APPENDIX 



TABLES FOR THE CALCULATION OF 

 RATIONS 



Method of using the Tables 



TN making up rations care must first of all be 

 -* taken that the foods which are to compose the 

 ration are such as are suitable for the animals for 

 which they are intended, and that they have 

 already been successfully used in practice. Each 

 food which it is proposed to use in the ration should 

 then have its nutritive value ascertained, for which 

 purpose the contents of (a) crude nutrients, (b) 

 digestible nutrients, (c) starch equivalent should 

 be determined. If the food-stuff after analysis 

 possesses a different composition to that given in 

 Table I, then, with the help of Table II, the amount 

 of digestible nutrients must be calculated. For this 

 purpose the digestibility coefficients of materials 

 of a similar kind are used. It would be quite 

 wrong if the coefficients for grass were applied to 

 clovers, even though the analyses of both were 

 similar.
