INFLUENCE OF AGE ON VALUE OF COWS AND HOESES. 



11 



AH 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 wiU be worth less at the same age 

 when there is smaller demand, but there will be a corresponding 

 fluctuation in value for all other ages. It is, therefore, believed that 

 the tables, especially the percentage table, will be found useful in 

 determinmg relative value according to age. 



Figures 1, 2, 3, and 4 present in graphic form the data for each 

 class of all four breeds as given in Tables I, II, III, and IV. These 

 curves indicate that the difference in value 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 roaches 

 his maximum value at some point between six and seven years of age.
