Resumo: | Mycotoxins often contaminate cattle food, which can cause liver damage, immunosuppression, and reduced milk production. Although previous studies have shown the benefits of adsorbents in farm animals, knowledge regarding their mechanism of action is limited, especially when intoxication occurs due to naturally contaminated diets. The present study aimed to assess whether the daily oral administration of mycotoxin adsorbent bentonite clay based on aluminosilicate for 56 days, would attenuate these changes in 18 dairy cows, which were multiparous in the middle of the lactation stage, and were consuming a diet containing fumonisin B1 and B2, zearalenone, and desoxynivalenol. The animals were divided into treatment (TG, n = 9) and control (CG, n = 9) groups, and subjected to assessment of liver functions, hematological assessments, assessment of oxidative leucocyte metabolism by the tetrazolium nitroazul (NBT) technique, and physical chemical analysis of milk, every week for two months, totaling eight analyses. It was observed that the use of the adsorbent caused a reduction in the milk excretion of aflatoxin M1 (AFM1), an increase in levels of serum protein (p = 0.03) and albumin (p = 0.0001), an increase in leukocyte oxidative metabolism from day 24 of treatment(p = 0.05), and increased milk production from the day 16 of treatment (p = 0.08). There was no improvement in the physicochemical indices of the milk. It was concluded that the use of an aluminosilicate-based adsorbent was able to attenuate the effects of mycotoxins on the function of leukocytes and increase milk production. |

Embora existam estudos mostrando os benefícios de adsorventes em animais de produção, há limitado conhecimento sobre sua ação quando a intoxicação de bovinos ocorre por dietas naturalmente contaminadas. O presente estudo objetivou avaliar se a administração oral diária do adsorvente de micotoxinas, argila bentonita a base de aluminossilicato durante 56 dias atenuaria alterações promovidas pelas micotoxinas em 18 vacas leiteiras, multíparas no meio do estágio da lactação, consumindo dieta contendo fumonisina B1 e B2, zearalenona (ZEA) e desoxinivalenol (DON). Os animais foram divididos, grupos tratamento (GT, n=9) e controle (GC, n=9), e submetidos às avaliações de enzimas e função hepática, hematológicas, metabolismo oxidativo de leucócitos pela técnica do nitroazul de tetrazolium (NBT) e análise físico-química do leite, a cada semana, durante dois meses, totalizando oito análises. Observou-se que o uso do adsorvente promoveu redução da excreção láctea de aflatoxina M1 (AFM1), aumento de proteína (p = 0,03) e albumina séricas (p= 0,0001), e aumento do metabolismo oxidativo leucocitário a partir do dia 24 (p = 0,05). Houve também elevação da produção leiteira a partir do 16º dia de tratamento (p= 0,008). Não foi observado melhora nos índices físico-químicos do leite dos animais e houve pouca influência na atividade das enzimas hepáticas. Conclui-se que o uso do adsorvente a base de aluminossilicato foi capaz de atenuar os efeitos das micotoxinas na função de leucócitos e de elevar a produção leiteira.UEL2021-08-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4350910.5433/1679-0359.2021v42n6p3337Semina: Ciências Agrárias; Vol. 42 No. 6 (2021); 3337-3354Semina: Ciências Agrárias; v. 42 n. 6 (2021); 3337-33541679-03591676-546Xreponame:Semina.
