FIFTY-THIRD ANNUAL CONVENTION 39 



However, if corn and milk are mixed together in the 

 right proportion to make a balanced ration, then the pigs 

 will use for growth over 60 per cent of the proteins in the 

 milk and corn combination. In other words, we can take 

 this poor corn protein and mix it with the right proportion 

 of good milk protein and make an exceedingly efficient 

 mixture — a mixture which will be just as good as pure 

 milk protein. 



These results are due to the fact that milk protein is 

 richer than linseed meal in some of the building stones or 

 amino acids which corn lacks. Therefore, the rich supply 

 of these amino acids makes good the deficiency in the corn 

 grain. This is an exceedingly important matter in feeding 

 certain classes of stock. In feeding pigs, especially those 

 not on pasture, it is of vital importance. 



I have never yet seen good results in pig feeding where 

 a man has fed young pigs not on pasture such a ration as 

 corn and middlings or corn and linseed meal. Why is this? 

 One of the primary reasons is that the protein in such a ra- 

 tion is not of the right kind or quality. 



If some of you have a flock of chickens at home from 

 which you are not getting many eggs, the fault may be in 

 the ration the chickens are receiving. If they are getting 

 corn, oats, linseed meal, wheat middlings, and wheat bran, 

 do not blame the chickens at all. Blame the quality of the 

 protein in the ration. If you would put some meat scraps 

 or plenty of skim milk in the ration, and be sure the chick- 

 ens are provided with enough mineral matter, they would 

 be able to manufacture more eggs, because they would have 

 the right kind of raw material. 



In all stock feeding operations, look at your animals 

 simply as machines which convert the products of your 

 fields into finished products, like meat, eggs, etc. You can 

 not expect a machine to manufacture steel rails from wood- 

 en timbers, can you? Neither can you expect a pig to manu- 

 facture pig meat from corn protein alone. You must have 

 the right kind of raw material and in the proper amount. 



This is a matter of vital importance in swine feeding. 

 For instance, in one experiment we have carried on, pigs
