本试验旨在研究玉米型饲粮和小麦型饲粮对肉仔鸡生长性能、肉品质、血浆生化指标和脂质代谢的影响。选取健康的1日龄爱拔益加肉仔鸡公雏180只，随机分成2个组，分别采食玉米型饲粮和小麦型饲粮，每组6个重复，每个重复15只鸡。试验期42 d。结果表明：与玉米型饲粮相比，饲喂小麦型饲粮的肉仔鸡，1）生长前期（1～21日龄）和全期（1～42日龄）平均日增重（ADG）显著增加（P<0.05），生长前期死亡率显著降低（P<0.05）；2）42日龄的腹脂率显著降低（P<0.05）；3）42日龄胸肌肌肉的红度（a*）45 min和a*24 h值显著降低（P<0.05），亮度（L*）45 min值增加（P=0.096）；4）21和42日龄血浆总胆红素含量显著降低（P<0.05）；21日龄血浆总蛋白和白蛋白含量显著增加（P<0.05），21日龄血浆谷氨酸氨基转移酶活性显著降低（P<0.05）；42日龄血浆尿酸含量显著增加（P<0.05）；5）21和42日龄血浆甘油三酯含量显著降低（P<0.05）；42日龄血浆总胆固醇含量显著降低（P<0.05）。由此可见，本试验条件下，与玉米型饲粮相比，小麦型饲粮改善了肉仔鸡的生长性能、脂质代谢和健康状态，降低了腹脂率。
The current study was to investigate the effects of corn-type diet and wheat-type diet on growth performance, meat quality, plasma biochemical parameters and lipid metabolism of broilers. A total of 180 one-day-old male Arbor Acres broilers were randomly assigned to 2 groups which fed with corn-type diet and wheat-type diet, respectively. Each group had 6 replicates with 15 broilers in each replicate. The experiment lasted for 42 days. The results showed that: broilers fed with wheat-type diet compared with corn-type diet, 1) the average daily gain (ADG) in starter phase (1 to 21 days of age) and whole phase (1 to 42 days of age) was significantly increased (P<0.05), and the mortality in starter phase was significantly decreased (P<0.05); 2) the abdominal fat rate was significantly decreased at 42 days of age; 3) the redness (a*)45 min and a*24 h values were significantly decreased (P<0.05), the lightness (L*)45 min value was increased (P=0.096); 4) the plasma total bilirubin content was significantly decreased at 21 and 42 days of age (P<0.05), the contents of total protein and albumin in plasma were significantly increased on at 21 days of age (P<0.05), the plasma alanine aminotransferase activity was significantly decreased at 21 days of age (P<0.05), the plasma uric acid content was significantly increased on at 42 days of age (P<0.05); 5) the plasma triglyceride content was significantly decreased at 21 and 42 days of age (P<0.05), the plasma total cholesterol content was significantly decreased at 42 days of age (P<0.05). Therefore, in the current study, compared with corn-type diet, wheat-type diet can improve growth performance, lipid metabolism status and healthy of broilers, and decrease abdominal fat and meat color of breast muscle.
