DESCRIPTION OF FEED STUFFS 



feeds on account of its small size and the fact that it will 

 keep well if kept dry, without danger of heating. Some 

 of the grains used in chick feeds such as cracked com are 

 apt to heat during the spring months unless thoroughly 

 kiln dried. Even these lower grades of rice are usually too 

 high priced on account of their value as a human food to 

 be used much for poultry. Rice is the highest in carbo- 

 hydrates of all the cereals but is rather low in crude 

 protein and fat. This grain appears to have a feeding 

 value about equal to corn for live stock and probably 

 not quite so much as this for poultry as it is not relished 

 or liked by poultry nearly so well as com or wheat. 



Polished rice is very deficient in some of the products 

 essential to the maintenance of life. If it is given to 

 poultry as the only source of feed it will quickly produce 

 the results caused by a feed deficient in certain essential 

 elements. Birds fed on polished rice alone become af- 

 fected with a condition called polyneuritis, the symptoms 

 of which are decreased weight and the drawing up of the 

 muscles and nerves, indicated by the drawing back or to 

 one side of the head and also of other muscles and nerves 

 on other parts of the body. If rice bran and rice polish 

 are fed with the polished rice this injurious effect on the 

 muscular and nervous systems is not apparent.
