302 SCIENTIFIC FEEDING OF ANIMALS 



sufficient protein is given. This holds particu- 

 larly for quick-growing breeds which begin to be 

 fattened at an average weight of 80-100 lbs. The 

 carbohydrates must also be kept at a reasonably 

 high amount for young fattening pigs. 



At the beginning of the fattening period the 

 pigs can eat very large quantities of food daily, 

 up to 44 lbs. dry matter per 1000 lbs. live weight, 

 but later the appetite diminishes, and towards 

 the end the daily amount is generally not more 

 than 25-30 lbs. All these circumstances are taken 

 into account in the feeding standards in the Appen- 

 dix (Table III), which are designed for rapid 

 fattening of the large, rapidly growing breeds, and 

 assure a daily increase of 0-6-07 lb. during the 

 whole course of the fattening. 



The most intensive fattening is achieved when 

 the animals are given very digestible food mixtures. 

 The higher the digestibility of the whole diet the 

 greater is the amount of active nutrients that can 

 be given to the animals, and the better the increase 

 of weight proceeds. Indigestible feeding-stuffs, 

 such as dried grains, old green fodder, refuse from 

 cereals containing a lot of chaff, not only bring less 

 flesh- and fat-forming material into the body, but 

 also, owing to the room taken up by the undigested 

 matter, prevent larger quantities of digestible 

 nutrients from being fed. On the other hand, 

 ground cereal and leguminous seeds, maize, buck-
