At present, all regions are carrying out economical crosses for mutton sheep. The first and most preferred female parent is a local mutton sheep breed. Occasionally, the number of litters per litter exceeds that of ewes. In this case, although it is a good thing for farmers, due to the large number of lambs in the ewes, the relative size of the ewes is smaller and their physique is relatively thin. For example, if the farmer feeds the lambs improperly, management If not, it will cause some of the weaker lambs to eat without milk and starve to death. To improve the survival rate of the ewes and the productive lambs of the ewes, and to increase the economic benefits of raising mutton sheep, the raising sheep farms and sheep farms may adopt the following feeding methods. 1. Lambs are born to the ewes with a single child and a large number of lambs (or ewes died accidentally after delivery). A litter of lambs can be distributed in small portions to ewes with few litters. When using lambs to foster, in order to ensure the success of fostering, it is generally required that the date of delivery of the two ewe be 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 The sense of smell is sensitive (especially local ewes). In order to prevent the ewes from sniffing the odor of foster lambs, they are not allowed to breastfeed. In general, lambs are fostered and promoted at night. Before the fostering, the two litter lambs are simultaneously sprayed with odor or alcohol and the like. The drug, or the foster lamb is used to milk the foster ewes, urine, etc., and then the two litter lambs are put together in baskets for 30 to 60 minutes so that the foster ewes can't distinguish between true and false. The purpose of fostering. 2. There are too many breast-feeding and nursing lambs in batches, which exceeds the number of ewes in the ewes. The lambs can be divided into two groups to breastfeed 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 grouped lambs, they should be reasonably distributed according to size, strength, and strength. At the same time, they should do early work on sucking lambs for suckling lambs to reduce the suckling burden of the ewes as much as possible, and ensure the balanced development of the whole 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 adopt short-term feeding methods on the premise of ensuring that the lambs are fed to the primary milk. Usually 20% milk, 10% white sugar, plus 70% water dilute, boiled and 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 to the bottle in the short term. If more lambs need to be fed artificial milk, artificial training should be performed for the lambs to suck artificial milk. General training The method for sucking artificial milk by the lamb is: put the prepared artificial milk in the small milk pot (the height of the pot is 8 to 10 cm), and use a clean finger to replace the teat to contact the milking surface to educate the lamb on the water surface. Generally, the training is performed for 2 to 3 days. The lamb will feed itself in the milk pot. The preparation method of the artificial milk sucked by the lambs above is relatively simple, and the formulation is monotonous, and the nutrition is not comprehensive, and 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. After 20 days of age, the lamb can use 35% of corn flour, 25% of wheat flour, 15% of bean cake powder, 12% of fish meal, 7% of wheat bran, 3% of yeast, 2% of calcium powder, 0.5% of salt, and 0.5% of trace element additive. 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).
