The objective of this study was to evaluate the effects of inclusion rates of corn dried distillers' grains with solubles (DDGS) on broiler chicken diets from d 0 to 21, and its effects on growth performance, intestinal morphology, blood metabolites, carcass and cut yields, and meat quality. A total of 980 one-day-old male broiler chickens were assigned to 7 diets (0, 10, 40, 70, 100, 130, and 160 g DDGS/kg) with 7 pens per treatment and 20 broiler chickens per pen in a completely randomized design. Data were analyzed by orthogonal polynomials, and the regression analysis was performed when a linear or quadratic effect was statistically significant; significance was considered at a level of 5%. Experimental diets with DDGS were included from d 0 to 21, and in the periods from d 21 to 33 and 33 to 42, common diets without DDGS were provided. Inclusion of DDGS in the broiler chicken diets did not affect the weight gain, feed conversion ratio, carcass, and cut yields. Feed intake was not altered from d 0 to 21, however, it had a quadratic effect from d 0 to 42 (P = 0.013). There was a linear increase (P < 0.001) in the relative weight of large intestine at d 21. Jejunal villi height was quadratically affected (P < 0.001), and the lowest villus height was observed at 91.54 g DDGS/kg. There was a linear reduction in jejunal crypt depth (P < 0.001) and a quadratic effect on villus: crypt ratio (P < 0.001) where the lowest value was estimated at 46 g DDGS/kg and 6.89 for villus: crypt ratio. There was a quadratic effect for breast meat pH 15 min postmortem (P = 0.017) and the lowest value was estimated at the inclusion of 79.25 g DDGS/kg and the pH 6.47. The DDGS can be included in broiler chicken diets up to 160 g DDGS/kg from d 0 to 21 without affecting growth performance, carcass and cuts yield, and meat quality of broiler chickens up to d 42.

这项研究的目的是评估d 0到21天玉米干酒糟含DDGS对肉鸡日粮的影响及其对生长性能，肠道形态，血液代谢产物，car体和切块的影响。产量和肉质。总共980只1日龄的雄性肉鸡分配了7种日粮（DDGS / kg分别为0,10,40,70,100,130和160 g DDGS / kg），每次处理7支，每支20只肉鸡。完全随机的设计。通过正交多项式分析数据，当线性或二次效应具有统计学意义时进行回归分析。显着性水平为5％。从d 0到21包括DDGS的实验饮食，在d 21到33和33到42的时期内，提供了没有DDGS的普通饮食。在肉鸡日粮中添加DDGS不会影响增重，饲料转化率，car体和减产。采食量在d 0到21之间没有变化，但是从d 0到42有二次作用（P = 0.013）。在第21天，大肠的相对重量线性增加（P <0.001），空肠绒毛高度受到二次影响（P <0.001），最低的绒毛高度为91.54 g DDGS / kg。空肠隐窝深度呈线性下降（P <0.001），对绒毛：隐窝比率有二次效应（P <0.001），其中最低值估计为46 g DDGS / kg，绒毛：隐窝比率为6.89。死后15分钟pH值对胸肉有二次效应（P = 0.017），估计最低值是在加入79.25 g DDGS / kg和pH 6.47的情况下。从d 0到21，DDGS可以包含在高达160 g DDGS / kg的肉鸡日粮中，而不会影响d 42以前的肉鸡的生长性能，car体和切块产量以及肉质。
