유기태 셀레늄과 Vitamin E의 복합 급여가 육계의 생산성, 계육 품질 및 Selenium 축적에 미치는 영향 = Effects of Dietary Organic Selenium and Vitamin E on Growth Performance, Selenium Retention and Quality of Meat in Broiler Chickens

국문 초록 (Abstract)

비타민 E 150 IU, selenium yeast로 셀레늄 1.2 ppm에 비타민 E를 100, 150, 200 및 300 IU로 복합 첨가하였을 때 육계의 사료 섭취량, 증체량, 사료 요구율, 계육 품질 및 selenium 축적에 미치는 영향을 조사한 결과를 요약하면 다음과 같다. 1. $1{\sim}21$일의 증체량은 대조구와 비타민 E 150 IU 첨가구가 높았으며(P<0.05), 사료 섭취량은 비타민 E 150 IU 첨가구가 유기태 셀레늄 1.2 ppm에 비타민 E 150 IU와 200 IU를 복합 첨가한 구에 비하여 증가하였다(P<0.05). $21{\sim}35$일의 사료 섭취량은 대조구가 유기태 셀레늄 1.2 ppm에 비타민 E 200 IU를 복합 첨가한 구에 비하여 증가하였다(P<0.05). 그러나 시험 전기간의 사료 요구율은 대조구를 포함한 모든 처리구에서 차이가 없었다. 2. 가슴 근육의 셀레늄 함량은 대조구와 비타민 E 150 IU 첨가구에 비하여 유기태 셀레늄과 비타민 E를 복합 첨가함으로서 유의적으로 높게 나타났으며(P<0.05), 간조직의 셀레늄 함량 역시 대조구와 비타민 E 150 IU 첨가구에 비하여 유기태 셀레늄과 비타민 E를 복합 첨가함으로서 높게 나타났다(P<0.05). 3. 저장 기간별로 TBARS는 대조구와 비타민 E 150 IU 첨가구는 1일보다 3일차가 높게 나타났으나(P<0.05), 셀레늄 1.2 ppm에 비타민 E 100, 150, 200 및 300 IU 복합 첨가구는 1일과 3일간에서 차이가 없었으며, 3일차에는 대조구보다 비타민 E와 셀레늄 복합 첨가구가 낮게 나타났다(P<0.05). 이상의 결과를 종합하면, 육계 사료에 유기태 셀레늄 1.2 ppm에 비타민 E를 100, 150, 200 및 300 IU를 복합 첨가시 생산성에는 차이가 없으나 계육 내 selenium 함량과 저장성은 향상되었다.

The experiment was conducted to examine the effects of dietary organic selenium and vitamin E on weight gain, feed intake, feed conversion, and selenium retention in meat of broiler chickens. For each growth phase, the basal diet was supplemented with 0 (control), vitamin E 150 IU/kg and the combination of 1.2 ppm Se from selenium yeast (SY) and vitamin E 100, 150, 200 and 300 IU/kg. Weight gain was significantly higher in supplemental control and vitamin E 150 compared to the combination of 1.2 ppm SY and vitamin E 150 IU during day 1 to 21. Feed intake significantly(P<0.05) increased in supplemental vitamin E 150 compared to the combination of 1.2 ppm SY and vitamin E 150 and 200 IU during day 1 to 21. Feed intake was significantly(P<0.05) higher in control compared to that of combination of 1.2 ppm SY and vitamin E 200 IU during day 21 to 35. However feed conversion was not affected in supplemental vitamin E and SY during day 1 to 35. Selenium concentrations of breast muscle and liver tissue significantly increased (P<0.05) in supplemental combination of 1.2 ppm SY and vitamin E compared to the control and vitamin E 150 IU. TBARS of control and vitamin E 150 IU were significantly (P<0.05) higher in day 3 than day 1, but the combination of Se 1.2 ppm and vitamin E of TBARS had no difference during day 1 to 3. TBARS in day 3 was significantly (P<0.05) lower in supplemental combination of Se 1.2 ppm and vitamin E than control and vitamin E 150 IU.
