Abstract
Half-body tick collections, carried out on monthly intervals for ten months on naturally infested heifers belonging to four indigenous breeds (Abigar, Guraghe, Horro and Sheko) showed that the Horro and Guraghe breeds harboured significantly lower tick burden (mean count per month 12 ± 1.7) per month than the Sheko (mean count 16 ± 4.1) and Abigar (15± 3.4) breeds (P< 0.001). Counts of A. variegatumticks also showed significant differences between the Sheko and Horro breeds (P< 0.05), with the highest burden in Sheko and the lowest burden in Horro breed. The tick burden in all the animals was found to be mainly affected by season followed by breed. Upon assessment of the magnitude of IgG response to larval A. variegatumticks in the four breeds by indirect ELISA, significantly highest level of IgG against A. variegatum was found in Horro breed than the rest of the breeds (P< 0.05). The magnitude of IgG in the Horro breed was high during high infestation, while in the Sheko breed the level of IgG was lower during high infestation. The overall study shows that the Horro breed is relatively resistant, which might be a result of the higher IgG response in the serum compared to the Sheko breed, in which the low level of IgG might be responsible for consistently high tick burden.
