ABSTRACT The objective of this study was to investigate the effects of supplementation with the ethanolic extract of Myrciaria cauliflora peels and seeds on the performance and intestinal health of broilers inoculated with Salmonella Heidelberg and reared until 28 days old. Three hundred thirty-six one-day-old male broiler chickens were distributed in a completely randomized design with four treatments and seven replications each: NC – negative control, which received a 0.85% sterilized saline solution in the crop; EJ – group that […]

ABSTRACT This experiment was carried out to evaluate the effects of organic acids on the intestinal integrity and productive performance of broiler chickens experimentally inoculated with Salmonella Enteritidis. Additionally, Salmonella colonization levels in internal organs were evaluated. The study included 576 one-day-old CobbTM male broilers, distributed into eight treatment groups and six replicates. A completely randomized experimental design (encapsulated butyric acid × inoculation by Salmonella Enteritidis) was used. Poultry was orally inoculated with Salmonella Enteritidis in the first day (0 […]

Avaliaram-se os efeitos de Salmonella Enteritidis sobre a colonização e o desenvolvimento do trato intestinal, a conversão alimentar e o ganho de peso em perus. Um total de 135 perus de corte de 1 dia foi distribuído em três tratamentos: controle; perus oriundos de ovos inoculados com Salmonella Enteritidis via casca e perus desafiados com água de bebida com Salmonella Enteritidis. Aos 10, 20 e 28 dias, avaliaram-se as variáveis de desempenho e coletaram-se amostras para avaliação bacteriana, biometria e […]
