of ash and has a nutritive ratio of 1 to 7.7 for chicl<ens. 'i'he 

 crude fiber content is 10.8 pounds. 



Rice. — While rice is classed as a fattening feed because of its 

 hirge proportion of carboli\'drate, nevertlieless it is considered 

 an excellent feed for little chicks because of its regulating 

 cll'ect on the bowels. It is usually fed in tlie grain portion 

 of the ration. In the case of a tendency toward bowel trouble, 

 however, it is frequently l)oile(l. The boiled rice is fed as a 

 wet mash, and the water drained off and given the chicks to 

 drink after being cooled. 



The average amf)unts of the nutrients found in 1(H) pounds 

 of polished rice are 12.3 pounds of water, 0.5 pound of ash, 

 7.4 ]X)unds of crude protein, 79.4 pounds of carbohydrates, 

 of which 0.4 ])ound is crude fiber, and 0.4 pound is fat. 

 The amounts digestible for chickens are not known. Hughes' 

 found that ])igeons fed on polished rice only, developed poly- 

 neuritis in twenty to twenty-eight days. These birds could 

 be cured by feeding tlie ])olishings, which goes to show that 

 there is little water soluble B in ]5olislie(l rice, but an abun- 

 flance in the outer coating, taken off in the ])olishing process. 



////r.— This grain, altliough cjuite similar to wheat in com- 

 ])osition, is not suited for poultry feeding. It seems to 

 contain some ingredient which renders it un]ialatal)le to the 

 fowl though this is ])ossibly due to low ])er cent of fat. When 

 fowls are compelled to eat it, it has a tendency to cause 

 digesti\'e disorders and aU'ect the flavor of the egg. 



The amounts of digestible nutrients found in 100 pounds of 

 rye as determined by digestion experiments with chickens 

 are 7.5 pounds of protein, 0.48 pounds of fat, and 64.6 

 pounds of nitrogen-free extract. It contains 2.1 pounds of 

 ash and has a nutritive ratio of 1 to 8.7 for chickens. The 

 crude fiber content is 1.5 pounds. 



Sunflower Seeds. — The high fat content (21 per cent) 

 of sunflower seeds, makes them highly jirized for feeding birds 

 intended for exhibition. The oil produces a, desiral)le floss 

 that is iiuich sought. Their high filler content (nearly lid ])er 

 cent) and the prevailing high ])riccs render them uniirofitable 

 for feeding except for the ])urpose noted abo\e.
