COST VS. VALUE OP A GOOD DAIRY SIRE. 



Wilbur J. Fraser, Chief of Dairy Husbandry, University of Illinois, in 



Wallaces' Farmer. 



A few poor cows may do little permanent harm to the dairy herd, but a 

 poor sire will do untold damage. Frequently dairymen hold the penny so 

 close to the eye it is impossible to see the dollar a little farther off, and 

 this is just what a man is doing who has a good dairy herd of grade cows 

 and thinks he is economizing by buying a poor or even common sire. 



If the good pure-bred sire improves the milking capacity of his 

 daughters only one and one-half pounds of milk at a milking, above the 

 production of their dams, this would mean an increase of 900 pounds of 

 milk for the ten months or 300 days an ordinary cow should give milk. 

 The daughter would also be a much more persistent milker; that is, 

 would give milk for a longer time in the year, and she would regain her 

 flow of milk better after an unavoidable shortage of feed as In a summer 

 drouth. These daughters may certainly be credited with 1,000 pounds 

 more milk per year than their dams produced. At the low estimate of 

 $1 per 100 pounds this extra amount of milk would be worth $10 per 

 year. The average cow is a good producer for at least six years, or until 

 she is eight years old. It will on the average be four years after pur- 

 chasing the sire before his first daughters will have brought in the first 

 extra $10. Eight dollars and twenty-three cents kept at compound interest 

 for these four years at 5 per cent will equal $10, so the daughter's 

 improvement or increase of income the first year is worth $8.23 at the 

 time her sire is purchased. The cash value of the daughter's improve- 

 ment (inherited from the sire) figured in the same way for each of the 

 six years she gives milk is shown in the following table: 



Improvement first year $ 8.23 



Improvement second year 7.83 



Improvement third year 7.46
