초록

본 연구는 시력 보호에 효과가 있는 것으로 알려진 기능성 물질인 루테인을 산란계 사료 내 첨가 급여 하여 난황 내루테인 함량에 미치는 영향을 조사하였다. 그 결과, 산란계의 생산성에 있어서는 처리구간 유의적인 차이가 없었으나, 난황 색깔에 있어서는 루테인 2 ppm을 첨가 급여할 경우 난황색이 짙어지는 것으로 나타났다. 난황 내 루테인 함량에 있어서도 2 ppm을 첨가 급여할 경우 유의적인 차이가 있는 것으로 나타났다. 따라서, 이상의 결과를 종합해 볼 때 루테인 강화 계란 생산을 위해서는 산란계 사료 내 루테인 함유물질을 첨가 급여할 경우 원물보다는 추출물을 이용하는 것이 효과적인 것으로 나타났다.

This study was conducted to investigate the effect of dietary supplementation levels of spinach powder and extract on performance, egg quality and lutein content in egg yolk. Laying hens were subjected to one of the following treatments; C, basal diet (BD); T1, BD + 1 ppm lutein from spinach powder; T2, BD + 1 ppm lutein powder from spinach extract; T3, BD + 2 ppm lutein powder from spinach extract; T4, BD + 2 ppm lutein from spinach extract. As a result, performance of laying hens was no significant difference among treatments. T4 had a significantly (p<0.05) higher egg yolk color than the other treatments. As from the lutein content in egg yolk, T4 had a significantly (p<0.05) higher content than the other treatments. Finally, these results suggested that the dietary supplementation for lutein-rich egg production, lutein concentration must be higher than a minimum of 2 ppm. Also, dietary with lutein extract from raw materials was appropriate for lutein-rich egg production than dietary with raw materials.
