Effect of Tylvalosin on Blood Parameters in Healthy Broiler Chickens

To evaluate the effects of Tylvalosin on blood parameters in healthy broiler chickens, twenty broiler chicks (Ross 308) aged 21 days old and weight 600-800 gm was divided into two equal groups, the first one was control group (G1) and the second one was treated group (G2). G1 dosed with 1ml/kg of body weight of normal saline while G2 dosed with 25mg/Kg of body weight of Tylvalosin. Blood samples were collected with EDTA tubes after 4 days of treatment. The results showed significant decrease in total WBCs counts in G2 treated group as compared with control group (G1), also the eosinophil showed a significant decrease in G2 as compared with G1, while other parameters didn’t show any significant differences. In conclusion, WBCs were decreased after treatment with tylvalosin.
