THIRTY-SEVENTH ANNUAL CONVENTION. 165 



approximately 5,000 pounds of milk in a year when fed on the 

 unpalatable and unbalanced ration, inevitably raised under this 

 system. This is not only because the cows would be in poorer 

 physical condition, but because they would consume less of thesa 

 feeds. Cows of this efficiency would produce approximately 

 5,500 pounds of milk in a year when fed on a ration made of 

 feeds raised under system No. 2. It must be borne in mind that 

 in figuring the amount of milk produced per acre under systems 

 No. 1 and No. 2, the cows are in each case charged with only 

 the amount of feed required to produce the less amount of milk, 

 and that the cows are not all fed the same amount of nutrients, 

 regardless of their production. 



All Feed on the Farm — Other Conditions. 



To put the systems on the same basis, all the feed is pro- 

 duced on the farm, and nothing but milk, old cows, and surplus 

 calves are sold. A good pure bred sire is kept and the herd is 

 made self-sustaining by raising enough heifers from the best 

 cows to keep up the milking stock. As cows will produce, on the 

 average, for six years, this means that one-sixth as many heifers 

 must be raised each year as there are cows in the herd. In the 

 calculations that follow it is figured that the feed for one cow, 

 for one year will be sufficient to raise a heifer from birth to 

 freshening at 2.y 2 years of age. 



One-sixth of the cows in the herd are to be sold each year 

 and these would bring an average price of twenty-five dollars. 

 The surplus each, for veal, would number ninety per cent of the 

 cows in the herd minus heifers that must be raised to supply the 

 herd with cows. 



Conclusion. 



Wonders of increased production have been worked on 

 many dairy farms by getting better cows ; and it is here shown 

 that amazing results may also be obtained by following a better 

 system of cropping. It must be remembered that all results in 

 this article are comparative.
