Feeds and Feeding. 



3 Ibs. of skim milk were fed with 1 Ib. of corn meal, the second 

 where from 3 to 5 Ibs. were given to 1 Ib. of corn meal, etc. The 

 quantity of meal and milk required for 100 Ibs. of gain follows: 



Separator skim milk and corn meal required for 100 Ibs. of gain. 



Assuming that 500 Ibs. of corn meal fed alone would have pro- 

 duced 100 Ibs. of gain with these pigs, we derive the following from 

 the above data : 



Milk required to save 

 100 Ibs. of corn meal 



When feeding with each 

 pound of meal 



From 1 to 3 pounds skim milk 327 pounds 



From 3 to 5 pounds skim milk 446 pounds 



From 5 to 7 pounds skim milk 574 pounds 



From 7 to 9 pounds skim milk 552 pounds 



Average 475 pounds 



The above brings out plainly the important fact that not over 

 300 Ibs. of skim milk should be fed with each 100 Ibs. of corn meal, 

 for if more is given much of its feeding value is lost. 



885. Money value of skim milk. The feeder desirous of knowing 

 the money value of skim milk compared with corn at varying prices 

 will gain help from the following table derived from the previous 

 study: 



Money value of 100 Ibs. of skim milk. 



The table shows that when corn is worth $16 per ton, or 44.8 cents 

 per bu. of 56 Ibs., separator skim milk has a value of 24 cents per 

 100 Ibs., provided not over 3 Ibs. of skim milk is fed with each Ib.
