Outsourcing piglets to five off

With the continuous development of large-scale pig raising, some pig farmers (fields) that do not have the capacity for self-cultivation and self-cultivation have to purchase large quantities of piglets from other places all year round. However, if they are careless, there may be epidemics of outbreaks of piglets. Suffer unnecessary economic losses. The author believes that outsourcing piglets should pay attention to the following "five levels."

Before buying the piglets, go to the local animal husbandry and veterinary department to find out whether there is an epidemic in the place of origin of the piglets to be purchased. If there is an outbreak or if an outbreak is selected, the veterinary technicians can contact the veterinary technicians. To go to a qualified pig breeding farm. According to the characteristics of the purchase of varieties, choose physical appearance, growth and development, good health individuals.

After the quarantine has been completed, the local animal quarantine personnel should be quarantined and a transportation quarantine certificate and vehicle and ship sanitation certificate (certificate of exit from the county) should be issued. At the same time, the transport vehicles and transport equipment should be disinfected.

For transportation, the transport vehicles and cages should be selected according to the size and quantity of the piglets, and vehicles equipped with wind and rain should be provided. If the cage used for the pig is welded with steel, it is necessary to prevent the joint with a hook or sharp from being exposed in the cage and out of the cage to avoid scratching or stabbing the pig. The second is to clean the transport vehicles before loading the pigs and disinfect them with peracetic acid or poison. Vehicles that regularly transport livestock are more often sterilized to completely kill pathogens. The third is not to feed the piglets too much feed before loading, but it is advisable to give enough drinking water. Fourth, the piglets should not be exposed to rain and sun exposure during transportation, and they must be kept warm and cold in autumn and winter. Fifth, transport vehicles should maintain a uniform speed during driving and avoid emergency braking. If long-distance transportation is necessary, piglets should be given water in due course.

Segregation farms should be set up in isolated farms. Isolation farms should be located more than 300 meters away from the farm production area. Piglets purchased should be kept in the isolation farm for 15-30 days to prevent the spread of the disease. The other pigs within, if reserved for use, should be kept for at least 3 months. After the period of observation is over, it is found that it still has no disease before it can enter the production area. Segregation and utensils must be strictly disinfected prior to the outsourcing of the piglet. Disinfectant can be treated with 20% fresh lime milk, 5% bleach solution or a good quality disinfectant. Disinfection should be thoroughly cleaned, and then multiple scrub or spill with a disinfectant solution.

The first step in management is to refrain from rushing to feed concentrated feed after the out-going piglets are shipped to their destinations. They should be allowed to drink clean water with a small amount of salt first, then feed a small amount of feed after 2-3 hours, and gradually increase the amount of feed afterwards. . The second is that piglets purchased should be grouped in groups and kept in separate rows. Thirdly, piglets, pig erysipelas, and foot-and-mouth disease vaccines were vaccinated within 1 week after the piglets were bought back. After 20 days, foot-and-mouth disease vaccines were exempted. In addition, immunizations against swine streptococcosis, blue ear disease, edema, etc. should be performed based on the local swine epidemiological characteristics. Fourthly, one week after inoculation of piglets with various types of vaccines (that is, no problems were found on the piglets and they were raised for about 20 days). If the disease is still not found, the piglets should be dewormed and stomachically. The specific approach is: 1 Let the piglets be hungry One day, use levamisole tablets to repel insects, use 8 mg per kilogram of body weight, mix the powder and mix in the feed, let the pigs eat once, and ensure that each pig can eat, or intramuscular injection of levamisole injection. 2 On the third morning, use rhubarb soda tablets to stomach, grind the powder at a dose of two tablets per 10 kilograms body weight and mix in the feed and feed it.

After 15-30 days of isolation observation and strict quarantine inspection, the piglets could be transferred to the production area without any problems. Before entering the production area, strict disinfection of the piglets should still be performed.
