Effects of varied molecular weight of chitosan oligosaccharides on growth performance, carcass trait, meat quality, and fat metabolism in indigenous yellow-feathered chickens

Chitosan Oligosaccharides Alleviate Heat-Stress-Induced Lipid Metabolism Disorders by Suppressing the Oxidative Stress and Inflammatory Response in the Liver of Broilers

“…Furthermore, COS supplementation could alleviate the increase in the absolute and relative weight of abdominal adipose in heat-stressed broilers, suggesting that COS supplementation alleviated heat-stress-induced excessive fatty acid synthesis and deposition. Consistent with our results, Li et al [ 58 ] and Wang et al [ 59 ] also demonstrated that COS supplementation reduced the relative weight of abdominal adipose.…”

The effects of supplemental dietary chitosan on broiler performance and myopathic features of white striping

“…The capacity for meat to hold water, ions, minerals like iron, and proteins is essential for palatability ( Ponsuksili et al, 2008 ). In indigenous yellow-feathered chickens, drip loss decreased when broilers were fed 0.6% chitosan for 8 wk ( Wang et al, 2022 ). Contrarily, no differences in drip loss were observed in the present study, which may be attributed to the supplementation of lower levels of chitosan.…”

Chitosan oligosaccharide improves intestinal function by promoting intestinal development, alleviating intestinal inflammatory response, and enhancing antioxidant capacity in broilers aged d 1 to 14

“…However, Li et al (2019) and Lan et al (2023) reported that dietary COS supplementation improved growth performance in broilers or yellow-feathered chicken aged d 1 to 21. These variable results probably due to the differences in COS molecular weight, deacetylation degree, polymerization, as well as the breed, age and health status of broilers ( Ayman et al, 2022 ; Wang et al, 2022 ).…”

“…Inconsistent with our results, former studies reported that dietary COS supplementation decreased MDA content in small intestine of broilers or laying hens ( Li et al, 2017 ; Li et al, 2019 ; Lan et al, 2020b ; Gu et al, 2022 ). These discrepancies might be attributed to the differences in COS molecular weight, deacetylation degree, polymerization, as well as the breed, age and health status of broilers ( Ayman et al, 2022 ; Wang et al, 2022 ).…”
