1. Reducing Feeding Costs Sheep are herbivores and have a slower growth and development rate than food-eating pigs and pigs, and their production efficiency is low. Therefore, the reduction in feed costs is the key to the success of large-scale sheep farm operations. In areas where the price of high-quality peanut meal, sweet potato meal and soybean meal is above 0.15 yuan/kg, we must adopt grass-raising sheep or silage technology to ensure that the cost of forage grass is reduced. For example, planting high-quality forage grass can better solve the problem of high quality straw shortage in sheep breeding areas and the high price of high-quality straw, limiting the development of large-scale sheep breeding. In addition, micro-storage, ammoniation, alkalinization and other advanced straw processing technology, is also a key technology to improve the utilization of low-quality straw, reduce feed costs. For example, the use of fermented straw powder and bran, followed by some corn quail feeding, eliminates the need for additional bean cake feed, which is more effective in reducing feed costs. 2. The selection of elite male parents should choose varieties with large individuals, fast growing speed, wide recipes, good meat performance, good meat quality, high slaughter rate and strong adaptability. Saanen dairy goats are often used as the first male parent and the Boer goat as the second male parent in production. 3, to determine the hybridization model goat hybrid binary hybridization, three-way hybridization and progressive hybridization three ways. If large-scale farms or large breeding families feed local goats, Saanen goats or Boer rams can be introduced for binary crossbreeding. Hybrid male rams are all fattened, and hybrid female ewes can be fattened and used as seeds for reuse. Goat hybrids. Among them, the cross between the Sabine binary ewes and the Bol rams is called a three-way cross, and all the crossbreds are fattened; the cross between the bougainvillea binary ewes and the polo rams is called the advanced binary crossbreeding, and the Posabbon The ternary crossbred ewes were then crossed with the Bol rams to become triads. From the perspective of hybridization, three-way hybrids are superior to binary ones, and triad hybrids are superior to three-way hybrids. 4. Adjusting the lambing season and increasing the survival rate of lambs. Some countries, such as the United States, attach great importance to the breeding season and mass production in lamb production. The experience is that lambs are intensively raised in March and listed on the market from July to November. China's Hebei, Guizhou and other provinces have also done some research in this area and summed up some useful experiences. According to China's specific conditions, the same period of estrus reproduction technology can be used to adjust the breeding season to September to October, the second year of March to March concentration of lambs, can effectively reduce the mortality of lambs. 5, timely immunization insecticide inside and outside the sheep's house should be regularly cleaned, and bleaching powder, poisoning and other regular disinfection. In the spring and autumn seasons, the animals were repelled with broad-spectrum anthelmintic drugs such as disometamin, levodozole, and trichlorfon, and three pairs of seedlings or five pairs of seedlings and goat pox were selected according to the epidemic situation of the local herd. , Vaccine against inactivated foot-and-mouth disease, and infectious pleuropneumoniae vaccine are regularly or irregularly vaccinated. 6. Grasping the moderate scale The scale of meat goat farming depends on many factors such as the investment ability, market price, forage area, feeding and management conditions, and the proportion of male and female farmers. Practice has shown that the minimum size of rearing hens should not be less than 20, and the appropriate size should be 40-50. It is advisable to control the breeding scale of specialized large households specializing in lamb fattening to 100-150 eggs. 7. Reasonable group rearing Due to the different production purposes of breeding sheep, gestating ewes and lambs, there are different requirements for forage feed quality and feeding and management conditions. Polyculture tends to cause lack of nutrition for the lambs, prolonging the period of fattening and further increasing the cost of rearing. Kinds of rams mess with each other, affect their utilization, and even lead to the overall degradation of the flock. Therefore, farmers should rationally group herds according to their purpose, requirements and age structure. 8. The construction of high-bed sheep collar slatted floor sheepfold has the advantages of drying, ventilation, and easy removal of feces, which can greatly reduce the occurrence of sheep diseases. The height of the slatted floor from the ground is 30 to 50 cm. Wooden and bamboo pieces can be used for the plates. The distance between them is about 3 cm. In winter, a wooden sheep bed should be placed on the slatted floor for the sheep to lie down. At the same time, it is necessary to teach goats to excrete feces at regular intervals to keep the sheep bed clean and dry. 9. Lamb fattening goals for fattening lambs to increase daily gain and feed utilization. Feed minerals and concentrates on the premise of ensuring sufficient green feed or hay. Farmers can purchase goat mining quality bricks and hang them in a circle for sheep to feed freely. Concentrates can be prepared using corn, soybean cake and other raw materials. Its formula is: corn 55%, wheat bran 25%, rice bran 4%, rapeseed cake 8% and bean cake 8%. 10. Appropriate body weight of slaughtered meat Suitable for body slaughter of sheep is based on the comprehensive evaluation of daily production weight, feed utilization rate, slaughter rate, and other performance indicators and market demand. The slaughter weight is too low, the growth potential of mountain sheep has not been fully exerted, and the amount of meat produced is also low; the weight of the slaughter is too high. Although the amount of meat produced increases, the feed utilization rate decreases. The peak period of hybrid sheep growth was later than that of local sheep, and its appropriate slaughter weight should be larger than that of local sheep.
