Abstract

This work was carried out to investigate the effects of CDDGS (corn distillers dried grains with solubles) colors and phytase levels on the amino acid digestibility of broilers for 7 days. One hundred eight Ross broilers were used in 9 treatment groups with a $3\;{\times}\;3$ factorial design as three colors of DDGSs (DDGS1, DDGS2, and DDGS3) in combination with phytase (0, 500, and 1,000 FTU/kg). The $L^*$ values of DDGS1, DDGS2, and DDGS3 were 55.2, 39.8, and 28.3; the $a^*$ values, 8.8, 7.5, and 6.1; and the $b^*$ values, 41.3, 27.1, and 15.4, respectively. The ileal digestibility of amino acids was decreased as DDGS color was dark, and increased as additive phytase level was increased in the diet. Average digestibilities of essential amino acids were 67.6~80.0%, and those of nonessential amino acids 67.4~77.3. Amino acid digestibility was low in the dark DDGS with no phytase in the diet.

본 연구는 옥수수 DDGS의 색상과 phytase 첨가가 회장 아미노산 소화율에 미치는 영향을 조사하기 위하여 실시하였다. 공시 재료는 세가지 색상의 DDGS(DDGS1, DDGS2, DDGS3)를 이용하였으며, 시험계는 유사한 체중의 5주령 Ross종(Ross 308) 육계 수컷 108수(평균 체중 $1.8{\pm}0.2\;kg$)를 공시하였다. 시험 설계는 세 가지 색상의 DDGS와 phytase 첨가 3처리구(0, 500, 1,000 FTU/kg)의 $3{\times}3$ 복합 요인으로 총 9처리구, 처리당 12수씩 완전 임의 배치 하여 7일 동안 소화 시험을 실시하였다. DDGS의 색상은 각각 DDGS1이 $L^*=55.2$, $a^*=8.8$, $b^*=41.3$, DDGS2가 $L^*=39.8$, $a^*=7.5$, $b^*=27.1$, DDGS3이 $L^*=28.3$, $a^*=6.1$, $b^*=15.4$로 나타났다. DDGS의 색상에 따른 아미노산 소화율은 어두운 색이 밝은 색보다 모든 아미노산의 소화율이 낮게 나타났다. DDGS의 처리구에 phytase를 첨가하여 급여시에 소화율이 증가하는 경향이었다. 필수아미노산의 평균 소화율은 모든 처리구에서 각각 77.7, 80.0, 81.5, 76.0, 78.4, 80.1, 67.6, 69.6 및 71.0% 이었으며, 비필수 아미노산의 평균 소화율은 각각 73.6, 75.8, 77.3, 73.1, 75.3, 76.8, 67.4, 69.4 및70.7% 이었다. 이번 실험의 결과에서, DDGS 색상이 어두울수록 그리고 phytase 수준이 낮을수록 아미노산 이용률이 낮게 나타났다.
