摘要

球虫病是家禽业面临的主要挑战，通常导致生产性能下降、肠道损伤和死亡率增加。本试验研究了以菊粉、β-葡聚糖、维生素C、牛至油和肉桂油为主要成分的植物性和益生元添加剂组合（PPB）对艾美耳虫肉鸡的饲粮添加效果。选取288只罗斯308肉鸡，随机分为4个处理组（6个重复/组）：NEG组为阴性对照（基础饲粮），INF组为14日龄艾美耳虫处理组（基础饲粮），PPB组：艾美耳球虫攻毒（基础饲粮，添加PPB）；艾美耳球虫攻毒（基础饲粮，添加盐霉素）。评估肉鸡生产性能、卵囊脱落、病变评分、组织形态学、claudin-3表达和肠道淋巴细胞浸润。攻毒影响了体重（BW）、平均日增重（ADWG）和饲料系数（FCR），其中INF组的性能显著低于NEG组和添加组（p≤0.05）。在所有时间点，INF组的每克卵囊（OPG）计数均显著高于PPB和SAL组（p≤0.05），而抗球虫指数（ACI）和宏观病变总评分（TMLS）证实了两种干预措施的保护作用。组织病理学检查显示，感染引起肠段明显的上皮损伤。免疫组化分析显示，INF鸡十二指肠和回肠中Claudin-3表达升高（p≤0.05）。由此可见，饲粮中添加PPB对肉鸡艾美耳虫感染具有与盐霉素相当的保护作用。研究重点PPB有效地减轻了肉仔鸡的艾美耳虫感染。PPB和盐碱霉素均能减少卵囊排出量，以INF组卵囊排出量最高，pppb与盐碱霉素效果相当。

Investigation of dietary eubiotic supplementation on the growth performance and gut health parameters in broiler chicks challenged with Eimeria spp.: a pilot study.

Research highlights: Dietary supplementation with phytogenic and prebiotic blend (PPB) effectively mitigated Eimeria spp. infection in broilers.PPB and salinomycin reduced oocyst excretion.Oocyst excretion was highest in the infected group.PPB was as effective as salinomycin.

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.
