The invention discloses a method for purifying
avian leukosis of Rizhao partridge chickens, which relates to the technical field of poultry breeding and comprises the following steps of uniformly arranging specific light sources in a chicken house, and setting specific breeding density, regularly feeding vitamins, selecting a target purified
breeding chicken flock, eliminating positive chickens to construct an F0 generation breeding
flock,
hatching eggs to generate an F1 generation breeding
flock, respectively carrying out
antigen detection at different times to remove positive chickens, carrying out height, body length and
body height detection and screening, constructing an F1 generation breeding purified flock, and
hatching eggs to generate an F2 generation breeding flock, and enabling the rest to be done in the same manner until the F4-F6 generation breeding purification
population, and acquiring the purification
population when the 300-day-old
antigen detection reaches zero
detection rate. According to the method provided by the invention,
population purification of the
avian leukosis can be completed, the capability of the population obtained through purification for resisting the
infection risk of the foreign
avian leukosis is remarkably improved, chickens are not easily infected with the avian leukosis, the morbidity after infection is low, and the death rate after
attack is low.
