Small-tailed Han sheep is an excellent local variety that is high-yield, fast-growing, and larger than one body in China. It has been praised as a national treasure by Chinese sheep-raising experts. In the introduction practice of more than two years, I found that it is essential to strengthen the management of breeding sheep at the beginning of introduction, and it has a positive effect on enhancing its adaptability, disease resistance and breeding rate. Preparation before introduction: The sheep is clean and dry, so it is necessary to thoroughly clean the pens and sports fields before the introduction of the sheep, and disinfect the environment with 0.2% potassium permanganate. It is required to ventilate, protect against moisture and shade in the summer, and to protect against cold and wind in winter. Drinking water: The sheep are very tired after long-distance transportation. The sheep should be fully rested first. Don't be shocked. Drink water after it is stable. For the first time, fresh rice soup or thin cornmeal soup is better. Drinking water with unclean water or disparity with body temperature should not be given. Because the sheep are fasting for a long time, the first feeding amount should not be too large, and the high quality forage can be fed to 70% full, so that the gastrointestinal function is fully regulated. Inventory and grouping: take a rest after feeding, check and check the sheep that are cited, and group them according to gender, age and physical condition. For the thinner sheep, 70% cornmeal, 25% biscuits, and 5% bran will be supplemented for a short period of time to restore their constitution as soon as possible. Shearing medicated bath: Shearing sheep with long hair, especially thin sheep. Summer stays should not be too short to prevent mosquito bites. A medicated bath is required 7 to 10 days after shearing. Choose sunny and windless weather, use 0.1% of the trichlorfon solution for 1 to 2 minutes, and the liquid temperature is controlled at about 30 °C. Deworming work can be carried out in batches, according to the structure of the flock, the breeding of the pregnancy and the flexibility of the sheep. For drugs, choose levamisole, sante injection, etc. with a small negative effect. Observation and treatment: Small-tailed Han sheep have strong disease resistance, and the symptoms are not obvious at the beginning of the disease. It is necessary to observe the mental state, diet and exercise of the sheep frequently. If the abnormality occurs slightly, it means that the sheep is sick. The main diseases in the early stage of introduction are keratitis, stomatitis and pneumonia. It is found that the sick sheep should be isolated and treated in time. Feeding transition: If the environmental conditions, feeding methods and feeding levels of the introduced land are relatively different, the transition should be carried out in a gradual and orderly manner so that the sheep can reduce the stimulation as much as possible and quickly adapt to the local environment.
