Contribution of the prophylactic campaigns of sheep flocks in preserving animal health in the Wilaya of Djelfa

Sheep pox is the main infectious disease that worries sheep farmers in Algeria; because of its significant economic cost. Despite this, prophylactic campaigns through vaccination remain the only way to preserve animal health. In this study, the methodology consists of analyzing the data collected from reports of vaccination operations, which has very particular importance due to the massive adhesion of breeders to these campaigns. This analysis is directly related to the sheep vaccinated compared to the numbers of adhered breeders, which enabled us to highlight an upward trend. This leads to a conclusion that every year new breeders are taking the vaccination programs against sheep pox. The climatic factor, in particular the precipitation, of which the strong averages generate important grasses pushes in favor of regrouping herds, which increases the possibility of propagation of the sheep pox virus. This analysis has given a negative correlation between the ratio and the precipitation. The latter is weaker when the precipitation tends to increase, thus pushing breeders to seek veterinary services for the vaccination of their herds. From the above, it clearly emerges that the innovative study of the precipitation effect on the importance of the farmers' adhesion flow to vaccination programs is an essential element, which conditions the movements and regrouping of herds in Algeria.
