초록
본 연구는 항생제를 대체할 목적으로 동물체의 활성을 가져오는 원료로 알려져 있는 활성탄과 목초액, sodium bentonite, 홍삼박, 생균제를 선별하여 이들 원료로 구성된 항생물질 대체제를 개발하여 홀스타인 수송아지에 급여하였을 때 생산성에 미치는 효과를 규명하고자 수행하였다. 송아지의 일당증체량은 대조구(1.01kg), 처리구(1.01kg)간에 유의적인 차이가 없었고(P>0.05), 사료 요구율은 대조구 3.24에 비하여 처리구 2.80로 처리구에서 유의적인 개선효과를 나타냈다(P<0.05). 설사 발생률은 동일하였으나 분 상태는 처리구가 양호하였고, 호흡기 질병은 처리구에서는 발생하지 않았다. 분 중
This study was carried out to develope an antibiotic substitute with some feed additive ingredients; activated charcoal, microbial products(Saccharomyces cerevisiae), sodium bentonite and pyroligneous. Sixty Holstein male calves(control 30 and tested 30 calves) were assigned to one of two diets, control(containing commercial antibiotic) and treatment diet (containing antibiotic substitute) with three replicates(10 calves each). The experiment were carried out for 30 days. The daily weight gains were similar between control(1.01kg/d) and treatment groups(1.01kg/d), however feed requirement were lower for treatment calves (2.80kg) than control calves (3.24kg) (P<0.05). Also calves were more health for treatment calves than control calves for diarrhea and respiratory diseases occurrences. The ammonia concentration of feces were lower for treatment calves(2.67 ppm) than for control calves(6.33 ppm) (P<0.05). No statistical difference were found in blood substances between control and treatment calves(P>0.05). In conclusion, the calve performances were improved by substitute without commercial antibiotic additive.
