(i'5 per cent.) which is equal in value to starch, are digestible. 

 We also conclude, that 85 percent, of the albuminoids, the 

 proportion of which is 17-1, is digestible. Now the proportion 

 between the digestible albuminoids and the digestible por- 

 tions of the food reckoned as starch is the true albuminoid 

 ratio of gram. In working the proportion out we have the 

 following result: 



17 i X 85 



(57 * 9) + ( l '5 x 9) + (6-3 x 60) + (4*4 x 2-3 x 80) 



_ = ,'ff 8 + 8 . 09 6 = gjjj " ' ' 4-4 



1.099. The food of a working bullock should .have an 

 albuminoid ratio of i : 13; of horse i : n ; and of a cow in 

 milk i : yj. Cow's milk which is highly nutritious food has 

 the albuminoid ratio of 1:5 a'nd of goat's milk i : 4.7. Food 

 of young and growing animals should, therefore, have the 

 albuminoid ratio of i : 5. 



1.100. In mixing different foods for farm animals the 

 albuminoid ratio suitable for each should be borne in mind 

 as much as possible that economy in feeding may be attended 

 with the best of results. If the albuminoid ratio is too high 

 it is waste of good food, if it is too low the food is too poor 

 as a flesh-former.

 idea of the value of different foods for animals.
