Avian leukosis purification field area and purification method thereof

Abstract

The invention relates to an avian leukosis purification field area. The avian leukosis purification field area comprises a life management area, a production area and a dirt treatment area which are isolated by adopting enclosure walls, wherein sewage generated by the purification field area is discharged to a sewage treatment place through a sewage pipe; a vehicle disinfection tank and a personnel disinfection channel are arranged at an entrance of the life management area; a personnel disinfection channel and a shower room are arranged at an entrance of the production area. The invention further relates to an avian leukosis purification method. The avian leukosis purification method comprises requirements of infrastructure in the purification field area, and the requirements of biological safety, production management and purification detection are formulated. The avian leukosis purification field area is compact in layout and reasonable in design, and purification matching measuresare specified in detail, so that the avian leukosis purification field area has practical guiding significance and good operability; according to a purification detection scheme involved in the purification method, a production stage can be flexibly selected for detection according to actual conditions in the field, and detection time points are all avian leukosis detoxification peak periods of breeding hens, so that the infection positive rate of groups is rapidly reduced, and the production performance of purification groups is effectively improved.

Description

technical field [0001] The invention relates to the technical field of avian leukemia purification, in particular to an avian leukemia purification field and a method for purifying avian leukemia. Background technique [0002] Avian leukemia (Avian leukemia, AL) is a poultry neoplastic disease caused by the avian leukemia virus (ALV) of the Retroviridae family. It is one of the three major diseases that commonly exist in chickens and induce tumors. my country's poultry industry is very harmful, affecting almost all commercial chicken flocks. Relevant studies have shown that chickens infected with ALV not only cause tumors and lead to direct morbidity and death, but also seriously affect the production performance of chickens, delay sexual maturity, shorten egg production peak maintenance time, reduce egg production rate, and reduce fertilization rate, especially after vertical infection. Seriously affect the hatchability of eggs and the quality of chicks. At present, there ...

AI Technical Summary

Problems solved by technology

[0006] At present, the avian leukemia purification technology adopted abroad is mainly based on the purification methods of large-scale enterprises in Europe and the United States, but the purification mode is time-consuming and laborious. The original breed chicken farm is restricted by many factors such as economic conditions, technical level and breeding mode, and cannot be copied. In recent years, domestic To carry out beneficial exploration on the purification technology of avian leukosis, and establish a purification scheme suitable for local breeding chickens and parental chickens, but the purification schemes are quite different, the detection time point is random, and the purification effect is uneven. There are few studies on the situation of avian leukemia in pheasants, the situation of virus infection is still unclear, and the purification scheme is still blank; in addition, the existing purification technology often does not describe the relevant facilities used for purification in a comprehensive and detailed manner, so it lacks practical application value
