Abstract

The research was conducted to study the feeding value of crude soylecithin produced as by-products of soybean oil manufacturing in broiler ration. The results obtained were as follows. 1. The chemical composition, mineral composition, Vitamine contents and gross energy values of crude soy-lecithin were determined 2. No significant difference was observed for the body weight gain of broiler between control and lecithin groups of 3%, 6%, 9o/e and 12% addition. 3. Significant difference (P<0.05) was observed for feed intake lecithin 12% composed with lecithin 6% and 9% group, However, no significant difference was found among control, lecithin 3%, 6%, and 9% groups. 4. No significant difference was found for feed conversion between treatments. However, the lowest figure 2.32 for lecithin 9% treatments, followed by 2.40 of lecithin 6% and 2.41 of lecithin 3% orderly. 5. The composition of moisture, crude protein and ether extract in broiler carcas ranged from 71.2 to 72.15%, from 15.93 to 16.45% and from 6.19 to 7.05% respectively. 6. The weight of abdominal fat and live fat in broiler caress ranged from 42.4 to 63.7 gm, and from 2.2 to 2.4gm respectively. difference between abdominal and live fat weight was showing in significant statistically. 7. The present data reveal that soy-lecithin as by-product of soybean oil manufacturing was valuable energy source.

Broiler에 있어서 대두유의 처리공정중에서 부산물로 생산되는 Lecithin의 사료적가치에 관한 연구결과를 요약하면 다음과 같다. 1. Lecithin의 일반성분 무기성분 비타민 그리고 총에너지를 측정하였다. 2. Lecithin을 Broiler 후기사료에 3%, 6%, 9%, 12%까지 첨가하여도 병아리의 증체량에는 대조구와 유의차가 없었다. 3. 사료섭취량에 있어서는 대조구 Lecithin 3%, 6%, 9%의 처리간에는 유의차가 없었으나 12%구는 6%, 9%구에 비해 유의적으로 많았다. (P<0.05) 4. 사료요구율에 있어서도 각 처리구간 유의차가 없었으나 Lecithin 9%구가 2.32로서 요구율이 가장 낮았고 그 다음이 Lecithin 6%구의 2.40,3%구의 2.41의 순이었다. 5. 도체성적에 있어서 도체의 수분함량은 71.2-72.5%로서 처리간 유의차가 없었고 조단백질 함량은 15.93-16.45, 조지방의 함량은 6.19-7.05%였다. 6. 복지방함량은 42.4-63.7g으로 Lecithin 첨가구가 약간 낮은 경향을 나타냈으며 간중량도 처리간 유의차가 없었다. 간지방중량은 2.2-2.4g정도로서 처리간 유의차는 없었으나 Lecithin 첨가구가 약간 낮은 경향을 나타내었다. 7. 이상의 시험결과 대두유 부산물인 Lecithin은 Energy 사료로서 우수하였다.
