Small-tailed Han sheep is a fine-grained, dual-use sheep breed in China. The provenances are mainly distributed in Shandong and Henan provinces, and they are hailed as "Chinese national treasures" and "world rare sheep" by industry experts. Small Tail Han sheep has the characteristics of strong adaptability, resistance to rough feeding, large body size, weight of adult ram 150-200 kg, multiple litters, 2 to 4 lambs per litter, and high feeding efficiency. In recent years, introductions have been made in many places in China, and the benefit of raising has been remarkable. The scientific and technical personnel of the farms of the Liangshan County Agricultural Research Institute in Shandong Province have developed a new method of feeding small tailed sheep, gastric lavage and fertilizer. It is not only convenient, practical, and economical, but also can speed up the growth of small tail Han sheep and reduce the cost of rearing. . First, gastric lavage small tail Han sheep in the feeding is difficult to avoid drinking "dirty" food "scale", prone to parasitic disease, diarrhea or other diseases, affecting their normal growth, and even lead to death. Therefore, the small tailed sheep wash once every time the stomach can achieve the purpose of preventing disease and promoting its healthy growth. The method is: to allow small tail Han sheep to eat enough amount of salt, each time each sheep is fed 0.2 to 0.4 kg, 2 to 3 hours after the sheep appears physiological thirst, give it a sufficient amount of gastric lavage water (point temperature Water or cold water). In the process of gastric lavage, the following points need attention: 1 The time for feeding salt should be selected in the morning when the sheep is fasting. 2 Sick sheep do not have gastric lavage to prevent injury to the stomach, spleen and kidneys. 3 The amount of water for gastric lavage should be sufficient. Each sheep should be no less than 10 kilograms. To make the sheep drink more, sprinkle some wheat bran, corn flour, or other concentrates in the water. 4 In the trial, some farmers were in trouble and simply dissolved the salt directly in the water to lavage the sheep. The effect was not stable and was not advocated. 5 After 15 to 20 minutes, the sheep dredged their slaughter activities to accelerate the blood circulation and increase the excretion, so as to achieve the purpose of disease prevention and health. Second, the small-tailed Han sheep used for breeding by Hefei must maintain its Reproductive System function intact. When the sheep's body is too fat, too much muscle will cause hoop pressure, which is not conducive to the discharge of eggs, pregnancy and implantation. When the sheep body is too thin, it is not conducive to the development of the baby and the formation of aberrant fertilizer is not conducive to the development of the baby. Or birth stillbirth, reduce the reproduction rate. Therefore, the sheep body should be kept properly fat. The method is: the ewes lamb rapidly 45 days after the fattening for 15 days, after the sharp reduction of concentrate feed, sudden increase in roughage, so that the ewes drink more water, reduce nutrition, promote the ewes appear "counter-reverse" phenomenon, thereby increasing Reproduction rate. In the fertilizer application process, the following points need to be noted: 1 During the fertilizer season, it should be selected in spring, summer and autumn. 2 Suitable fertilizer time should not be too long, one week is appropriate. 3 Do not choose diseased, weak, disabled, or bad sheep for fertilization.
