The potential role of palygorskite and probiotics complex on the laying performance and faecal microbial community in Xuefeng black-bone chicken

The impact of dietary supplementation of polysaccharide derived from Polygonatum sibiricum on growth, antioxidant capacity, meat quality, digestive physiology, and gut microbiota in broiler chickens

“…Furthermore, Li et al (2022a) found that the relative abundance of Alistipes in cecal contents might elevate intestinal mucosal factors such as mucin 2 while decreasing inflammatory cytokine concentrations, Bax gene expression, and the Bax/Bcl-2 ratio in the intestinal mucosa. Additionally, Deng et al (2022) found that the relative abundance of CHKCI001 in fresh greenish-yellow faeces from Xuefeng black-bone chickens had benefits in improving laying performance and feed conversion ratio. On the other hand, increasing the abundance of Methanobrevibacter has been linked to improving energy capture and fat accumulation.…”

Investigating the impact of pigmentation variation of breast muscle on growth traits, melanin deposition, and gene expression in Xuefeng black-bone chickens

“…Over an extended period of domestication, it has developed stable genetic traits and unique flavor. These traits encompass notable black features in the skin, bones, meat, beak, legs, cockscomb, and tongue ( Deng et al, 2021 ; Deng et al, 2022 ). However, a noteworthy phenomenon was observed during the slaughter process, revealing significant variations in the blackness of breast muscles ( BBM ) among Xuefeng black-bone chickens.…”
