柑橘皮渣对1～21日龄四川白鹅生长性能及血清生化指标的影响

Effects of Citrus Pomace on Growth Performance and Serum Biochemical Parameters of Sichuan White Geese at 1 to 21 Days of Age

本试验旨在探索柑橘皮渣对1-21日龄四川白鹅生长性能及血清生化指标的影响。选用828只1日龄四川白鹅,用单因子试验设计,随机分成6组,每个组6个重复,每个重复23只鹅。各组分别饲喂含柑橘皮渣0（对照组）、2%、4%、6%、8%和10%的等代谢能、等粗蛋白质、等氨基酸的玉米-豆粕型饲粮。试验期21 d。结果表明：1）6%组料重比显著低于对照组（P〈0.05）,末重和平均日增重呈先增加后降低趋势。2）与对照组相比,8%组血清高密度脂蛋白含量显著提高（P〈0.05）;10%组血清总胆固醇含量显著提高（P〈0.05）。3）柑橘皮渣对鹅血清生化指标无显著影响（P〉0.05）。由此可见,饲粮柑橘皮渣添加量为6%时,对1-21日龄四川白鹅生产性能有较好的促进作用。

This experiment was conducted to study the effects of citrus pomace on growth performance and serum biochemical parameters of Sichuan white geese at 1 to 21 days of age. A total of 828 one-day-old Sichuan white geese were distributed into one-factor experiment for 6 groups with 6 replicates and 23 ducks per replicate. Six corn-soybean meal type diets were perpared with the similar metabolizable energy,crude protein and acid amino,and the citrus pomace level in those diets was 0（ control group）,2 %,4 %,6 %,8 % and 10 %,respectively. The experment lasted for 21 days. The results showed as follows： 1） the feed / gain of 8 % group was significantly lower than that of the control group,the final weight and average daily gain showed a firstly increased and then decreased tendency. 2） Compared with the control group,the serum high-density lipoprotein content of 8 % group was significantly improved（ P〈0. 05）,and the serum total cholesterol content of10 % group was significantly improved（ P〈0. 05）. 3） Citrus pomace had no significant effects on serum biochemical parameters（ P〉0. 05）. In conclusion,6 % citrus pomace added in the diet can improve the growth performance of Sichuan white geese at 1 to 21 days of age.
