BACKGROUND: Phytogenic products are considered as nonantibiotic feed additive which may exert their possible appreciate effects on poultry performance and health through stimulated digestive secretions. OBJECTIVES: This study was conducted to examine the effect of dietary Satureja khuzistanica powder (SKP) on pH of intestine contents, bile secretion and composition, and liver as well as blood lipids in Isfahan native breeder cocks. METHODS: Thirty-six 40-wk-old Isfahan native breeder cocks were individually caged and randomly allotted to three groups of 12 birds each and fed with diets containing 0 (control), 20 or 40 g/kg SKP for 10 weeks. At the end of experimental period all birds were killed and used for data collection on dry weight and pH of intestine segments, liver, bile and blood variables. RESULTS: Mean pH value in ceca contents was lower in the birds received diets containing 40 g/kg SKP compared with control cocks (P>0.05). Addition of SKP in diet at 20 g/kg significantly decreased liver lipids compared with the birds fed on control diet and the diet containing 40 g/ kg (P<0.05). Liver score based on external appraisal of the organ was improved in the cocks fed with SKP-supplemented diets compared with control birds (P <0.05). CONCLUSIONS: It was concluded that supplementation of diet with SKP could improve liver health and function in breeder cocks through reduced total lipids accumulation in liver. However, SKP does not exert cholinergic effect in cocks.
