The Pig: Breeding, Rearing, and Marketing

We found sharps, or the finest portion of miller's offals (which usually
go by varying names in different parts of the country), the most
suitable food for newly farrowed sows, and until the pigs were at least
four weeks old. Some persons recommend that a portion of the food should
consist of bran, this on two grounds--the first that its use tends to
prevent constipation, and secondly on account of the food analysis which
it gives. Our experience has been that when sharps are fed to the sow no
trouble should arise from constipation, whilst as to the nutriment which
bran contains the claim may be good, but the pig is unable to extract
it; so large a proportion of the bran passes through the pig in an
undigested condition. As a rule the pig, unlike the horse, cow, or
sheep, does not masticate its food, nor does it, like the two last
named, chew its cud, but it usually bolts its food, and thus casts a
greater labour on its digestive organs which have neither the time nor
power to extract the whole of the nutriment from the bran. In addition
to this, bran tends to too great looseness of the bowels, which in the
case of young pigs tends to become diarrhœa.
There is a tendency on the part of some pigmen who are over anxious to
succeed to feed the sow too large a quantity of food during the first
ten days or so after she has farrowed. During this period the demand on
the sow is really not much greater than it was during the last two or
three weeks of carrying the pigs. As the pigs grow older an increased
supply of food is necessary, but for a week or two after the arrival of
the pigs twice feeding of the sow should suffice unless she is very low
in condition, or a very large litter of pigs is left on her. In such
cases it may be advisable to feed her three times per day just as much
as she will promptly clear up. It is a great mistake to give so much
food at one time that a portion is left over in the trough,
particularly is this so when the pigs are over three weeks old, as
nothing so quickly upsets the stomachs of the youngsters as sour food.
If in ordinary cases feeding the sow three times daily is persisted in,
the same quantity of food given should simply be distributed over the
three feedings, as an excess of food is only less a mistake than
underfeeding.
