there is a larger proportion of the nutrients digested in the case of the latter. 

 Buying on a protein-fat basis the higher-priced linseed-meal would be the cheaper 

 in this case. 



The " Commercial Feeding Stuffs Act " of Canada requires that most of the 

 milling and manufacturing products sold as feeds (except bran, shorts, and the 

 meal of whole grains) bear on each sack the guaranteed percentage of protein, 

 fat, and fibre in the feed. It should be remembered that it is usually the total 

 percentage of these nutrients that is given and that this is not wholly digestible. 

 Only the digestible part of the ration is used by the animal. For the guidance of 

 buyers of feed-stuffs both the total nutrients and also the digestible part of these 

 are given in Tabl> - 



TaMe 1 will be found useful in " balancing " a ration to make it conform to the 

 standards generally accepted for average-weight cows. These standards are not 

 arbitrary, but will be useful as a guide in compounding rations economically. 



CLASSIFICATION OF FEED ACCORDING TO THEIB NUTRITIVE RATIOS. 

 (Based on Bulletin 92, Washington Experiment Station.) 



NOTE. The nutritive ratio is the proportion of protein to carbohydrates, 

 means that the feed contains 1 of protein to 5 of carbohydrates.

A cow must relish its food to eat the maximum amount. To milk well she must 

 eat well. Much hay is allowed to get woody and unpalatable before cutting, and 

 often the best parts, the leaves, have fallen off before it is fed. Silage and roots 

 are well liked, and a mixture of silage, pulped roots, and grain is greatly relished.
