| 摘 要： | 本试验旨在研究饲粮添加包被苯甲酸对肉鸡腿部健康和垫料理化性质的影响。选取2 400只1日龄爱拔益加肉仔鸡,随机分为2组,每组12个重复,每个重复100只(公母各占1/2)。对照组饲喂基础饲粮(颗粒料),试验组在对照组的基础上添加500 g/t包被苯甲酸。试验期为35 d。35日龄时每个重复随机抓取10只肉鸡进行脚垫和跗关节评估;收集各个重复垫料样品进行垫料湿度、p H和总氮含量的测定。结果表明:饲粮添加500 g/t包被苯甲酸显著降低了肉鸡的脚垫和跗关节损伤程度(P0.05),同时显著降低了垫料的p H和总氮含量(P0.05),对垫料湿度没有显著影响(P0.05)。由此可见,饲粮添加包被苯甲酸可降低肉鸡脚垫和跗关节损伤,同时改善垫料的理化性质,提高肉鸡饲养过程中的福利水平。

Effects of Coated-Benzoic Acid on Leg Health of Broilers and Physicochemical Property of Bedding |
| |
| Abstract: | An experiment was conducted to evaluate the effects of dietary coated-benzoic acid on leg health of broilers and physicochemical property of bedding. A total of 2 400 Arbor Acres chicks were randomly distribu-ted into 2 groups with 12 replicate pens per group and 100 birds ( male∶female was 1∶1) per pen at 1 day of age. The broilers in control group were fed basal diets, and in experimental group were fed basal diets supple-mented with 500 g/t coated-benzoic acid. The trial lasted for 35 d. At 35 days of age, 10 chicks per pen were selected for footpad and hock assessments, and the humidity, pH and total nitrogen ( TN) content of bedding samples were measured in each pen. The results showed that dietary supplementation of 500 g/t coated-benzoic acid significantly reduced the occurrence of footpad and hock injury ( P<0.05) . Moreover, coated-benzoic acid significantly decreased the pH and TN content ( P<0.05) of bedding whereas the humidity remained unaffected ( P>0.05) . In conclusion, the current research reveals that dietary supplementation of coated-benzoic acid de-creases the incidence of footpad and hock injury and considerably influences the physicochemical property of bedding. The welfare of the broilers is improved by coated-benzoic acid. |
