Restoring dietary protein level induces compensatory growth by modulating GH/IGF-1 axis of growth-limited piglets on a very-low-protein diet

Restoring dietary protein level induces compensatory growth by modulating GH/IGF-1 axis of growth-limited piglets on a very-low-protein dietThese samples were collected from the liver of piglets, the liver of CE-1, CE2 and CE-3 were collected 14 days after weaning, the liver of CL-1, CL2 and CL-3 were collected 28 days after weaning. Meanwihle, the piglets of C group (CE-1 ;CE-2; CE-3; CL-1;CL-2;CL-3) were fed the normal protein diet (NPD). However, the liver of TE-1, TE-2 and TE-3 were collected from piglets, which were fed the low protein diet (LPD). After 14 days, the diet was changed from LPD to NPD, the liver of TL-1, Tl-2 and TL-3 were collected at the same time as CL-1, CL-2 and CL-3
