Mannanoligosaccharides or flavomycin in turkeys diets: effect on mucosa-associated microflora and growth performance

Abstract

Maintaining gut health and well balanced intestinal microflora is important for the profitable production of high quality poultry. We investigated the impact of mannanoligosaccharides (MOS) in comparison with flavomycin on turkeys performance and intestinal colonization by harmful and beneficial microflora. Two hundred forty turkeys (four replicates of 12 birds per treatment) were fed on diet supplemented with flavomycin (8 mg/kg feed) or with low (1g/kg feed during the entire study), medium (4 and 2 g/kg feed in the first and second 8-week periods, respectively) and high (10 and 4 g/kg feed in the first and second 8-week periods, respectively) level of MOS. Basal diet without supplements was applied as control. After 16 weeks of feeding, the animals were sacrificed and microbial populations (Bifidobacterium, Lactobacillus, streptococci, Escherichia coli and other enterobacteria) attached to the colonic epithelium were assessed. Moreover, colonic epithelia were washed to remove the bound microorganisms and examined for their susceptibility for colonization by exogenous probiotic and pathogenic strains in vitro. In all experimental groups the reduction of the bacteria attached to the epithelium was found, except for increase of streptococci in flavomycinreceiving group and bifidobacteria in flavomycin and MOS-receiving groups. Higher doses of MOS had stimulating effect on body weight gain. In vitro studies revealed a great potential of MOS to reduce attachment of enterobacteria and in higher doses to enhance adhesion of Bifidobacterium and selected Lactobacillus strains (P<0.05).

Effects of Flavomycin, <i>Bacillus licheniformis </i>and Enramycin on Performance, Nutrient Digestibility, Gut Morphology and the Intestinal Microflora of Broilers

“…During the grower phase and over the entire experimental period, only the FCR in birds fed the combination of Flavomycin and Bacillus licheniformis or the Enramycin diet was improved indicating that Flavomycin combined with Bacillus licheniformis and Enramycin has a greater effect on broiler performance than Flavomycin fed alone. The lack of a response in ADG and ADFI is consistent with previous findings for broiler chickens or turkeys ( Mohamed et al , 2008 ; Haque et al , 2010 ; Wasilewska et al , 2010 ).…”

Yogurt starter cultures of Streptococcus thermophilus and Lactobacillus bulgaricus ameliorate symptoms and modulate the immune response in a mouse model of dextran sulfate sodium-induced colitis

“…Feeding mice a YC mixture promoted members of epitheliumassociated Firmicutes (lactobacilli, bifidobacteria, and enterococci, to varying degrees) but also enterobacteria and yeasts. All of these microbes possess high binding affinity for epithelial cell membranes (Boudeau et al, 2003;Swidsinski et al, 2008;Wasilewska et al, 2010;Christoffersen et al, 2012;Sengupta et al, 2013;Richardson et al, 2018). Enterococci increased in both DSS groups; however, enterobacteria and yeasts increased only in the mice administered YC mixture.…”

Effect of Low-Immunogenic Yogurt Drinks and Probiotic Bacteria on Immunoreactivity of Cow’s Milk Proteins and Tolerance Induction—In Vitro and In Vivo Studies

“…lactis Bi30, B. lactis J38, Lactobacillus plantarum W42, and L. plantarum IB. The strains originated from the collection of the IAR&FR PAS (Olsztyn, Poland) and were characterized previously [13,[25][26][27]. S. thermophilus and L. bulgaricus strains were matched in pairs to form starter cultures displaying synergistic effects during the manufacture of yogurts, as follows: S. thermophilus TKM3 and L. bulgaricus DB3 (set TKM3 + DB3), S. thermophilus MK10 and L. bulgaricus 151 (MK10 + 151), and S. thermophilus 2K and L. bulgaricus BK (2K + BK) [28][29][30].…”
