TABLES — READY RECKONER — EXAMPLES 107 



This ration should prove satisfactory from the feeding 

 point of view, but the question of cost must still be 

 considered : 



21-61d. 

 i.e., slightly over Is. 9|d., or 12s. 7Jd. per week. 



The cost of the new ration is, therefore, slightly in 

 excess of the old one, but it will be more than made 

 good in the condition and efficiency of the horses, 

 which will now receive a ration up to the standard 

 requirements. 



It may be pointed out that the nitrogenous ratio falls 

 slightly outside the optimum 1:6. To improve this 

 a further 1 lb. of peas might be substituted for 1 lb. of 

 oats or 1 lb. of bran, and the calculation of the value 

 and cost of the new ration under each of these substitu- 

 tions will afford a useful exercise in the manipulation of 

 the tables.
