Experiments with Lots 5 and 6. 



Four pigs were again selected from a litter, and when they had 

 reached a weight of over thirty pounds, the two lots into which 

 they were divided began to receive radically different rations. 

 Lot 5 was fed from Nov. 7th to Dec. 8th on skimmed milk, corn 

 meal and potatoes, and Lot 6 on corn meal and potatoes. On 

 Dec. 9th the skimmed milk in the ration of Lot 5 was replaced by 

 pea meal, the materials of the rations of Lot 6 remaining 

 unchanged, and this feeding was continued until March 26th. 



It was realized before hand that it might be difficult to get a sat- 

 isfactory development of the animals of Lot 6 with such a ration, 

 and this proved to be the case, though the pigs seemed vigorous 

 and healthy. It was found impossible to induce this lot to eat, 

 without waste, more than a very moderate amount. Lot 5, on the 

 contrary, would have eaten very much more than the ration 

 allowed, even after the pea meal was substituted for the milk, but 

 the food of this lot was limited to the amount fed to Lot 6. Con- 

 sidering the quantity of food eaten, the gain of Lot 5 was very 

 satisfactory. 



From March 26th until the following October, the pigs of Lots 

 5 and 6 were all fed on skimmed milk, bran and corn meal, and 

 the animals of Lot 6 regained their lost ground, and reached prac- 

 tically the size and condition of Lot 5, their average live weight 

 on Oct. 10th, being about 275 lbs. It was the intention at this 

 time to have put these animals on the market, but as it was thought
