Feeds and Feeding. 



economical gains than do yearling wethers. Owing to their tendency 

 to grow, lambs require a longer period to fatten than do mature 

 wethers, and their ration should contain more fat-producing ma- 

 terial. (95, 815) 



733. Exercise v. confinement. At the Wisconsin Station 1 Hum- 

 phrey and Kleinheinz tested the influence of exercise and close con- 

 finement on fattening wether lambs during 3 consecutive winters. 

 In each trial 2 lots of 12 lambs each were fed the same rations. One 

 lot was closely confined and the other received exercise daily when 

 the weather permitted. The results of the 3 trials are averaged 

 below : 



Exercise v. confinement for fattening wether lambs. 



These lambs made neither large nor economical gains, as they were 

 not fed to produce the largest gains, and all were in better condi- 

 tion at the beginning than average feeding lambs. These results 

 indicate that, in fattening growing wethers, close confinement in 

 dry, airy, well-lighted pens is better than allowing much ex- 

 ercise. (495, 771) 



734. Exposure v. confinement. Next to feed, the feeding place 

 and the method of confinement are of importance in fattening sheep. 

 At the Minnesota Station 2 Shaw fed 4 lots, each of 8 lambs averaging 

 78 Ibs., for 117 days under various conditions as to confinement. Lot 

 I was kept out of doors continuously in a yard sheltered from the 

 wind by a low building at one side. Lot II was confined in a yard 

 with an open shed for shelter. Lot III was kept in a compartment of 

 the barn having one large window facing the east for ventilation. All 

 lots were fed the same ration with the following results :
