“…Oxidative metabolism was assessed by the colorimetric technique of reduction of nitroblue latrazolium (NBT), as described by Choi, Kim, Cha and Kim (2006), adapted by Flores et al (2019). For this, the blood was refrigerated until it was processed within a maximum of 3 h after harvest.…”

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.

“…Supplementation with the autolyzed yeast decreased the lasting and recurrence of diarrhea, as well as the fecal score of calves in the second and third weeks of the experiment. Our previous studies demonstrated that S cerivisiae supplementation promote an immunomodulation around 15 days after supplementation in calves(Flores et al, 2019;Bertagnon et al, 2024).

Autolyzed yeast is a supplement option for calves due to its ability to stimulate the immune system and performance; however, there are few studies about the effect of different yeast derivatives. Autolyzed yeast is rich in immunomodulatory substances, such as mannan oligosaccharides and β-glucans. These substances enhance the innate and humoral immunity of calves, resulting in greater intestinal and respiratory health. Thus, the objective of the study was to evaluate whether supplementation with autolyzed yeast improves the health of calves, in the challenge of naturally acquired Eimeriosis and bovine respiratory disease (BRD). Twenty Holstein calves aged 15 days, which had already suckled colostrum, were studied for 36 days. At 15 days of life all animals had naturally acquired Eimeriosis. They were challenged with an intranasal BRD vaccine at 30 days of age. The Supplemented group (n=10) received autolyzed yeast (10 g animal -1 day -1), once a day in milk for 36 days, and the Control group (n=10) was not supplemented throughout the experiment. Blood neutrophil: lymphocyte ratio, oxidative metabolism of neutrophils (OM), serum immunoglobulins and haptoglobin, occurrence of diarrhea, BRD, and weight gain were measured. After vaccination, all animals increased the blood neutrophil: lymphocyte ratio, but only the control group showed a 20% reduction in OM three days after the vaccine. The supplement affected the immune response, preserving OM, increasing serum IgA levels by 10% (P=0.006), and reducing haptoglobin serum levels (P=0.05). In addition, the supplement attenuated diarrhea and BRD, which allowed for greater weekly weight gain (difference of 2 kg between treatments, P<0.05), concluding that the autolyzed yeast showed some evidence that it can increase the health of calves challenged with Eimeriosis and the BRD vaccine.

“…Saccharomyces cerevisiae é uma levedura benéfica aos animais, que pode ser usada com intuito de melhorar a performance digestiva e estimular a imunidade animal (Sanchez et al, 2014). Tem sido utilizada em suínos e aves com resultados expressivos na produtividade, o que motivou seu estudo em ruminantes seja em prol da produtividade como para aumentar a sanidade em geral (Flores et al, 2019;Sanchez et al, 2014). Saccharomyces cerevisiae pode ser usado como levedura íntegra, seja ela viva ou morta.…”

O complexo respiratório bovino (CRB) é uma afecção multifatorial, a qual pode afetar os animais de qualquer idade, tendo maior impacto em bezerras. O CRB é iniciado por uma infecção viral que facilita o surgimento de uma pneumonia bacteriana secundária, exacerbada. Os sinais clínicos incluem anorexia, prostração, aumento de temperatura 39.2°C, dispneia, sons respiratórios anormais e secreção nasal, podendo evoluir para morte. Eventos estressantes como o desmame, transporte e mudanças de lotes auxiliam no aparecimento da doença e na capacidade de responder aos tratamentos. Métodos comuns para conter o CRB, incluem vacinas, tratamentos com antibióticos e terapias auxiliares. Buscando a diminuição do uso dos antibióticos, as terapias auxiliares vêm ganhando espaço no mercado atual, e os produtos à base de Saccharomyces cerevisiae, se destacam por seus efeitos positivos sobre a função imunológica em bovinos, inclusive em bezerras neonatas que são imunologicamente imaturas, e que passam por períodos de desafios imunológicos como o CRB. Desta forma o objetivo do trabalho foi realizar uma revisão bibliográfica sobre a atuação da suplementação com Saccharomyces cerevisiae no complexo respiratório bovino.
