90 FEEDING WITH SUGAR BEETS, SUGAR, ETC. 



We conclude that from 19.5 Ibs. milk there was made 1 Ib. 

 butter worth 18. 3c. per Ib. 



From February 2nd to 22nd the cows fed on beets gave 1.056 

 Ibs. milk, those on potatoes during same period 581 Ibs. milk. 

 If we admit the foregoing averages, there would be extracted 

 51 Ibs. butter from beet milk worth $10.00, from the potato 

 milk 30 Ibs. butter worth $5.50, or $4.50 in favor of beets, dur- 

 ing a period of 20 days. To these profits must be added the 

 cream and buttermilk, which with beets is nearly double that 

 obtained from potatoes. 



It would be interesting to determine the comparative fertiliz- 

 ing value of the manure from cows fed upon potatoes and beets. 

 One fact appears to us certain, that 50 Ibs. beets at $4.00 per 

 ton are always cheaper than 40 Ibs. potatoes, even at the same 

 market price, and admitting that the butter returns would be 

 the same (?). Beet butter has its own characteristic color, and 

 will keep for months, while potato butter has no keeping quali- 

 ties and is colorless. 



It has been concluded that high-grade butter cannot be made 

 when cows eat more than 10 Ibs. potatoes per diem. When cows 

 are eating 20 Ibs. beets per diem no coloring matter need be used 

 and the resulting butter is of a superior quality and has a most 

 excellent flavor while potato butter lacks flavor. These feeding 

 experiments were conducted with considerable care, the ration 

 being gradually increased, and then decreased. An important 

 fact noticed was, that cows will continue to eat 50 Ibs. beets 

 with relish, but after a time refuse the 40 Ibs. potatoes. 



Other experiments have been made to determine the value of 



Other experj- potatoes and roots for fattening lambs.* The test was made 



ments ' with 36 lambs divided into 3 lots of 12 each. The three lots 



consumed about the same quantity of grain, hay and roots. 



The table herewith shows the result of these tests:
