热应激条件下中药复方对蛋鸡血清中部分离子浓度的影响

Effects of Compound Chinese Herbal Medicine on Some Serumion Concentrations of Laying Hens under High Temperature

试验旨在通过日粮中添加中药复方研究其对慢性热应激状态下蛋鸡的血液生化指标的影响,并对其调控机制作初步的探讨。本试验选用60周龄海兰褐蛋鸡250只,随机分为5组,每组50只,试验1～4组日粮中分别添加1%中药复方1、1%中药复方2、1%中药复方3、0.04%维生素C,第5组为空白对照组。分别在试验期的第14、28、42、56天检测蛋鸡血清中钙、磷、钠、钾离子浓度。试验结果显示,3种中药复方都可以使血清中钙、磷、钠、钾4种离子的浓度升高,有此可见中药复方可维持机体的血液生化指标稳定,提高血清中钙、磷、钠、钾含量,提高机体的热耐力,而且中药复方的效果优于维生素C。

The experiment was designed to investigate the effect of Chinese herb medicinal prescriptions on serum ion con- centration of laying hens under chronic high temperature. In the experiment, 250 healthy Hyline Brown laying hens, aged 60- weeks,were allocated to 5 groups at random and each group included 50 laying hens respectively. The groups 1 to 4 were with the basic diets containing 1% concentrations of traditional Chinese herbal compound 1,traditional Chinese herbal compound 2, traditional Chinese herbal compound 3,0.04% vitamin C respectively, the group 5 was control group. Feed intake,egg quanti- ty,egg weight,soft broken egg ratio,and the death number were recorded every day,use the kit detected serum ion concentra- tion. The results indicated that Chinese herb medicinal prescriptions not only enhance production performance, but also boost the Ca,K,P,Na,in blood of laying hen,and enhance heat-resisting ability better than vitamin C.
