Abstract

Five different breeds of cattle namely pure Hereford, Hereford x Kedah-Kelantan, Friesian x Kedah-Kelantan, Brahman x Kedah-Kelantan and pure Kedah-Kelantan were used in the tick resistance study. Each animal was infested with 40,000 larvae Boophilus microplus which were cultured in the laboratory. Tick resistance of the individual animal was assessed by the number of engorged tick produced, by the weight of tick of the weight of eggs produced by the ticks. The naturally detached engorged female ticks were collected daily starting from day 18 up to day 26 after the application of larvae, until there were no more detached ticks present. The results of this study showed a very significant breed differences (P < 0.01) in tick resistance. The pure Kedah-Kelantan and their crossbreds appeared to be highly resistant as compared to pure Hereford. The former produced a range of 0.7 to 4.2 percent of applied larvae, whereas the latter produced a range of 17 to 28 percent. Among the crossbreds the Hereford x Kedah-Kelantan produced significantly higher number of ticks as compared to pure Kedah-Kelantan and Brahman x Kedah-Kelantan. The differences between tick resistance among the breeds shown in this study seemed to have no effect on the tick weight and eggs produced by the ticks.
