Excerpt: ...influence, but it may be taken as a rule that young pigs are fully able to fend for themselves by the time they are eight weeks old. Should it be possible to allow the pigs to remain on the sow for so long a time as twelve weeks without prejudicing the next litters as to the time of year of their arrival, the pigs may benefit, and no loss of food will be sustained, since it has been clearly proved that pigs beyond the age of eight weeks can be fed quite as economically, if not more so, on the sow than if weaned. It may also be possible to feed the sow on somewhat coarser and less expensive food than could be satisfactorily fed to the young pigs, as her digestive organs would be better able to treat the coarser food. Another advantage generally follows keeping the pigs for a longer time on the sow if the latter be well fed is that she will be in a stronger and better condition to start the building up of her next litter. As a rule young pigs will commence to eat when they are from three to four weeks old. If the sow is fed in the sty in which the little pigs are, these will endeavour to share in the food; at first they may content themselves with licking any food which may be outside the trough, but they quickly show a desire for more, and attempt to get into the trough. When this is evident, it is advisable to feed the little pigs apart from the sow; a low flat trough is best, as one with high sides is said to cause "high Pg 100 backed" pigs, or pigs suffering from a curvature of the spine. If a little milk can be obtained, the pigs will promptly drink it, if the milk be whole they will thrive best, but even if only skim or separated milk be obtainable, or butter milk, providing that it be drawn off ere the salt is put into the churn, a small quantity will be beneficial, but the pigs will not be able to digest so large a quantity of the separated as of the whole milk. The former is apt to have a constipating effect on the bowels of the youngsters....
