Generally speaking, some shelter of a temporary character was provided failing that furnished by trees, and straw stacks, etc., but our American cousins have gone one better in that they have introduced small movable houses which can be transported on wheels and can be utilised for a sow and her pigs, or for a number of stores. In the former course, an enclosure sufficiently large for the sow to graze therein is fenced in so that each sow can be kept separate until the pigs are old enough to prevent others from robbing them of their birthright. The chief difficulty attending this system is not experienced in the United States to the extent it is in this country, since the general custom there is to allow each sow to farrow a litter of pigs in the spring and then to fatten off both sow and pigs, save those reserved for breeding purposes next year. This plan, which appears to be wasteful, also handicaps the owner who desires to improve his pig stock, since an opportunity is denied him of discovering the best of his sows and so reserving them and their produce to form the nucleus of a really good herd. The system is not an entirely new one, as it is practised to a great extent in some parts of Lincolnshire and other Northern counties, where there is not the excuse made for it in the States that it avoids the trouble and risk from the intense cold attending the farrowing of sows in the winter. It may be that the severity of our winters is not usually great, but the cold, damp and foggy weather commonly experienced in England during the last two or three months of the year render it necessary to warmly house young pigs, and this is difficult in wooden houses of limited size, as these become hot and stuffy when entirely closed, or damp and cold when unclosed. Again, the labour attending the feeding of a large herd housed in isolated sties must be very considerable. Another objection raised against this farrowing of sows in these small houses is that it is difficult if not impossible at night to have the pigman in attendance on the sow, further, that it is not advisable to allow the young pigs to roam about with their dam until they are some weeks old, as when the weather is cold or wet they become chilled and when the sun is hot they quickly become blistered, both conditions materially interfering with their well doing.
