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