用禽白血病病毒（ALV）阴性和ALV J亚群（ALV-J）阳性种鸡孵化肉鸡后代。通过p27抗原捕获酶联免疫吸附试验和对孵化时获得的血清或血浆样本进行ALV-J特异性逆转录聚合酶链反应来鉴定后代感染ALV-J。alv - j阴性肉鸡和alv - j阳性肉鸡的孵化重无显著差异。1周龄时alv - j阳性肉鸡体重为alv - j阴性肉鸡体重的64.4%。8周龄时，先天性ALV-J感染肉鸡体重仍仅为alv阴性肉鸡体重的63.8%。两组肉鸡均未检出其他并发致病菌。这些发现表明，在没有其他病原体的情况下，先天性ALV-J感染与肉鸡体重显著下降有关。
Broiler progeny were hatched from avian leukosis virus (ALV)-negative and ALV subgroup J (ALV-J)-positive breeders. ALV-J infection in progeny was identified by p27 antigen capture enzyme-linked immunosorbent assay and reverse transcripcase-polymerase chain reaction specific for ALV-J performed on serum or plasma samples obtained at hatch. Hatch weights did not differ between ALV-negative broilers and ALV-J-positive broilers. Body weights of ALV-J-positive broilers were 64.4% of those of ALV-negative broilers ac 1 wk of age. At 8 wk of age, weights of broilers with congenital ALV-J infection were still only 63.8% of chose of ALV-negative broilers. No other concurrent pathogen was detected in either group of broilers. These findings indicate that congenital ALV-J infection is associated with significant weight suppression in broilers in the absence of other pathogens.
