| The aim of the present study was to investigate the effect of dietary supplementation of thyme, sage and rosemary oil on performance of laying hens, cholesterol and some proteins ratio of egg yolk and Escherichia coli (E. coli) count in feces. Sixty four Lohman LSL laying hens with 24 weeks of age were randomly and equally assigned to four groups (n = 16). Each treatment consisted of 4 replications of 4 hens. The control group received a basal diet. In addition to the basal diet, the three experimental diets included one of the following supplements: 200 mg/kg thyme oil, 200 mg/kg sage oil, 200 mg/kg rosemary oil. Feed conversion of animals was improved by supplementation of thyme, sage and rosemary oil. Birds that were fed the 200 mg /kg thyme oil and 200 mg/kg rosemary oil diets, exhibited the largest egg weight in this study. The addition of sage oil to the laying hens feed led to a significant increase in the Haugh unit of the egg. It was also determined that E. coli concentration of feces samples was reduced significantly (P < 0.05) with usage of thyme oil and rosemary oil in laying hens diets. Thyme oil and rosemary oil exhibited a higher antimicrobial activity than sage oil. Results showed that there were no significant (P < 0.05) differences in the ratio of triglyceride and cholesterol of egg yolk among the dietary treatments. © Verlag Eugen Ulmer. |
