Keep sows cycling
A reader asks:
What do you recommend to keep
sows cycling properly in order to
keep group farrowing schedules
running smoothly’
Dr. Trayer comments:
One of the major problems in
total confinement operations is the
continuing active cycling of
breeding stock after the weaning
period.
We often find individual
problems in herds that can he
identified as management
problems and corrected.
And, we do know a three week
wean puts more pressure on the
individual sow as far as getting the

week wean, that is waiting four
weeks before weaning the sow.
My general recommendations in
any intensified farrowing
operation is that every objective
should be made in the farrowing
room to keep the animal in as good
physical shape as possible If she
has farrowing problems, correct
them and get them under control
before she is brought back into the
breeding area
If she has MMA problems, a
discharge, if she is low in body
weight, increase her feed so she is
consuming all she will eat and is
putting on weight. If she is a thin
sow and has a small litter, you may

consider transferring the pigs to
another sow, weaning the sow
early, and giving her extra feed in
the farrowing area or gestation
area so she can rejoin the group at
a later tune in good body condition.
My philosophy in weaning is
enough stress to bring an animal
into a good heat cycle three to five
days after weaning. It has been
questioned but not proven that a
three week wean is possibly too
early for the reproductive cycle of
the sow.
Other methods used to make
animals cycle include hormone
shots, not the ideal situation.

the carcasses examined for
