lactating crop 2
the underlying mechanisms responsible for the formation of pigeon milk remain to be fully elucidated. In this study, crop sacs were collected from 225-day-old unpaired, non-lactating male Zhongshan Shiqi pigeons (MN), as well as from males that commenced lactation on the first day post-incubation (ML). Subsequently, we performed RNA sequencing (RNA-seq), ribosome profiling, and single-cell transcriptome sequencing (scRNA-seq).
