Abstract
Antler of deer have been used in Asia as a dietary supplementary or alternative medical substance. The antler contains various biological active substances, including ganglioside has been known to promote growth, bone hyperactivity, immune function, protein synthesis and various pharmacological action. Therefore, this study was to investigate the effect of antler on productivity of broiler chicks. Feeding trial has a number of 240 broiler chicks was conducted to investigate the effect of antler extract (AE) treated feeds on body performance, breast meat composition and characteristics in broilers. Each treatment had 15 chicks with 4 replications. The supplementation level of AE treated feeds was 0.3, 0.6 and 0.9% in the experimental diets. The results obtained were summarized as follows: Average body weight gain was significantly (p<0.05) increased in broilers fed with AE compared to that of control during overall periods. Especially, the body weight gain of 0.9% AE treated chickens showed highly increased by 6.0% compare to the control. Average feed intake was not significantly different among the treatments. Average feed efficiency was significantly (p<0.05) improved by 4% in broiler chicks fed with AE compare to that of control. Average breast meat composition and concentration of cholesterol were also not different by feeding the AE. In breast meat characteristics, the shear force (kg/0.5inch2) of breast meat showed similar results in all treatments. The cooking loss of breast meat was significantly lower in the chick fed AE than that of control. But the water holding capacity (%) of breast meat was significantly (p<0.05) higher in the chicks fed AE than that of control. In breast meat color of chicks were not significantly different in all treatments. The thiobarbituric acid reactive substances (TBARS) and volatile base nitrogen (VBN) value were not showed different with all treatments. Also, the fatty acids composition of breast meat were showed similar results in all treatments. In conclusion, the dietary feed of AE tended to improve the body weight gain and feed efficiency, but did not influenced breast meat characteristics of broiler chicks
사료 내 녹용추출물의 첨가가 육계의 증체, 도체 조성 및 품질에 미치는 영향
초록
녹용은 오랫동안 동양에서는 주요 한방제로 사용된 사 슴의 뿔로서 ganglioside를 비롯한 다양한 생리활성물질을 함유하고 있어 면역기능, 골대사항진, 발육촉진, 단백질 합 성 촉진작용 등의 약리작용이 있는 것으로 알려져 왔다. 따라서 본 시험은 녹용에 함유된 다양한 생리활성물질이 가축의 생산성과 도체성분에 미치는 영향을 파악하기 위 하여 녹용추출물을 육계 사료에 각각 0.3, 0.6 및 0.9% 수 준으로 첨가 급여하여 육계의 증체량, 사료섭취량, 사료효 율 및 도체특성에 미치는 영향을 분석하고자 사양시험을 실시하였으며, 본 시험에서 얻어진 결과를 요약하면 다음 과 같다. 전 사양시험 기간에서 증체량은 녹용추출물 첨가 에 의한 유의적인(p<0.05) 차이가 나타났으며, 녹용추출물 0.9% 첨가구인 D구가 가장 높은 증체 성적을 보였다. 사료 섭취량은 녹용추출물 첨가에 의한 유의적인 차이가 나타 나지 않았다. 사료요구율은 대조구에 비하여 녹용추출물 0.6% 및 0.9% 처리구가 약 4% 향상된 결과를 보였다 (p<0.05). 도체특성에서 도체의 일반성분 및 콜레스테롤 함 량은 녹용추출물 첨가에 의한 차이가 나타나지 않았다. 도 체의 전단력은 대조구에 비하여 녹용추출물 첨가구가 낮 은 값을 보였고, 보수력은 녹용추출물 첨가구가 유의적으 로(p<0.05) 높고, 가열감량은 유의적으로 (p<0.05) 낮게 나 타났다. 육색은 녹용추출물 첨가구에 의한 처리구간의 유 의적인 차이는 나타나지 않았다. TBARS 및 VBN도 녹용 추출물 첨가에 의한 차이가 나타나지 않았다. 또한 육계 가슴살의 지방산 조성도 녹용추출물 첨가에 의한 차이가 나타나지 않았다. 결론적으로 녹용추출물을 첨가함으로서 육계의 증체량 및 사료효율을 향상시키데 효과가 있는 것 으로 나타났다.
