PRINCIPLES OF HORSE BREEDING

Table VIII of the Appendix, 12 pounds of timothy hay, 

 five pounds of corn and five pounds of oats. If we arrange 

 these in a table and compute the digestible nutrients in 

 each, according to the Wolff-Lehmann method, we get 

 the following: 



According to the Wolff-Lehmann standard (p. 331), 

 this ration is deficient in protein and rich in carbo- 

 hydra*" .thereby giving a nutritive-ratio of i : 10.4, 

 insteaa ji : 7.0, as called for in the standard. Accord- 

 ing to this standard, the ration could be improved by the 

 addition of one pound of linseed meal. 



Let us use the same food and calculate a ration by the 



Armsby standard (p. 331) for a 1,000-pound horse at light 



c4rk. Taking the composition from Table VII of the 



Appendix and arranging the nutrients and energy in a 



table, we get the following: 



According to the Armsby standard this ration, al- 

 though composed of the same kind and amount of food 

 as before, is slightly too rich in digestible protein and 

 considerably so in energy value. This serves to em- 

 phasize the statement that feeding standards should 

 serve as mere guides, to be modified according to atten- 

 dant conditions.
