摘要
旨在探讨姜黄对蛋鸡生产性能、鸡蛋品质和血清生化指标的影响。选择体重、产蛋率相近的健康罗曼褐蛋鸡48只,随机分为试验组和对照组。试验组日粮中添加1%姜黄粉,对照组饲喂基础日粮,试验期为48 d。测定并比较2组蛋鸡的生产性能指标、鸡蛋品质指标和血清生化指标。结果表明:试验组蛋鸡的采食量和产蛋率高于对照组(P>0.05),料蛋比低于对照组(P>0.05);试验组鸡蛋的蛋白质含量显著高于对照组(P<0.05),每克蛋黄胆固醇含量和鸡蛋胆固醇含量均极显著低于对照组(P<0.01);试验组蛋鸡的高密度脂蛋白胆固醇(HDL-C)极显著高于对照组(P<0.01),低密度脂蛋白胆固醇(LDLC)、甘油三酯(TG)和总胆固醇(TC)含量显著或极显著低于对照组(P<0.05或P<0.01)。姜黄具有降低鸡蛋胆固醇含量、改善蛋鸡脂代谢功能的作用。
This study aimed to assess the effect of dietary supplementation of Curcuma longa on production performance, egg quality and serum biochemical indexes of laying hens. A total of 48 healthy Roman brown shell laying hens were chosen and averagely and randomly assigned to one of the two groups： an experimental group fed a special diet of feed supplemented with 1%Curcuma longa powder, and a control group fed basal diet. The experimental period lasted for 48 days. The indexes associated with production performance, egg quality and serum biochemistry of the laying hens from experimental group and control group were determined and statistically evaluated. The results showed that compared with the control group, experimental group had higher feed intake and laying rate（P〈0.05） and lower feed-egg ratio（P〉0.05）; the egg protein content of experimental group was significantly higher than control group（P〈0.05）, and the cholesterol content per 1 g of egg yolk and egg cholesterol content of experimental group was very significantly lower than control group（P〈0.01）; the experimental group had very significantly higher content of HDL-C than control group（P〈0.01） and had very significantly or significantly lower content of LDL-C, TG and TC than control group（P〈0.05 or P〈0.01）. The results obtained in this study indicated that the dietary supplementation of Curcuma longa showed the ability to reduce egg cholesterol content and to improve lipid metabolism function of laying hens.
