Abstract

The present study was conducted to investigate the effects of borage extract (BE) on growth performance and the immune system of broilers at high-stocking-density. A total of 330 male Ross 308 broilers were distributed in a completely randomized design with six experimental treatments each with three replications. Treatments were T1: 10 broilers/m2 (positive control group), T2: 20 broilers/m2 (negative control group), T3: 20 broilers/m2 + 150 mg/l of borage extract (BE), T4: 20 broilers/m2 + 300 mg/l of BE, T5: 20 broilers/m2 + 450 mg/l of BE, and T6: 20 broilers/m2 + 600 mg/l of BE. Weight gain, feed intake, and feed conversion ratio (FCR) were measured weekly and immune responce were examined twice. The use of BE could improve weight gain, feed intake, and FCR in broilers reared at a high-stocking-density. BE treatment improved the immune response of broilers. According to the results, the use of BE at 600 mg/l is useful in reducing the effects of density stress. Therefore, BE can be used as a nutritional strategy to improve the bird performance in stressful conditions.

琉璃苣（Borago officinalis）提取物对高密度条件下肉鸡生长性能和免疫系统的影响

本研究旨在探讨琉璃苣提取物（BE）对高饲养密度下肉鸡生长性能和免疫系统的影响。总共 330 只雄性罗斯 308 肉鸡被分配在一个完全随机设计的六个试验处理中，每个处理有三次重复。处理为：T1：10只/平方米（阳性对照组）；T2：20只/平方米（阴性对照组）；T3：20只/平方米+150毫克/升琉璃苣提取物（BE）；T4：20只/平方米+300毫克/升BE；T5：20只/平方米+450毫克/升BE；T6：20只/平方米+600毫克/升BE。每周测定增重、采食量和饲料转化率（FCR），并两次检测免疫反应。使用 BE 可提高高饲养密度下肉鸡的增重、采食量和饲料转化率。BE能改善肉鸡的免疫反应。结果表明，使用 600 毫克/升的 BE 有助于降低密度应激的影响。因此，BE 可作为一种营养策略，用于提高肉鸡在应激条件下的生产性能。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
