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

DDGS의 색이 DDGS의 품질을 평가하는데 사용되는 이유가 무엇인가? | 국제표준컬러측정기구(CIE, Commission Internationale d'Eclairage)에서는 식품이나 사료의 색을 L*(0 어두움, 100 밝음), a*는 적색(고)-녹색(저) 및 b*는 황색(고)-청색(저)으로 표시하고 있다. 지금까지 사료 산업에서는 색도계를 사료의 아미노산 함량과 소화율을 추정하는데 이용하지 않았으나, DDGS 제품들의 색에 차이가 있고 밝기(L*) 및 황색(b*)과 lysine 소화율과의 상관관계가 상대적으로 높아 DDGS의 품질을 평가하는데 이런 색도계가 사용되고 있다(USGC, 2006). | |
옥수수의 가공 공정에는 무엇이 있는가? | 옥수수의 가공 공정에는 건식가공(dry milling)과 습식가공(wet milling)이 있으며, 건식 공정을 이용한 옥수수에서는 에탄올 34.4%, 이산화탄소 34% 및 DDGS 31. | |
DDGS를 사료로 이용하기 위해 고려해야 할 특성에는 무엇이 있는가? | DDGS를 사료로 이용하기 위해 고려해야 할 특성으로는 색깔, 냄새, 입자도, 밀도, pH, 유동성, 저장 안정성 및 흡습성 등이 있다. DDGS의 색은 이러한 특성 중의 하나로 매우어두운 갈색에서 매우 밝은 노란색까지 다양하다. |
