Research Progress on Pigeon Milk Components and Synthesis Regulation Mechanisms
Pigeons are altricial birds,and newly born squab cannot digest feed directly.Breeding pigeons(in-cluding female pigeons and male pigeons)take feed and produce pigeon milk to feed squab.Pigeon milk con-tains abundant nutrients such as protein,fat,minerals,and microbial communities.Its synthesis and secretion are influenced by the nutrient levels of pigeon feed and regulated by prolactin and insulin signaling pathways.In addition,the target of rapamycin complex 1(TORC1),Janus kinase 2(JAK2)-signal transducer and activa-tor of transcription 5(STAT5)signaling pathways,and microRNA(miRNA)related competing endogenous RNA(ceRNA)networks also play important roles in pigeon milk synthesis.This article mainly reviewed the nutritional composition and microbial community of pigeon milk,as well as the changes in hormones,signaling pathways,and crop histology during pigeon milk production,which intended to provide theoretical reference for improving the efficiency of the pigeon industry.[Chinese Journal of Animal Nutrition,2024,36(5):2743-2751]
