After weaning, nursery pigs lose the protection of maternal antibodies, coupled with their own weak immune and anti-disease mechanisms, low levels of antibodies in the body, and are very susceptible to pathogens in the external environment. The spectrum of pathogens and the number of pathogens carried in each batch of pigs are different, and there will be a large number of pathogens in their secretions and excrement. Therefore, before piglets enter the pig fatten crate, all of the previous batch must be removed. Pigs, then can enter pigs. This principle must also be followed before fattening pigs enter the house-that is, all in and all out.
2.Pigs can only be imported after nursery and pig fatten crate cleaning
The nursery house and pig fatten crate must be cleaned before entering the pigs. The aisles, manure ditch, and the floor of the manure leakage must be removed for cleaning on both sides to ensure that there are no future troubles and difficult-to-clean dirt. Soak them in warm water with detergent before proceeding. Rinse, disinfect after drying, and dry for later use. In this way, a comfortable and safe environment can be provided for the pigs that will be transferred.
