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

¹BCS structured by scale of 1 = thin to 5 = over conditioned.

²CON = 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 = 10).

³ P-value associated with overall F-test for treatment.

⁴ P-values associated with specific contrasts.

⁵Change is calculated between days 54 and 152 of gestation.
