SHELTER FOR SWINE 257 



day. These are built in the form of a right angle to have 

 them compact and not take too much room and still have 

 sufficient length. They are of the same length to have the 

 conditions the same in all for experimental purposes. W 

 represents smaller lots used for mature herd boars. This 

 arrangement is not absolute but may be modified to suit 

 circumstances and convenience. 



Use of the Hog House. — The use to which such a house 

 may be put is general. Its primary use is for farrowing 

 purposes. The pens are so arranged that this part of the 

 swine industry may be carried on to the best advantage. 

 Between the farrowing seasons, this house may be used 

 for feeding purposes provided it is not used at all times 

 for farrowing purposes. A house of this character then 

 will answer the purpose for producing pure bred hogs for 

 breeding purposes, as well as for producing market hogs. 

 If the breeding herd is large, or if the hog house is small, 

 the herd may be divided so that the pigs are not all far- 

 rowed at the same time. As previously outlined, it is 

 desirable to have all the pigs of a given season farrowed 

 as nearly as possible at the same time. The reason for 

 this is that the pigs may be fed to the best advantage be- 

 cause as they get older and heavier they require varying 

 quantities of nutrients. Also if the pigs are farrowed at 

 the same time, they will be more nearly the same size and 

 will sell to better advantage. Thus if the building is not 

 large enough to accommodate all the sows at one time, 

 the breeding herd may be divided. The spring crop may 

 be allowed to farrow, as for instance, in February and 

 April, and the fall crop in August and October. With 

 such an arrangement the house will be in use the greater 

 part of the year for farrowing purposes, and in such a 

 case the feeding will necessarily have to be done at some 

 other place.
