Contribution to the Epidemiological Study on the Main Pathologies of Ruminants Declared in the Central Slaughterhouse of Jijel (Algeria)
Abstract
In order to assess the epidemiological situation of certain infectious and parasitic diseases of ruminants, a study was carried out in the central abattoir of Jijel on 625 animals (511 cattle, 74 sheep and 40 goats).
The results showed that the overall organ contamination rate by the pathologies studied was 17.12% with a higher prevalence rate for fasciolosis (12.32%) compared to other pathologies. In addition, the lungs are contaminated with abscess and hydatidosis (3.04% and 0.48%, respectively), whereas the liver is mainly affected by fasciolosis, abscess and hydatidosis (12.32%, 0.64% and 0.48%), respectively) and the kidneys are affected only by cysts (0.16%). In parallel, the liver is more contaminated (13.44%) compared to the lungs (3.52%) and the kidneys (0.16%). In addition, with the exception of two weak positive correlations between hydatidosis and temperature (r = +0.01689, R2 = +0.00029) and between abscesses and precipitation (r = +0.27335, R2 = +0.07472), other high positive and negative correlations were observed between the rest of the pathologies and mean values of temperature and precipitation. Therefore, it is necessary to implement an extension program of all stakeholders in the industry in order to avoid significant economic losses and preserve consumer health.
