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 strong adaptability, rough feeding, and large body shape. Adult ram weight 150 to 200 kg, more lambs, 2 to 4 lambs per fetus, feeding efficiency. Features. In recent years, introductions have been made in many places in China, and the benefit of raising has been remarkable. Recently, the scientific and technical personnel of the farms of Liangshan County, 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 accelerate the growth of small tail Han sheep and reduce Feeding costs. Gastrointestinal small-tail Han sheep in the feeding hard to avoid drinking "dirty" food "scale", prone to parasitic diseases, 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 appear physiological thirst, give it a sufficient amount of gastric lavage water, warm water Or cool 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 and spleen. 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 unstable and was not promoted. 5 After 15 to 20 minutes of drinking, the sheep drove its slaughter activities to accelerate the blood circulation and increase the excretion, so as to achieve the purpose of disease prevention and health. The small-tailed sheep that Fertilizer uses to breed 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 The fertilizer season should be selected in spring, summer and autumn. 2 Fertilizer time should not be too long, one week is appropriate. 3 Do not choose diseased, weak, disabled or inferior sheep for the fertilizer-fed objects.
