Effects of phosphatidylethanolamine on intramuscular fat deposition and key gene identification by transcriptome sequencing in broiler chickens.

ABSTRACT: High-intensity breeding of broilers has increased meat yield while reducing meat quality. Properly enhancing intramuscular fat (IMF) content is an effective strategy to improve chicken meat quality and boost consumer preference. Given that the role of phosphatidylethanolamine (PE) in chicken IMF metabolism remains unclear, we investigated the effects of PE on the meat quality, as well as the differentiation and gene expression regulation of chicken intramuscular adipocytes (IMAs). PE supplementation significantly increased the a* value of meat color and reduced shear force (P < 0.05); however, it did not exert a significant effect on the pH value 45 min post-slaughter (P > 0.05). After treating intramuscular adipocytes IMAs with 25, 50, and 100 µM PE, 100 µM PE supplement markedly enhanced
