Abstract

This study aimed to detect how supplementing olive leaves extract (OLE) and olive pomace extract (OPE) to growing rabbit diets has affected productive performance, nutrient digestibility, carcass characteristics, antioxidant status, and economic efficiency. At 42 days of age, 75 APRI growing rabbits were separated into five groups, 15 rabbits each. Control (without additives), OLE1 (200ppm of OLE), OLE2 (400ppm of OLE), OPE1 (200ppm of OPE), and OPE2 (400ppm of OPE) were the experimental diets. Throughout the trial, we computed feed consumption and increase in body weight on a weekly basis. Compared to the control group, the body weight, weight gain, and feed conversion ratio of rabbits fed OLE or OPE were significantly (P<0.05). The digestibility coefficient of crude protein-enhanced significantly (P<0.05) in rabbits fed OLE or OPE than in control rabbits. In addition to using OLE or OPE, the percentage of the carcass was improved dramatically (P<0.05). Total antioxidant capacity, Superoxide dismutase, and catalase levels were significantly (P<0.05) raised with OLE or OPE, while malondialdehyde levels were lowered. In conclusion, supplementing rabbit diets with 200 or 400ppm of OLE or OPE enhanced productive performance and antioxidant status without any negative effect on their health.

生长兔日粮中橄榄叶和果脯提取物对生产性能、养分消化率、胴体特性、抗氧化状况和经济效益的评价

本试验旨在研究在生长兔日粮中添加橄榄叶提取物(OLE)和橄榄渣提取物(OPE)对生产性能、营养物质消化率、胴体特性、抗氧化状态和经济效益的影响。42日龄时，将75只APRI生长兔分为5组，每组15只。对照饲粮(不含添加剂)、OLE1 (OLE含量为200ppm)、OLE2 (OLE含量为400ppm)、OPE1 (OPE含量为200ppm)和OPE2 (OPE含量为400ppm)为试验饲粮。在整个试验期间，我们以每周为单位计算采食量和体重增加。与对照组相比，OLE组和OPE组的体重、增重和饲料系数显著提高(P<0.05)。与对照组相比，OLE和OPE组粗蛋白质消化系数显著提高(P<0.05)。除使用OLE或OPE外，屠体率显著提高(P<0.05)。OLE和OPE显著提高了总抗氧化能力、超氧化物歧化酶和过氧化氢酶水平(P<0.05)，降低了丙二醛水平。综上所述，饲粮中添加200或400ppm的OLE或OPE可提高家兔的生产性能和抗氧化能力，且对健康无负面影响。

期刊介绍： “International Journal of Veterinary Science” (IJVS) is an online international peer reviewed open access journal which publishes original research papers. Its scope is broad and international, covering a wide range of research areas including: anatomy, biochemistry, biotechnology, clinical medicine and surgery, Theriogenology, physiology, pharmacology, pathology, microbiology and immunology, parasitology, epidemiology, breeding and genetic, feed and nutrition, wild life, animal products and their processing. Original research papers, review articles, extension articles, clinical articles and short communications on the production and diseases of animals, including studies in comparative medicine is published in this journal. Only those manuscripts are considered for publication, the contents of which have not been published and are not being considered for publication in any other journal.
