不同脂肪源对朗德鹅产肝性能及血液生化指标的影响

Effect of Differential Fat Sources on Liver Production and Blood Biochemical Indices of Landes Geese

试验采用单因子设计方案,将450只70日龄同批孵化、体重相近、健康的朗德鹅随机分成3组,其中Ⅰ组为对照组,Ⅱ、Ⅲ组分别为试验组 每组3个重复,每个重复50只。Ⅰ、Ⅱ、Ⅲ组在超饲养日粮基础上分别添加2%的鹅油、2%豆油和2%玉米油,研究不同脂肪源对朗德鹅填饲3周后产肝性能及血液生化指标的影响。试验结果表明,与Ⅰ组相比,Ⅱ、Ⅲ组肥肝均重和肝体比显著增加（P〈0.05）,Ⅱ、Ⅲ组之间差异不显著（P〉0.05） 料肝比Ⅱ、Ⅲ组均低于Ⅰ组,但差异不显著（P〉0.05）。不同脂肪源对填饲朗德鹅血清TG、CHOL、HDL和LDL影响不显著,其浓度填饲后比填饲前均增加2~4倍。LDL、TG和CHOL浓度虽显著增加,但各组间保持稳定。

This research adopted the experimental design method of the single factor, randomly deviding 450 ten-week Landes geese into 3 groups, which were raised well in the same batch with similar weight. The first group was control group, others were testing group（each of them contained 50 geese with 3 repetitions）. In addition to overfeed, 2% of goose oil（group 1）, 2% of bean oil（group 2） and 2% of corn oil（group 3） were added into. The effect of differential fat sources on liver pro- duction and blood biochemical indices of Landes geese was investigated after three weeks of overfeed. The results of the test were as follows,the liver weight and the liver weight/body weight of the group 1 and group 2, group 3 were significantly in- creaseed（P〈0.05） ,but group 2 and group 3 were not significant （P〉0.05） ;the feed intake/liver weight of group 2 and group 3 were lower than group 1,but the difference were not significant （P〉0.05）. The effect of differential fat sources on TG, CHOL, HDL and LDL of the Landes＇blood were not significant. After force-feeding, the concentration increased 2 to 4 times than before force-feeding. The concentration of LDL,TG and CHOL increased significantly,but every group was keeping stable.
