Set B. 



Set A consumed a total of 1495.5 pounds of meal and 1470 

 pounds skim milk, and gained 378 pounds, thus requiring to pro- 

 duce one pound of growth, 3.95 pounds of meal and 3.89 pounds 

 of milk. Set B consumed 1515.5 pounds of meal and scrap, and 

 gained 388.5 pounds, requiring 3.9 pounds of the mixture for one 

 pound of growth. Probabl}' the reason for the low gain made by 

 set A during the sixth and seventh periods, may be found in the 

 fact that the}' were heavih' loaded with fat, and veiy ripe, requiring 

 much elfort to get about their pens. Throughout the trial the tend- 

 enc}' of' set A was to fatness, while set B grew vigorously but 

 did not become very fat. This result, must, I think, be ascribed to 

 the different foods employed and not to peculiar tendencies existing 

 in the animals, as they were well bred, and at the commencement of 

 the trial very evenly mated, as the pigs in each set continued to 

 be throughout. From the table it will be observed that. aS they 

 advanced in age and size it required a greater quantity of food to 

 produce a pound of increase. The showing of set A is not favor- 

 able to the feeding value of milk, but the test in this case was not 

 just, .for the}^ were fed bej'ond the point of profit in the sixth and 

 seventh periods. How far the milk in their ration was influential in 

 producing such earl}' maturity and ripeness is a point upon which we 

 shall seek further light. At the expiration of the seventh period 

 the pigs in set A were butchered. Live weight of set was 548 

 pounds. Dressed weight, 470 pounds. Shrinkage, 78 pounds, or 

 14| per cent.
