摘要

这项研究是在厄瓜多尔埃尔奥罗省马查拉大学农业科学学院的Santa insamacs农场进行的。目的是评价羊草对科布500肉鸡生产和经济参数的影响。为了鸟类的健康,在该地区建立了开放式房屋系统的管理。试验采用完全随机设计,共6个处理,每个处理4个实验单元,每组10只鸡,共评估240只鸡。处理安排为:T1或对照,以商品型基础饲粮为基础,在T2、T3、T4和T5处理的平衡饲粮中分别添加0.25、0.50、0.75和1.00%的脱水磨碎叶片,替代生长促进剂抗生素(GPA);T6或空白,不含GPA和脱水的amboinicus平衡混合物。评价变量为活增重(LWG)、饲料消耗量(FC)、累积耗水量(AWC)、饲料系数(FCR)、死亡率(M)、生产效率因子(PEF)、每m2活肉kg、经济费用和每kg活肉成本。对于所有变量,使用方差分析,先前的正态性和均匀性假设,并使用Tukey's诚实显著差异(HSD)程序来区分平均值,置信水平为95%。所有数据均采用SAS统计软件包中的PROC GLM(一般线性模型)程序进行分析。结果表明,oreganón可作为肉仔鸡GPA的替代品,且不影响生产和经济参数。

Use of Plectranthus amboinicus in chickens and its effect on productive and economic parameters
This research was carried out at the Santa Inés Farm of the Faculty of Agricultural Sciences of the Universidad Técnica de Machala, El Oro Province, Ecuador. The aim was to evaluate the effect of Plectranthus amboinicus, commonly called oreganon, on the productive and economic parameters of Cobb 500 broilers. For the well–being of the birds, the management established for open house systems in the area was used. A Completely randomized design was applied, where 6 treatments were used, each with 4 Experimental Units of 10 birds, for a total of 240 chickens evaluated. The treatments arrangement was: T1 or control which was based on a commercial type basal diet, while, to the balanced diets of treatments T2, T3, T4 and T5, the dehydrated–ground leaf of P. amboinicus was added at 0.25, 0.50, 0.75 and 1.00%, respectively, in replacement of the Growth Promoter Antibiotic (GPA); the T6 or blank, which did not contain GPA and dehydrated P. amboinicus in the balanced mixture. The variables evaluated were live weight gain (LWG), feed consumption (FC), accumulated water consumption (AWC), feed conversion ratio (FCR), mortality (M), productive efficiency factor (PEF), kg of standing meat per m2, economic expenses and cost per kg of standing meat. For all the variables, an ANOVA was used, previous assumptions of normality and homogeneity, and to discriminate between the means, Tukey's honest significant difference (HSD) procedure was used, with a confidence level of 95%. All data were analyzed using the PROC GLM (General Linear Model) procedure of the SAS statistical package. The results showed that oreganón could works as a replacement alternative to the GPA in broilers, without harming the productive and economic parameters.
