Agentes parasitários em cama de aviário não reutilizada em criação avícola caipira

Abstract

The objective of this study was to identify parasitic agents in poultry litter not reused in poultry farming in the municipality of. For this purpose, 20 avian litter samples collected from a hickory poultry farm belonging to an agricultural family school were analyzed. The samples were processed by flotation techniques with saturated sodium chloride solution and spontaneous sedimentation. Helminths of the genera Ascaridia (n = 16; 80%), Strogyloides (n = 14; 70%) and Heterakis (n = 9; 45%) and protozoa of the genus Eimeria (n = 20; 100%) were identified. Eimeria sp. was the most frequent parasitic agent, however, although parasitized, the birds show resistance, probably because they are loose, free of stress or have a low infection rate. It is concluded that a great diversity of parasitic agents infect the evaluated birds and these are eliminated with the feces being deposited in the bed. To minimize the problem, good sanitary and hygienic management practices are necessary, eliminating sources of transmission for subsequent bird lots. It is recommended the implementation of the parasitological diagnosis as an adequate tool to assist in the control of parasitoses in this breeding.
