摘要
本试验根据乌骨鸡的生理特点,选用以何首乌、黑芝麻、血余炭等为主要成分的中草药,由人药乌发丸的配方加以改进,制成本试验用的3种复方中草药添加剂,探讨中草药添加剂对乌骨鸡体内黑色素含量的影响。选用1日龄的泰和乌骨鸡,分为对照组(基础日粮)、试验Ⅰ组(基础日粮+1%Ⅰ号中草药)、试验Ⅱ组(基础日粮+1%Ⅱ号中草药)和试验Ⅲ组(基础日粮+1%Ⅲ号中草药),共4组,每组设3个重复,每个重复15只鸡,共180只。分0～4周龄、5～8周龄、9～12周龄3个阶段,通过饲养试验、屠宰实验,研究各不同中草药添加剂对泰和乌骨鸡体内黑色素含量的影响。结果显示:(1)4周龄时试验组各组织(胸肌、腿肌和皮肤)中黑色素含量均比对照组高,但差异不显著(P>0.05);4周龄和12周龄时不同组织间黑色素含量差异显著(P<0.05),但8周龄时不同组织间黑色素含量差异不显著(P>0.05)。除8周龄试验Ⅱ组的皮肤及12周龄时试验Ⅱ组的腿肌黑色素含量略低于对照组外,其他试验组各组织中黑色素含量均高于对照组,但差异不显著(P>0.05)。在各周龄不同中草药添加剂组间组织黑色素含量差异不显著(P>0.05),不同添加剂与不同组织间的互作效应也不显著(P>0.05)。(2)胸肌黑色素含量在不同周龄间差异不显著(P>0.05),中草药添加剂组胸肌黑色素含量显著高于对照组(P<0.05),但不同添加剂组之间差异不显著(P>0.05)。不同周龄间腿肌黑色素含量差异显著(P<0.05),其中12周龄黑色素含量显著低于4周和8周龄,各处理组间差异不显著(P>0.05)。不同周龄间皮肤黑色素含量差异显著(P<0.05),其中12周龄黑色素含量显著低于4周龄,各处理组间差异不显著(P>0.05)。所有组织黑色素含量随日龄的增大而逐渐减少,且不同添加剂与不同周龄间的互作效应不显著(P>0.05)。
Three different Chinese herbal additive prescriptions were formulated with some modification mainly from Polygonum multiflorum Thumb （Heshouwu）,Sesamum indic um L（Heizhima）and Crinis Carbonisatus （Xueyutan）based on the Black-hair prescription and physiology of Taihe silky fowl.One hundred and eighty of one-day old Taihe silky fowls were randomly allotted to 4 groups with 3 replicates of 15 birds each.Birds were fed the basal diets （control group）,basal diets supplemented with 1.0 % Chinese herbal additive prescription Ⅰ （group Ⅰ ）, 1.0 % Chinese herbal additive prescription Ⅱ （group Ⅱ ） and 1.0 % Chinese herbal additive prescription Ⅲ （group re）for three periods（0 - 4,5 - 8 weeks of age and 9 - 12 weeks of age）,respectively.Breeding and slaughtering trials were conducted to investigate the effects of different Chinese herbal additive prescriptions on the melanin content in Taihe silky fowls.The results showed as follows： （1）The Chinese herbal additive treatment groups had higher melanin content in pectoral muscle,leg muscle and skin than control group but no significant difference being observed （P 〉 0.05） at 4 weeks of age.The melanin content was significantly different between different tissues at 4 and 12 weeks of age （P 〈 0.05）,whereas no significant difference was observed between different tissues at 8 weeks of age.The melanin content in skin of Chinese herbal additive treatment groups was higher than that of control group except for group Ⅱ in which the melanin content was slightly lower than that of control group at 8 and 12 weeks of age, but no significant difference was observed（P 〉 0.05）.The melanin content between all Chinese herbal additive treatment groups,as well as the cross effects between groups and tissues,were not significantly different during whole experimental periods （P 〈 0.05）. （2）Melanin content in pectoral muscle was not significantly different between different weeks of age （P 〉 0.05）.Melanin content in
