摘要: Biomarkers are useful tools in research and clinical practice where they often used to detect monitor differences the physiological state of an animal. The proteins IGF-1, IGFBP-3, GHR, CRP, SAA, Hp, IFN-α, IFN-γ, TNF-α, IL-1β, IL-6, IL-10, IL-18 have been proposed as potential biomarkers for monitoring growth livestock. objective this study was determine whether hepatic gene expression these is associated with performance nursery pigs. Herd information parameters were collected 168 piglets from 8 commercial farms southern Ontario. From pigs, a subset liver tissue samples (n = 74) analysis biomarkers. Multivariable linear regression methods genetic nursery. Modelling herd individual piglet traits relation revealed that weight at weaning age significantly performance. Average daily gain (ADG) IGFBP-3 GHR (P < 0.05), tended be IGF-1 (P = 0.071). Similarly, 9-week body (P = 0.055). which pigs weaned important determinant Hepatic can
