The mannan of bakers' yeast (Saccharomyces cerevisiae) was fractionated on a column of diethylaminoethyl-Sephadex into five subfractions. Phosphate content of these mannan subfractions was proportional to the concentration of NaCl solutions used in the chromatographic separation. Quantitative precipitin reactions showed that the serological reactivities of the subfractions were proportional to ...

A study was conducted to evaluate the response of broilers to diets containing a mannan oligosaccharide, antibiotics, or a combination of antibiotics and mannan oligosaccharide. All diets were supplemented with copper sulfate to provide 250 mg/kg Cu in diets fed to 42 d and 62.5 mg/kg Cu in diets from 42 to 56 d, in addition to the 10 mg/kg provided in the trace mineral mix. Bio-Mos®, a mannan ...

effect of dietary prebiotic mannan oligosaccharide and β-1,3 glucan on growth performance, bodycomposition and immunity response of rainbow trout (oncorhynchus mykiss) were investigated for asix week culture period. four feeding strategies were set, including feeding prebiotic-free dietcontinuously (control), feeding dietary prebiotic continuously (t1), feeding dietary alternately (oneweek preb...

The human pathogen Candida albicans encodes at least three putative two-component histidine kinase signal transduction proteins, including Chk1p and a response regulator protein (Cssk1p). Strains deleted in CHK1 are avirulent in a murine model of hematogenously disseminated disease. The specific function of Chk1p has not been established, but hyphae of the chk1 mutant exhibit extensive floccula...

Currently, mannan-oligosaccharides (MOS) are added to the production costs of Nile tilapia prevent and avoid diseases. An alternative aquatic plants rich in biologically active compounds such as Lemna gibba, a freshwater macrophyte, Ulva lactuca, green seaweed, which have shown productive economic efficiency feed for livestock, poultry, fish, but their effect functional ingredient has not been ...

This study was conducted to evaluate the effects of Alphamune, a mixed prebiotic composed of mannan-oligosaccharide and β-glucans, on the growth performance, digestibility and enzyme activity of rainbow trout, Oncorhynchus mykiss. A basal diet was formulated using common feed ingredients supplemented with Alphamune at 0, 0.5, 1, 2, and 4 g.kg-1 leading to five experimental diets. Obtained resul...

A total of 150 weanling pigs [(Yorkshire × Landrace) × Duroc] with an average BW of 7.22 ± 0.80 kg (21 d of age) were used in a 28-d trial to determine the effects of dietary fructan and mannan oligosaccharides on growth performance, nutrient digestibility, blood profile, and diarrhea score in weanling pigs. Pigs were allotted randomly to 1 of 5 dietary treatments: 1) negative control (NC), bas...

Prebiotics are typically fibrous compounds that pass undigested through the upper part of the gastrointestinal tract and stimulate the growth or activity of advantageous bacteria that colonize the bowel and contribute to the well-being of their host (Gibson and Roberfroid, 1995). Some of the most widely used prebiotics in the poultry industry are fructo-oligosaccharides, mannan-oligosaccharides...

S OF PAPERS 195 M8 Pretreating primary macrophages (Mɸ) with Bacillus subtillus but not mannan oligosaccharide increases nitric oxide production after Salmonella enteritidis challenge. Marta Viguie*UG, Kimberly Livingston California Polytechnic State University, San Luis Obispo, CA Direct-fed microbials (DFM) including probiotic and prebiotic additives have been shown to improve growth and feed...
