(Lour.) Merr is a common traditional Chinese medicine with anti-tumor, anti-inflammatory and antioxidant activities. However, no related studies reported the potential application effect of on meat ducks. The study aims to investigate the potential effects of extract (GPE) supplementation on growth performance, carcass traits, antioxidant capacity, immunity and meat quality.
A total of 480 21-day-old female healthy ducks were randomly allocated to four treatments, each treatment containing six replicates with 20 ducks per replicate. The groups received a corn-soybean basal diet supplemented with 0 mg/kg GPE (CON), 200 mg/kg GPE (GPE200), 400 mg/kg GPE (GPE400), and 600 mg/kg GPE (GPE600), respectively. The entire experiment lasted for 7 weeks.
The results showed that dietary supplementation with 600 mg/kg GPE significantly reduced the contents of serum urea nitrogen, triglyceride (TG) and total cholesterol (TC). GPE (200, 400, and 600 mg/kg) supplementation effectively reduced the contents of IL-2 and MDA. The levels of immunoglobulin M (IgM) as well as total antioxidative capacity (T-AOC) in GPE600 group dramatically elevated in comparison with the control group. Dietary GPE supplementation considerably increased the moisture content of the breast muscle. Furthermore, dietary supplementation with GPE markedly decreased the water loss rate and shear force.
With the ban of antibiotics in poultry production, traditional Chinese medicines have been widely used in livestock and poultry production due to their high efficiency and low toxicity. extract GPE as a natural plant origin contains a series of biologically active components, including flavonoids, polyphenols, saponin, tannin and terpenoid. This study indicated that dietary supplementation with GPE can increase serum total antioxidant capacity, regulate immune function and improve meat quality to some extent in meat ducks. The recommended optimal GPE level in the diet of meat ducks is 600 mg/kg according to the results in this study.
（ Lour.） Merr是一种常见的具有抗肿瘤、抗炎和抗氧化活性的传统中药。然而，尚无相关研究报道其对肉鸭的潜在应用效果。本研究旨在探讨添加 提取物（GPE）对肉鸭生长性能、胴体性状、抗氧化能力、免疫力和肉质的潜在影响。
将480只21日龄健康雌性鸭随机分为4组，每组6个重复，每个重复20只鸭。各组分别饲喂添加0 mg/kg GPE（CON）、200 mg/kg GPE（GPE200）、400 mg/kg GPE（GPE400）和600 mg/kg GPE（GPE600）的玉米-豆粕基础日粮。整个实验持续7周。
结果表明，日粮中添加600 mg/kg GPE可显著降低血清尿素氮、甘油三酯（TG）和总胆固醇（TC）含量。添加GPE（200、400和600 mg/kg）可有效降低IL-2和MDA含量。与对照组相比，GPE600组的免疫球蛋白M（IgM）水平和总抗氧化能力（T-AOC）显著升高。日粮中添加GPE可显著提高胸肌的水分含量。此外，日粮中添加GPE可显著降低失水率和剪切力。
随着家禽生产中抗生素的禁用，传统中药因其高效、低毒而被广泛应用于畜禽生产。 提取物GPE作为一种天然植物来源，含有一系列生物活性成分，包括黄酮类、多酚类、皂苷、单宁和萜类。本研究表明，日粮中添加GPE可提高肉鸭血清总抗氧化能力，调节免疫功能，在一定程度上改善肉质。根据本研究结果，肉鸭日粮中GPE的推荐最佳添加水平为600 mg/kg。
