One hundred and eighty crossbred weaned pigs [(Yorkshire-Landrace) x Duroc; 28 d old; ± kg of BW] were randomly allotted to 2 treatments in a randomized complete block design. The 2 experimental treatments included (1) basal diet with inorganic trace minerals (Control) and (2) As 1 + Availa-Starter 123. Pigs were blocked by their initial body weight. Sex and ancestry were equally distributed across treatments. There were 15 pigs/pen and 6 replicate pens/treatment. The ADG of pigs fed the Availa-Starter 123-supplemented diet ( g) was greater than (P = ) that of pigs fed the control diet ( g) during the experimental period. The Availa-Starter 123 increased (P = ) the final BW of pigs ( kg/pig) when compared with the control ( kg/pig). The diet supplemented with Availa-Starter 123 did not affect ADFI and F:G of pigs as compared with the control (P > ). No differences in the mortality, incidence of diarrhea, and number of antibiotic treatments between the two treatments were found (P > ). Briefly, addition of AvailaStarter 123 to a commercial nursery diet containing inorganic trace minerals improved the growth performance of pigs as it increased the ADG and final BW of pigs.
