The production of livestock and poultry faces major challenges to meet the global demand for meat and dairy products and eggs due to a steady increase in the world’s population and the ban of antibiotics in animal production. This ban has forced animal nutritionists to seek for natural alternatives to antibiotics. In this context, the yeast Saccharomyces cerevisiae has received considerable attention in the last decade. It has been reported that feed supplementation with live yeast cells improve feed efficiency, enhance feed digestibility, increase animal performance, reduce the number of pathogenic bacteria, improve animal health and reduce the negative environmental impacts of livestock production. The current review sheds light on the effects of the use of live S. cerevisiae cells in the diets of nonruminant and pseudo‐ruminant’s animals and the mechanisms by which they exert its effects. This review work revealed that the addition of S. cerevisiae in poultry feed causes a phenomenon called competitive exclusion of pathogenic bacteria capable of causing disease adhere to the yeast surface, and so removing a large amount of harmful micro‐organisms and allowing the Animal defend more effectively, the production of antimicrobial agents, the balancing the gut microbiota and stimulation of host adaptive immune system and improving gut morphological structure, thus these benefits are reflected on the overall poultry health. In addition, in the presence of live S. cerevisiae cells, the immunity of rabbits was improved due to the high number of white blood cell. In addition, apparent digestibility of acid and neutral detergent fibre was improved in horses and rabbits. Saccharomyces cerevisiae in pig diets augment mucosal immunity by increasing IgM and IgA activity against pathogens, enhance intestinal development and function, adsorb mycotoxins, modulate gut microbiota and reduce postweaning diarrhoea.

“…The removal of AFs from contaminated diet and feedstuffs still represents a great problem which needs more investigation to find effective decontamination technologies (Assar, Attia, & Eid, 2018;János, Sándor, Zsanett, Csaba, & Beáta, 2010). Various strategies for mycotoxin detoxification including physical, chemical and biological approaches have been used (Çelýk, Denlý, & Savas, 2003). The use of feed additives which have the ability to bind and detoxify mycotoxins provides promising alternatives (Geetha & Chakravarthula, 2018;Murugesan et al, 2015).…”

| INTRODUC TI ONMycotoxins are secondary toxic metabolites of the fungi that grow on feedstuffs in the field or during their storage, and they are known to cause health problems or death if ingested by human or animals (Qazi & Fayyaz, 2006). Aflatoxins (AFs) produced by the fungi, Aspergillus flavus and Aspergillus parasiticus, are considered one of the most toxic metabolites which contaminate feed and feed ingredients all over the world. In farm animals including rabbit which represents one of the most sensitive species to AF toxicity, the consumption of diets contaminated with AFs resulted in anorexia, decreased feed intake, altered feed utilization, reduced weight gain, inhibited growth, immune suppression, increased susceptibility to different stressors and diseases and increased mortality rate, altered reproductive AbstractThe present experiment was conducted to evaluate the effect of dietary supplementation with some feed additives (potassium sorbate; Sor, hydrated sodium calcium almuniosilicate; Hsc and L-methionine; L-M) against aflatoxin B1 (AF) toxicity in rabbits. A total of 72 growing rabbits (5-week-old) were distributed into six equal groups (4 replicates with 3 rabbits each). The experimental groups are as follows:control group, AF group (supplemented with AF 0.3 mg/kg diet), AF + Sor group (AF 0.3 mg/kg diet + Sor 2 g/kg diet), AF + Hsc group (AF 0.3 mg/kg diet + Hsc 5 g/kg diet), AF + L-M group (AF 0.3 mg/kg diet + L-M 8 g/kg diet) and AF + Mix group (AF 0.3 mg/kg diet + 2 Sor + 5 Hsc + 8 L-M g/kg diet). Live body weight and weight gain at 13 weeks of age were significantly reduced by AF. Feed intake at 13 weeks of age was decreased in AF, AF + Hsc and AF + Mix compared to the control. AF, AF + Hsc and AF + Mix showed the lowest total antioxidant capacity compared to the control.The highest level of reactive oxygen species and 8-Hydroxy-2-desoxyguanosine was observed in AF group. Using of other supplements with AF increased immunoglobu-linM than AF alone. In conclusion, dietary supplementation of Sor, L-M, Hsc or their mixture was effective in reducing the adverse effects of AF on performance, antioxidant and immune status of rabbits with more better improvement obtained by Sor or L-M separately.

“…The supplementation of whole yeast and only yeast cell wall rather [53,112,123] have shown a reduction in mycotoxins toxicities, indicating possible stability of the yeast-mycotoxins complex along the gastrointestinal tract. The cell wall represents about 30% of total weight of yeast cell [112].…”

Mycotoxins - Impact and Management Strategies

View full text Add to dashboard Cite

About 25% of total agriculture products are contaminated with aflatoxins (AFs) and other mycotoxins in the world especially in Africa, Asia and Latin America, completely losing about 2-3% of food values and thus causing economic losses to farmers. The mycotoxin contaminations of food supply chain impact on human and animal health primarily, whereas production is the second major concern especially in developing countries. Aflatoxins (colorless to pale yellow colored crystals) are the most studied (>5000 research articles) group of mycotoxins. AFs impose major problems regarding health, growth, FCR (feed conversion ratio), etc. in the subtropical zone. In the agricultural commodities, the prevention of fungal contamination during plant growth, harvesting and storage seems to be the most effective and rational precautionary measures to avoid mycotoxins. Activated charcoal; aluminosilicates; polymers, such as polyvinyl pyrrolidones and cholestyramine; and yeast, yeast-based products, and humic acid have been studied extensively with promising but variable results. A live yeast, named Saccharomyces cerevisiae (S. cerevisiae), has also been observed to lighten the adverse effects of aflatoxicosis in poultry. These beneficial effects were later attributed to glucomannan, being derived from the cell wall of S. cerevisiae.
