Abstract

1. This study assessed the addition of dried stinging nettle (SN) leaves at 0%, 2.5% and 5.0% in feed on egg production, egg quality, chemical composition and antioxidant content in eggs from laying hens.2. Seventy-two Hy-Line Brown laying hens, housed in 36 enriched layer cages, were used in the study from 43 to 47 weeks of age. Feeding dry SN leaves did not affect (p > 0.05) egg production variables.3. Dietary SN inclusion linearly increased (p < 0.001) carotenoid content more than six-fold, in addition to yellowness and redness of the yolks at the maximum inclusion. Providing eggs from hens fed carotenoid enriched diets, e.g. SN, may be used to increase carotenoids in human diets.

荨麻能提高产蛋鸡蛋黄中类胡萝卜素的含量。

1.本研究评估了在饲料中添加 0%、2.5% 和 5.0% 的干荨麻（SN）叶对蛋鸡产蛋量、鸡蛋质量、化学成分和鸡蛋中抗氧化剂含量的影响。 2. 本研究使用了 72 只饲养在 36 个强化蛋鸡笼中的 43 至 47 周龄海线褐蛋鸡。饲喂干燥的 SN 叶片不会影响（p > 0.05）鸡蛋产量变量。 3.膳食中添加 SN 会线性增加（p 例如，SN 可用于增加人类膳食中的类胡萝卜素。

期刊介绍： From its first volume in 1960, British Poultry Science has been a leading international journal for poultry scientists and advisers to the poultry industry throughout the world. Over 60% of the independently refereed papers published originate outside the UK. Most typically they report the results of biological studies with an experimental approach which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: anatomy, embryology, biochemistry, biophysics, physiology, reproduction and genetics, behaviour, microbiology, endocrinology, nutrition, environmental science, food science, feeding stuffs and feeding, management and housing welfare, breeding, hatching, poultry meat and egg yields and quality.Papers that adopt a modelling approach or describe the scientific background to new equipment or apparatus directly relevant to the industry are also published. The journal also features rapid publication of Short Communications. Summaries of papers presented at the Spring Meeting of the UK Branch of the WPSA are published in British Poultry Abstracts .
