The effect of thyme powder on immune parameters in male lambs Farahani

In order to investigate the effects of thyme powder on the immune parameters, 20 lambs were allocated in 4 experimental groups at Research Station of Animal Science, University of Arak (Iran). The lambs were selected according to their ages and divided into 4 groups of 5 animals including i) a control group (group 1) aged 5.5 months on average and non-threated with the thyme powder ii) a thyme-threated group (group 2) of 5.5 months on average receiving 20 g/d of thyme powder iii) a control group (group 3) aged one year old on average without receiving the thyme powder treatment and iv) a thyme-threated-group of the average one-year old receiving 20 g/d of thyme powder. The experiment lasted 70 days. The results showed that the use of the thyme powder did not have significant effect on hematologic parameters, serum immunoglobulin concentrations (IgA, IgE, and IgM) in Farahani male lambs (p> 0.05) . The results of this study indicated that the use of thyme had no effect on blood parameters.
