50 to 60 days old or around 40 to 45 pounds.
Early Weaning. Early weaning is a relative term, but implies weaning at any time after 14 days of age, but usually before 90 days. Sixty (60) days is a common weaning age in intensively managed sheep operations. It is common to wean lambs in a dairy sheep operation when they are 30 to 35 days of age. Artificially-reared lambs can be successfully weaned from a milk diet at 25 to 30 pounds body weight or when they are 30 to 45 days old. Weaning abruptly is better than offering a diluted milk replacer the last week. However, orphan lambs should not be weaned unless they are drinking water and consuming solid food. Wean on weight and not age. 1  To avoid any growth check at weaning, don’t wean until the lambs are at least 20kg liveweight. 2  At this weight, they should be efficient ruminants and be able to grow at about 150-200g/day, which is desirable. 3  Think of this as a minimum weekly gain of 1kg - 1.4kg. 4  Mating your hoggets should be an objective for extra ... 1 To avoid any growth check at weaning, don’t wean until the lambs are at least 20kg liveweight. 2  At this weight, they should be efficient ruminants and be able to grow at about 150-200g/day, which is desirable. 3  Think of this as a minimum weekly gain of 1kg - 1.4kg Early weaning should always be the goal with artificially reared lambs.

Weaning is done around 50 to 60 days old or around 40 to 45 pounds. If you have lambs that are on a bottle they should be weaned as soon as possible because they cost more to feed then the weight they gain on bottles. The lambs should have access to feed in order to get their rumen ready for solid food. Before weaning you should make sure that the lamb is eating enough solid food through creep feeding. Creep feed should be about 15% crude protein and may contain molasses in order to make it more palatable. On the other hand, some producers prefer a natural weaning method where lambs stay on pasture with their mothers until they are four to six months old. This greatly decreases the stress of weaning for both the ewes and lambs, but can also mean lower weight gains in lambs. When weaning, producers should prepare the ewes several days prior to the planned weaning date. Early weaning generally takes place when lambs are 60 days old. Lambs should weigh at least 45 pounds at this time. Most ewes peak in their milk production around three to four weeks after the lambs are born. After that point, milk production decreases rapidly. This greatly decreases the stress of weaning for both the ewes and lambs, but can also mean lower weight gains in lambs. When weaning, producers should prepare the ewes several days prior to the planned weaning date. Keep the lambs on the same feed before and after weaning until the stress of weaning has pasted (7-10 days). Feeds containing urea should not be fed for at least 2 weeks past weaning. Lambs weaned at 10 weeks of age will recognize and return to their dams after 2 months of separation. Artificially-reared lambs can be successfully weaned from a milk diet at 25 to 30 pounds body weight or when they are 30 to 45 days old. Weaning abruptly is better than offering a diluted milk replacer the last week. However, orphan lambs should not be weaned unless they are drinking water and consuming solid food. It is recommended that lambs receive 10 percent of the body weight in colostrum by 24 hours after birth. This means that a 10 lb. lamb should consume 1 lb. (16 ounces) of colostrum by 24 hours of age. Ideally, they should consume half of this within 4 to 8 hours of birth.  Weaning practices should start at least two weeks prior to the actual weaning process. By weaning, I am talking about separating the ewes from their lambs. Lambs should be started on some sort of solid feed at least two weeks before weaning so that they are adapted to living on their own. In addition, lambs should also be accustomed to drinking water. Solid feed often comes in the form of a high protein grain mix, but could also mean highly palatable and high protein hay. This greatly decreases the stress of weaning for both the ewes and lambs, but can also mean lower weight gains in lambs. When weaning, producers should prepare the ewes several days prior to the planned weaning date.
