杜仲叶对芦花鸡生长性能及肉质的影响

Effects of Eucommia ulmoides Leaf Powder in Diet on Growth Performance and Meat Quality of Luhua Chicken

摘要: 本试验旨在研究饲粮中不同添加量杜仲叶粉对芦花鸡生长性能、屠宰指标、血液生化指标以及肉品质等影响，探讨其在养鸡行业的应用效果。试验选取4周龄健康、体重约为300 g/羽的芦花鸡160羽，随机分成4组，每组40羽。对照组饲喂基础饲粮，试验组在其基础上分别添加1%、3%和5%杜仲叶粉，试验期70天。结果表明：与对照组相比，试验组芦花鸡平均日增重降低，料重比升高(P < 0.01)；各试验组中，芦花鸡末重减小(P < 0.05)，腹脂率和低密度脂蛋白胆固醇含量降低(P < 0.01)，并且蛋白质含量明显提高(P < 0.01)；另外不同添加量的杜仲叶粉也会引起黄酮、硒和氨基酸含量等成分的变化。综合考虑，饲粮中添加3%杜仲叶粉更适合芦花鸡生长性能及肉质的改善。

Abstract: This experiment was conducted to study the effect of adding different concentration of Eucommia ulmoides leaf powder on growth performance, slaughter index, blood biochemical index, muscle quality related indicators of Luhua chicken in broilers. It was very necessary to explore the application of Eucommia ulmoides leaf in the chicken industry. In the experiment, 160 healthy Luhua chicken about 4-week-old, 300 g each were randomly divided into four groups and each group was 40. Chicken in the control group were fed a basal diet, and others were fed the basal diets supplemented with 1%, 3% and 5% Eucommia ulmoides leaf powder. The feeding trail lasted for 70 days. The experimental results showed as follow: compared with the control group, the average daily gain of the Luhua chicken in the experimental group decreased, and the feed-weight (F/W) ratio increased (P < 0.01). In each test group, the final weight of the chicken decreased (P < 0.05), the abdominal fat percentage and low density lipoprotein cholesterol content decreased (P < 0.01), and protein content increased significantly (P < 0.01). In addition, different amount of Eucommia ulmoides leaf powder also caused changed in flavonoids, selenium and amino acid content. Based on the above experimental results, adding 3.0% Eucommia ulmoides leaf powder to the diet was suitable for the growth performance and meat quality of the Luhua chicken.
