THE FEEDING VALVE OF SKIM MILK. 85 



growth, from one bushel of 70 pounds of ear 

 com. Lot III was fed skim-milk and com in 

 proportion of one bushel of com to 100 pounds 

 of skim-milk. This combination produced 18 

 pounds of growth. 



This illustrates very nicely the economy of 

 feeding a combination of com and skim-milk. 

 When the buskel of com and 100 pounds of 

 skim-milk were fed separately, they made 15 

 pounds of growth; when fed together they made 

 18 pounds' growth, an increase of 20 per cent. 



Personal Experience with Skim-milk. — ^In my 

 early experience in dairying I wished to have 

 some reliable basis upon which to estimate the 

 value of skim-milk, and there were so few ex- 

 periments available at that time that I felt it 

 advisable to do a little experimenting myself. 

 I found that there is no food so good as skim- 

 milk to make muscle, bone and growth in pigs 

 when fed intelligently. Many farmers have a 

 belief that they need to feed a large quantity of 

 skim-milk because it contains no cream.; this is 

 a mistake and in many cases a fatal mistake, 

 as too much of it causes scours, which if not 

 checked soon will ruin the pigs. 



My first experiments were made in the early 

 seventies by feeding skim-milk without other 

 food and the results showed that with pigs 

 weighing 50 to 75 pounds each, I secured one 

 pound of growth from 16 pounds of skim-milk
