How can retail pig farmers prevent diseases correctly and effectively?

At present, great changes have taken place in the mode of raising pigs in rural areas. the production speed of fattening pigs has been accelerated, the fattening period has been shortened a lot, and the annual fattening rate of pigs has been greatly improved. from the overall decentralized and extensive management to a variety of degrees of intensive scale management, but due to the substantial increase in feeding costs and the complexity of the epidemic, the expected economic benefits have not been achieved. In order to maximize the growth performance of pigs, reduce feeding costs and improve comprehensive benefits, how can retail pig farmers prevent diseases correctly and effectively? These problems cannot be ignored.

I. reasonable prevention

The breeding rate of vaccinated pigs depends to a large extent on the use of vaccines to prevent diseases. In view of the common infectious diseases in pigs, such as classical swine fever, porcine lung disease, porcine erysipelas, piglet paratyphoid and so on, it is necessary to formulate immunization procedures suitable for the epidemic trend of local epidemics to achieve overall prevention. The vaccine should select qualified and efficient products and use them correctly according to the product instructions.

Prevention can be carried out with reference to the following procedures: 20-day-old swine fever vaccine; 55-day-old swine fever, swine erysipelas, swine lung disease triple vaccine; 70-day-old piglet paratyphoid vaccine (if necessary, 55-day-old vaccination). As the epidemic situation and trend of infectious diseases are different in different places, it is difficult to find a fixed immunization procedure suitable for each field. Therefore, we should change the vaccination time, increase or decrease the number of vaccination and change the type of vaccine as appropriate.

2. Reasonable deworming

Due to the limitations of sanitary conditions and management measures, compared with intensive pig farms, the chance of parasite infection in rural pig farms may increase, and the harm is more serious, and because of the high incidence of parasites, but the mortality rate is relatively low, and the symptoms are not obvious. It's easy to ignore. Therefore, the overall loss caused by parasites is serious and recessive. Pigs only eat food without gaining weight or less weight (and may even eventually develop into stiff pigs), and the disease resistance and stress resistance of pigs decline, so it is necessary to establish a deworming program suitable for their own herds. In this regard, it is particularly important for some pigsty groups with poor hygiene.

Deworming drugs with broad spectrum, high efficiency and low toxicity can be used: avermectin (Alijia) or ivermectin (Ivermectin, killed) to drive nematodes in vivo and kill external parasites, albendazole (albendazole, anti-vermin) or praziquantel to drive tapeworms and trematodes, they can basically cover the main parasitic infections in pigs, but we should also pay attention to the recent upward trend of piglet coccidiosis and toxoplasmosis. It can be dewormed three times at 45 days old, 90 days old and 135 days old. Daily health management:

1. Pigs must be provided with adequate clean drinking water. Insufficient or limited drinking water may affect food intake and feed return rate; unsanitary drinking water is easy to induce or spread diseases, which is a very important way of infection of pathogens. Therefore, the pigsty should always ensure that there is a clean water source for pigs to drink freely, and the material trough should be separated from the sink.

2. Wash the lees and sinks regularly to remove pollutants such as rotten feed residue and feces and urine in the trough. it is best to expose them in the sun for a period of time or disinfect them.

3. Regular cleaning and disinfection is an effective way to reduce infectious diseases in pigs. Disinfection products that are cheap and easily available, such as plant ash, quicklime and bleach, should be disinfected regularly according to their own practice. Before disinfection, the feces and urine should be cleaned first, the pigsty should be washed, and the daily feces and urine should be treated regularly.
