The result indicated that the meat type flocks of three different farms infection rate of ALV J were 28.12%(9/32)?9.38%(3/32)and 8.33%(10/12),respectively,and all laying chickens infection rate were 0%(0/35,0/10).We chose 6 chickens of ALV J antibody positive and 13 chickens of ALV J antibody negative to do PCR test. The result indicated that 6 chickens of ALV J antibody positive were all PCR positive,and 4 chickens were PCR positive among 13 chickens of ALV J antibody negative. The result indicated that there were ALV J virus not only in ALV J antibody positive chickens but also in some ALV J antibody negative chickens.展开更多
