Abstract

Antibiotics in veterinary medicine have been used to treat disease, promote growth rate and improve feed efficiency. However, alternative sources are needed because of of bacterial resistance to antibiotics and residues of antibiotics. The present study was carried out to evaluate the effect of CS682, a fermentation product of Korean soil bacteria, on safety, growth rate and feed efficiency, and to evaluate its value as an alternative for antibiotics used as a feed additive. Two dosages of CS682 (0.1% and 1%) were fed to chickens for 28 days. The results showed that, when compared to chickens in the control group, growth and feed efficiency was improved. Also, mortality, hematology, general clinical signs and necropsy were examined. Chickens in the treatment groups showed no adverse effects. A total of 72 weaning pigs were used to confirm the effects of CS682 at one dose level (0.1%) regarding feed efficiency. Supplementation with 0.1% CS682 also resulted in improved weight gain and feed efficiency ratio. Based on these results, CS682 may be effective in improving feed efficiency safely as a feed additive.
