Influence of goat physiological state and season on prevalence and gastrointestinal parasite load in Benin
Abstract
Gastrointestinal parasitic diseases have a major economic and zootechnical impact, undermining the productivity of goat farms in tropical environments. This study assessed the influence of different physiological stages and seasons on the prevalence and load of gastrointestinal parasites in goats on traditional farms in Benin. To achieve this objective, sampling and coproscopic analysis at different physiological stages of goats and at different seasons of the year were carried out in different departments of Benin. The results showed that goats were mainly infested with Strongyles and Strongyloides spp. Pregnant goats followed by lactating subjects were the most infested. Both parasites were more prevalent in pregnant goats (91.7 % Strongle and 88 % Strongyloides), followed by lactating goats (88.4 % Strongle and 87 % Strongyloides) and growing goats (86% Strongle and 85.1% Strongyloides). Parasitic loads of strongyles, strongyloides, Moniezia and coccidian ocysts were higher in the rainy season than in the dry season. It would therefore be wise to pay close attention to the health status of animals during the gestation and lactation stages, which are the most vulnerable, particularly during the rainy season.
