HOW TO FEED YOUR HOGS 



What ratio should we figure on feed for the different classes of 

 swine ? We can only give this approximately because it varies, de- 

 pending largely on the quality of protein, and character of the 

 carbohydrate equivalent, but assuming a rather good quality of 

 protein present, and average carbohydrate equivalents, we find 

 that the approximate practical ratio to allow different classes of 

 swine is, in general, as follows : 



It is to be re-emphasized that these figures are approximate, but 

 nevertheless they can be used as a good general guide. Remember, 

 that this is drylot feeding. On pasture it is well to follow the rec- 

 ommendations given for pasture as to the amount of tankage or 

 its equivalent. It is to be remembered that pigs on pastures get 

 most of the protein from them, particularly if the pasture be al- 

 falfa, rape, red clover, green rye, green wheat, or young tender 

 bluegrass, and it is ordinarily difficult to estimate just how much 

 material pigs get from such pastures; hence we have to approxi- 

 mate the ratios to allow on them, basing our figures largely on our 

 practical experience. 



Ratio for Breeding Pigs. In order to convert the tankage in 

 the above table into skimmilk, multiply by approximately 20. For 

 instance, breeding pigs require ratio of about 3.5 to 4.0, which is 

 secured by allowing 25 to 18 pounds of tankage with every 100 

 pounds of corn. If skimmilk is used, it will take twenty times as 

 much as the 25 to 18 of tankage or 500 to 300 pounds of milk with 

 every 100 pounds of corn, or from about 5 to 3% pounds of milk 

 (skim or butter) with every pound of corn grain. This conver- 

 sion is not absolutely accurate, but it is approximately what we 

 wish, and should give good general results. 



One can now figure for himself on the basis of what has been 

 said any ration that he wishes. Suppose you have pigs weighing 

 75 to 100 pounds to feed. Look on the table and you will find that
