Vaccination of three commercial broiler-breeder flocks at 15 weeks old with viral arthritis/tenosynovitis via the drinking water resulted in serologic conversion of two flocks to agar-gel-precipitin (AGP)-positive, while the third flock was still AGP-negative at 24 weeks, but was AGP-positive at 30 weeks old, presumably as a result of natural exposure. Progeny from the two successfully vaccinated breeder flocks remained free of clinical viral arthritis/tenosynovitis and had average condemnation rates of 0.99%. In contrast, six hatches of progeny from the third breeder flock experienced clinical viral arthritis/tenosynovitis and average condemnation rates of 3.64%.
15周龄时，对三个商品肉种鸡群通过饮水接种病毒性关节炎/腱鞘炎疫苗，结果两个鸡群血清学转化为琼脂凝胶沉淀试验（AGP）阳性，而第三个鸡群在24周龄时仍为AGP阴性，但在30周龄时转为AGP阳性，推测是自然接触所致。两个成功接种疫苗的种鸡群的后代未出现临床病毒性关节炎/腱鞘炎，平均淘汰率为0.99%。相比之下，第三个种鸡群的六批后代出现了临床病毒性关节炎/腱鞘炎，平均淘汰率为3.64%。
