Abstract :

Given the hazards of using chemical drugs in various areas of broiler breeding including drug resistance, high cost and many other side effects, the need for herbal medicines has increased in all animal health issues. Thymus with scientific name of Thymus vulgaris is a phytogenic compound. This plant has anti-bacterial and growth stimulator characteristics. Considering the widely use of phytogenic compounds as alternative to chemical drugs in human diet and livestock industry, this study tried to evaluate the impact of thymus extracts on growth performance, serum lipid profile and liver enzymes. In this regard a number of 240 one-day-chicks of Ross 308 broilers were housed in equal conditions. They were classified in two groups with three replicates (40 chicks per group). The experimental groups were as follows: control group, received maize-soybean diet; thymus group, received maize-soybean diet + thymus extract. The studied traits included feed intake, weight variation, Feed Conversion Ratio (FCR), serum lipid profile and liver enzymes. On 41st day, 25 chicks were selected randomly and their blood samples were obtained. The results showed that using thymus as feed additives improve weight gain and Feed Conversion Ratio (FCR) (p<0.05) and exert positive effect on lipid profile and liver enzymes compared to the control (p<0.05).
