When farrowing time comes the last of February or the first of March in the northern sections of the country, the sows and the young pigs will be better off in a good weather-tight house, such as the one shown above. This is the sort of farrowing house that keeps the young pigs warm and free from cold draughts that quickly end their lives. Besides, it has a system of ventilation that admits fresh air without drafts and prevents condensation that quickly coats the walls with water and frost.
