(i) Selection of lamb breeds to make full use of the advantages of hybridization to crossbred local goats with meat from Boer goats or to use meatless roads Setter, Suffolk, Texel, Merino, and Charolais sheep. Offspring produced, the weight of more than 10 kilograms can be selected as fattening lambs. The hybrid lambs are resistant to roughage, strong disease resistance, high reproductive rate, high growth rate of the parent sheep, and good meat quality. Due to the high utilization rate of feed, it can reach 50 kg after 7 months of age. (b) Lamb breast-feeding is best cultivated using a self-cultivation and self-fertility one-stop rapid fattening method. In order to avoid introduction, purchase and other adverse environmental impact. 1. Feed colostrum on time: The lamb should be fed colostrum as soon as possible within 2 to 3 hours after birth. Because colostrum is rich in nutrients and easy to absorb, its protein content is 4 times that of conventional milk and contains more antibodies, which not only clears the gastrointestinal tract, but also inhibits the proliferation of bacteria in the digestive tract and enhances the ability of the lamb to resist diseases. . 2. Early make up of fodder: 30 days after the lamb's birth, the ewes' lactation is far from meeting the needs of the lamb. Therefore, the lamb must be eaten early. Generally, 15 to 20 days after birth, lambs should be trained to eat some nutritious, high-quality and easily digestible high-quality feeds such as carrots. After 25 days of age fed with corn, soybean meal, bran and other mixture to promote the development of digestive organs. Each lamb is supplemented with 60 grams of concentrate and 5 grams of salt. 3. Lamb weaning: Lambs must be weaned at 4 months of age. More than one weaning is used, that is, the mother and the lamb are separated, the ewes are driven off, and the lamb is left in the original circle so that the lamb can maintain its original feeding environment. Weaning lambs should be fed 0.3 to 0.4 kilograms of concentrate each day, and 1 to 1.5 kilograms of high-quality hay. After 1 week, supplemental concentrates can be increased to 0.5 kilograms and salt 8 to 10 grams. 4. Deworming: Lambs should be dewormed and stomachic before weaning at 4 months of age. The worms were dewormed with avermectin tablets. The dose of each lamb was 5 milligrams (1 tablet) at intervals of 7 days and then served once; the stomach was treated with artificial salt once orally 5 to 15 grams. (3) Lambs are required to be fed with fattening sheep in winter and cool in summer and dry on the ground. Feed formulation: corn 58%, soybean meal 20%, bran 20%, bone meal 1.5%, salt 0.5%, and with high quality hay, juicy material and green material. The general mixed concentrate and green coarse material ratio is 60:40. Concentrate feed reference: 4 to 5 months of age, 20 to 30 kg, daily dose of 0.8 to 0.9 kg; 5 to 6 months of age, 30 to 40 kg, daily dose of 1.2 to 1.4 kg; 6 to 7 months of age 40 to 50 kilograms, 1.6 kilograms per day, 3 times a day, regular ration, free water after eating, food, drinking and regular cleaning, regular disinfection. (4) Housing and feeding combined with grazing and fattening To fully utilize the advantages of pastures, a good place for pastures, grazing and house-feeding are used for fast fattening, which can reduce costs. Concentrate formula: 63% of corn, 25% of soybean meal, 10% of bran, 1.5% of bone meal, 0.5% of salt, daily supplement in the morning and evening, and daily feed amount 0.3 to 0.5 kg. During the subtilis period, depending on the physical condition of the sheep, the feed amount of the concentrate can be appropriately increased, and appropriate trace elements and vitamin A and D3 powders can be added. When the temperature of the winter sheephouse is lower than 4°C, measures for keeping warm and keeping warm should be strengthened. (5) Preventing disease The Lamb's adaptability and resistance to disease are weak. Therefore, it is necessary to pay attention to the lamb's mental state, appetite and changes in feces at any time. General lambs should be given 10 mg of oxytetracycline within 36 hours after birth, 2 times a day, even for 3 days, can reduce the incidence of disease. (1) Timely injection of quadruple vaccine (Anthrax, fast-food, goat pox, sheep enterotoxemia). (2) Lamb dysentery. Sulfa 0.5 g, sodium bicarbonate 0.2 g, 1 oral, and even served 3 times, or penicillin 5 to 100,000 units, 2 times daily intramuscular injection. (3) Lamb pneumonia. Intravenous injection of 10% sulfadiazine sodium 5 ~ 10 ml, and add 25% glucose solution 20 ~ 30 ml.
