L’influence des parasites gastro-intestinaux sur les paramètres sanguins chez les bovins dans la région de Sétif

Abstract

This study was conducted in the Setif region between March and June 2025, with the aim of detecting intestinal parasites and evaluating their impact on hematological parameters in cattle. Among the 60 cattle examined, a high parasitic infestation rate of 86.66% was recorded, highlighting a strong parasitic pressure in the area. The distribution of infestation cases varied by locality, with the highest prevalence observed in Bougaâ and Hammam Sokhna (28.85% each), followed by Aïn Oulmène (23.07%) and Beni Aziz (19.23%). Adults (61.66%) were more affected than young animals, and infestation was slightly more common in extensive farming systems (51.92%). Crossbred cattle were more represented among the infested animals (50%). Coprological analysis revealed a high diversity of parasites, with Moneizia sp (48.33%), Toxocara vitulorum (35%), and Cooperia spp (26.70%) being the most frequently identified. Cases of fascioliasis (Fasciola hepatica, 11.70%) and coccidiosis (Eimeria sp, 10%) were also reported. Polyparasitism was common, reflecting the complex parasitic burden in the region. Hematological evaluation showed good agreement between manual and automated methods, with similar values observed for red and white blood cell counts and erythrocyte indices. The values obtained were generally within physiological ranges, and the manual method proved to be reliable, particularly in resource-limited settings. These findings emphasize the importance of integrated parasitic surveillance and prevention strategies that consider geographic, zootechnical, and genetic factors
