What are the methods for dealing with lambs when the ewe has insufficient milk?

Fostering lambs. When a ewe gives birth to multiple lambs in one litter (or the ewe dies unexpectedly after giving birth), some of the lambs from the larger litter can be given to a ewe with fewer lambs to raise. To ensure successful fostering, the two ewes are generally required to have lambed within 5 days of each other, and the individual body weights of the two litters of lambs should not differ too greatly. Fostering lambs should be done at night; before fostering, spray both litters of lambs with medicated liquid or alcohol, or smear them with the milk or urine of the foster ewe.

Split feeding. If the number of suckling lambs exceeds the number of the ewe's teats, the lambs can be divided into two groups and fed in turn, grouping the lambs by size and strength. During split feeding, the feeding and management of the suckling ewe must be strengthened to ensure the ewe maintains an above-average nutritional level so that she has sufficient milk. Early work of supplementing grass and introducing feed to the suckling lambs should also be done well, to reduce the ewe's suckling burden as much as possible and ensure balanced growth of the whole litter of lambs.

Feeding artificial milk. On the premise of ensuring the lambs receive colostrum, a short-term supplementary feeding solution is usually to use two parts milk, one part white sugar, and add seven parts water to dilute, boil, then cool to about 37 degC to replace ewe's milk for supplementing the lambs; rice soup with white sugar or soy milk with white sugar can also be used instead of ewe's milk to feed the lambs. The artificial milk prepared by the above methods is not comprehensive in nutrition and is only suitable for short-term use with a small number of lambs or when the ewe's milk is insufficient. If there are many lambs and the supplementary feeding period is long, a scientific artificial milk formula should be used. Before 20 days of age, lambs can be fed wheat flour 50%, roasted soybean flour 17%, corn flour 12%, skimmed milk powder 10%, yeast 4%, white sugar 4.5%, calcium powder 1.5%, salt 0.5%, trace element additive 0.5%, cod liver oil 1 drop to 2 drops, with 5 to 8 times clean water added and stirred evenly, boiled, then cooled to about 37 degC to replace milk for feeding the lambs. After 20 days of age, lambs can be fed corn flour 35%, wheat flour 25%, soybean cake flour 15%, fish meal 12%, wheat bran 7%, yeast 3%, calcium powder 2%, salt 0.5%, trace element additive 0.5%, mixed and stirred with water to feed the lambs, with the amount of water gradually going from more to less, slowly transitioning to feeding the lambs with dry feed.
