MANUAL OF FARM ANIMALS 



FOOD REQUIREMENTS FOR SWINE 



The food required for a given gain among swine varies with 

 the kind of food and the age and weight of animals. Foods 

 vary largely in the energy they contain. The older and the 

 larger the animal the more food required for a given gain. 

 Wolff and Lehman, after much experimentation along this line, 

 have given us the following standards : — 



Wolff-Lehman standard, showing the amount of food required per 1000 

 pounds live weight for both growing and fattening swine 



As with the standards for horses, cattle, and sheep, these 

 are arranged to meet the need of the average farm hogs 

 under normal conditions. They are not intended to be abso- 

 lute.
