摘要
为研究西兰花茎叶粉对绿牧快大型草鸡生长性能和肉品质的影响,选用450只1日龄绿牧快大型草鸡,随机分成5个处理,即对照组和试验组Ⅰ、Ⅱ、Ⅲ和Ⅳ,每个处理3个重复,每个重复30只。分2个阶段饲养,第1阶段(1～28日龄)各处理分别饲喂添加0、1%、2%、3%和4%西兰花茎叶粉的日粮,第2阶段(29～56日龄)分别饲喂添加0、4%、6%、8%和10%西兰花茎叶粉的日粮。结果表明:1)添加西兰花茎叶粉对绿牧快大型草鸡的生长性能和屠宰性能均无显著影响(P>0.05);2)与对照组相比,试验组Ⅲ和Ⅳ绿牧快大型草鸡胸肌肉总色浓度、粗蛋白质和肌苷酸含量均显著升高(P<0.05);3)与对照组相比,试验组Ⅲ和Ⅳ胸肌和肝脏中胆固醇浓度均显著下降(P<0.05)。试验结果表明:添加西兰花茎叶粉可以改善肉质,降低试验鸡胸肌和肝脏胆固醇水平。
To study the effect of broccoli residues on the growth performance and meat quality in fast-growing Wenling grasschickens, 450 1-day-old chickens were randomly allocated to 5 treatments, which was the control group and trial groups Ⅰ , Ⅱ, Ⅲ and Ⅳ. Each treatment contained 3 replicates of 30 chickens per replicate. There were 2 feeding periods which fed dietary broccoli residues at the level of 0, 1%, 2%, 3%, 4% during 1-28 d and 0, 4%, 6%, 8%, 10% during 29-56 d, respectively. The results showed that： 1） there were no significant differences in the growth performance and carcass traits of fast-growing Wenling grass-chickens fed diet supplemented with broccoli residues （P〉0.05） ; 2） compared with the control group, trial groups Ⅲ and Ⅳ improved the meat color, the contents of crude protein and inosinic acid of breast muscle （P〈0.05） ; 3） adding broccoli residues to diet could decrease the concentrations of cholesterol in breast muscle, liver and serum （P〈0.05）. It was suggested that the addition of broccoli residues improved the meat quality and reduced the concentration of cholesterol in breast muscle and liver.
