This study was conducted to compare the relative resistance of crossbred Bos indicus X B. taurus Bonsmara and B. taurus Friesian cattle to Ixodes rubicundus (Karoo paralysis tick) infestations. During periods of peak abundance of the ticks, Friesian oxen harboured almost twice or more than twice as many ticks as either Bonsmara oxen or cows. During periods of low tick abundance tick burdens on both cattle breeds were closely similar. It is envisaged that cattle can play an important role in an integrated control strategy against the Karoo paralysis tick.
本研究旨在比较杂交牛（印度瘤牛×欧洲牛）邦斯玛拉牛和欧洲牛弗里生牛对红硬蜱（卡鲁麻痹蜱）侵袭的相对抗性。在蜱虫数量高峰期，弗里生公牛身上的蜱虫数量几乎是邦斯玛拉公牛或母牛的两倍或两倍以上。在蜱虫数量低的时期，两个牛品种身上的蜱虫负担非常相似。据设想，牛在针对卡鲁麻痹蜱的综合防治策略中可发挥重要作用。
