THE BREEDING OF LIVE STOCK 271 



buildings are not desirable for live stock, for they have suflB- 

 cient covering of hair to keep their bodies warm; but they 

 should be kept dry and protected from the cold rains and 

 chilly winds of winter and spring. 4. Exercise is necessary, 

 especially for breeding animals. Exercise is nature's method 

 of keeping the body vigorous. Animals should be in the open 

 air in summer and be turned out in good weather during 

 the winter. 



Good ventilation is also necessary when animals are stabled. 

 To get such ventilation without having drafts of air over the 

 animals, many stockmen are using muslin tacked over the 

 windows instead of glass in the sash. The muslin permits an 

 exchange of atmosphere but prevents drafts.
