Number or Cows 



FiGUEE 6. Relation of number of cows pi-r farm 

 to cost of milk and labor income. 



Milk Production per Cow 



This also contributed to an increased volume of milk. That it had 

 a striking effect on cost of milk production is shown in Table 80. With 

 an average production per cow of 2,809 pounds, the average cost of 

 milk per hundredweight was $4.72; but with an average production 

 of 7,238, milk was produced on 56 farms at an average cost of only 

 $2.23. With milk relatively high-priced and grain comparatively low 

 in price, production per cow probably had the most important "influ- 

 ence on cost of milk production. By increasing production, the opera- 

 tor gets much more milk per man with little additional expenditure of 

 time and little, if any, extra cost for labor.
