摘　　要：试验旨在筛选适宜产蛋期太行鸡的专用预混料,研究预混料对产蛋期太行鸡生产性能、蛋品质、血清抗氧化能力与经济效益的影响。选取280日龄健康太行鸡432只,随机分为6组,每组6个重复,每个重复12只。A组太行鸡(对照组)饲喂商品蛋鸡预混料,D组(100%预混料)饲喂参照鸡饲养标准与太行鸡生理特点所配制预混料,B组、C组、E组、F组太行鸡在D组基础上将维生素与微量元素水平降低50%、25%与提高25%、50%。结果表明,与对照组相比,B、C组太行鸡产蛋率组均显著下降(P<0.05),料蛋比显著升高(P<0.05);F组蛋壳强度显著高于B、C组(P<0.05);与对照组相比,B、C组太行鸡血清中谷胱甘肽过氧化物酶(GSH-Px)活性显著降低(P<0.05);B组总抗氧化能力(T-AOC)显著降低(P<0.05);D组、E组、F组经济效益分别较对照组高6.00%、3.65%、0.01%,B、C组经济效益较对照组低16.39%、16.61%。研究表明,D~F组预混料可保证产蛋高峰期太行鸡的生产性能、蛋品质、血清抗氧化能力,D组所获经济效益最高,可作为产蛋高峰期太行鸡专用预混料。The experiment was to screen the special premix for Taihang chickens during the laying period, the effect of the premix on the production performance, egg quality, serum antioxidant capacity and economic benefits of Taihang chickens during the laying period were studied. 432 healthy 280-day-old Taihang chickens were selected and randomly divided into six groups, with six replicates in each group and 12 chickens in each replicate. Chickens in group A(control group) were fed with premix for commercial laying hens, and chickens in group D(100% premix) were fed with premix prepared according to chicken breeding standards and the physiological characteristics of Taihang chickens. Taihang chickens in group B, group C, group E and group F were fed with vitamin and trace element levels reduced by 50% and25% and increased by 25% and 50% on the basis of group D. The results showed that compared with the control group, the egg production rate of group B and group C significantly decreased(P<0.05), and the feed-to-egg ratio significantly increased(P<0.05). The eggshell strength of group F was significantly higher than that of group B and group C(P<0.05).Compared with the control group, serum glutathione peroxidase(GSH-Px) activity in group B and group C was significantly reduced(P<0.05). The total antioxidant capacity(T-AOC) of group B was significantly reduced(P<0.05).The economic benefits of group D, group E and group F were 6.00%, 3.65% and 0.01% higher than those of control group,respectively. The economic benefits of group B and group C were lower than the control group by 16.39% and 16.61%.The experiment indicates that the premix D~F can guarantee the normal production performance, egg quality and serum antioxidant capacity of Taihang chickens during the peak laying period. Group D has the highest economic benefit and can be used as a special premix for Taihang chickens during the peak laying period.
