Currently, in animal nutrition, the replacement of synthetic substances with natural ones was expected to improve animal health. The aim of the present study was to evaluate the effects of a dietary brown seaweed and plant polyphenol mixture in adult male rabbits on the haematological profile and antioxidant markers. Twenty-four adult male rabbits were divided into three experimental groups receiving a control diet (C) or diets supplemented with 0.3% (T1) and 0.6% (T2) of a feed additive containing brown seaweed ( spp.) and plant extracts of seaweed origin. The trial lasted for 90 days. A lower potassium concentration was observed at 30 days in the T2 group, compared with the T1 and C groups. An increase in the antioxidant status was observed ( < 0.05) from day 60 of the trial in the rabbits fed diets with an algae-polyphenolic supplement (T1 and T2 groups). Concluding, the diet supplementation of brown seaweed and polyphenol stimulates the antioxidant status of the blood, however, it does not affect the haematological profile.
目前，在动物营养领域，人们期望用天然物质替代合成物质来改善动物健康。本研究的目的是评估日粮中添加褐藻和植物多酚混合物对成年雄性家兔血液学指标和抗氧化指标的影响。将24只成年雄性家兔分为三个实验组，分别给予对照日粮（C组）或添加了0.3%（T1组）和0.6%（T2组）含褐藻（ 种）和海藻源植物提取物的饲料添加剂的日粮。试验持续90天。与T1组和C组相比，T2组在30天时血钾浓度较低。从试验第60天起，在饲喂含藻类 - 多酚补充剂日粮的家兔（T1组和T2组）中观察到抗氧化状态增加（ ＜0.05）。总之，日粮中添加褐藻和多酚可刺激血液的抗氧化状态，然而，它不影响血液学指标。
