12 OHIO EXPERIMENT STATION: BULLETIN 187. 



'Pursuing 1 the line of work in experimental fattening of range 

 lambs that was begun in cooperation with Mr. S. J. Fryer, in Nov- 

 ember, 1905, the experiment reported in this bulletin was conducted 

 at Mr. Fryer's farm in Wayne county during the winter of 1906-07. 

 A part of the experiment is, substantially, a duplication of the 

 work of 1905-06. The results of the work of 1906-07 are presented 

 in the first part of this bulletin, after which a summary of the two 

 years' work is given in a condensed form. 



OBJECTS. 



The objects of this experiment were: 



1 To secure additional data on the advisability of feeding a 

 proprietary stock food or linseed oilmeal to fattening range lambs in 

 connection with corn and a nitrogenous roughage (clover in this 

 case). 



2 To compare heavy feeding of grain with moderate feeding of 

 grain. 



3 To compare the rate of gains made by ewe lambs and by 

 wether lambs. 



4 To secure additional data on that subject of great and grow- 

 ing importance, the production of manure by farm animals. 



The experiment of 1905-06 did not deal with the heavy grain 

 ration, nor with the comparative rapidity of gains by ewes and by 

 wethers. In other essentials the two experiments were very similar. 

 In the second experiment only one nitrogenous concentrate- 

 linseed oilmeal was tested, while in the former, both linseed oil- 

 meal and cottonseed meal were tested. During the first experi- 

 ment the roughage consisted of alfalfa, clover and some bluegrass. 

 During the second experiment only clover hay was fed. 



LAMBS USED IN THE EXPERIMENT. 



176 head of lambs in four lots of 44 each were used in this ex- 

 periment. Three of these four lots contained 22 ewes and 22 

 wethers; one lot contained 23 ewes and only 21 wethers. They 

 were selected from a lot of about 350 head of Wyoming-bred 

 lambs, purchased for Mr. Fryer by a Chicago commission firm. 

 They were thrifty and vigorous, but not so growthy as the lambs 

 used in the previous test (see Plate I), apparently carrying a much 

 greater percentage of Merino blood than did the lambs fed in 1905- 

 06. A fair idea of the breeding of the two lots may be gained from 

 the statement that the wool shorn in 1906 graded "one-quarter" to 

 "three-eighths", while that shorn in 1907 graded "medium" as 

 graded by the local buyers. In neither instance were the lambs 

 that were used in the experiment shorn, but other lambs from the 

 same bands that the experimental lambs were selected from were
