Unlike most other farm animals, sheep are seasonal breeders and lamb in the spring months when the weather is warming and ample supplies of grass are available. Sheep can be housed for lambing or are more commonly brought to a field close to the farmyard where the shepherd can keep an eye on them. We illustrate the process of lambing.
The
first sign of lambing comes when the ewe leaves the rest of the flock
and finds a quiet location in which to lamb. Within an hour or so, labour
will start.
When
the ewe is in labour she may stand and paw the ground searching for
a lamb in the hope that her efforts have been productive.
Lambs
are normally born head first with the front feet tucked up under the
chin. Sheep generally lamb freely without intervention, but periodically
a lamb may be breached in the womb or otherwise displaced and the ewe
may require assistance from the shepherd.
The
moment of birth. Once the head and shoulders are through the rest of
the lamb is pushed out very quickly.
At
birth lambs are often born with mucus membranes covering their faces.
The ewe will instinctively clear this by licking the newborn lamb. If
the shepherd is nearby he will assist by removing the membranes and
placing the lamb in front of the ewe.
Licking
will continue for some minutes and during this time the lamb will be
gaining strength and starting to think about milk!
After
the first lamb, the second quickly follows. Some breeds of sheep have
only one lamb. This is a survival mechanism for sheep that live in cold
hilly conditions where ewes may have insufficient milk for two lambs
and where hypothermia can quickly kill.
In
just fifteen minutes both lambs have been born. After birth the "after
birth" will follow. This is the mucal membrane that contained the lambs
within the womb. Part of this can be seen trailing from the rear of
the ewe. Sometimes the ewe will eat her own afterbirth.
The
urge to suck is very strong in the new born lamb and within 20 minutes
the lamb will be looking for milk. The shepherd may assist the lamb
if it is struggling to find the ewe's teat.
The
first few days of milk contain "colostrum". This is a very thick form
of milk that is produced only at birth by the ewe. It contains many
beneficial antibodies that help prevent the lamb from becoming ill.
Some lambs are not so lucky however. The ewe may reject the lamb or
sometimes simply have insufficient milk to feed it. Lambs in this situation
become orphans and are looked after directly by the shepherd.
