Embodiment

[0031] A purification method for avian leukemia, specifically the following steps:

[0032] (1) Establishment of biosafety system

[0033] In the initial stage of purification, set up infrastructure according to the needs of purification, and formulate a complete set of environmental sanitation and disinfection and biological safety and epidemic prevention systems or measures;

[0034] (2) Refined management in the production process

[0035] A hatching link: set up an independent hatching hall, independent hatching machine and hatching machine, so as to achieve single-line hatching and single-family hatching;

[0036] B production link: feeding in small cages during the brooding and rearing stage, single-cage feeding during the egg-laying stage; after the detection and elimination in the breeding stage, the negative chickens should be moved into the chicken house that has been cleaned and disinfected as soon as possible, and environmental sanitation should be strengthened to...

Abstract

The invention relates to a purification method of avian leukosis. The method comprises the following steps that 1, a biological safe system is built; 2, delicacy management in the production process is conducted; 3, the purification procedure of the avian leukosis is conducted. Through long-time experiment, purification of the avian leukosis is conducted by using the purification method, the positive rate of the avian leukosis of all-strain avians is smaller than 1%, the Tiejiaoma strain reaches the negative, and the effect is remarkable; compared with the three purification steps of reduction, control and eradication of the avian leukosis in the prior art, eradication of the avian leukosis is regarded as a target of the purification method of the avian leukosis at the very start, all procedures and measures are conducted according to strictest standards, double results are achieved with half effort, and the purification method is worthy of application and popularization.

Description

technical field [0001] The invention belongs to the technical field of biology, and in particular relates to a method for purifying avian leukemia. Background technique [0002] Avian leukosis (AL) is a general term for a variety of tumor diseases in poultry caused by viruses in the avian leukosis virus (ALV) and avian sarcoma virus (ASV) groups. Only chickens can infect avian leukosis under natural conditions, and the resistance of chickens of different breeds or strains to virus infection and tumor occurrence varies greatly. The susceptibility of hens is higher than that of roosters, and it mostly occurs in chickens over 18 weeks old, and the case fatality rate is 5%-6%. ALV can be transmitted both vertically and horizontally through breeding eggs, so the disease has always been an important disease in the production of breeders and laying hens. [0003] In the prior art, the purification of avian leukemia can be simply divided into three stages, that is, reduction, cont...
