Impact of chitosan on productive and physiological performance and gut health of poultry

Evaluation of commercial doses of a feed additive and silymarin on broiler performance with and without CCl4-induced liver damage

“…Besides CCl 4 exposure, we also examined the influence of CA-PFA and silymarin on productive performance and protective effects against liver damage. Silymarin has been extensively used to treat or prevent hepatic damage ( Saeed et al, 2017 ; Baradaran et al, 2019 ; Armanini et al, 2021 ; Guerrini and Tedesco, 2023 ), and several studies have explored its benefits for human and veterinary use ( Surai and Surai, 2023 ; Elnesr et al, 2023 ). However, specifically in the poultry industry, which demands practical and cost-effective solutions, the dose is a critical aspect to be analyzed when determining the efficacy of feed additives ( Surai and Surai, 2023 ).…”

“…Silymarin, betaine, and turmeric extracts have been extensively studied because of their benefits, which have been summarized in many reviews ( Yarru et al, 2009 ; Akhavan-Salamat and Ghasemi, 2016 ; Zaker-Esteghamati et al, 2020 ; Nawab et al, 2020 ; Mishra et al, 2021 ; Abd El-Hack et al, 2021 ; Abd El-Ghany and Babazadeh, 2022 ; Alagawany et al, 2022 ; Ugo et al, 2022 ; Elnesr et al, 2023 ; Gana et al, 2023 ; Guerrini and Tedesco, 2023 ; Surai and Surai, 2023 ; Sureshbabu et al, 2023 ). Adding these active ingredients to livestock and poultry feed improves metabolism, reproduction, immunity, nutrient digestibility, fat metabolism and can alleviate chronic liver injuries and mitigate the detrimental effects of heat stress, improving overall health and favoring animal growth and development.…”

High molecular/low acetylated chitosans reduce adhesion of Campylobacter jejuni to host cells by blocking JlpA

“…for poultry farming, could contribute to reduced infection rates of the animals (Fernandez et al 2000 ; Lengsfeld et al 2007 ). Chitosan might be a suitable polymer to be considered in poultry farming due to biodegradability, antimicrobial, nontoxicity, and low costs of the raw material (Elnesr et al 2022 ). On the other side, chitosans are a quite divers group of glucosamine polymers differing in molecular weight and degree of acetylation but also in the respective pattern of acetylation which characterizes the distinct fine structure of the polysaccharides.…”

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

“…COS was the degradation product of chitin, which was the second abundant polymer after cellulose in nature ( Hahn et al, 2020 ). In recent decades, COS was widely used to promote growth performance in broilers due to its unique biological activities, such as antimicrobial, antioxidant, anti-inflammation and immune regulation functions ( Elnesr et al, 2022 ; Uyanga et al, 2023 ). Numerous studies were conducted to evaluate the functionality of COS in improving poultry intestinal health and production.…”
