Abstract

In order to evaluate the effects of Thymbra spicata and Echinacea purpurea powders on quality of thigh muscle in broiler chickens orally challenged with Campylobacter jejuni, a total of 192 one day old broiler chickens (Ross 308) were randomly assigned to six dietary treatments in a completely randomized design with four replicates of eight birds for 42 days of age. The experimental dietary treatments included: 1) basal diet without additive (control group); 2, 3) basal diet supplemented with Thymbra spicata powder (2. 5 and 5 g/kg); 4, 5) basal diet supplemented with Echinacea purpurea powder (2. 5 and 5 g/kg) and 6) basal diet supplemented with Erythromycin (0. 275 g/kg). All of the chicks were oral-gavaged with Campylobacter jejuni (4×1011 cfu/mL, one mL per bird) on d 21. In the finisher and entire periods, broiler chickens fed Echinacea purpurea (2. 5 g/kg), Echinacea purpurea (5 g/kg), and Thymbra spicata (2. 5 g/kg) had a higher feed efficiency than those on control diet (P<0. 05). Moreover, feeding broiler chickens on diets supplemented with Echinacea purpurea (5 g/kg) and Thymbra spicata (2. 5 g/kg) caused a decrease in Malondialdehyde concentration of thigh muscle (P<0. 05). Furthermore, broiler chickens fed diet containing Thymbra spicata (5 g/kg) had higher press loss (41/2%) and lower crude protein (22. 7%) in thigh muscle (P<0. 05). According to current results, Echinacea purpurea and Thymbra spicata powders at level of 2. 5 g/kg could be recommended because of improving Performance and reducing Malondialdehyde.
