PRINCIPLES OF FEEDING FARM ANIMALS 



allowed to forage at will. They are not grown in the corn- 

 belt to any extent. 



Field beans are grown principally for human food, but 

 the culls and damaged beans are often available for stock 

 feed in certain sections of the country. Their composition 

 is very similar to that of cowpeas. They may be fed whole 



in large quantities to 

 sheep, producing a solid 

 flesh of good quality. 

 Better results probably 

 would be obtained by 

 feeding them with corn. 

 For hogs, they should be 

 cooked in salt water and 

 fed with corn or barley, 

 as they produce a soft 

 pork when fed alone.

form of fat or oil rather 

 than as starch. The oil-bearing seeds contain as much as 40 

 per cent of fat in some cases. They are also quite high in pro- 

 tein. Fat or oil being too valuable for use in large quantities 

 as a stock feed, it usually is pressed or extracted from the seeds, 

 the residue in the form of a cake or meal being used for stock 

 feeding. The use of these by-products will be discussed later. 

 The principal oil-bearing seeds of interest are cottonseed and 

 flaxseed. According to our classification, the soy bean and pea- 

 nut also fall in this class as well as in the class of the legume seeds.
