3种复方保健剂在种鸡中的应用效果

Effects of three compound health care agents on breeding hens

【目的】探讨3种复方保健剂在种鸡中的应用效果。【方法】选取产蛋日龄相同、产蛋率相近的384只海蓝褐种鸡,将其分成4组:对照组、牛膝复方制剂(TARCP)组、女贞子复方制剂(LLACP)组和麻黄复方制剂(CECP)组,每组96只,12个重复,每个重复8只。对照组鸡喂以生产常规饲粮,其他组鸡在常规饲粮中分别添加1%TARCP、1%LLACP、0.5%CECP后饲喂。先进行7d的预试验,对鸡群进行调整,消除组间产蛋率明显差异后,进入为期8周的正式试验,通过对鸡群健康指标、生产性能指标、血清生化指标和组织生化指标的测定,考察3种复方制剂的应用效果。【结果】(1)LLACP组鸡产蛋率显著高于对照组(P<0.05);CECP组鸡产蛋量极显著多于对照组(P<0.01),TARCP、LLACP组鸡产蛋量显著多于对照组;TARCP、CECP组饲料转化率显著高于对照组;CECP组鸡种蛋受精率极显著高于对照组,LLACP和TARCP组鸡种蛋受精率显著高于对照组。(2)LLACP组鸡血清总蛋白质和总胆固醇含量显著高于对照组(P<0.05),TARCP、LLACP和CECP组鸡血清超氧化物歧化酶活性显著或极显著高于对照组,LLACP组鸡血清总抗氧化力显著高于对照组,TARCP、CECP组鸡血清谷丙转氨酶活性显著低于对照组和LLACP组,TARCP、LLACP和CECP组鸡血清丙二醛含量极显著低于对照组。(3)LLACP和CECP组鸡肝丙二醛含量显著低于对照组和TARCP组(P<0.05),LLACP组鸡胸肌和鸡蛋超氧化物歧化酶活性极显著高于对照组(P<0.01),LLACP和CECP组鸡胸肌和鸡蛋丙二醛含量极显著低于对照组。【结论】3种复方制剂能提高种鸡的产蛋机能和饲料转化率,增强种鸡的抗氧化能力,提高种蛋受精率;3种复方制剂在种鸡中的应用效果为LLACP>CECP>TARCP。

[Objective] The effects of three compound health care agents on breeding hens were studied. [Method] A total of 384 Hy line variety brown breeders with same egg laying age and similar laying rate were divided into four groups： control, TARCP, LLACP and CECP. Each group had 96 hens and 12 re peats,with 8 hens in each repeat. The control group breeders were fed with the conventional diet. TARCP group breeders were fed with the conventional diet supplemented 1 % twotooth achyranthes root compound preparation （TARCP）. LLACP group breeders were fed with the conventional diet supplemented 1% Liustrum lucidum ait compound preparation （LLACP）. CECP group breeders were fed with the convention al diet supplemented 0.5 % Chinese ephedra compound preparation （CECP）. After 7 d protest for elimina ting difference in egg production rate among groups, the effects of three agents were investigated in the for real experiment for 8 weeks. [Result] （1） The laying rate of LLACP group breeders was higher than the control group （P〈0.05）. The egg production of CECP breeders was highly significantly higher than the control group （P〈0.01）. The egg production of TARCP and LLACP breeders was significantly more than the control group. FCR of TARCP and CECP group was significantly higher than that of the control group. Egg fertilization rate of CECP was very significantly higher than the control group, and the egg fertilization rate of LLACP and TARCP breeders was significantly higher than the control group. （2） TP and TC in se rum of LLACP breeders were significantly higher than the control group （P〈0. 05）. SOD activities in set um of TARCP,LLACP and CECP breeders were significantly or very significant （P〈0. 01） higher than that of the control group. T AOC in serum of LLACP breeders was significantly higher than group. GPT activities in serum of TARCP and CECP breeders were significantly lower than the LLACP. MDA in serum of TARCP, LLACP and CECP breeders was significantly less than group. （3） MDA in liver of LLACP and CECP breeders was significantly lower than the the control control and the control control and TARCP group （P〈0.05）. SOD activities in muscle and egg of LLACP breeders were very significantly higher than the control group （P〈0.01）. MDA contents in muscle and egg of LLACP and CECP breeders were very significantly lower than in the control group. [Conclusion] The three compound preparations could improve the egg production performance of breeders and FCR,strengthen the antioxidant power and enhance the egg fertilization rate. The overall performance of the compound preparations was in the order of LLACP〉CECP〉TARCP.
