In the third table we have given the total amount of digestible 

 food consumed by each lot of animals, and also the amount of 

 digestible food required in each case to produce one pound of 

 growth.

In commenting upon these results it should be remarked in gen- 

 ral, that no striking differences are observed in the rate of 

 ;rowth, or in the relation of the amount of food to growth, with 

 Aese several breeds of swine. 



(1.) The daily rate and growth of our animal is seen to have 

 been : Cheshires, 1.23 pounds; Yorkshire, 1.14 pounds; Chester 

 White, 1.08 pounds; Poland China, 1.01 pounds; Berkshire 1. 

 ound. 



(2.) It does not appear that the animals growing most rapidly 

 equired the least food for a pound of growth. The weights of 

 ligestible foods consumed for each pound of growth made are the 

 bllowing : Cheshire, 2.88 pounds; Poland China, 2.73 pounds ; 

 Yorkshire, 2.55 pounds ; Chester White, 2.5 pounds; Berkshire, 

 2.45 pounds. Although the Berkshire pigs made the smallest 

 gain they required the least food for each pound of growth, and 

 the Cheshire making the largest gain consumed the most food for 

 each pound of increase of weight. 



(3.) A careful study of the first of the above tables 

 shows plainly that the ratio of food to growth was very 

 u.fferent during the early part of the experiment from what it was 

 the latter part. In Period 1, including approximately the first
