Mechanistic investigation into the differences in growth performance and resistance to spring viremia of carp virus in common carp

In summary, our integrated multi-omics analysis suggests that enhanced nutrient absorption and xenobiotic processing may contribute to superior growth performance in the YB population, while elevated detoxification and antioxidant capacity may underlie stronger disease resistance in the CD population. These findings provide insights into the interplay between growth and immunity in carp and offer biomarkers for balanced breeding strategies.
