PIGGERIES

should be confined to the yards. The interior of the whole building 

 should be limewashed at least twice a year, and the pens should at 

 frequent intervals be washed out with Jeyes' fluid or a suitable dip to 

 keep fleas, lice, etc., under control. 



Avoidance of extremes of temperature. — This depends largely on the 

 materials of construction employed. A good building from this point 

 of view would be one with walls of brick or stone and a thatched roof, 

 though a roof of this description somewhat increases risk of fire, and may 

 harbour insects. Galvanised iron is a bad heat insulator, being too hot 

 in summer and too cold in winter. If a galvanised iron roof be used, it 

 should not be placed too low, as a low iron roof exaggerates the effects of 

 extremes of temperature.

DESIGN No. 2. 



Fig. 156b. — Large brick piggery. 



Space Required. — A space of from 80 to 100 square feet should be 

 allowed in a covered pen for a sow and litter, or for about six young pigs. 

 The open yard in connection with the pen should be about half as large 

 again. In the designs given (1 and 2) the pens with the large open yards 

 at the food-room end of the buildings may be used for a larger number of 

 fattening pigs. 



The Site. — A naturally dry, gently sloping site should preferably be 

 chosen for the piggery. 



The Walls. — The walls should be built preferably of brick or stone ; 

 corrugated iron is too hot in summer and too cold in winter. In design 

 No. 1 the walls are 9-inch, and in design No. 2, 9-inch and 14-inch brick 

 walls. If of stone, the principal walls may be made 18 inches thick, 

 and the partition walls 15 inches thick. They may, for the sake of 

 cheapness, be built of sun-dried bricks, in which case they had better 

 be a brick and a half, or 14 inches thick, and should be protected on 

 their inside surfaces from the grubbing habits of the pigs. This protection
