Method for identifying DHAV-3 character resistance of Beijing ducks and application of method

The invention discloses a method for identifying DHAV-3 character resistance of Beijing ducks and application of the method. One technical scheme protected by the invention is application of a substance for detecting the concentration of high-density lipoprotein and/or low-density lipoprotein in duck blood in identification or auxiliary identification of anti-duck hepatitis A virus gene type 3 infection traits of ducks. According to the embodiment of the invention, the DHAV-3 infection resistance of the ducks of which the contents of high-density lipoprotein and low-density lipoprotein account for the first 5% of all to-be-detected ducks is higher than that of other to-be-detected ducks; on the basis, whether the to-be-detected duck resists the duck hepatitis A virus gene type 3 or not can be identified, the DHAV-3 resistance character of the Beijing duck can be selected, the cost is saved for preventing and controlling propagation of duck virus hepatitis in the duck breeding industry, the genetic progress is
