1.102. Let us now see what the albuminoid ratio of 

 a mixed ration consisting of 17 Ibs. of hay and 6 Ibs. of 

 gram, is. We can find from the table of composition of hay, 

 as we found in the case of gram, that it contains in every 

 100 Ibs. 2 Ibs. of digestible albuminoids and 46 Ibs. of 

 digestible carbonaceous food. /. 17 Ibs. of hay contains 

 34 Ibs. of digestible proteids and 7 8 2 I DS of digestible 

 carbonaceous food or food calculated as starch. We also 

 know that 100 Ibs. of gram contains 14 Ibs. of diges- 

 tible proteids and 61 6 Ibs. (14x4*4) of carbonaceous 

 food calculated as starch. 6 Ibs. of gram would thus 

 contain '84 Ibs. of digestible proteids and 3-69 Ibs. of starch. 

 In the mixed ration therefore there is ri8 Ibs. of digestible 

 proteids and ir5i Ibs. of starch. The albuminoid ratio of 

 the mixed food is thus ri8 : 11*51 or nearly i : 10. The 

 food is thus a little too rich for horses and bullocks, though 

 not rich enough for a cow in milk nor for young growing 

 animals. 



1.103. In mixing foods the ash constituents cannot al- 

 together be left out of account. Maize and rice, for instance, 

 being extremely poor in lime are unsuitable for young and
