Equipment for farm sheep raising, V. O. McWhobter (17. S. Dcpt. Agr., 

 Farmers' Bui. 810 (1917), pp 27, Jigs. 57).— "The object of this publication is 

 to furnish a practical guide for the equipping of farms for sheep raising. Wide 

 differences in climatic conditions render it impracticable to suggest a particular 

 type of building for all sections; therefore a number of types of barns and 

 sheds are presented." 



" Equipment for raising sheep on farms need not be expensive. In mild lati- 

 tudes little housing is needed, and the main need Is for fencing and pastures 

 of sufficient number and size to allow frequent changing of flocks to fresh 

 ground to insure health. Where winters are longer and more severe, buildings 

 and sheds are necessary to furnish protection from storms, though no special 

 provisions are needed for warmth. Dryness, good ventilation, and freedom from 

 drafts are the first requisites of buildings for sheep. Convenience in feeding 

 and shepherding must also be held in mind In locating and planning such 

 buildings or sheds. Small flocks can be cared for In sections of barns having 

 stabling or feed storage for other .stock, but with a flock of, say, 100 ewes sepa- 

 rate buildings are desirable. The interior arrangement of these buildings 

 should be such as to require a minimum of labor and the least possible moving 

 of the ewes in doing the feeding and caring for them during the lambing season. 

 A building of this type can also be utilized for fattening purchased lambs to be 

 disposed of before lambing begins in the regular farm flock. A good supply of 

 feed racks, grain troughs, etc., can be provided at small expense and will 

 save labor and prevent waste of feed." 



Fencing, crates, feed racks, and miscellaneous equipment are also described.
