In recent years, the market positioning for a reduction on antibiotic use in animal production gained strength with a focus to produce antibiotic free livestock. In this context mannan-oligosaccharides (MOS) have conquered the animal health industry. MOS could function as potential alternatives in a strategy for antibiotic reduction and substitution and help the animals to maintain their productiv ...

Abstract An experimental direct-fed microbial (DFM) was evaluated in a dose- response trial to determine broiler live performance to 42 d with Coccivac® B at placement (d 0), used litter on d 4, and toxin-producing Clostridium perfringens (Cp) challenges on d 17-18 (by oral gavage and via water trough daily). There were 8 dietary treatment groups with 10 replicate pens of 30 chicks each per t ...

Abstract Necrotic enteritis (NE) caused by Clostridium perfringens (CP) is a devasting bacterial disease responsible for economic losses, by increasing mortality because of damage to the broiler small intestine. Since ban of antibiotics use as growth promoters (AGPs) in some markets like in Europe and no antibiotic ever programs (NAE) in U.S., economic losses have become more prevalent. To preven ...

Abstract Many species of Bacillus are used as probiotics in animal feed not only due their proven effect on health and performance of animals, but also the resistance of the spores to the high temperature of the feed manufacturing process. After the spore is ingested by the host it needs to germinate to be metabolically active and provide a benefit to the animal. The germination time of a spore v ...
