Avaliação Parasitológica da cama de frango reutilizada em uma granja de Paço do Lumiar-MA

Abstract

Brazil is considered a major producer and global exporter of chicken meat, having an organized production in an integrated system, producer and agro processing industries. However current intensive production systems facilitate the multiplication of pathogens due to high population density and short production cycle. But so there is the reuse of poultry litter is essential that it be subjected to appropriate management so that there is the destruction of microorganisms. Thus the present study aimed to evaluate the quality of reusable poultry litter in the Paço do Lumiar-MA city, identifying the presence or absence of parasites. Poultry litter samples were collected for parasitological evaluation. For analysis, we used the methods of spontaneous sedimentation, Sheather method, Sporulation for diagnosis of oocysts of coccidia, Sporulation and Necropsy. Eggs and larvae were found in some of the genre endoparasites Ascaridia, Strongyloides, Heterakis, and Trichuris also looking up the presence of mites. For the analysis of the data, a simples statistic was used, being nematode eggs of the genera Strongyloides (72%), Ascaridia (10%) and Heterakis (18%). Among larvae, Ascaridia was the most prevalent, with 97% of cases, followed by Strongyloides (1%) and soil larvae (2%). A total of 4900 Eimeria oocysts were also found, among them 1200 in sporulation state. No changes were observed during necropsy. Ectoparasites were also found, such as mites and chicks (Alphitobius diaperinus). It is concluded that the high frequency of parasites found in chicken litter may be related to management failure, and it has been used in previous batches
