초록

본 시험은 육계 사료 내 발효 마늘 및 양파 부산물을 첨가 급여하였을 때 생산성, 혈액 성상 및 장내 미생물에 미치는 영향을 알아보고자 시험을 실시하였다. 육계(Ross) 초생추총 480수를 공시하여 4처리 4반복, 반복 당 30수씩 공시하여 5주간 시험을 실시하였다. 처리구로는 항생제를 첨가하지 않은 처리구(NC, negative control), 항생제 처리구(PC, positive control), 발효 양파 부산물 1.0% 첨가구 (T1), 그리고 발효 마늘 부산물 1.0% 첨가구 (T2)로 나누어 실험을 실시하였다. 종료 체중은 발효 마늘 부산물 첨가구에서 1,752 g으로 다른 처리구와 비교 시 가장 높게 나타났으며(P<0.05), 무항생제 처리구에서 1,606 g으로 가장 낮았다. 증체량에서 역시 발효 마늘 부산물 처리구에서 무항생제 처리구 및 항생제 처리구보다 각각 9%와 5% 이상 높게 나타났다(P<0.05). 발효양파 발효물 첨가구에서는 무항생제 처리구와 비교 시 유의적으로 높게 나타났으나, 항생제 첨가구와 비교하였을 때는 처리 간 유의성이 인정되지 않았다. 5주간 사양 실험 후 혈구 분석 및 혈액 생화학 분석 결과, 무항생제 처리구를 비롯한 모든 처리구에서 유의적인 차이는 없었다. 육계 맹장 내유산균 수는 발효 마늘 부산물 첨가구에서 다른 처리구와 비교 시 가장 높았으며(P<0.05), 발효 양파 부산물, 항생제 첨가구에서는, 그리고 무항생제 처리구에서는 통계적 차이가 나타나지 않았다. 또한 대장균수와 살모넬라에서는 무항생제 처리구와 비교 시 항생제 처리구와 발효 마늘 및 양파 부산물 첨가구에서 낮은 경향을 나타냈으나 통계적인 차이는 없었다. 결과적으로 육계 사료 내 발효 양파 및 마늘 부산물의 첨가 급여는 장내 균총에 효과적이며, 결과적으로 생산성을 개선시키는 것으로 나타났다. 하지만 현재까지 발효 농산 부산물에 대한 연구가 부족하다는 점을 감안할 때 향후 더 많은 연구가 필요할 것으로 사료된다.

This study investigated the effects of dietary supplementation of the fermented by products garlic and onion on growth performance, blood composition and cecal microflora in broiler chickens. A total four hundred eighty, day old broiler chickens (Ross) were randomly divided into four groups with four replicates of thirty birds each. The treatment groups were negative group (NC, antibiotic-free diet), positive group (PC, basal diet with 0.05% and 0.03% anticoccidials), fermented of onion by product 1.0% group (T1) and fermented of onion by product 1.0% group (T2). The body weight of broilers fed the diets containing fermented by products garlic was higher than the other treatments during overall period. No significant difference were observed on serum chemical composition and blood corpuscle. In the cecal microflira of broiler, the population of the Lactic acid bacteria was showed the higher in chicken fed diets supplemented with fermented of garlic group than other groups (P<0.05). These results suggest the possibility that fermented of garlic and onion by product could be used as the alternative of antibiotics growth promotor of broiler chickens.
