Earth-nut shells and rice husks are seen to be 

 practically worthless, coffee and millet husks lower 

 the feeding value of the other food, whilst the oat 

 husk is no better than straw. Of the 26-7% crude 

 protein in Bassia meal only -7% digestible proteins 

 are present. 



When the percentage composition of a food has 

 been determined by analysis, then the quantity of 

 digestible nutrients, and from that the amount of 

 digestible protein and the starch equivalent, can be 

 calculated according to the method given in the 

 tables in the Appendix. 



With regard to the palatableness of the various 

 food-stuffs and the quantities that can be fed 

 without injury, practice has furnished certain data 

 which will be mentioned when the several food- 

 stuffs are described. The descriptions it must not 

 be forgotten apply only to good samples, not to 

 those materials which have been injured by moulds 

 or fungi, etc. Further, there may be admixture 

 with injurious substances or the foods may have
