Feeds and Feeding. 



Assuming that 500 pounds of com meal, fed alone, vould have 

 produced 100 pounds of gain with these pigs, we find that with 

 the first group 585 pounds of skim milk effected a saving of 179 

 pounds of com meal. On this basis, 327 pounds of skim nulk 

 equals 100 pounds of com meal when not over three pounds of 

 milk are fed with each pound of meal. Calculating the value of 

 skim nulk in connection with com meal for pig feeding according 

 to the proportion fed with the meal, we deduce the following: 



When feeding 1 pound of com meal with from 1-3 pounds of separator 



skim milk, 327 pounds of skim milk saves 100 pounds of meal. 

 When feeding 1 pound of com meal with from 3-5 pounds of separator 



skim milk , 446 pounds of skim milk saves 100 pounds of meal. 

 When feeding 1 pound of corn meal with from 5-7 pounds of separator 



skim milk , 574 pounds of skim milk saves 100 pounds of meal. 

 When feeding 1 pound of com meal with from 7-9 pounds of separator 



skim milk, 552 pounds of skim milk saves 100 pounds of meaU 

 Average of aU, 475 pounds of skim milk equals 100 pounds of meaL 



Fjord's experiments show six pounds of skim milk equal to one 

 pound of grain. The difference in the ratios is doubtless due to 

 the fact that Fjord fed a much larger proportion of milk to meal 

 than was usually employed in the "Wisconsin trials. (357, 888)

 varying prices will find the following table of value:
