the higher its feeding value. Oat feed is used extensively in stock 

 and molasses feeds. Its sale in Massachusetts as a product by 

 itself is limited. Officials haxdng charge of the enforcement of 

 the feed stuff laws of some states will not recognize the term "oat 

 feed" but require manufacturers to register and guarantee feeding 

 stuffs in which it is used as containing oat hulls and oat middlings. 

 Analyses and digestion experiments made at the Massachusetts 

 experiment station show it to have the following average analysis 

 and digestibility : 



(Pounds in 100). 



About 40 percent of the dry matter in the above sample]^of 

 oat feed is digestible while whole oats show 70 percent. The low 

 digestibility of oat feed is due to the tough, woody fiber of the oat 

 hull. The addition of oat feed to a mixture lowers the digestibility 

 and feeding value of the mixture. 



Corn Cobs, in ground condition, are foimd as an adulterant 

 in wheat feeds, hominy meal and stock feeds. Their average 

 composition and digestibility are as follows:

While com cobs possess some nutritive value, their use in pur- 

 chased feeding stuffs cannot be advised. When corn is a home- 

 grown product it is believed that they can be used to advantage 

 when ground together with the com.
