NATIONS FOR FATTENING WESTERN YEARLING SHEEP 



F. B. MUMFORD, E. A. TROWBRIDGE AND H. HACKEDORN. 



The object of this experiment was to secure data concerning the 

 relative value of various rations and under different conditions for fat- 

 tening western yearlings. The results of these trials are grouped to 

 show : 



1. The economy of feeding nitrogenous supplements with 

 shelled corn; 



2. To determine the relative efficiency of clover and timothy 

 hay as roughages; 



3. To study the effect of corn silage when added to a ration 

 of shelled corn and clover hay; 



4. To determine the efficiency of a self-feeder; 



5. To gather data which would throw some light on feeding in 

 an open lot. 



Sheep Used in the Experiment. The 140 yearlings which were 

 used in this experiment were classed as Wyoming yearlings. 

 They were selected from a band of feeding yearlings purchased from 

 Starr Brothers of Boone county. They were in good medium feed- 

 ing condition and all sheep were of good general health. 



The 140 yearlings were selected especially for uniformity of 

 size, quality and condition. They were divided into seven lots of 

 twenty sheep each. These lots were divided uniformly as to size, 

 quality and condition. The following rations were fed: 



Lot I. Shelled corn and timothy hay. 



Lot II. Shelled corn and clover hay. 



Lot III. Six parts shelled corn; one part linseed oil meal (by 

 weight) and clover hay. 



Lot IV. Shelled corn, six parts; cotton-seed meal, one part 

 (by weight) ; and clover hay. 



Lot V. Shelled corn, corn silage and clover hay. 



Lot VI. Shelled corn and clover hay; self feeder. 



Lot VII. Shelled corn and clover hay without shelter. 



All lots excepting Lot VII were fed in the sheep barn in pens 

 6j/2 / x34 / in size. Each pen had doors opening to the south into an 

 exercise lot 6j/2'x61' in size. The sheep had the run of these pens
