Succulent Feed 



Somewhat similar results were obtained in Table 87 by arranging 

 these farms according: to the amount of succulence fed. The climate 

 of this region is near the limit for economical corn production. Some 

 of the farms away from the Connecticut River which have a short 

 growing season because of elevation or frost pockets are ill adapted 

 to producing silage corn. The average amount of succulence used per 

 cow in this region Avas less than a ton and a half. On about one-third 

 of the farms no succulence was used.

The lowest average cost of milk production occurred in the group 

 which fed an average of 7,775 pounds of succulence per cow. A full 

 feed of silage to good producing cows in regions well adapted to grow- 

 ing corn does not exceed five or six tons per cow. The last group of 21 

 farms doubtless exceeded an economical amount for Grafton County 

 with 11,590 pounds per cow. Silage is an excellent feed for dairy cows, 

 but its use in large amounts is often limited on these farms by a lack 

 of suitable conditions for economical production. Where corn can be 

 grown with any reasonable success, some two to four tons of succu- 

 lence per cow should contribute to better feeding. 



EFFECT OF FIVE SELECTED FACTORS ON LABOR INCOME 



An average of more than 50 ]ier cent of the total receipts on tlie 

 Grafton County farms enumerated in tliis survey came from milk. Con- 

 tributing so largely to the salable products of these businesses, milk 

 represented the outstandingly important enterprise. Therefore, the 

 cost of producing it had a most important influence on the financial 

 success of the business. This relationsliip has been previously shown 

 in tabulations with labor income. In Table 88 milk cost has been asso- 

 ciated with milk price and witli factors of size, efficiency and produc- 

 tion in the farm business to indicate some of the combined effects of 

 all five factors on labor income. The method of selecting farms has 

 been to require that the factors be as good as average. This means 

 average or below for cost of production and average or above for other
