海蓝褐蛋鸡75日龄病变；70日龄左右发病，零星出现，个别伤亡；解剖为非典型新城疫、腺胃炎，用黄芪、利巴、乳环丙、氨苄三天，效果不明显，还是出现、且零星伤亡，第三天解剖法氏囊病变出现，初步诊断新城疫和法氏囊混感；马上打卵黄抗体，接着又用药3天，鸡群没再伤亡，大群也没再出现！[attachment=93114] [attachment=93100] [attachment=93101] [attachment=93102] [attachment=93103] [attachment=93104] [attachment=93105] [attachment=93106] [attachment=93107] [attachment=93108] [attachment=93108] [attachment=93109] [attachment=93110] [attachment=93111] [attachment=93112] [attachment=93113] [attachment=93114] [attachment=93100]
