The objective of this study was primarily to assess the different performance impacts of two ionophore coccidiostats (narasin and salinomycin) used to manage coccidiosis. While both products may be efficacious in controlling disease challenges, previous literature has suggested that some ionophores are less well tolerated by the broiler chickens. In this study, we were particularly interested to know how the use of different coccidiostat programs translates into broiler health and performance, as measured by zootechnical parameters such as the feed conversion ratio, average daily gain, and final body weight. A total of 352 male Ross 308 one-day-old broilers were randomly divided into two treatment groups (T1 and T2). Treatment 1 included a basal diet (BD) + nicarbazin/narasin (Maxiban, Elanco) at 100 ppm 0-24 days, narasin at 70 ppm 25-42 days, and (2) Treatment 2 included basal diet + nicarbazin/narasin at 100 ppm 0-24 days, salinomycin (Sacox, Huvepharma) at 70 ppm 25-42 days. Efficacy and performance parameters, slaughter analysis, dry matter (DM) in litter, and intestinal integrity (I) were measured for the broilers from both treatment groups. The findings demonstrated more favorable results for broilers reared in the group diet fed with narasin (in the finisher phase), including higher daily body weight gain, higher final body weight, lower feed conversion ratio value (improved feed efficiency), and higher European Production Efficiency Factor value, compared with the salinomycin-supplemented group.
本研究的主要目的是评估两种用于防治球虫病的离子载体抗球虫药（那拉菌素和盐霉素）的不同性能影响。虽然这两种产品在控制疾病挑战方面可能都有效，但先前的文献表明，一些离子载体对肉鸡的耐受性较差。在本研究中，我们特别想了解不同抗球虫药方案的使用如何转化为肉鸡的健康和性能，这通过饲料转化率、平均日增重和最终体重等畜牧学参数来衡量。总共352只1日龄的罗斯308雄性肉鸡被随机分为两个处理组（T1和T2）。处理1包括基础日粮（BD）+ 100 ppm的尼卡巴嗪/那拉菌素（Maxiban，英特威），0至24天使用，25至42天使用70 ppm的那拉菌素；（2）处理2包括基础日粮 + 100 ppm的尼卡巴嗪/那拉菌素，0至24天使用，25至42天使用70 ppm的盐霉素（Sacox，赫维药业）。对两个处理组的肉鸡测量了疗效和性能参数、屠宰分析、垫料中的干物质（DM）以及肠道完整性（I）。研究结果表明，与添加盐霉素的组相比，在育肥期饲喂那拉菌素的日粮组饲养的肉鸡有更有利的结果，包括更高的日体重增加、更高的最终体重、更低的饲料转化率值（提高了饲料效率）以及更高的欧洲生产效率因子值。
