Abstract

This study aimed to investigate the comparison of effect of anticoccidal drugs including lasalocid and diclazuril with probiotic and synbiotic on the growth performance and intestinal morphology in broiler chicken. One hundred eighty chickens (Ross 308, 1 day old) were randomly divided into 6 equal groups (n=30) including the negative control (basal diet), the positive control (basal diet+oral inoculation of 3×104 sporulated oocytes of E. tenella, and four treatment groups. At days of 28 and 49 of age, 9 chickens were blindly chosen from each group were scarified by decapitation and their various segments of small intestine including ileum, jejunum, and duodenum were evaluated histomorphologically. We found that the economic losses resulted from coccidial infection in the poultry industry are caused by the decreased performance of broiler chicken induced by morphological changes in the any three segments specially jejunum. The anticoccidial drugs, synbiotic and probiotic can partially prevent morphological changes in any three segments of small intestine in broiler chicken with coccidiosis. Since morphological changes in the jejunum begin earlier than in other parts and surface area of jejunal villi is important for nutrition absorbance as well as growth performance, lasolacid was found to a be more efficient treatment in this regard.

比较拉沙乐胺、地克珠利、益生菌和共生菌对天牛小肠组织形态变化的影响

本研究旨在比较抗球虫药物（包括拉沙乐胺和地克珠利）与益生菌和合成益生菌对肉鸡生长性能和肠道形态的影响。将 180 只鸡（Ross 308，1 日龄）随机分为 6 个等量组（n=30），包括阴性对照组（基础日粮）、阳性对照组（基础日粮+口服 3×104 天鹅肠杆菌孢子卵母细胞）和 4 个治疗组。在 28 日龄和 49 日龄时，从每组中盲选 9 只鸡，断头后对其小肠的各个部分（包括回肠、空肠和十二指肠）进行组织形态学评估。我们发现，在家禽业中，球虫感染造成的经济损失是由于空肠等三个部分的形态变化导致肉鸡生产性能下降。抗球虫药物、合生素和益生菌可部分防止球虫病肉鸡小肠任何三个部分的形态变化。由于空肠的形态变化比其他部位开始得早，而且空肠绒毛的表面积对营养吸收和生长性能都很重要，因此拉索拉西在这方面的治疗效果更好。

期刊介绍： The journal was created as the Croce Azzurra in 1950. A quarterly peer-reviewed journal devoted to veterinary public health and other aspects of veterinary science and medicine, Veterinaria Italiana is published by the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise ‘G. Caporale’ (Istituto Zooprofilattico Sperimentale dell''Abruzzo e del Molise) in Teramo, Italy. The goal of the journal is to provide an international platform for veterinary public health information from Italy and other countries, particularly those in Eastern Europe and Africa, Asia and South America. Veterinarians and veterinary public health specialists are encouraged to share their knowledge and experience on this platform.
