342 POULTRY PRODUCTION 



The a^'e^age ainouiits of the nutrients found in 1<)() pounds 

 of fisli scrap are 12.8 ])ounds of water, 32. G pounds of ash, 

 52.4 ]ioimds of crude protein, and 2.2 pounds of fat. The 

 amounts of these di,i,'estil)le for cliickens are not known. 



Gluten Feed. — In the manufacture of glucose and corn 

 starch, the kernels of corn are soaked and separated into germ, 

 hull, gluten, and starch. The gluten is dried and ground and 

 was formerly sold as gluten meal, containing about 35 per 

 cent protein and 3 per cent fat. Because of its high concen- 

 tration it has so frecjuently produced a bad efl'ect on animals 

 when used by inexperienced feeders, and also to provide a 

 market for corn bran, it is now mixed with corn bran and 

 marketed as gluten feed. 



The bran increases the bulk, reduces the fat and protein 

 content and increases the proportionate amount of the water 

 soluble. The proportion of meal to bran is about 55 per 

 cent to 45 per cent. The protein content of gluten feed 

 varies so much that it should always be purchased on a 

 guaranteed analysis. 



Gluten feed is a valuable source of protein, as it appears 

 to be readily digested and palatable. It should never be 

 used to entirely displace protein feeds from animal sources 

 and should be accompanied by bone meal. 



The average amounts of the nutrients found in 100 pounds 

 of gluten feed are 8.7 pounds of water, 2.1 pounds of ash, 

 25.4 pounds of crude protein, GO pounds of carbohydrates, 

 of which 7.1 ])ounds are fiber, and 3.8 pounds are fat. The 

 amounts of these digestible for chickens are not known. 



Hominy Feed. — This consists of the hull, germ, and part 

 of the starch cells of the corn kernel which are separated 

 out in the process of making hulled corn or hominy. This 

 feed runs about the same as the whole grain in protein 

 and carbohydrates, but is higher in ash and fat. It is an 

 excellent poultry feed, but is not used extensi^'ely because 

 of the limited supply. 



The average amounts of the nutrients found in 100 pounds 

 of hominy feed are 10.1 pounds of water, 2.G pounds of ash, 

 lO.G pounds of crude protein, G8.7 pounds of carbohydrates, 

 of which 4.4 pounds are fiber, and 8.0 pounds of fat. The 

 amounts of these digestible for chickens are not known.
