58. Areas of high rainfall should be avoided, particularly where poor drainage is also a consideration. Sites exposed to high wind and where long periods of extreme cold, frost and snow might be expected are also unsuitable.
59. During winter months, shelters should be well-bedded and draught-free. Sheltering the doorways by siting the huts with their backs to the prevailing wind, and perhaps by the use of plastic flaps over the doorways, is necessary to minimise the possibility of bedding becoming wet through seepage or driven rain or snow.
60. During summer months, farrowing huts should be insulated and effectively ventilated and water must be easily accessible.
61. Shelters should be of sufficient weight, or effectively secured to the ground, to prevent movement by wind or by sows.
62. Wallows containing a suitable, muddy material should be provided, particularly for dry sows, throughout periods of hot weather.
63. Those responsible for the keeping of pigs outdoors should familiarise themselves with the MAFF Publication Heat Stress In Pigs - Solving the Problem.
