it was found that 

 when fed whole some grain passed through the pigs undigested. The 

 peas were fed whole and were well masticated. The test was divided 

 into three periods of 32, 21, and 23 days. One pig was dropped from 

 lot 3 at the end of the first period. 



The wheat was rated at $1, barley at 65 cts., and peas at 70.7 cts. per 

 hundred pounds. The food consumed and gains in weight made : dur- 

 ing the different periods are recorded. At the close of the experiment 

 the pigs were sold at 3J cents per pound live weight. 



During the first period the average daily gains for the four lots were- 

 1.62, 1.65, 1.02, and 1.75 lbs., respectively; and the food consumed per 

 pound of gain, 4.89, 4.64, 4.53, and 4.36 lbs. During the second period 

 the average daily gains were 1.68, 1.63, 1.69, and 1.71 lbs.; and the food 

 consumed per pound of gain, 5.05, 5.06, 5.01, and 4.82 lbs., respectively. 

 During the third period the average daily gains were 1.21, 1.22, 1.15, 

 and 1.27 lbs., the amounts of food consumed per pound of gain being 

 6.71, 6.45, 6.51, and 5.90 lbs. 



Among the conclusions reached were the following: 



"Pigs make the greatest gains and consume less grain per pound of gain before 

 they reach 200 to 210 lbs. in weight. 



"The quality of pork produced from wheat, barley, and peas in the various com- 

 binations used is firm and well adapted for the production of hams and bacon, the 

 fat and lean of the meat being well distributed. 



"Pigs fed on barley or barley and wheat at present market prices will pay for all 

 food consumed when pork is 3i cents a pound. 



"The pea combiued with grain is well adapted to the wants of the growing ani- 

 mal, and will give the greatest gains on the smallest amount of feed."
