The characteristics of ramie in Chengdu and its breeding points

Characteristics of a Chengdu Mayang Chengdu Mayang is a meat and skin breed that has fast growth, early maturation, high fertility, strong adaptability, resistance to heat and moisture, extensive feeding, and stable genetic properties. It is especially tender and delicious. , No odor, large area of ​​the board, texture is the most significant feature. In 2001, the Shuangliu County Animal Husbandry and Food Bureau, with the support of the provincial bureau, collected samples of Chengdu mutton and sent them to the Sichuan Academy of Animal Sciences (measured according to national standard GB5009-85). Fresh meat: moisture accounted for 75.45% and fat accounted for 1.52%. Protein accounted for 22.0% and ash accounted for 1.03%. Muscle fiber fineness 58.03um. The amino acid content of fresh meat was (liquid chromatographic method): aspartic acid 1.83%, threonine 0.94%, serine 0.74%, glutamic acid 3.41%, glycine 0.98%, alanine 1.20%, cystamine Acid 0.36%, Proline 0.99%, Methionine 0.50%, Isoleucine 0.94%, Leucine 2.00%, Tyrosine 0.74%, Phenylalanine 0.89%, Lysine 1.59%, Histidine 0.70 %, Arginine 1.39%, Proline 0.83%. The area of ​​sheep's skin is more than 5,000 square centimeters and the area of ​​adult sheep skin is more than 6,500 square centimeters. The cortex is compact, uniform in thickness and elasticity, with high tensile strength and no blemish. After processing into leather, the leather surface is smooth, grainy and delicate, soft and tough, and resistant to wear. Its board quality is the highest in Sichuan goat breeds. It is the best and best raw material for high-grade leather (shoe upper leather) and high-grade oil filter leather. Two Chengdu Ma sheep breeding points Chengdu Ma sheep and other goats, although it has a strong adaptability, but it also requires careful feeding and management. I. Feeding and management points 1. The sheep house should be built on a high-lying, dry land with adequate water resources and relatively convenient transportation. It should be far away from high-voltage wires, roads, railways, and urban areas, factories, schools, airports and other densely populated areas. Ventilation is light, cool in winter and cool in summer, easy to clean and sanitary. 2, forage should be cleaned after harvesting, does not contain sediment, dirt, plastics, nails and other impurities, cool sun wilting, and squat short to about 5cm. Feeding should be based on grass, supplemented by fine material, to ensure diversification of forage, to do with dry, with coarse and coarse, first coarse after finishing, less feeding Tim Tim, regular quantitative. 3, drinking water should be clean, free of sediment, water and other impurities. To provide adequate supply, free drinking, winter warm hot water, do not feed frozen water; summer drinking water should be close to the natural temperature, not too different from the body temperature of the sheep. 4, supplement the amount of concentrate, salt and trace elements. Pay attention to the quality of concentrates, and not make any changes. The amount of supplements for concentrates, salt, and trace elements should be determined according to the sheep's different growth stages and different uses (seeds, fattening sheep, etc.). 5, depending on the use of the sheep only to properly arrange the amount of exercise, adequate exercise for breeding sheep, fatten sheep to limit exercise. During the exercise, the sheep should only be prevented from being exposed to the sun and rain. 6, to keep the house clean, air dry, fresh ammonia-free. 7, equipped with mosquito repellent fly facilities, such as burning repellent tablets, sandalwood, placed fly paper and so on. Second, the epidemic prevention and control points to adhere to prevention, comprehensive prevention and control principles. 1. Regular cleaning and disinfection: Clean the pens every morning and evening and disinfect the pens regularly. Ground, environment, and utensils can be disinfected with 2% alkaline water or 10-20% lime water; sheep beds, food troughs, and sheds are sterilized with David and Poison. Houses and utensils are disinfected once a week, and the environment is disinfected once every half month. Disinfectants should be used alternately to prevent bacteria and viruses from developing resistance. 2. Regular deworming: Deworming must be performed regularly. The fattened sheep were deprived for the first time on the premise of good health and normal feeding. Afterwards, the worms were driven every three months, and the insects were stopped one month before the slaughter. Breeding sheep can be determined according to specific conditions, and ewes are generally dewormed during non-pregnant periods. Deworming medicines are commonly used as insecticides, such as ivermectin and abamectin. The dosage is tablet: 2 mg/tablet, 10 kg body weight takes one tablet; Injection: subcutaneous injection, 0.2 mg/kg body weight. 3, to do a good job of vaccination of the disease: (1) inoculated sheep triple vaccine, pay attention to the sheep epidemic, sheep, sheep intestinal toxemia and other diseases prevention. (2) Inoculation of sheep contagious pleuropneumonia vaccine to prevent the occurrence of contagious pleuropneumonia in sheep. (3) Inoculation of sheep infectious aphthous vaccine to prevent the occurrence of contagious aphthae in sheep. (4) Inoculation of sheep infectious conjunctivitis vaccine to prevent the occurrence of contagious eye conjunctivitis in sheep. (5) Inoculate goat vaccinia to prevent the occurrence of goat pox. Chengdu Mayang is suitable for growing in climate conditions with mild climate, abundant rainfall, four distinct seasons and long frost-free periods. It can also adapt to the environment and climate conditions of high temperature, high humidity, and high-cold areas. As long as the comprehensive supporting technology of high bed and housing is combined, the performance is also ideal. Has been promoted to Gansu, Xinjiang, Hunan, Hubei, Guangdong, Guangxi, Henan, Hebei, Shaanxi, Jiangxi, Guizhou, Fujian, Yunnan and other provinces, have shown good adaptability. Chengdu Mayang was involved in the cultivation of Nanjiang Yellow Sheep with good meat quality, excellent quality of plate skin, and good and stable genetic performance. It successfully cultivated the first generation of new-generation meat goat breeds in China. As the main male parent of Nanjiang Yellow Goat, a high quality meat goat breed, it is also an important source base for meat goat production. It plays an important role in improving local goat production performance, improving the quality of goat meat, and increasing farmers' income.
