THE DIGESTIBILITY OF CATTLE FOODS. 



115 



The experiment shows this particular lot of hay to compare 

 favorably with all previous trials of mixed hay composed of 

 similar grasses. 



CXX Feed. 



This feed is a product from the Postum Cereal Company's 

 works, and is probably the residue from the manufacture of 

 Instant Postum, prepared by roasting a mixture of wheat, 

 wheat bran and molasses. 



Summary of Coefficients, CXX Feed, Series XVIII., Period IX. 



The results of the experiment show the CXX Feed to have a 

 very low digestibility, probably due to the roasting that the 

 product undergoes. The protein and fiber appear to be of 

 little nutritive value, and the material as a whole must be pro- 

 nounced quite inferior for feeding purposes. 



Fish Meals. 

 Two varieties of fish meal were used in these experiments. 

 The first, Gloucester fish meal, was received from the Russia 

 Cement Company, and is a by-product from the manufacture 

 of fish glue. The second is a by-product from the menhaden 

 fisheries, and up to the present time has been used almost en- 

 tirely as a fertilizer. It had not been treated with sulphuric 

 acid. The fish guano contained more fat and less ash and 

 protein than did the Gloucester fish meal. In some European 

 countries dried fish and even the raw refuse is used as a food 

 for domestic animals.
