DAIRY FAHMING— DAIRYING. 



Alfalfa hay v. timothy hay, and alfalfa hay v. bran for dairy cows, W. J. 

 Fraser and C. C. Hayden (Illinois Sta. Bui. 11,6, pp. 131-lU, charts 4).— This 

 bulletin reports two demonstrations, planned to show the value of alfalfa hay 

 in rations for dairy cows. 



In the first, alfalfa was compared with timothy hay in the ordinary ration. 

 The basal ration of 16 cows, divided into 2 lots, for 25 weeks was shredded 

 corn stover and a grain mixture of corn meal and wheat bran 2i : 1. During 

 a preliminary feeding period the cows also received alsike clover and timothy 

 hay. In the main feeding period the reversal method of feeding was followed." 

 The last 4 weeks all cows were fed alfalfa and were pastured for a short time 

 on green rye. The total amount of milk produced by both lots for the 6 weeks 

 during which tbey were fed alfalfa was 18,496 lbs., and for the 6 weeks fed 

 timothy 15,704 lbs. 



"As soon as the hay was changed on lot 1, December 17, from mixed alsike 

 clover and timothy to timothy, there was a sudden drop in the milk flow of 

 about 25 lbs. per cow in 3 weeks, and this flow remained down to a little below 

 the 190-lb. line until the close of the first period, when the hay was changed 

 from timothy to alfalfa. As soon as this change was made there was a rapid 

 rise, during the next 3 weeks, or up to the close of the alfalfa period. When 

 the cows were turned on green rye, April 22, this flow was still maintained, on 

 rye and alfalfa, for the next 4 weeks. . . .
