Abstract

Research highlights: Supplementation with CuNP in feed and water reduced Salmonella Enteritidis count.Supplementation with CuNP did not affect intestinal integrity of broilers.CuNP did not affect weight gain or total lactic acid bacterial counts.The results demonstrate the potential of CuNP as alternative antimicrobials.

纳米铜颗粒能有效减少肉鸡日粮和水中的肠炎沙门氏菌。

ABSTRACTThe use of copper nanoparticles (CuNP) in the diet of broiler chickens has been studied as a potential alternative to antibiotic growth promoters.本研究旨在分析 CuNP 在肉鸡饲料和饮水中对肠炎沙门氏菌的抗菌特性，并评估 CuNP 的肠道完整性和毒性。本研究旨在分析 CuNP 在肉鸡饲料和饮水中对肠炎沙门氏菌的抗菌特性，并评估在肉鸡日粮中添加 CuNP 的肠道完整性和毒性。CuNP 对肠炎沙门氏菌的抗菌活性在微孔板中进行了测试，以评估三种不同矿物质成分的水样，并在体外消化率模型中进行了测试，该模型模拟了禽类的三个主要肠道区，以评估饲料样品。为评估体内肠道完整性和毒性，将鸟类分为四组（每组 30 只）：(1) 基础日粮（对照组）；(2) 基础日粮 + CuNP（100 ppm）；(3) 基础日粮 + 恩拉霉素（10 ppm）；(4) 基础日粮 + CuNP（100 ppm）+ 恩拉霉素（10 ppm）。采集肠道样本进行组织形态计量学评估和乳酸菌计数，同时采集胸肌和全血样本测定铜含量。与对照组相比，在添加了 CuNP 的两种体外处理（水和饲料）中观察到肠炎球菌数量明显减少。与对照组相比，组织形态测量、增重或乳酸菌总数均无明显差异。这些结果表明，CuNP 能够有效减少肠炎双球菌的发生，而且不会干扰肉鸡肠道的完整性，从而凸显了 CuNP 作为家禽生产链中替代抗菌剂的潜力。

期刊介绍： Avian Pathology is the official journal of the World Veterinary Poultry Association and, since its first publication in 1972, has been a leading international journal for poultry disease scientists. It publishes material relevant to the entire field of infectious and non-infectious diseases of poultry and other birds. Accepted manuscripts will contribute novel data of interest to an international readership and will add significantly to knowledge and understanding of diseases, old or new. Subject areas include pathology, diagnosis, detection and characterisation of pathogens, infections of possible zoonotic importance, epidemiology, innate and immune responses, vaccines, gene sequences, genetics in relation to disease and physiological and biochemical changes in response to disease. First and subsequent reports of well-recognized diseases within a country are not acceptable unless they also include substantial new information about the disease or pathogen. Manuscripts on wild or pet birds should describe disease or pathogens in a significant number of birds, recognizing/suggesting serious potential impact on that species or that the disease or pathogen is of demonstrable relevance to poultry. Manuscripts on food-borne microorganisms acquired during or after processing, and those that catalogue the occurrence or properties of microorganisms, are unlikely to be considered for publication in the absence of data linking them to avian disease.
