At present, it has entered the autumn. The management of pig raising in autumn is mainly for preparing for winter production, reducing the incidence rate of pigs, and improving the economic benefits of farms. Therefore, we must make good use of pig raising equipment. Cool climate and suitable humidity, suitable for pig growth and development. Therefore, pig farmers should seize the critical period of autumn, improve the technical level of pig breeding, and achieve the purpose of increasing production and efficiency.
1、 Pay attention to the management of pig herd in autumn
In autumn, the fattening pigs should be fed in two stages according to their body weight (25-60kg in the early stage and 60-100kg in the later stage). According to the nutritional needs of the pigs, the local feed resources should be selected and the concentrated premix should be used to match the full price ration for the pigs. In the aspect of pig management: first, we should do a good job of reasonable grouping. Generally, it is better to raise 10-20 pigs in each circle to ensure that each pig has a suitable field area (usually 0.4-0.8m2/head in the early stage of fattening and 0.8-1.2m2/head in the later stage), and keep the weight of pigs in the same circle uniform. The second is to do a good job in the "three-point positioning" of pigs, so that pigs from the beginning to develop a fixed place defecation, feeding and sleeping habits.
2、 Develop a comprehensive plan to deal with diseases in autumn and winter
The prevention of respiratory diseases mainly considers improving the environment and necessary health care prevention. How to make the pig group from the free big window ventilation to the weak ventilation of the closed house, we need to pay attention to the climate change every moment, adjust the air volume through the window switch, and prepare the relevant facilities in advance. The prevention of FMD is mainly caused by the lack of antibodies in the pig population, so it is necessary to scientifically increase the dose of vaccine injection, increase the number of injections, and use high-efficiency vaccine after autumn.
Infectious gastroenteritis and epidemic diarrhea are common infectious diseases in autumn and winter. Before mating, the reserve sows should be injected with inactivated vaccine of swine epidemic diarrhea to produce sufficient active immunity; the pregnant sows should be inoculated with twice attenuated vaccine of transmissible gastroenteritis and rotavirus by intramuscular injection or intranasal injection 5-6 weeks and 1 week before delivery, so that the suckling piglets can obtain antibodies by colostrum, have better passive immune effect and reduce morbidity and mortality.
For the prevention and control of viral diseases, another important thing is the resistance of the body itself. Adding 0.5% odelman a to the feed can enhance the non-specific resistance of the animal itself, reduce respiratory diseases and promote growth.
3、 Pay attention to feeding management in autumn pig raising
When raising pigs in autumn, in addition to strengthening conventional feed management, we should also do a good job in pig feed storage and fattening.
1. Feeding method
In the feeding method, the raw meal was wet fed and drinking alone, and the powder mixture was mixed with water before feeding according to the ratio of 1:1-1:1.5. Establish the life system of regular and quantitative feeding. In order to promote digestion and improve feed utilization rate and growth speed, fattening pigs can be fed regularly three times a day. In addition, the appetite of pigs is generally high in the evening, followed by the morning, and weak at noon. Therefore, the feeding amount of each time in a day can be roughly divided into 35% in the morning, 25% in the noon and 40% in the evening.
2. Prevention of mycotoxins
There is a lot of rain in autumn, and the stored raw materials are prone to mildew and deterioration. We must check the quality of corn and fish meal frequently. If problems are found, they should be dealt with as soon as possible. If mildewed is not serious, they can only be fed after treatment. If mildewed is serious, they must not be fed to prevent poisoning. In autumn, the new corn will be listed on the market at a low price. The farmers must purchase and store a large amount of corn. In the storage process, they must pay attention to the moisture and impurity content of corn, and do not blindly purchase and store corn, so as to avoid great losses.
3. insect repellent
Autumn is the key period for deworming. The harm of parasites is invisible and persistent, which causes serious losses to farmers. In this period, the purpose of deworming is to remove the parasites inside and outside the pig body, make effective preparation for the winter feeding of the pig and reduce the economic loss. The whole group uses the compound deworming drug mixture to deworming for one week continuously, and can use it again every two to three weeks, so as to remove the parasites inside and outside the pig body more thoroughly.
