4. Mode of Feeding. 



The time occupied by the experiment amounted to two 

 hundred and two days ; it was divided into four feeding 

 periods. The first feeding period extended over fourteen 

 days, the second lasted ninety-eight days, the third thirty- 

 four days and the fourth forty-one days. Eight days were ■ 

 usually allowed to pass by between succeeding feeding 

 periods before the results accompanying the changes made 

 in the diet were recorded. Each animal was kept in a sep- 

 arate pen ; all received during the first period the same daily 

 diet. This course was adopted to give each a fair chance in 

 feed, and to bring all animals as far as practicable into a 

 desirable uniform condition for a subsequent comparative test 

 regarding the merits and good economy of different grain 

 feed rations for meat production. They received their feed 

 twice a day. At the close of the first feeding period a 

 division of the lambs into two lots, A and B, each numbering 

 three, was made for the purpose of testing different grain 

 feed rations in connection with the same article of coarse feed. 



The daily grain feed ration during the first feeding period 

 consisted of a mixture of two weight parts of wheat bran 

 and one weight part of old-process linseed meal. Eight 

 ounces of this mixture Avere fed, per head, for every pound 

 of rowen consumed. The amount of the grain feed mixture 

 consumed daily per head varied from twelve to fourteen 

 ounces, and that of rowen from one and one-half pounds to 

 one and three-quarters pounds in case of different animals. 

 Subsequently two different combinations of grain feed were 

 fed to the two lots of lambs (A and B). 



The daily grain feed ration in case of Lot A (1, 2 and 3) 

 consisted of a mixture often weight parts of corn meal, two 

 weight parts of wheat bran and one weight part of Chicago 

 gluten meal. Lot B (4, 5 and 6) received as daily grain 

 feed ration, during the same time, a mixture of two weight 

 parts of wheat bran and one we ight part of Chicago gluten meal . 



Rowen and rowen with corn ensilage furnished alternately 

 for both lots at corresponding periods the coarse feed por- 

 tion of their daily diet. Both lots of lambs received as their 

 daily diet eight ounces of their respective grain feed mixture
