(1) Establish pollution-free industrial and mining enterprises, enterprises, site-to-site infectious diseases, and air, soil, water, and Other environmental indices that all meet the standard. The farm (household) should have a quiet environment, complete disinfection equipment, strict disinfection system, tight control of stocking, proper temperature and humidity in the sheep house, good ventilation, and creating a good ecological environment for the pollution-free breeding of Boer goats. (2) There is a common problem in the production and feeding of “green†feeds, which makes the sources of feeds widely and miscellaneously, and the contamination and residue of raw materials are difficult to control. Therefore, it is required that the feed must have a fixed range of pastures and raw material, and the production area must be a green crop production base. The varieties of high-quality forage grass suitable for cultivation include broadleaf ryegrass, Rumex k-1, alfalfa and Mexican corn. Throughout the process of breeding Boer goats, use “green†feed that meets requirements without contamination, residue, and pollution. (3) Purchasing pure boer goats When purchasing Boer goats, be sure to go to regular manufacturers to purchase them. When purchasing seedlings, you must also obtain their pedigrees. Can not think of the head brown, ear hanging down is the Boer goat, and ignore the wave of goats straight back, strong limbs, muscular main signs. The ram's horns are curved and curved outwards. The slats are of good quality and have strong resistance to diseases and parasites. (D) The selection of local elite ewes in the production of mutton sheep, the selection of Boer goats as a cross-father, the local ewes should be the necessary choices. Due to the neglect of goat breeding, breeding, and unplanned promiscuous and inbreeding mating for a long time, many local breeds are impure, small, and severely degraded. Therefore, in order to obtain a good hybridization effect, it is necessary to carry out the hybrid rejuvenation of the local goat, or directly use the goat of good quality as the female parent. For example, Liaoning Cashmere Goat, Laoshan Dairy Goat, Nanjiang Yellow Goat, Yangtze River Delta White Goat, Huanghuai Goat, and Goat goat. Should choose the body with large body size, high lambing rate, and more milk production as the female parent. (V) Making full use of the advantage of hybridization The hybrid goats with many excellent genes and the local ewes have good hybridization advantages. For example, the birth weight, age of 2 months, 6 months of age, and 6-month daily weight gain of the Bo hybrid generation sheep are respectively increased by 80%, 75%, 70% and 60% compared with the local sheep; the lambing rate is 180% - 220%, the slaughter rate reached more than 50%, and the eastern weight increased by nearly 40%. (6) The raising of traditional feeding and management techniques has far outpaced the technical requirements for the modern breeding of Boer goats. In feeding and management, we should actively implement the "six changes" and "six promotion" technical measures. “Six changes†are used for drug abuse in technological reforms; when the level is changed, no disease is prevented and the disease is rectified to establish a perfect pest prevention and deworming procedure; single grass is used for feeding diversified forage and intensive supplementation; ground leveling is changed. Sheep are raised on high beds and bamboo beds; they are raised in plastic sheds in the winter and the rams are not fattened for fattening. “Six promotion†technology promotes ecological principles to prevent disease, improve product quality, achieve pollution-free, residue-free, pollution-free green food; promote sheep artificial insemination technology, improve the utilization rate of Boer goats; promote ewes for two years Fetus breeding techniques to improve the rate of herding and raising lambs; promote lamb slaughter techniques for the year of the year and increase the slaughter rate; promote proper management of raising sheep and raise the scale of breeding benefits; promote grazing, housing and feeding, and improve scientific rearing . The sheep pen should be simple but not leaky. Ensure that the lamb eats full colostrum, carefully manage it after weaning, supplement salt and bone meal. (7) Perfecting the epidemic prevention system for pest prevention We must formulate a relatively perfect epidemic prevention program in accordance with the local actual conditions, plan epidemic prevention programmatically, and use interconnected vaccines for vaccines. Individual infectious diseases that are popular in the area should also be epidemic prevention. Regular cleaning inside and outside the sheep pen, regular disinfection. Disinfect it with vegetation grey water or 10%-20% lime milk solution or 5%-10% bleaching solution; use Chinese herbal medicine to prevent and treat disease when it needs treatment: feed the sheep with fresh poplar leaves in summer and feed it both The occurrence of epidemic diarrhea can also be done with dried poplar flowers or fresh leaves, decocted with fragrant juice and can be used to treat diarrhea; the treatment of boer goat goose sores with soybeans, taking appropriate amount of soybeans, roasting black in a wok, grinding into powder, Into the sesame oil into a paste, and then lightly applied to the sheep affected area once a day, usually 3-5 times to cure.
