84 AGRICULTURAL EXPERIMENT STATION. [Jan. 



fore, after the manner of the one previously described, must 

 be conducted with a large number of sheep, in order to 

 eliminate as far as possible this source of error, and furnish 

 data that will throw more definite light upon the subject. 

 It is held by many who have good grounds upon which to 

 base their belief that rations with a ratio of 1 : 4 can be 

 economically fed. 



OBJECT II. TO SEE IF LIVE WEIGHT COULD NOT 

 BE PRODUCED CHEAPER BY SUBSTITUTING- CORN 

 AND SOJA-BEAN ENSILAGE TO A CONSIDERABLE 

 EXTENT FOR ROWEN. 



Feeding Period I. The six sheep used in the experiment 

 were fed for seven weeks upon Buffalo gluten feed, cotton- 

 seed meal and rowen. 



Feeding Period II. In this period corn and soja-bean 

 ensilage was substituted for the larger part of the rowen. 



The following table gives the amounts of the several foods 

 consumed and the total and net cost of the same, as well as 

 the total and net cost of feed required to produce one jiound 

 of live weio:ht.
