Abstract

In order to study the effects of supplementary $Safmannan^(R)$(Beta-glucan & MOS complex) and $World-Labs^(R)$ (multiple probiotics) on the performance, nutrient availability, small intestinal microflora and immune response in broiler chicks, one thousand hatched broilers ($Ross^(R)$ were assigned to 4 treatments: control(basal diet), $BMD^(R),\;Safmannan^(R)\;and\;World-Labs^(R)$. There were no significant differences in the performance and in serum IgG, ND titre. However parameters of leukocytes and erythrocytes were significantly different among treatments (p<0.05). Leukocytes and RBC of $World-Labs^(R)\;and\;Safmannan^(R)$ were mostly lower than $BMD^(R)$ and control whereby MCH and MCHC of $World-Labs^(R)\;and\;Safmannan^(R)$ were higher than other treatments. The cfu of intestinal microflora had no significant differences among treatments. The $BMD^(R)$ treatment was higher than others in amino acid and crude fat availability and $World-Labs^(R)$ was higher than others in crude fiber availability. It was concluded that supplements used in the present experiment did not significantly affect the production parameters. However, significant impact on blood parameters, especially on leucocytes, may need further investigation.

본 실험은 Beta-glucan과 MOS의 복합제 $Safmannan^(R)$과 복 합생균제 $World-Labs^(R)$가 육계의 생산성과 영양소 이용율, 소장내 미생물 균총 및 면역 체계에 미치는 영향을 측정하기 위해 대조구에 $BMD^(R)$ 처리구, $Safmannan^(R)}$ 처리구 그리고 $World-Labs^(R)$ 처리구 등 4 처리구로 두었다. 실험의 결과를 종합해 보면 생산성에 있어서는 처리에 따른 유의한 차이는 나타나지 않았으나, 그 동안에 밝혀진 선행 실험들의 결과와 유사한 경향을 나타내었다. 즉, 생산지수에서 $BMD^(R)$ 처리구 가장 높고 다음으로 $Safmannan^(R)$ 처리구와 $World-Labs^(R)$ 처리구였으며 대조구가 가장 낮았다. IgG, ND titer 그리고 장내 균총들은 처리간에 유의한 차이를 나타내지 않았다. 그러나 백혈구 및 적혈구 계통의 혈액 분석 결과는 매우 유의한 차이를 나타내었는데, $World-Labs^(R)$ 처리구와 $Safmannan^(R)$ 처리구들은 $BMD^(R)$처리구와 대조구에 비해 leukocytes와 RBC 가 전반적으로 적었으며, 평균 적혈구 혈색소량(MCH)과 혈색소 농도(MCHC)는 높았다. 이렇게 뚜렷한 혈액 성분 분석치의 차이에 대한 임상 및 생리학적 의의는 앞으로 규명해야 할 과제이다. 장내 미생물의 결과는 통계적 유의차는 없었으나 괴사성 장염을 유발하는 Cl. perfringens가 $World-Labs^(R)$ 처리구에서는 검출되지 않았으며 영양소 이용율에서는 일부 아미노산과 조지방의 경우 $BMD^(R)$ 처리구가 가장 높았으며 조섬유의 경우 $World-Labs^(R)$ 처리구가 가장 높았다.
