| 摘 要： | 【目的】研究不同中草药添加剂对滩羊泌乳性能的影响及作用机理,为滩羊中草药饲料添加剂的配制提供参考。【方法】将24只妊娠滩羊母羊随机分为A、B、C、D4组,其中A组为对照组,B、C、D组为试验组,每组6只,每只为1个重复。对照组饲喂基础日粮,试验组B、C、D分别饲喂基础日粮中添加Ⅰ、Ⅱ、Ⅲ3种中草药添加剂后混合而成的日粮;饲喂期为产前10d至产后15d,其中产前添加剂饲喂量为每只25g/d,产后为50g/d。试验期每天测量母羊产奶量,从试验期第3天开始,每5d采1次血样,测定生长激素(Growth hormone,GH)和催乳素(Prolac-tin,PRL)含量。【结果】3种中草药饲料添加剂,均可不同程度地提高母羊产后1~15d的日产奶量,且具有后续效应,其中B、C、D试验组1~15d的日产奶量分别较对照组提高了6.93%,1.72%和5.21%;1~30d的日产奶量分别较对照组提高了5.76%,2.49%和4.38%,B、D组与对照组差异显著(P0.05)。3种中草药饲料添加剂均可提高血浆GH含量,但不同的中草药添加剂的提高程度略有差异;不同的中草药饲料添加剂对血浆PRL含量会产生不同的影响,在整个试验期,B、C组母羊血浆的PRL含量始终高于对照组,而D组的PRL含量在用药期低于对照组,但停药后又高于对照组。【结论】中草药饲料添加剂通过调节血浆PRL和GH含量改善滩羊的泌乳性能。

| Abstract: | Objective] The research was to study the effect of different Chinese herbal additives on milk performance of Tan-yang ewes and mechanism of action to provide theoretical references for Tan-yang ewes to develop Chinese herbal additive.Method] 24 selective pregnant ewes were divided randomly into four groups:control(group A)and others(group B,group C,group D)were experimental groups,and 6 replication for each group and an ewe for each replication.The ewes in control group was fed basel diet,and others were ... |
