1 Environmental regulation Design a single flow direction and all-in and all-out turnover piggery. This not only cuts off the way of disease transmission and circulation, but also more importantly meets the requirements of large-scale and standardized production, creates favorable conditions for animal epidemic prevention and production management, and can reduce losses to some extent. Design natural ventilation and mechanical ventilation facilities. This not only ensures the entry of fresh air, but also discharges the exhaled moisture from the pigs, the ammonia gas produced by the excreta, and the particulate dust, which in turn can dilute the pathogens that the pigs emit. This creates a fresh and comfortable environment for the pig house, increasing The disease resistance of pigs. Install warmth facilities. In the cold season, the contradiction between heat preservation and ventilation is more prominent. Warming pigs can effectively alleviate this contradiction. This will not only increase feed remuneration and reduce cold stress, but also reduce the incidence and increase the survival rate of piglets. Consider measures to prevent heatstroke. The summer heatstroke cooling is of great significance. It is possible to create suitable breeding environment conditions by installing fans, vacuum ventilation, drip cooling, and planting trees, so that the sow can live in an environment of 15 to 25°C. At the same time, by adjusting the formula to meet the nutritional needs of high temperature conditions, such as increasing the content of lysine, threonine, vitamin B, C, D and trace elements in the diet, adding 0.1% to 0.2% baking soda in the feed, Or in the drinking water to add 0.1% to 0.2% Vc raw powder, to provide enough cool, healthy drinking water. This can reduce the occurrence of heat stress and improve production performance. Add limit feed bar. The use of limited-feeding bars can not only regulate the feeding amount according to individual conditions, reduce losses, but also reduce the fighting and stress of sows, thereby increasing the fertility rate and birth weight of breeding. 2 Vaccination and epidemic surveillance The vaccination of pig farms should be combined with actual conditions to implement programmed immunization. In the selection of vaccines, we must purchase vaccines from the formal channels, store and use them strictly in accordance with the instructions of the vaccine; we must organize professional veterinarians with strong sense of responsibility and strong professional ability to be immunized; when implementing immunization, they should first Consider viral diseases, such as swine fever, etc.; for diseases that currently have no effective vaccines for prevention, secondary infections should be controlled. For bacterial vaccines, immunity should be minimized. Inoculations should only be considered in epidemic areas. Vaccination should be minimized during childcare. This requires a farm veterinarian to make reasonable arrangements in accordance with the circumstances. Inoculation of pneumonia vaccine during the fattening period may sometimes lead to morbidity, which must be given sufficient attention. On the basis of improving immunization, reasonable arrangements should be made for the detection of epidemics; first-hand information should be provided for the development of practical immunization procedures. 3 Veterinary Drug Usage First of all, it must be clear that all drugs must be purchased by the state from the formal channels, and the use of banned veterinary drugs is strictly prohibited. Secondly, drugs must be targeted and cannot be put in disorder, and rational drug use should be based on susceptibility testing. Third, we must consider the side effects and residue problems of drugs, strictly control incompatibility and ensure the best use of results. We must also strictly enforce the withdrawal period and ensure the safety of live pig products. Fourth, we must consider the cost and calculate the economic cost. Determine the use of drugs, so as to minimize production costs. Different seasons and different stages of growth and development require different feeding and management measures. Adhere to the management methods of self-supporting and self-supporting and all-in and full-out, improve the records of various files, clarify the responsibilities of each post, supervise and urge the implementation of various management measures, and in particular, ensure the prevention and control of epidemics and daily management work to ensure the various farms Work should highlight the center of safe production, so as to reduce the chance of epidemic diseases, timely eliminate pigs with sickness, old age, and declining performance, so that the pig houses can be strictly sterilized and have a certain vacancy time, so that the herds can be purified. In the specific work, we must strictly distinguish the direction of dirt, pigs, feedstuffs, personnel, and roads to prevent cross-contamination. We must adopt a single flow direction of the pigs so that the tools do not collapse, and personnel do not work. The spread of the disease, resolutely put an end to the practice of rehabilitating pigs as a species, actively implemented early weaning, artificial insemination, and other technologies to achieve the purpose of efficient production, safe production, and virtuous cycle development. The application of HACCP in larger farms Management system to improve the level of production management. 4 Nutrition Collocation According to the physiological needs of pigs, fully taking into account the animal's "welfare", such as the use of a reasonable amino acid diet, both reducing waste and ensuring growth needs. The following principles should be followed in the use of feed: (1) Selection of appropriate feeding standards; (2) Feeds should be diversified to achieve a reasonable mix; (3) Selection of fresh ingredients to ensure feed quality; (4) Attention to feed volume , Control roughage content.
