Mycotoxin contamination generally affects a large number of raw materials and finished feed intended for animal production. The economic impact on livestock production encompasses both, the cost of eliminating contaminated feed and the reduction in animal productivity. Therefore, the increase in veterinary care costs and technical efforts aimed at reducing mycotoxins negative effects. Cereals and by-products constitute the main ingredients of finished feed in production animals. Food processing affects mycotoxin distribution and concentration. The mycotoxin distribution in cereal processing procedures is a worldwide problem due to the high economic and health impacts. The use of a safe diet in which the risk of mycotoxin contamination can be minimized and the cost/benefit is accurately quantified should allow the maximization of herd productivity. The present review intends to address the problem of animal feed contamination describing the impact on animal health and productivity. Moreover, the economic impact generated by mycotoxins and their control in the animal feed industry was considered.
The objective was to evaluate the technological processing (protection strategies and storage conditions) influence on viability, on probiotic properties and adsorbent aflatoxin B1 capacity of ...S. boulardii RC009. Also, the yeast biological safety was evaluated. Lyophilisation (DL) and encapsulation + lyophilisation (EL) were conducted. Yeast protected with maltodextrin (M) or WPC stored at 4 °C reduced 1 and 2 log the viability, respectively. Yeast protected with M stored at 25 °C reduced 1 log after 70 d; with WPC the viability significantly reduced 3 log after 30 d. Technological processing improved the coaggregation’s capacity with pathogens and DL process allowed the greatest AFB1 adsorption. S. boulardii 106 cells/mL were no toxic to Vero cells (p˂0.05). Saccharomyces boulardii RC009 protected with M or WPC maintained viability after technological processing. It possesses a great capacity for AFB1 adsorption and probiotic properties and could be considered a candidate with proven safety for functional food products development.

•Commercial refinery syrup was a good substrate for Saccharomyces boulardii growth.•Maltodextrin and WPC were efficient protectors in ensuring the yeast viability.•The lyophilised yeast achieved high percentages of AFB1 adsorption.•Saccharomyces boulardii cells were non-toxic in Vero cells up to 106 CFU/mL.
The objective of the present study was to explore the influence of dietary supplementation with a mixed additive (MA) containing a probiotic and anti-mycotoxin (Saccharomyces cerevisiae RC016 and ...Lactobacillus rhamnosus RC007) and its interaction on the performance and health (biochemistry and liver/intestine histopathology) of broilers fed diets contaminated with aflatoxin B1 (AFB1) at 506000±22.1ng/kg. The MA contained S. cerevisiae RC016 (1×107cells/g) and L. rhamnosus RC007 (1×108cells/g) in relation 1:1. A total of sixty-one-day-old Cobb broilers were randomly allocated into four treatment groups with three replicates of 5 birds each for a five-week-old feeding experiment. The experimental diet for each treatment (T) was formulated as follows: T1, a commercial diet (CD); T2, CD+AFB1; T3, CD+0.1% MA; T4, CD+AFB1+0.1% MA. The MA improved (p<0.01) production parameters (weight gain, conversion rate, and carcass yield) and reduced (p<0.01) the toxic effect of AFB1 on the relative weight of the livers. In addition, the macro and microscopic alterations of livers and the possible intestinal injury related to histological damage in the presence of mycotoxin were reduced. The use of probiotic MA based on S. cerevisiae RC016 and L. rhamnosus RC007 in animal feed provides greater protection against mycotoxin contamination and is safe for use as a supplement in animal feed, providing beneficial effects that improve animal health and productivity. This is of great importance at the economic level for the avian production system.
El objetivo del presente trabajo fue estudiar la influencia de la suplementación dietética de un aditivo mixto (AM) de probióticos y antimicotoxinas, y su efecto sobre el rendimiento y la salud (bioquímica e histopatología de hígado/intestino) de pollos de engorde alimentados con una dieta contaminada con aflatoxina B1 (AFB1), a una dosis de 506.000±22,1ng/kg. El AM contenía Saccharomyces cerevisiae RC016 (1×107 células/g) y Lactobacillus rhamnosus RC007 (1×108 células/g) en una relación 1:1. Un total de 60 pollos de engorde (Cobb) de un día de edad se asignaron al azar en cuatro grupos de tratamiento con tres réplicas de 5 aves cada una, durante 5 semanas, a saber: T1, dieta comercial (DC); T2, DC+AFB1; T3, DC+0,1% AM; T4, DC+AFB1+0,1% AM. El AM mejoró (p<0,01) los parámetros de producción (ganancia de peso, tasa de conversión y rendimiento de la canal) y redujo (p<0,01) el efecto tóxico de la AFB1 sobre el peso relativo de los hígados. Además, se disminuyeron las alteraciones macro y microscópicas del hígado y la lesión intestinal posiblemente relacionada con el daño histológico en presencia de la micotoxina. El uso de probióticos y antimicotoxinas a base de S. cerevisiae RC016 y L. rhamnosus RC007 en la alimentación animal proporciona mejora la protección contra la contaminación por micotoxinas y es seguro para su uso como suplemento en la alimentación animal, con efectos beneficiosos que mejoran la salud y la productividad animal. Esto es de gran importancia en términos económicos para el sistema de producción aviar.
