THE NUTRITIVE VALUE OP CERTAIN FEEDS.

meal. Judging from its analj'sis it probablj^ contains 1,000 pounds of 

 t'lioice cottonseed meal and 1,000 pounds of cottonseed hull bran to the 

 ton. 



(4) Conclusions. 



I. On the basis of analyses made during the last seventeen years, it is 

 evident that the quality of cottonseed meal sold in ■Massachusetts is 

 gradually growing poorer. 



II. The addition of cottonseed hulls or cottonseed hull bran to choice 

 cottonseed meal noticeably decreases its digestibility. 



III. Cottonseed feed meal, being a mixture of api)roximately 1,000 

 pounds of choice cottonseed meal and 1,000 pounds of cottonseed hull 

 bran, does not have much over one-half the feeding value of choice cot- 

 tonseed meal, while it sells for three-fourths as much. 



IV. Wliile cottonseed hulls and cottonseed hull bran can probably be 

 used to advantage in the south, they are not worth the consideration of 

 the northern feeder, either as a product b}^ themselves or as an admixture 

 in good cottonseed meal. 



3. COCOA SHELLS. 



Cocoa shells are the hard, outside coating or bran of the cocoa bean. 

 Thej^ are dark brown in appearance and brittle in texture. They comprise 

 from 10 to 16 per cent, of the bean. The entire residue, however, removed 

 from the bean and included as cocoa shells amounts to from 16 to 25 per 

 cent. The output for the United States has been estimated at 6,700 tons. 

 Up to the present time their use in tliis country as a feeding stuff has 

 been quite limited, although they are now known to be used in several 

 poultry mashes and in one brand of calf meal. In Europe they are used 

 as a partial food for horses and cattle and as an adulterant for oil cakes. 

 Large quantities are also used by the Swiss as a feed for draft oxen, thus 

 utihzing the residue from their chocolate factories. It is held that they 

 act as a stimulant to the nerves and muscles and enable the animals to 

 do a greater amount of work. '
