Resumo: The objective of this study was to evaluate whether the administration of two classes of Saccharomyces cerevisiae improved the health of feedlot-finished steers. A total of 33 Angus-Nellore blood ½ steers (body weight of 350 ± 10 kg and 11 ± 5 months old) fed an energy diet were evaluated at the beginning (0 and 16 days), middle (44 and 72 days), and end (100) of the feedlot based on the inflammatory status and health of the respiratory and digestive tracts. Inflammation and innate immunity were measured using leukocyte oxidative metabolism (OM), serum haptoglobin levels, and the neutrophil-to-lymphocyte ratio. Respiratory health was verified based on nasal secretion, rectal temperature, and lung lesions during slaughter. The digestive health was verified by histomorphology of the rumen and intestine. The treatments were as follows: Saccharomyces cerevisiae in culture (CUL n=12), S. cerevisiae in the autolyzed form (AUT n=10), and control diet (CON, n=11). In the CUL group, OM increased by 7% on average, with lower indicators of respiratory disease and inflammatory status in the intermediate and final stages of the feedlots. The ruminal papillae of these animals were 30% thinner than those of the CON group and had lower ruminitis scores. Although AUT promoted a 10% increase in OM and a lower inflammatory status in the intermediate and final stages of the feedlot, steers showed more indicators of respiratory diseases than those in the CUL group. The duodenal villus area and jejunal villus height in the AUT group still increased by 25 and 15%, respectively. Its effect on the ruminal papilla was subtle, only decreasing the ruminitis score. We concluded that both groups of S. cerevisiae improved the health of animals compared with the control group, indicating that supplementation with S. cerevisiae cultures resulted in the decreased alteration of rumen papillae, compatible with a lower occurrence of subclinical ruminal acidosis syndrome (SARA), reflecting immunological gains and a lower occurrence of bovine respiratory disease (BRD). The S. cerevisiae autolysate showed a higher intestinal effect and lower activity in the rumen papillae. Although this treatment showed an immunological gain similar to a yeast culture, it reflected the lower health of the respiratory tract.

Um total de 33 novilhos ½ sangue Angus-Nelore, (350 ±10 kg peso vivo e 11± 5 meses de vida) alimentados com dieta energética foram avaliados no início (0 e 16 dias), meio (44 e 72 dias) e final (100) de confinamento, por meio de indicadores de inflamação e saúde do trato respiratório e digestório. A inflamação e imunidade inata foram aferidas por metabolismo oxidativo de leucócitos (MO); teores séricos de haptoglobina e razão neutrófilo:linfócito. A saúde respiratória foi verificada por secreção nasal, temperatura retal e lesões pulmonares no abate. E a saúde digestória foi verificada por histomorfologia do rúmen e intestino. Os tratamentos foram: Saccharomyces cerevisiae na forma de cultura (CUL n=12), S. cerevisiae na forma autolisada (AUT n=10) e dieta controle (CON n=11). O CUL apresentaram incremento médio de 7% no MO, menores indicadores de doença respiratória e de status inflamatório na fase intermediária e final do confinamento. As papilas ruminais destes animais era 30% mais delgada que o CON, e apresentavam menor escore de ruminite. Apesar do AUT promover incremento de 10% no MO e menor status inflamatório na fase intermediária e final do confinamento também, os novilhos apesentaram mais indicadores de doenças respiratórias que o CUL. O AUT ainda aumentou 25% da área de vilosidade de duodeno, e 15% na altura da vilosidade jejunal. Sua ação em papila ruminal foi tênue, minimizando apenas o escore de ruminite. Concluiu-se que ambas as classes de S. cerevisiae aumentaram a saúde dos animais em relação ao CON, destacando-se a suplementação com cultura de S. cerevisiae, que resultou em menor alteração de papilas ruminais compatíveis com menor ocorrência de SARA, melhores resultados do sistema imunológico e menor ocorrência de CRB. O autolisado de S. cerevisiae demonstrou maior efeito intestinal, com atuação de menor impacto em papila ruminal. E apesar de ter ganho imunológico similar ao encontrado ao CUL, apresentou menor influência na saúde do trato respiratório. UEL2023-09-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4797710.5433/1679-0359.2023v44n4p1321Semina: Ciências Agrárias; Vol. 44 No. 4 (2023); 1321-1340Semina: Ciências Agrárias; v. 44 n. 4 (2023); 1321-13401679-03591676-546Xreponame:Semina.
