Effects of virginiamycin and galbanum (Ferula gummosa boiss) on performance, carcass traits, immune system and blood parameters of broiler chickens

Background: Some medicinal plants can stimulate growth in poultry. Objective: To compare the effects of dietary addition virginiamycin antibiotic and galbanum plant (Ferula gummosa) on performance, carcass characteristics, immune system, blood factors broiler chickens. Methods: A total 250 one-day-old male Ross 308 chickens were randomly assigned to five treatments with replicates (10 birds per replicate). The were: control (basal diet), diet plus 0.1 g virginiamycin/kg diet) or one three levels powder (2.5, 5, 10 galbanum/kg diet). Results: Body weight gain, feed intake conversion ratio improved groups containing compared other (p<0.05). percentage liver, heart abdominal fat decreased 5 Spleen antibody titers against Newcastle disease SRBC significantly increased treatment resulted a significant decrease serum cholesterol, triacylglycerol, LDL Additionally, protein, albumin, globulin, HDL Conclusion: Galbanum improves performance system chickens, has similar promoting as virginiamycin.
