From this we see that from 343^ gallons of Shorthorn and of 

 Jersey milk, 125 lb. and 180^ lb. of butter were respectively 

 obtained. In the latter case 55 lb. more butter is obtained 

 than in the former, or an increase of 44 per cent. On the face 

 of it, therefore, it would appear that the Jersey is by far the more 

 profitable cow to keep for butter-making, and this is a point 

 which merits close attention. The following table shows the 

 average live weight, the milk yield, the butter ratio, and the 

 yield of butter for both breeds of cows during the period of the 

 experiment : —

The yield of butter per cow is a calculated figure, and it is 

 obtained by assuming that the average yield would in each case 

 show the average butter ratio. We see. then, that the return in 

 butter from the Jerseys is no less than 29 lb. per cow greater 

 than that from the Shorthorns, and since three Jerseys can be 

 kept on as much ground as two Shorthorns, the keeping of the 

 former breed would appear to be a most profitable undertaking. 

 Each Shorthorn would undoubtedly consume more food to pro- 

 duce 233 lb. of butter than would each Jersey to produce 

 262 lb. It vras stated at the outset that in the feeding of the 

 cattle we worked on the assumption that the Shorthorns were 

 half as heavy again as the Jerseys. As a matter of fact they 

 were more than 50 per cent, heavier. In any case they received
