A total of two hundred twenty-five crossbred piglets LW-Pietrain x LD-LW (barrows and gilts) with an initial BW of 8.20 ± 1.60 kg (28 ± 2 days of age), were used to investigate the effect of two additives on the productive performance. There were three dietary treatments with the same energetic and protein levels, in a complete randomized block design (two blocks of 8 and 7 pens, 15 piglets/pen): A, control; B, control with 0.1% probiotic Pediococcus acidilactici (109 CFU/kg feed); C, control with a derived of prebiotic Saccharomyces cerevisiae (0.1% in feedstuff). No differences were observed by inclusion probiotic (B) or prebiotic (C) in the first test period (28-39 days of age). However, in the second phase (39 to 60 days of age), the addition of prebiotic and probiotic significantly improved ADG (354 vs 298, 297 g/d. C, B, A, respectively; P < 0.05 ) and FC (1.96 vs 2.09 vs 2.23 g/d C, B, A, respectively; P<0.05), with the same ADFI (P > 0.05). In overall experimental period (28-60 days of age) use of prebiotics improved ADG (353 vs 319, 310 g/d C, B, A; P<0.05), and the use of both additives significantly improved FC (P < 0.05). We conclude that it should further investigate the patterns of use of probiotics and prebiotics to optimize their use in commercial production conditions.
