Demonstrates increased growth in neonatal lambs following maternal supplementation with arginine, suggesting improved health outcomes.
RP-Arg specifically elevates colostrum IGF-1 and lactoferrin levels, enriches ileal Bacteroidota and Prevotella, and reprograms hepatic arginine-proline and ABC transporter metabolism. Overall, these changes were associated with an increased early growth rate of lambs without affecting milk protein production.
