摘要

The aim of the present study was to compare the growth promoter effect of 2 labiatae family herbal supplementation with antibiotic and probiotic on broiler chicks Performance. Seven hundred, 1 day-old broiler chicks were randomly divided into 5 treatment groups: Control, virginiamycin (0.1 g Kg 1), probiotic (1 and 0.4 g Kg 1), zataria multiflora (ZM) (15 g Kg 1) and ziziphora Clinopodioides (ZC) (15 g Kg 1). Each treatment group was further sub divided into 4 replicates of 35 birds per replicate. During experimental period, growth performance was evaluated by recording body weight, feed intake, Feed Conservation Ratio (FCR), mortality and Efficiency Productive Index (EPI) by the followed formula at 21 and 42 days. At 42 days, EPI differed significantly among treatments. The EPI of the treatment fed on the diet containing virginiamycin was the highest and those ZM was the lowest. Addition of ZC to broiler diet improved EPI, body weight compare with the control But this different was not significantly (p>0.05) but have similar effect to addition of probiotic (p>0.05). ZM had lower body weight and EPI and higher FCR compare with control and ZD groups (p>0.05). It was concluded that the supplementation of herbal additive to broiler diets had beneficial effect on their performance and 2 herbs from 1 family had different effects.
