Abstract |
This study was conducted to investigate the effects of feeding probiotics (gene modified yeast) on the growth performances in pigs. In pigs, this study investigated the effects of dietary probiotics which contained antibacterial probiotics (OR-7, bacteriocin, gene modified yeast) on growth performances and feed efficiency in pig farm. A total of 150 pigs were studied. The treatments are probiotics yeast (PY) 0.3% (basal diet + 0.3% plasmid modified probiotics), PY 0.5% (basal diet + 0.5% plasmid modified probiotics), yeast (Y) 0.3% (basal diet + 0.3% probiotics), Y 0.5% (basal diet + 0.5% probiotics) and control (basal diet). Weight gain, feed intake and feed efficiency were periodically recorded for 90 days. The treatment group trended higher weight gain, feed intake and feed efficiency than control. And, the PY group trended higher weight gain, feed intake and feed efficiency than Y group. |
