INFLUENCE OF AGE ON VALUE OF COWS AND HORSES. 11 
All classes of live stock vary in actual value from time to time, but 
such variation does not greatly affect the relative value of the animal 
at different ages. A cow worth $100 at 3 years of age when there 
is a great demand for dairy cattle will be worth less at the same age 
when there is smaller demand, but there will be a corresponding 
fluctuation in value for all otherages. It is, therefore, believed that 
the tables, especially the percentage table, will be found useful in 
determining relative value according to age. 
Hisures) 1,2, 3, and 4 present in graphic form the data for each 
class of all oa breeds as given in Tables I, II, III, and IV. These 
curves indicate that the difference in ae between the various 
classes of the same breed is greatest when the animals are in their 
prime and least for calves and old cows. It is also clearly shown 
that the curvature increases for each succeeding class from the $80 
grade to the $300-purebred. This may be explained in part by saying 
that the price of grade cows is influenced largely by production, that 
the price of the $200 purebred includes production and registration, 
and that in determining the price of the $300 purebred three major 
factors must be considered, production, registration, and advanced 
registry.

Table VI shows the estimated influence of age on the value of farm 
work horses, and the per cent that the value at any age is of the 
maximum value. The estimates are for the farm horse worth $250 
in his prime. ‘This is a value much above that of the average farm 
work horse, but the per cent columns may be used within reasonable 
limits in determining the influence of age on the values of cheaper 
farm horses. According to these figures the farm work horse reaches 
his maximum value at some point between six and seven years of age.
