If you have prepared a lambing jug (an area where you can separate the ewe and her lamb(s) from the rest of the flock to allow them to bond and to keep them under observation for a couple of days), wait until the lambs have nursed before you move them and their mom into the jug. To move the lambs, hold them in front of you so that the ewe can see them. Back slowly into the lambing jug, making sure that she follows you. If she won't follow you, put the lambs down and give her more time. First-time moms may be overwhelmed by all that is happening and may not readily follow the lambs. If you stress her too much, she might abandon the lambs.It is very important that all lambs suckle immediately after birth to ensure that it receives colostrum (see below). If the lamb is weak, or rejected by the ewe, help it to suckle; or milk out the ewe and get the lamb to drink colostrum from a bottle.
Let the ewe care for her lambs and try not to interfere. It is tempting to want to help and to make a fuss over the new lambs, but it is most important that the ewe bond with her lambs, and this is best done without your help.
The next day or so, record the weight of lamb, and any other relevant information for accurate record keeping.
Colostrum is the milk
produced by the ewe during the first 36 to 48 hours after lambing and is
required for several reasons:
The amount of colostrum a lamb needs depends mainly on how much fuel it requires for heat production. During bad weather (cold, wind, or rain,) the lamb must produce more heat to avoid hypothermia, and colostrum requirements increase. Lambs born in weather range 32-50 degrees F (with wind and rain) need about 95 cc of colostrum per pound of body weight during the first 18 hours. Lambs born in housed conditions 32-50 degrees F (still, dry air) require about 80 cc of colostrum per pound of body weight. Therefore, during the first 18 hours of its life, a 5-lb blackbelly lamb needs 475 cc (15 oz) of colostrum in cold weather and 400 cc (13.5 oz) in mild weather.
Note: When feeding lambs with a stomach tube, a rule of thumb is to feed no more than 20 cc per pound of body weight. This is roughly 3.5 oz per feeding for a 5 lb lamb.
