THIRTY-SEVENTH ANNUAL CONVENTION. 321 



Feeding each of the five horses needed under this system 13 

 pounds of corn per day for 10^2 months and 15 pounds of clover 

 hay per day for 12 months, it is found that they require 6.65 

 acres of corn, 5.4 acres of clover and 1.25 acres of pasture — 

 13.3 acres in all. When this and the 8 acres in roads and yards 

 are taken from the farm, 138.7 acres are left available for dairy 

 stock — 50.35 acres corn, 19 acres oats, 13.6 acres clover, 19 

 acres alfalfa and 36.75 acres pasture. Cows fed on rations 

 grown in this system should produce their maximum yield, or 

 6000 pounds of milk per year. 



During the summer six months, or 182 days, from May 10 

 to November 10, the cows would have to produce, on the av- 

 erage, 13 pounds of milk per day for 122 days, allowing 60 days 

 to be dry. 



During this time they should receive digestible nutrients 

 as follows:

The pasture must be supplemented with green oats and 

 corn silage from about July 1 to November 10; 70 pounds of 

 green oats per cow per day for 30 days, 40 pounds of silage 

 per cow per day for 125 days, three pounds of corn meal per 

 cow per day for 182 days and six pounds of clover hay per day 

 for 182 days. With this supplementary feed 36.75 acres of pas- 

 ture will support approximately 65 head of cows and allow each 

 animal .57 of an acre of pasture.
