Abstract

1. In recent years, tannin has been used as a natural alternative to antibiotics due to its wide availability, ease of large-scale production and efficient extraction from other plants, compared with foreign additives such as plant essential oils and organic acids.2. Tannins are secondary metabolites widely existing in plants as a natural defence mechanism, which exhibit various bioactivities. In poultry, appropriate addition of tannins can enhance the growth performance and play a positive regulatory role in intestinal health, but inclusion in diets is limited by the bitter taste of tannins. However, 1 g/kg tannin in feed significantly reduced the final body weight of broilers and disrupted normal morphology in the intestinal tract.3. Data indicated that the effect of tannin was significantly influenced by its source and dosage, but these differences need to be confirmed. However, there is data showing tannin regulation of intestinal health in poultry, providing practical ideas on mechanism of action and commercial applications.

单宁与家禽肠道健康的研究进展。

1. 近年来，与国外的植物精油和有机酸等添加剂相比，单宁因其可获得性广、易于大规模生产和从其他植物中提取效率高而被用作抗生素的天然替代品。单宁是广泛存在于植物体内的次生代谢产物，具有多种生物活性。在家禽中，适当添加单宁可以提高生长性能，对肠道健康有积极的调节作用，但单宁的苦味限制了其在饲粮中的添加。然而，饲料中添加1 g/kg单宁显著降低肉仔鸡最终体重，并破坏肠道正常形态。数据显示单宁的作用受其来源和剂量的显著影响，但这些差异有待证实。然而，有数据显示单宁对家禽肠道健康的调节，为作用机制和商业应用提供了实际的思路。

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 .
