SMion Tests with Feeds for Dairy Cows. 



423 



It ■will be seen that almost identical quantities of milk and fat 

 were produced by tbe two lots of cows, the excess of milk being 

 in favor of prairie hay, and the excess of fat in favor of timothy. 

 From this we conclude that upland prairie hay of good quality is 

 iiilly as valuable for feeding dairy cows as a good grade of timothy 

 hay. 

 » 650. Japan clover hay versus Bermuda hay. — In an experiment 

 with sixty cows conducted at the Mississippi Station > by Lloyd, 

 half were fed mixed hay (Japan clover and some chicken corn) and 

 the other half Bermuda hay. Cotton seed, cotton-seed meal or 

 corn meal was fed in connection with the hay. The mixed hay was 

 valued at $7 and the Bermuda hay at $10 per ton. The experi- 

 ment was continued about twelve weeks. The average results 

 obtained per cow daily were a>s follows, the yield of fat given in 

 the table being calculated from the yield of butter by multiplying 

 by .82, the percentage of pure fat contained:

Bermuda hay produced somewhat more milk and slightly more 

 fat than did the Japan clover hay. At the prices charged the 

 mixed hay was the cheaper; at equal prices there would be little 

 difference in cost of products. (296) 



651. Timothy hay versus meadow fox-tail hay. — An experiment 

 was conducted at Mustiala (Finland) Agricultural College* for 

 the purpose of obtaining data concerning the relative value of 

 timothy and meadow fox-tail {Alopecurus) hay for milk and butter 

 production. The cows received similar quantities of both kinds 

 of hay, ranging from 11.7 to 17.6 pounds per head per day, and 

 oat straw ad libitum. The same amount of concentrates and roots
