摘要
为了获得仔猪PRRS母源抗体的试验数据,制定科学的PRRS免疫程序,作者对新疆吐鲁番市和奇台县专业养猪场的商品代仔猪,用间接ELISA方法对血清样品进行猪繁殖与呼吸综合征母源抗体的跟踪监测。结果显示,吐鲁番3个试验组和奇台县5个试验组的商品代仔猪的猪繁殖与呼吸综合征母源抗体持续期随着时间的推移呈递减趋势。在仔猪28-35日龄时,8个试验组的商品代仔猪PRRS母源抗体水平逐渐下降到临界值(S/P值≥0.4),并确定PRRS首免日龄为28日龄。
A The maternal antibodies against porcine reproductive and respiratory syndrome(PRRS)in commercial piglets in professional pig farms of Turpan and Qitai County were surveyed by direct ELISA. The results indicated that the level of maternal antibodies in piglets of 3 test groups of Turpan and 4 test groups of Qitai County was gradually reduced and went out with the time after immunization. The level of maternal antibodies against PRRS in 28~35-day-old commercial piglets of the 8 test groups was gradually decreased to a critical value(S/P ≥ 0.4),and hence the first immunization was determined at 28-day-old age.
