摘要

光照影响蛋鸡的福利和生产。本研究研究了一种新型LED光系统对蛋鸡血液生理指标的影响。在两个试验中，每个试验将320个蛋鸡分配给16组，每组20只鸡。处理包括原型LED照明(两个房间)和传统的2700 K LED灯泡(两个房间)。在每个采样日，立即采集血样并进行分析。结果表明，只有少数生理变量受到治疗的影响，但年龄对大多数被检查的变量有影响。治疗或年龄对血浆皮质酮没有影响，表明生理应激水平相似。

Age-related effects of high-frequency LED lighting in laying hens. Part 1: blood physiological variables

Abstract Light impacts layer hen's welfare and production. This study investigated the effects of a novel LED light system on blood physiological variables in laying hens. In each of the two trials, 320-layer pullets were allocated to 16 groups of 20 birds. Treatments included the prototype LED lighting (two rooms) and the conventional 2700 K LED bulbs (two rooms). On each sampling day, blood samples were collected and analyzed immediately. Results show that only a few physiological variables were affected by treatments, but age had effects on most examined variables. No effects of treatments or age on plasma corticosterone signify a similar level of physiological stress.

期刊介绍： Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
