- Abstract
The aim of this study was to assess the effects of dietary complex probiotic (Lactobacillus acidophilus, 1.0×107 CFU/g; Saccharomyces cerevisae, 4.3×106 CFU/g; Bacillus subtilis 2.0×106 CFU/g) on growth performance, nutrient digestibility, blood characteristics and fecal noxious gas content in growing pigs. A total of 90 [(Duroc×Yorkshire)× Landrace] pigs (initial BW of 39.75±1.97 kg) were allocated into three treatments by a randomized complete block design. There were five pens per treatment with six pigs per pen. Dietary treatments were: 1) CON (control diet); 2) CP1 (CON + complex probiotic 0.1%) and 3) CP2 (CON + complex probiotic 0.2%). During the entire experimental period of 6 wk, results showed that addition of complex probiotic at the level of 0.2% to diet increased ADG (623 vs. 576g) significantly. Digestibility of DM and N tended to increase, however, no significant differences were observed (P>0.05). Blood characteristics (IgG, albumin, total protein, RBC, WBC and lymphocyte) of pigs were not affected (P>0.05) in two complex probiotic supplementation treatments. Fecal NH3-N was decreased (11.8%) significantly by the addition of complex probiotic (P<0.05), but no effects were observed on fecal acetic acid, propionic acid and butyric acid concentrations (P>0.05). In conclusion, results in this experiment indicated that dietary complex probiotic supplementation had a positive effect on growing pigs performance and could decrease fecal NH3-N concentration.
