Effects of a synbiotic combination of Bacillus subtilis and yeast cell wall-derived glucomannan on cecal colonization of Salmonella Enteritidis in layer chickens
Salmonella Enteritidis (SE) has been a major foodborne concern associated with poultry and poultry products. Direct-fed microbials (DFM), such as Bacillus subtilis strains, and mannan-oligosaccharides (MOS) added into poultry feed have emerged as an alternative approach to antimicrobials to reduce...

Effect of a synbiotic supplement as an antibiotic alternative on broiler skeletal, physiological, and oxidative parameters under heat stress
The aim of this study was to examine if synbiotics can function as alternatives to antibiotics in broiler production under heat stress (HS). Day-old broiler chicks (528 birds) were randomly placed in floor pens within 2 identical temperature-controlled rooms (11 birds/pen and 24 pens/room). The... Continue reading...
