摘要

．本试验旨在评价饲粮中添加槲皮素对蛋鸡生产性能、繁殖性能、肠道细菌数量和血液生化指标的影响。选取200只28周龄的蛋鸡，随机分为4个处理(每处理10只，每处理5个重复)，第1组为对照(基础饲粮中不添加任何添加剂)，第2、3和4组分别饲喂在基础饲粮中添加300、600和1200 mg槲皮素/kg饲料的饲粮。饲粮添加300和600 mg槲皮素/kg饲料可提高产蛋量和蛋质量(P≤0.001)，对蛋重和采食量无影响，但提高了饲料系数。提高了蛋壳厚度、哈氏单位和蛋黄颜色评分

Nutritional and physiological evaluation of quercetin as a phytogenic feed additive in laying hens

. The objective of the current study was to evaluate the effect of dietary quercetin supplementation on productive and reproductive performance, intestinal bacterial count, and blood biochemical parameters of laying hens. A total of 200 hens at 28 weeks of age were randomly assigned to four treatments (10 hens per treatment, 5 replicates each), group 1 was treated as control (basal diet without any supplementation), group 2, 3 and 4 were fed diets supplemented with 300, 600 and 1200 mg quercetin/kg feed, respectively. Egg production and egg mass increased ( P ≤ 0.001) as a result of dietary sup plementation with 300 and 600 mg quercetin/kg feed, while egg weight and feed intake were not affected, but the feed conversion ratio improved. Shell thickness, Haugh unit and yolk colour score were improved

期刊介绍： Journal of Animal and Feed Sciences (JAFS, J. Anim. Feed Sci.) has been published by the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences in Jabłonna (Poland) since 1991. It is a continuation of the Polish-language journal Roczniki Nauk Rolniczych. Seria B, Zootechniczna published by the Polish Academy of Sciences since 1969. JAFS is an international scientific journal published quarterly, about 40 papers per year including original papers, short communications and occasionally reviews. All papers are peer-reviewed and related to basic and applied researches in the field of animal breeding and genetics, physiology of nutrition, animal feeding, feed technology and food preservation. The journal distinguishes the multidisciplinary nature of physiological and nutritional sciences and so includes papers specialized in all fields connected with animal well-being, including molecular and cell biology and the emerging area of genetics.
