ABSTRACT

The present investigation was carried out during May-November 2016 to examine the prevalence of ticks in cattle at Government Livestock Experimental Farm Fazilpur, District Rajanpur. During the present study 600 cattle were examined and the following genera of ticks were recovered; Hyalomma (47.33%), Dermacentor (6.16%), Amblyomma (1.83%), Rhipicephallus (2%), Boophilus (2.5%) and Ixodes (3.16%). Results regarding the relationship between sex and ticks infesting cattle showed that Dermacentor (16.20%), Amblyomma (7.62%), Rhipicephallus (7.62%), Boophilus (4.23%) and Ixodes (5.08%) were more prevalent in male animals, whereas prevalence of Hyalomma was highest (52.69%) in female animals. Age wise prevalence showed that the Hyalomma was highest (61.70%) in age group of 37-72 months while the prevalence was lowest (20%) in age group of 109-144 months. The highest prevalence of Dermacentor (12.76%), Amblyomma (4.25%), Rhipicephallus (4.25%) was in age group of 73-108 months while prevalence of Dermacentor (2.97%), Amblyomma (0.85%), Rhipicephallus (0.85%) was lowest in age group of 37-72 months. The highest prevalence of Boophilus (7.5%) and Ixodes (12.5%) was in age group of 109-144 months while lowest prevalence was recorded for Boophilus (1.70%) and Ixodes (1.27%) in age group of 37-72 months. The relationship between body weight and ticks infesting cattle showed that the prevalence of Hyalomma was highest (57.29%) in body weight group of 101-200kg while the prevalence was lowest (26.08%) in body weight group of 50-100kg. Dermacentor (13.04%), Amblyomma (4.34%), Rhipicephallus (4.34%), Boophilus (6.52%) and Ixodes (10.86%) were more prevalent in body weight group of 50-100kg. The difference was statistically significant (P<0.05). Key words: cattle, ticks, prevalence age, sex
