Effect of Mentha piperita powder and Citrus aurantium extract on heat shock protein (HSP70) gene expression and some blood parameters of broilers chickens in heat stress condition

The application of medicinal herbs has a meaningful importance in human health because of their compounds have the minimal side effects on human body. This study was conducted to evaluate the effects of peppermint powdered extract, orange flower extract and neomycin on Heat Shock Protein (HSP70) gene expression and some blood parameters of broilers chickens under heat stress conditions.
In this study, 120 one – day old Ross 308 broiler chicks have been used. The research has been performed during 6 weeks in a completely randomized design (CRD) with and 4 treatments 3 replicates and 10 chicks per each replicate. The experimental treatments include: control treatment, peppermint powdered extract )2 % of feed(, orange blossom extract ) 2% of the consumed water( and neomycin antibiotic (0.2 g/kg of feed). The relative gene expression of heat shock protein 70 )HSP70( and some blood parameters have been examined in the blood.
The highest concentration of triglyceride was observed in orange blossom extract treatment (P The findings of this research suggested that the medicinal herbs namely peppermint and orange blossom extract are capable to control the negative effect of heat stress on chicken performance.
