Effects of combination of mannan-oligosaccharides and β-glucan on growth performance, intestinal morphology, and immune gene expression in broiler chickens

Effects of feeding a thermomechanical, enzyme-facilitated, coprocessed yeast and soybean meal on growth performance, organ weights, leg health, and gut development of broiler chickens

“…Independently of the age, feeding pYSM did not significantly influence the gut morphology of the broiler chickens, thus suggesting no pYSM-related negative effects on intestinal development, health, and functionality, and reasonably explaining the unaffected small intestine weights. These results are in contrast with the available literature, as previous studies reported that β-glucans contained in yeast can improve gut morphology ( Teng et al, 2021 ). In particular, Morales-López et al (2009) , Ding et al (2019) , and Teng et al (2021) found greater Vh and Cd in duodenum and jejunum/ileum after the administration of yeast β-glucans.…”

Moreover, Cox et al (2010) reported ameliorated Vh and Cd after β-glucans administration in Eimeria - or coccidian-challenged broiler chickens.…”

Effects of nonantibiotic growth promoter combinations on growth performance, nutrient utilization, digestive enzymes, intestinal morphology, and cecal microflora of broilers

“…Increasing villus height provides an increased surface area for the absorption of available nutrients [ 55 ]. The villus crypt is considered the villus factory, and deeper crypts indicate rapid tissue turnover to permit villus renewal as needed in response to normal sloughing or inflammation from pathogens or their toxins and high tissue demands [ 56 , 57 ]. Intestinal epithelial cells originating in the crypt migrate along the villus surface upward to the villus tip and are extruded into the intestinal lumen within 48 to 96 h [ 58 , 59 ].…”

Effects of nonantibiotic alternative growth promoter combinations on nutrient utilization, digestive enzyme activity, intestinal morphology, and cecal microflora of broilers

“…Increasing villus height provides an increased surface area for the absorption of available nutrients [39]. The villus crypt is considered the villus factory, and deeper crypts indicate rapid tissue turnover to permit villus renewal as needed in response to normal sloughing or inflammation from pathogens or their toxins and high tissue demands [40, 41]. Intestinal epithelial cells originating in the crypt migrate along the villus surface upward to the villus tip and are extruded into the intestinal lumen within 48 to 96 h [42, 43].…”
