1. Lamb's foster ewes have one child with multiple lambs (or the ewes' accidental death after childbirth). A litter of lambs with a large number of litters can be distributed to foster ewes with few litters. When foster lambs are fostered, in order to ensure the success of fostering, it is generally required that the date of delivery of the two ewes is relatively close, the difference time should be within 3 to 5 days, and the individual body weight of the two litter lambs should not be too different. In addition, the ewe's sense of smell is relatively sensitive (especially the local ewe). To avoid the ewe smelling the odor of foster lambs, breastfeeding is generally refused. In general, lambs are fostered and promoted at night, and two lambs are sprayed with stinky water at the same time before fostering. Either use the same drug as alcohol or other odor, or use a milk and urine of foster ewes to smear the foster lamb, and then put the two litter lambs together in a basket for 30 to 60 minutes so that the foster ewes can't smell and smell. True or false, so as to achieve the purpose of fostering. 2. There are too many lambs in batches to suckle and breastfeed. Over the number of hens in the ewes, the lambs can be divided into two groups and breast-feeding in turn. When batch feeding methods are used, feeding and management of nursing ewes must be strengthened to ensure that the ewes have a moderate level of nutrition, so that the ewes have sufficient milk to feed the lambs. For the grouping of lambs should be reasonably distributed according to size, strength, and at the same time, do a good job of feeding the lamb's early complementing materials, to ease the ewes' breastfeeding burden as much as possible to ensure the balanced development of the whole lamb lamb. 3. Feeding artificial milk For ewes with a large number of litters and lack of milk after ewes are lambing, we should try to provide short-term supplementary feeding on the premise of ensuring that the lambs have been fed primary milk. Short-term supplementary feeding can usually use 20% milk, 10% white sugar, plus 70% water dilute, boiled and then cooled to about 37 °C instead of goat milk to the lamb supplement; can also be used in rice flour plus sugar or milk instead of goat milk feeding lamb. For young lambs of young age and weak constitution, the artificial milk can be fed directly with milk bottles in the short term. If more lambs need to be fed artificial milk, artificial lambs should be trained to suck artificial milk. The method for training the lamb to suck artificial milk is: put the prepared artificial milk in the small milk pot (the height of the bowl is 8 to 10 cm), and use a clean finger to replace the teat to contact the milking surface to educate the lambs on the surface of the milk, usually after 2 to 3 days In training, the lamb will eat on its own in the milk pot. The above method for artificial milk sucking by lambs is relatively simple, and the formula is monotonous and nutrition is not comprehensive. It is only suitable for short-term use when a few lambs or ewes have insufficient milk. If there is a large number of lambs that are artificially fed and the feeding time is long, a scientific artificial milk formula should be used to ensure the normal growth and development of the lambs. 20 days after the birth of the lamb can be used 50% wheat flour, fried soybean powder 17%, skim milk powder 10%, yeast 4%, sugar 4.5%, calcium powder 1.5%, salt 0.5%, trace element additive 0.5% (the formula can refer As follows: 0.8 g of copper sulfate, 2 g of zinc sulfate, 0.8 g of potassium iodide, 0.4 g of manganese sulfate, 2 g of ferrous sulfate, 1.2 g of cobalt chloride, 1 to 2 drops of cod liver oil, and 5 to 8 times of fresh water, stir well, and boil After cooling to 37 °C or so instead of milk feeding lambs. Lamb day after age available corn flour 35%, wheat flour 25%, bean cake powder 15%, fish meal 12%, bran 7%, yeast 3%, calcium powder 2%, salt 0.5%, trace element additive 0.5%, after mixing Add water to stir the lambs (the amount of water should gradually increase from less to less, so that the transition to feed for the lamb).
