Correlation between Intestinal Health and Coccidiosis Prevalence in Broilers during Different Seasons of the Year in Brazil from 2012 to 2018

作者： Fabio Luis Gazoni Gabriela Miotto Galli Marcel Manente Boiago Lenita Moura Stefani Aline Zampar Marco A. Juárez-Estrada Guillermo Tellez-Isaias Aleksandro S. da Silva Animal Health and Reproduction Veterinary Medicine Graduate Program Federal University of Santa Maria (UFSM) Santa Maria Brazil Animal Science graduate Program Federal University of Rio Grande do Sul (UFRGS) Porto Alegre Brazil Animal Science graduate Program Santa Catarina State University (UDESC) Chapecó Brazil Departamento de Medicina y Zootecnia de Aves Facultad de Medicina Veterinaria y Zootecnia Universidad Nacional Autonoma de Mexico Ciudad Universitaria Ciudad de Mexico Mexico Department of Poultry Science Division of Agriculture University of Arkansas Fayetteville AR USA

Coccidiosis is a disease caused by intracellular protozoan parasites, specifically belonging to the genus Eimeria. These parasites target the gastrointestinal tract in different types of hosts, causing sores in the intestinal lining. The presence of these lesions reduces the animal’s ability to digest and absorb nutrients, significantly impacting their overall performance. The current study aimed to explore the potential correlation between seasonal variations and the incidence of Eimeria spp-induced lesions in broiler chickens’ gastrointestinal tracts in Brazil from 2012 to 2018. A total of 8,607 broiler chickens, aged 14 to 42 days, were sampled from 103 poultry integrated companies in Brazil to conduct intestinal health examinations. The sampling process involved selecting 3 to 6 chickens from each poultry house for examination. The assessment included various abnormalities such as shedding of intestinal cells and excessive fluid and mucus presence, thickening and tension of the intestines, food movement, roughened mucosal surface resembling a Turkish towel in the small intestine, tissue death, duodenal inflammation, intestinal inflammation, gizzard erosion, presence of worms and bedding material, and ingestion of mealworms. During the seasons, winter exhibited the highest average occurrence of Eimeria maxima microorganisms at 52.83%, with E. acervulina following closely at 26.42% in second place. In spring, E. maxima had an occurrence of 11.31%, while in fall, E. tenella had the lowest occurrence at 6.74%. When analyzing the seasonal occurrence of Eimeria, it was observed that E. maxima micro was more common during winter compared to summer (P = 0.0491). However, no discernible variation was observed in the occurrence of the remaining species across different seasons. Research findings suggest that subclinical coccidiosis is most prevalent during the winter season in Brazil. Likewise, clinical disease caused by E. acervulina is also prevalent during this time. I
