Abstract

This study compared the whey proteome of sow colostrum (SC) and goat colostrum (GC) using shotgun proteomics combined with protein equalization techniques (CPLL or ProteoMiner™) to enhance the detection of low-abundance proteins. Colostrum samples were pooled from 11 hand-milked sows (20 mL each, collected at 0 h postpartum), while GC samples (2 liters total) were collected from 50 goats during morning milking on day 1 postpartum. A total of 86 low-abundance proteins (
