Abstract

Effect of microbial products made of Bacillus stearothermophilus DL-3 on growth of chickens and pigs was investigated. Two types of microbial product were made in this study. One is the microbial product made of culture broth of B. stearothemophilus DL-3 and rice bran which named as the microbial product A. The other is the microbial product made of culture broth of B. stearothermophilus DL-3, apple pomace, soybean pomace and rice bran which named as the microbial product B. Chickens were divided into three groups and each group was fed with $100\%$ general feed, $90\%$ general feed supplemented with $10\%$ microbial product A or $90\%$ general feed supplemented with $10\%$ microbial product B. The average chicken weight of each group was $41.1{\pm}2.5g,\;41.6{\pm}3.2g\;and\;42.3{\pm}2.9g$ and those after 28 days was $547.7{\pm}91.7g,\;560.1{\pm}17.2g\;and\;562.2{\pm}32.5g$, respectively. The average weight gain for each group was 506.6 g, 518.6 g and 519.9 g, respectively, and weight increases of groups fed with $90\%$ general feeder and $10\%$ microbial product A and B were $2.4\%\;and\;2.6\%$ higher than the group fed with $100\%$ general feed. Pigs were also divided into three groups and each group was fed like chickens. The average weight of each group was $9.3{\pm}1.0kg,\;9.4{\pm}1.1kg\;and\;9.6{\pm}1.0kg$ and those after 37 days was $19.3{\pm}4.1kg,\;20.2{\pm}3.9kg\;and\;20.8{\pm}4.2kg$, respectively. The average Weight gain for each group was 10.65 kg, 10.82 kg and 11.20 kg, respectively, and weight increases of groups fed with $90\%$ general feeder and $10\%$ microbial product A and B were $1.6\%$ and $5.2\%$ higher than the group fed with $100\%$ general feed.

유기물이 풍부한 토양에서 분리하여 동정한 Bucillus stearothermophilus DL-3균주의 배양액과 사과박, 간장박 및 미강 등을 사용하여 2종류의 미생물 제재를 제조하고 닭과 돼지의 생육에 미치는 영향을 조사하였다. 사과박의 주성분은 탄수화물이며 간장박의 주성분은 단백질이다. B. stearothermophilus DL-3 균주의 배양액과 미강을 사용하여 제조한 미생물 제제를 미생물 제제 A로 명명하고 B. stearothermophilus DL-3균주의 배양액, 사과박, 간장박 및 미강을 사용하여 제조한 미생물 제제를 미생물 제제 B로 명명하였다. 미생물 제재가 닭 및 돼지의 생육에 미치는 영향을 검토하기 위하여 일반사료를 급여한 구, 일반사료의 $10\%$를 미생물 제재 A로 대체하여 급여한 구 및 일반사료의 $10\%$를 미생물 제재 B로 대체하여 급여한 구로 나누어 효과 검정실험을 수행하였다. 실험에 사용한 각 구의 평균 병아리 무게는 각각 $41.1{\pm}2.5g,\;41.6{\pm}3.2g$$42.3{\pm}2.9g$이었다. 급여를 시작하지 28일 후, 각 구에 속한 병아리들의 평균 무게는 각각 $547.7{\pm}91.7g,\;560.1{\pm}17.2g$$562.2{\pm}32.5g$이었으며 각 구에 속한 병아리들의 평균 무게 증가는 각각 506.6 g, 518.5 g 및 519.9 g이었다. 즉, 일반사료의 $10\%$를 미생물 제재 A로 대체하여 급여한 군과 일반사료의 $10\%$를 미생물 제재 B로 대체하여 급여한 군은 일반사료를 급여한 군에 비하여 각각 $2.4\%$$2.6\%$의 무게 증가를 나타났다. 각 구의 평균 돼지 무게는 각각 $9.3{\pm}1.0kg,\;9.4{\pm}1.1kg$$9.6{\pm}1.0kg$이었다. 급여를 시작한지 35일 후, 각 구에 속한 돼지들의 평균 무게는 각각 $19.3{\pm}4.1kg,\;20.2{\pm}3.9kg$$20.8{\pm}4.2kg$이었으며 각 구에 속한 돼지들의 평균 무게 증가는 각각 10.7 kg, 10.8 kg 및 11.2 kg이었다. 닭의 사료 효과 검정 결과와 같이 일반사료의 $10\%$를 미생물 제재 A로 대체하여 급여한 군과 일반사료의 $10\%$를 미생물 제재 B로 대체하여 급여한 군은 일반사료를 급여한 군에 비하여 각각 $1.6\%$$5.2\%$의 무게 증가를 나타났다.
