Effects of coated sodium butyrate on performance, egg quality, nutrient digestibility, and intestinal health of laying hens

Dietary sodium butyrate improves female broiler breeder performance and offspring immune function by enhancing maternal intestinal barrier and microbiota

“…Supplementary SB can improve the performance of broilers by improving intestinal development ( Liu et al, 2017 ). Dietary butyrate has a regulatory effect on the transport of mineral elements ( Gommers et al, 2022 ), while SB improves egg production and shell strength and reduces feed conversion ( Wang et al, 2021b ; Zhang et al, 2022b ). Feeding SB for 5 wk improved the immunity and growth potential of 40-wk-old laying hens’ offspring ( Gong et al, 2020 ).…”

“…Dietary SB results in improved performance by promoting gastrointestinal development in poultry and has a dose-related effect ( Lan et al, 2020 ). In laying hens, SB influences nutrient digestibility, thereby affecting production performance ( Zhang et al, 2022a ), as well as amino acid metabolism and intestinal immune function induced by cecal microorganisms ( Zhong et al, 2022 ). In the modern broiler industry, where rapid growth rate is often associated with increased stress and immune challenges, SB can modulate the intestinal permeability of broilers and regulate the intestinal microbial community ( Naghizadeh et al, 2022 ), thereby improving immune function and stress resistance ( Bortoluzzi et al, 2017 ).…”

Rosemary extract improves egg quality by altering gut barrier function, intestinal microbiota, and oviductal gene expressions in late-phase laying hens

“…Moreover, intestinal microbiota can regulate fatty acid composition of yolk in Japanese quail, including increasing C18:0 and decreasing C14:1 and C16:1 [37]. It is worth noting that the addition of sodium butyrate to diets enhanced production performance and egg quality of laying hens such as yolk color and egg shell strength [38,39]. In this study, spearman correlation between SCFA and egg quality indicated that butyrate signi cantly increased Haugh unit and decreased the accumulation of C15:0 and n-6/n-3 in egg yolk.…”

Dietary supplementation with Clostridium butyricum and its ferment substance improves the egg quality and ovarian function in laying hens from 50 to 58 weeks of age

“…The decrease in egg quality of laying hens as extending the egg production period has been noticed in practice (Tumová & Gous, 2012), which is closely linked to sustainedly damaged intestinal barriers and reproductive organs because of age and the high intensity of production (Braw‐Tal et al, 2004; Gu et al, 2021; Wang et al, 2020). To mitigate these adverse effects, some strategies, including organic acids butyrate (Abbasi Arabshahi et al, 2021; Kazempour & Jahanian, 2017; Zhang, Zhang, et al, 2022), vitamins (Gan et al, 2020), probiotics such as Clostridium butyricum ( C. butyricum ) (Wang et al, 2021), and essential oils (Wang et al, 2022; Zhang, Wang, et al, 2022), have been widely sought out in the laying chicken industry. Of note, C. butyricum , a butyrate‐producing bacteria, has been used as a probiotic in clinical and veterinary medicine for decades (Ariyoshi et al, 2022).…”
