causes bloat. Though stock may not at first take readily to this crop, 

 they will become accustomed to it if fed no other forage or roughage for 

 a few days. Cattle often crave some dry roughage, while being pastured 

 on this crop on account of its succulent nature. The amount of pastur- 

 age secured from sweet clover during late July and August, when Ken- 

 tucky blue grass or June-grass is in the resting stage, is very satisfac- 

 tory. 



During the summer of 1921 the Farm Crops and Dairy Sections of 

 this Station co-operated in conducting a feeding trial of biennial white 

 sweet clover as a pasture crop. The cows received approximately one 

 pound of grain for each four pounds of milk produced and were on 

 pasture continuously except while being milked or weighed. 



They received no silage or other roughage except that secured from 

 the sweet clover pasture. Sixty-nine dollars worth of milk, at 20 cents 

 per gallon, was produced from one acre of sweet clover after deducting 

 the cost of grain at the rate of $40.00 per ton. With butter fat at 40 

 cents per pound, the cows produced .f2G.02 worth of fat per acre of 

 sweet clover after the cost of the grain was deducted.

A HIGH I'ROTEIX HAY CROP. 



The stage of growth at which sweet clover is cut for hay influences 

 very greatly the quality of hay secured. (See harvesting for hay, page 

 40(K ) When cut at the proper stage it contains practically as much di- 

 gestible protein as alfalfa and more than red clover and the quality 

 and quantity of milk produced when the hay is fed to cows are approxi- 

 mately the same as when other legumes are used (1).* The total yield
