Situation of gastrointestinal endoparasites in ruminants in an agropastoral region of Algeria (Djelfa): ocurrence and influence of risk factors

The objective of the present work was the research and identification of gastrointestinal endoparasites in ruminant livestock, as well as the study of the influence of certain risk factors on the prevalence of the endoparasites that have been identified. This study was carried out over a period of 8 months from October 2023 to May 2024 and on 300 fecal samples (100 cattle, 100 sheep and 100 goats). Coprological analyzes will be carried out using the flotation technique and the observation was made by an optical microscope. The results obtained showed that the overall infection rate is 47.67%. Depending on the parasites sought, the prevalences of Fasciola hepatica (F. hepatica), Eimeria spp., Strongyle eggs, Nematodirus spp., Dicrocoelium spp., Moniezia spp. were 0, 26.33, 15.33, 4.33, 0.67 and 1% respectively. Statistical analyzes showed a clearly significant difference (P < 0.001) between the animal species for Strongyle eggs and a non-significant difference between the three animal species for the other parasites (P > 0.05). This results reflect the high prevalence of certain endoparasites in the three animal species studied, which constitutes a major risk to health and the level of animal production. In this case, the need to find adequate control measures against these parasitic diseases is mandatory in order to reduce its harmful impacts and preserve animal health.
