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 ...

This trial was done to determine broiler live performance to 42 days, under a hot climate in India. 2080 VenCobb 400 broilers were allocated in 4 groups with 26 birds per floor pen and 20 replicates per group: negative control group (NC), positive control group (PC), direct-fed microbial group (DFM) at Log 5 CFU/g of feed and Bacitracine group (BMD) at 500 g/T of feed. The DFM product was composed ...

Salmonella Enteritidis is a significant foodborne pathogen that can often be traced back to poultry and poultry products. Feed ingredients such as Bacillus probiotics and parietal yeast fractions have gained in interest to reduce food safety issues. Consequently, 2 in vivo trials were setup to evaluate the ability of these products to reduce Salmonella Enteritidis colonization in th ...

Two of the strains, B amilolyquifaciens and B pumilus, in the Microsaf probiotic mix indeed have bile salt hydrolase activity. With respect to your question, if presence of this activity would influence broiler production yield when feeding a diet with acid, we speculate that this is not the case like for the lactobacilli having this activity. The bacilli in the Microsaft mix are all treated with ...

Abstract
Since the ban of using antibiotic growth promoters (AGPs) in livestock in several countries, probiotics have been considered as possible alternative. Spore forming bacteria that belong to Bacillus species are one of those probiotics selected for their ability to resist adverse environmental and nutritional conditions such as, low pH in the stomach and high temperature of the feed manufac ...

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 ...
