Examination of nearly 2000 sera indicated that approximately 90 per cent of cattle had acquired Dictyocaulus viviparus infections during the previous grazing season. No differences were found between provinces. Large differences were seen between herds. Antibody titres of milk cows on zerograzing farms were significantly lower than on comparable farms where animals were pastured. The need for further epidemiological work is stressed. In such work serology can be helpful.
对近2000份血清的检测表明，大约90%的牛在之前的放牧季节感染了胎生网尾线虫。各省之间未发现差异。不同牛群之间差异很大。零放牧农场的奶牛抗体滴度明显低于可比的放牧农场。强调了进一步开展流行病学工作的必要性。在这类工作中，血清学可能会有所帮助。
