초록

본 실험은 성게 껍질 분말의 사료적 가치를 구명하기 위하여 첨가수준(0, 1, 3, $5\%$)에 따라 육계의 생산성, 계육의 무기물 및 혈중 콜레스테롤 등에 미치는 영향을 고찰하기 위하여 5주간 사양 시험하였다. 전기 3주간사료내 조단백질은 $21.5\%$, ME는 3,100 kcal/kg 수준으로 공급하였고, 후기에는 조단백질 $19\%$, ME 3,100 kcal/kg 수준으로 급여하였다. 처리구는 대조구(무첨가구) 성게 껍질 분말 $1\%$ 첨가구(T1), $3\%$첨가구(T2), $5\%$ 첨가구(T3)로 처리구당 4반복, 반복당 10수로 총 160수를 공시하였다. 그 결과 증체량은 T1구에서 사육전기에 현저하게 개선되었지만(P<0.05) 사육후기에는 가장 낮게 평가되었으며, 사료효율은 처리구 사이에 유의성이 인정되지 않았다(P>0.05). 총콜레스테롤은 대조구보다 성게 껍질 분말 처리구에서 낮게 나타났으며, HDL-C은 처리구 중T2, T3에서 높았고(P<0.05), LDL-C과 triglyceride는 유의성이 인정되지 않았다. 성게 껍질 분말 급여 수준에 따른 무기물의 변화는 대조구에 비해 처리구에서 Fe, Zn, Ca함량이 많았으며(P<0.05) 총무기물 함량은 성게 껍질 분말 급여구에서 많은 경향을 보여 주었다. 결론적으로 육계사료 내 성게 껍질 분말의 급여는 Ca, Fe 및 총무기물 함량이 증가된 계육을 생산할 수 있을 것으로 사료된다.

This experiment was conducted to compare the influences of dietary sea urchin shell powder (SUSP) supplemented to broiler diets on performance, mineral contents and blood cholesterol for 5 weeks. The experimental diets contained 21.5 and $19\%$ CP for the starting and finishing period, respectively The ME was 3,100 kcal/kg of feed in both starter and finisher diets. One hundred sixty chicks were assigned to 4 treatments with 4 replicates and fed one of 4 experimental diets containing different levels of SUSP: 1) Control (commercial feed) 2) T1 (commercial feed with $1\%$ SUSP) 3) T2(commercial feed with $3\%$ SUSP) 4) T3(commercial feed with $5\%$ SUSP). Body weight gain was higher in the T1 group when fed the starter diet (P<0.05), but was the lowest in T1 group for finishing period. Feed efficiency was not significantly different between the control and treatment groups (P>0.05). The total cholesterol of the control was higher than the treatment groups and the HDL-cholesterol were higher in T2 and T3. However, effects of diets containing graded levels of SUSP on LDL-cholesterol and triglyceride contents were not found (P>0.05). The SUSP diets were increased significantly the Fe, Zn and Ca contents of chicken meat, and tended to increase total mineral contents. In conclusion, dietary supplementation of SUSP to broiler diets could be applied to the enhancement of Ca, Fe and total mineral contents levels in chicken meat.
