120 THE SCIENTIFIC FEEDING OF ANIMALS 



Formerly, aspiration of the too abundantly present fibers caused dis- 

 ease of the lungs and bronchi, and pieces of wire from the cotton gins 

 have caused internal injuries. To avoid accidents of this nature, cot- 

 tonseed by-products, unless they are dependable wares, should be care- 

 fully screened and, if necessary, moistened before feeding. 



The daily ration of cottonseed by-products for milk cows and horses 

 should not exceed 2 pounds, for working oxen, ,4 pounds, fattening cat-

 Cocoanut by-products. — Origin : Cocoanut palm, Cocos nucifera, Fig. 

 52. The cocoanut is enclosed by an outer fruit covering (Fig. 53, a), 

 within which are the fibrous envelope, b, which is used as material for 

 making mats, the inner fruit shell, c, from which are manufactured 

 buttons, trinkets, etc. and the seed (copra, e), which furnishes the cocoa- 

 nut oil. The by-products serve as feeding stuffs.
