SCIENTIFIC FEEDING OF ANIMALS 



organs are inflamed. It can also be used for feeding 

 sickly animals, but is often successfully replaced 

 by the cheaper linseed cake. Of the other oily 

 seeds use is sometimes made of those of rape, 

 colza, hemp, sunflower, etc., and the properties of 

 them and of the cake prepared from them will be 

 discussed later. All oily seeds should be crushed 

 before being fed. 



Beech mast, which is also fairly rich in oil, con- 

 tains a poison that is injurious to some animals 

 (horses), and should, therefore, only be given in 

 moderate quantities to grown pigs and fattening 

 cattle. 



Acorns and horse chestnuts are most valuable 

 for the fattening of pigs and oxen, but owing to 

 their astringent taste they are not always readily 

 eaten. When given fresh they should be crushed, 

 when dry they may be ground. 



(5) By-products from flour mills. 



In the manufacture of human food from the seeds 

 of the cereal and leguminous plants, a large number 

 of by-products are obtained, both in the preliminary 

 preparation and in the process of grinding. In the 

 refuse from the cleaning machines there are, in 

 addition to casual impurities, non-fertile and broken 

 grains, small stones, earth, sand, mouse droppings, 

 as^well as various weed seeds, rust spores, particles
