Effet du parasitisme interne sur la productivité des pintades locales au Burkina Faso
Abstract
Effect of Endoparasitism on the Local Production of Guinea Fowl in Burkina Faso. The objective of this study was to identify endoparasites and compare endoparasitic infestations, mortality, growth weight, reproductive groups of guinea fowl dewormed with poultry polyvalent vermifuge (PPV) and non dewormed guinea fowl, kept in extensive mode in rural areas in two villages in the province of Houet, Matourkou and Samagan in Burkina Faso. The results showed that 41.9% of fowl were infected and that Eimeria always persisted even among birds dewormed. The parasites the most encountered were Eimeria (46.6%), Ascaridia spp. (22.4%), Hymenolepis carioca (7.1%) and Rallietina spp. (7.7%). The OPG in simple forms of infection ranged from 0 to 700 for all species of pests but reached 13 600 for Eimeria. The OPG from 400 to 11 000 marked the infections for 2 and 3 types of parasites. The mortality rates were 20% in dewormed and 33.05% for non dewormed. At 32 weeks of age, the average weight of dewormed fowl compared with non dewormed males were, 1205 g vs. 965 g, females, 1251 g vs 1085 g. Parasitism showed itself harmful from the 2nd week. The dewormed fowl entered into laying to 168 days of age against 182 days for non dewormed. In eight weeks of laying, the dewormed female has laid eggs averaged 46.2 against 33.4 for female eggs non dewormed, with average weights of 37.0 g and 36.15 g respectively. Deworming of guinea fowl in PPV from young age to adulthood significantly improves productivity.
