All of the other proprietary grain mixtures collected contained 

 no' low grade products, and it simply remains for the feeder to 

 determine under his own conditions whether it is more economi-, 

 cal to mix his rations from the standard, by-products found on the 

 market or to purchase these ready mixtures. It is believed that 

 any of them will prove satisfactory. As a rule it is believed the 

 feeder can purchase staple feedstuffs and compound his own 

 feed mixtures for less money than by purchasing the ready rations. 



Feeds of this character appear to increase from 

 Molasses Feeds year to year. Most of them makeuseof prod- 

 (More than 15% ucts that, while they are excellent absorbents 

 Protein) Pages for molasses, have a low feeding value. Some 



34-35-36 of the more common low-grade products used 



in molasses feeds are as follows 



Grain screenings contain the smaller imperfect grains, weed 

 seeds, chaff and other foreign material separated in cleaning 

 grain. Screenings naturally partake, to a certain extent, of the 

 characteristics of the seeds from which they are derived. It 

 is -frequently noted that molasses feeds are certified to contain 

 "ground and bolted grain screenings". This is an indication of 

 better mechanical condition and practically no screenings are 

 used at the present time in molasses feeds that have not under- 

 gone this process. Certain weed seeds such as the wild mustard 

 are sometimes separated from the screenings as having greater 

 commercial value by themselves than as a component of a molas- 

 ses feed. The statement that a molasses feed contains the mixed 

 broken grains of cereals does not necessarily indicate any real 

 addition to the mixture as all screenings contain these seeds. 



Clipped oat by-product results in the preparation of clipped 

 oats and contains the light chaffy material broken from the ends 

 of the oat hulls, empty hulls, light immature oats and dust. It is 

 an excellent absorbent for molasses. 



Oat meal mill by-product is simply the by-product obtained 

 in the manufacture of rolled oats and consists largely of oat hulls 

 together with some light oats and oat middlings. 



Cocoa shells are the waste hulls from the cocoa bean in the 

 manufacture of chocolate. Their real feeding value is problem- 

 atical. 



Ivory nut meal is made from the waste vegetable ivory ob- 

 tained from button factories. In spite of its hard bony ap- 

 pearance it appears to have considerable feeding value when 

 finely ground. 



Molasses feeds contain so much material of inferior quality 

 that it has been found necessary to expend considerable ingenuity
