Milk quality in sows is affected by various factors, including the living environment. However, changes in protein-expression profiles in the milk of sows housed under different conditions are still unclear. Accordingly, in this study, we performed proteomics analysis of colostrum from sows housed under different conditions. Our results showed that housing conditions affected protein expression, and the effects of housing conditions were observed in both pregnancy and lactation. In comparison, the differentially expressed proteins were related to the immune system and metabolic processes, particularly fat metabolism. These results revealed the physiological changes in sows under different housing conditions. Overall, these findings provided important insights into the care and management of sows to enhance milk quality.
