1. IntroductionDeoxynivalenol (DON) is a secondary toxic metabolite mainly produced by Fusarium species that belongs to the trichothecenes family. DON frequently occurs in cereals, including wheat, maize, barley, rye and oats [1]. A 10-year survey from 2008 to 2017 of the global mycotoxin occurrence in feed revealed that DON was the most prevalent of mycotoxins and was detected in 64% of 74,821 sa ...

Yeast cell wall (YCW) fractions have proven effective in reducing the incidence of necrotic enteritis induced by Clostridium perfringens. Dietary supplementation with YCWs stimulates the systemic innate immune responses of broiler chickens, suggesting the role of these products in regulating immune homeostasis (Alizadeh et al., 2016). In a proposed mode of action of YCW on bacteria, the branched l ...

To provide in vitro evidences on the antimicrobial effect of yeast cell wall (YCW), the effectiveness of YCW fractions in inhibiting the growth of several C. perfringens strains was quantitatively determined. The bacterium was grown in the presence of different YCW fractions at different concentration levels. The effect of YCW fractions on the growth parameters was analyzed. One product out of fou ...

Ruminants have a unique digestive physiology characterized by a pre-systemic fermentation and digestion of plant constituents such as cellulose by microorganisms comprising the ruminal flora. This particularity requires feeding regimes that include enough amounts of forage to maintain a functional rumen flora. Then ruminant nutrition consists to equilibrate diet with fiber, energy and protein in o ...
