Growth performance
Effects of Cr-CNP on growth performance are shown in Table 2. The G:F of pigs fed supplemental 100, 200, 400 μg/kg of Cr from Cr-CNP was increased (3.47, 3.73, and 3.47%, respectively; P o 0.05) compared with those fed the control diet, which resulted in both linear and quadratic increases in G:F as Cr-CNP supplementation increased (P o 0.05). The ADG and ADFI were not affected by dietary treatments.
