Coffee Refuse. 



This material was the residue from the coffee bean, and was being used as a com- 

 ponent of a low-grade feed mixture. It contained 93.77 per cent of dry matter, 

 which was composed of ash 5.29, protein 13.29, fiber 33.86, nitrogen-free extract 

 40.98 and fat 6.58. It was fed in combination with hay and gluten feed to the 

 extent of about 16 per cent of the dry matter of the ration. One sheep refused the 

 mixture, while the other ate it but digested only a small portion. It evidently had 

 very little nutritive value. 



Cottonseed Meal. 



The sample contained 92.90 per cent of dry matter, which had 7.40 per cent of 

 ash, 39.35 per cent of protein, and 20.05 per cent of fiber, the latter ingredient being 

 some 8 per cent above the average. It is evident that considerable ground hulls 

 had been added, and the above coefficients show that such an admixture caused 

 the digestibihty to be below that for the better grades. As is well known, cotton- 

 seed meal is sold on a basis of from 43 to 36 per cent protein ; the latter grade results 

 from the addition of ground hulls, which naturally reduces both its feeding and 

 fertilizing value.
