Resumo: | Saccharomyces cerevisiae is a supplement option for ruminants due to its ability to stimulate the immune system and productivity; however, there are few studies that demonstrate the effectiveness of this yeast in dairy cattle, especially regarding its effect on milk phagocyte function. Thus, this study examined the effect of two presentations of autolyzed S. cerevisiae on milk phagocyte function and milk production in healthy Holstein cows from the third to the fifth months of lactation with somatic cell count (SCC) less than 200,000 cells mL-1. Ten animals received cell wall-rich S. cerevisiae autolysate (WC 15 g animal day-1); 8 received the cytoplasm-rich extract (CYT 5 g animal day-1) and 7 received a diet without supplementation (C, control) for 60 days. Weekly oxidative metabolism analysis of milk leukocytes, production and milk constituents was carried out. The oxidative metabolism of milk leukocytes was higher in the WC group than in the C group between D32 and D48 (P≤ 0.05) and in the CYT group than in the C group between D24 and D40 (P≤ 0.05). The production and percentage of milk fat increased in CYT at D48 and D56. It is concluded that the CYT group had a greater effect on productivity, while on immunity the effect was intermediate, compared to the WC group, which was efficient in improving the immunity of the mammary gland. |

Assim, o efeito de duas apresentações de S. cerevisiae autolisado na função fagocitária do leite e produção de leite de vacas da raça Holandes saudáveis entre o terceiro e quinto mês de lactação, com CCS inferior a 200.000 células mL -1. Para tanto, 10 animais receberam autolisado de S. cerevisiae ricos em parede celular (WC - 15 g animal dia-1); oito receberam o extrato rico em citoplasma (CYT - 5 g animal dia-1) e 7 receberam dieta sem suplementação (C - controle) por 60 dias. Análises do metabolismo oxidativo de leucócitos lácteos, produção de leite e constituintes do leite foram realizadas semanalmente. O metabolismo oxidativo dos leucócitos lácteos foi maior no grupo WC do que no grupo C entre D32 e D48 (P≤ 0,05) e no grupo CYT do que no grupo C entre D24 e D40 (P≤ 0,05). A produção de leite e a porcentagem de gordura do leite aumentaram no citoplasma (CYT) em D48 e D56. Concluiu-se que o grupo CYT teve um efeito maior na produtividade enquanto que na imunidade o efeito foi intermediário, comparando ao grupo WC que se mostrou eficiente na melhora da imunidade da glândula mamária.UEL2023-06-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4702910.5433/1679-0359.2023v44n2p705Semina: Ciências Agrárias; Vol. 44 No. 2 (2023); 705-720Semina: Ciências Agrárias; v. 44 n. 2 (2023); 705-7201679-03591676-546Xreponame:Semina.
