摘要

本试验旨在研究当归水溶性提取物（WEAs）对鱼类生长性能和耐缺氧性能的短期影响。所有420鲤鱼(鲤科鲤鱼变种剑；6.64 ± 0.02 g)，分别饲喂7种含WEAs（0、0.7、1.4、2.8、5.6、11.2和22.4 %）的饲粮，饲喂15 d。由此可见，饲粮中添加适量WEAs可提高鲤鱼采食量和增重，提高消化器官中脂肪酶、γ-谷氨酰转移酶和碱性磷酸酶的活性。通过对增重和饲料效率的折线回归分析，得出鲤鱼的最佳WEAs添加量分别为1.476 %和1.478 %。适当添加WEAs可降低低氧条件下的耗氧量（OCR）和血浆氨、葡萄糖含量，提高缺氧持续时间（DT）、血浆总蛋白含量以及肌肉、鳃和肝胰脏中谷氨酸-丙酮酸转氨酶和谷氨酸-草酰乙酸转氨酶活性。经DT和OCR折线回归分析，鲤鱼的最佳WEAs添加量分别为2.610 %和2.605 %。此外，适当添加WEAs降低了丙二醛和过氧化氢含量，提高了鱼鳃、肌肉或消化器官中过氧化氢酶、抗超氧阴离子、超氧歧化酶、抗羟基自由基和谷胱甘肽过氧化物酶的活性，降低了谷胱甘肽含量。综上所述，饲粮中适当添加WEAs可提高建鲤的生长性能，这与消化器官的抗氧化能力和消化吸收功能密切相关，并可提高呼吸器官的抗氧化能力和蛋白质和碳水化合物代谢能力，从而提高缺氧耐受性。因此，WEAs可以作为鱼类缺氧应激的天然抑制剂。

Short-term effects of diets containing a water-soluble extract of Angelica sinensis on growth performance and hypoxia tolerance of juvenile Jian carp (Cyprinus carpio var. Jian)

This study investigated the short-term effects of water-soluble extract of Angelica sinensis (WEAs) on fish growth performance and hypoxia tolerance. All 420 carp (Cyprinus carpio var. Jian; 6.64 ± 0.02 g) were fed 7 diets containing WEAs (0, 0.7, 1.4, 2.8, 5.6, 11.2, and 22.4 %) for 15 days, respectively. The findings demonstrated that appropriate supplementation of WEAs increased feed intake and weight gain, as well as the activities of lipase, γ-glutamyl transferase, and alkaline phosphatase in digestive organs of carp. Based on broken-line regression analysis of weight gain and feed efficiency, the optimum WEAs supplementation for carp were 1.476 % and 1.478 %, respectively. Appropriate supplementation of WEAs decreased oxygen consumption rate (OCR) under hypoxia condition as well as plasma ammonia and glucose contents, increased hypoxia durative time (DT), plasma total protein contents, and glutamate-pyruvate transaminase and glutamate-oxaloacetate transaminase activities in carp's muscles, gills, or hepatopancreas. Based on DT and OCR broken-line regression analysis, the optimum WEAs supplementation for carp were 2.610 % and 2.605 %, respectively. Furthermore, appropriate supplementation of WEAs decreased malonaldehyde and hydrogen peroxide contents and increased the activities of catalase, anti-superoxide anion, superoxide dismutase, anti-hydroxyl radical, and glutathione peroxidase as well as reduced glutathione content in fish gills, muscles, or digestive organs. Overall, our current study suggests that dietary appropriate supplementation of WEAs improved growth performance that closely related to the antioxidant capacity as well as the digestive and absorption functions in the digestive organs, and enhanced hypoxia tolerance that attributed to the antioxidant capacity and metabolism of proteins and carbohydrates in the respiratory organs of Jian carp. Therefore, WEAs can serve as a natural inhibitor of hypoxic stress in fish.

期刊介绍： Animal Feed Science and Technology is a unique journal publishing scientific papers of international interest focusing on animal feeds and their feeding. Papers describing research on feed for ruminants and non-ruminants, including poultry, horses, companion animals and aquatic animals, are welcome. The journal covers the following areas: Nutritive value of feeds (e.g., assessment, improvement) Methods of conserving and processing feeds that affect their nutritional value Agronomic and climatic factors influencing the nutritive value of feeds Utilization of feeds and the improvement of such Metabolic, production, reproduction and health responses, as well as potential environmental impacts, of diet inputs and feed technologies (e.g., feeds, feed additives, feed components, mycotoxins) Mathematical models relating directly to animal-feed interactions Analytical and experimental methods for feed evaluation Environmental impacts of feed technologies in animal production.
