HATCH EXPERIMENT STATION. 



[Jan. 



much depends upon the cost of feeds used, character of the 

 cows, and the stage of lactation. The figures simply show 

 what six of the better class of ordinary cows that had l)een 

 well fed were able to do, during the first six months after 

 calving. 



Table III. — Yield and Cost of Butter from Poorest and Best 



Cows. 



In Experiment I. the best cow on the narrow ration pro- 

 duced 12.2 pounds of butter per week, at a cost for feed 

 consumed of 14 cents per pound ; while the poorest cow pro- 

 duced 8.26 pounds, at a cost of 19.37 cents per pound. In 

 the same experiment on the wide ration one cow produced 

 9.52 pounds per week, costing 1G.67 cents per pound; and 

 another 7.28 pounds per week, costing 18.88 cents. 



In Experiment II. the best yield with the narrow ration 

 was 12.81 pounds of butter per week, costing for feed eaten 

 11.66 cents per pound ; and the poorest yield w^as 7.98 

 pounds, costing 15.90 cents. In the same experiment on 

 the wide ration the best yield was 10.92 pounds weekly, 

 costing 12.71 cents per pound; and the least yield 6.86 

 pounds weekly, costing 16.21 cents per pound. One is 

 enabled from the above figures to note both the influence of 

 the cow and the cost of the daily ration upon the cost of the 

 butter produced. The cow yielding 12.81 pounds weekly, 

 at a cost of 11.66 cents per pound for food consumed, was a 

 grade Guernsey, fresh at the time. Her general form and 

 appearance would not indicate that she was more than a very 

 ordinary cow. She produced al)out 14 (juarts of milk daily 

 when at her best, containing 5.8 per cent, of ])utter fat. 

 Such facts as the above ought certainly to stimulate farmers 

 to ascertain the amount and (juality of the milk produced by
