Abstract
The aim of this study was to assess the effects of dietary complex probiotic (Lactobacillus acidophilus, 1.0횞107 CFU/g; Saccharomyces cerevisae, 4.3횞106 CFU/g; Bacillus subtilis 2.0횞106 CFU/g) on growth performance, nutrients digestibility, blood characteristics and fecal noxious gas content in growing pigs. Ninety [(Duroc횞Yorkshire)횞Landrace] pigs with the average 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 include: 1) CON (basal diet); 2) CP1 (basal diet+complex probiotic 0.1%) and 3) CP2 (basal diet+ complex probiotic 0.2%). During the entire experimental period of 6 weeks, results showed that addition of complex probiotic at the level of 0.2% to diet increased ADG significantly (p<0.05). Also, digestibilities 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) by complex probiotic supplementation. 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.
