^a,bMeans within a row with different superscripts differ (P ≤ 0.05).

¹CON = control, 100% NRC requirements (n = 11); RES = restricted, 60% CON nutrients (n = 11); RES-ARG = restricted + arginine, 60% CON nutrients with 180 mg rumen-protected arginine supplement per kg BW (n = 11).

² P-value associated with overall F-test for treatment.

³ P-values associated with specific contrasts.

⁴Change is calculated between birth and 54 d of age.
