2. Introduction of live pigs. It is forbidden to introduce breeding pigs or piglets from epidemic areas. Only excellent breeds can really improve the quality of pig products, and then promote the selection of healthy, high-purity and good production performance breeding pigs in the process of production and introduction. Newly introduced breeding pigs must be observed in isolation for a period of time. Observe 15~30 days, and use it after inspection as unhealthy pig. Piglets must be selected from healthy piglets produced by healthy breeding pigs with good production performance. Try to avoid choosing purebred pigs to fatten, because if you choose different breeds to cross, the offspring pigs will usually show greater advantages, so you should cross purposefully. The heterosis of the first generation of hybrid is usually the highest, and at the same time, due to different hybridization methods, various advantages will appear, so it is necessary to combine the actual characteristics of each variety and carry out cross between different varieties in a planned way.
3. Feed carefully. Further promote the promotion of raw feed technology and linear fattening method. After the pigs are bought back, they are fed with clean drinking water or a small amount of green feed. Piglets in good health should be fed diluted feed and chopped green feed after resting for 2 hours. Choose to eat less and eat more meals within a week, and then feed the pigs normally after they adapt to the environment. Feeding feed must be adjusted according to each growth and development period of pigs, and choosing compound feed must meet the nutritional needs of each growth and development period. Scientifically mix concentrate and green feed to control feeding costs. Water plays a key role in temperature regulation, nutrient absorption and metabolism of pigs, so sufficient clean drinking water should be provided. In pig production, feed and feed additives shall meet the relevant national standards, and the use of high residue additives is prohibited. Feeding methods can usually be limited or free, but the daily gain of limited feeding is relatively low, the ketone body fat precipitation is not much, and the lean meat rate is relatively high. The daily growth of free feeding is relatively high, and there are more ketone body fat deposits. In the process of breeding, if you want to gain high daily weight, you can choose to eat freely, and if you prefer to pursue ketone body lean meat rate, you can choose to feed in limited quantities.
4. Daily management. Scientific and effective management methods can greatly promote the improvement of pig breeding benefits. The first is to do a good job in health. Piglets should be disinfected in all directions before entering the pen. The pigsty should be disinfected with quicklime water, and other related appliances should be washed with clear water. Pig farms must have a certain proportion of green area. Pig manure must be disposed of as soon as possible. Ensure the ventilation of the pigsty and create a good environment for the growth of pigs. Second, temperature and light must be effectively controlled. Especially in the case of relatively low temperature in winter, it is more necessary to ensure a reasonable temperature. Third, we should do a good job in training. In raising pigs, it is necessary to train pigs to eat in a fixed position, and at the same time, it is necessary to manage them in groups according to factors such as their physique. The same batch of pigs need to be slaughtered at the same time so that the next batch of piglets can enter the market. During the whole feeding process, it is necessary to ensure that illegal drugs and biological agents are not used to ensure the safety and quality of pork.
5, epidemic prevention and insect repellent. In the process of pig breeding, epidemic prevention is very important, and diseases such as swine fever can only be controlled by preventive means, so there should be no carelessness in the epidemic prevention process. Piglets should be immunized against swine pneumonia, erysipelas and classical swine fever as soon as possible before entering the market, and at the same time, the prevention of streptococcus suis and foot-and-mouth disease should be organized. Farmers must carry out vaccination according to immunization procedures, and organize regular deworming at the same time. When piglets enter the market at the age of 65 days, 438+05 days and 90 days, they should be deworming respectively, and the method of combining body surface deworming with oral deworming should be adopted. 65,438+0.0% trichlorfon solution can be selected for body surface deworming and albendazole (5 ~ 40 mg/kg) can be selected for oral deworming.
6. It's time for slaughter. After reaching a certain growth stage, it is necessary to arrange pig slaughter in time to ensure maximum economic benefits. Generally speaking, it is best to slaughter pigs when their weight reaches 90 ~ 120 kg.
