USING OF DRIED BETONY AND PEPPERMINT IN BROILER DIETS ON PERFORMANCE, HEMATOLOGICAL AND IMMUNITY RESPONSE.

Abstract

This experiment was aimed to investigate the effect of using different levels of betony and peppermint alone or together on body performance, hematological traits and immunological response in Ross-308 broiler male chickens, in this experiment three hundred and sixty (360) day old sexed male chicks (Ross-380) were randomly divided into 12 replicates, 30 chicks per replicate (three replicates per treatment). The four treatments in this experiment are: T0=control (standard ration), T1 (2% dried betony), T2 (2% dried peppermint) and T3 (1% betony+ 1% peppermint). The effect of betony and peppermint added to broilers diet is presented showed significant increases (P<0.05) in body weight in T2 at 25 days, relative weight of heart, liver, gizzard, proventriculus and fabricius, also showed significant increases (P<0.01) in body weight at 42 days, body weight gain at 25 and 42 days in T1, T2 and T3 also in eviscerated dressing, the relative weight of (breast, thigh, drumstick, wings and spleen), but showed that FCR differ significantly (P<0.01) among treatments, better feed conversion was found in T1, T2 and T3 at ages 25 and 42 days. While, the results shows significant induces (P<0.01) in mortality and relative weight of (abdominal fat, neck and back), but there were no significant differences among the treatments with control in Feed consumption at ages 25 and 42 days. Thus the results showed significant increases (P<0.01) in total count of red blood cells (RBCs), hemoglobin (Hb), packed cell volume (PCV), total protein concentration and high density lipoprotein (HDL), While, the results shows significant induces (P<0.01) in H/L ratio, cholesterol concentration and low density lipoprotein (LDL) in T2, T3 and T1 as compared with T0, but there were no significant differences among the treatments with control in total count of white blood cells (WBCs). Also the results showed significant increases (P<0.01) in antibodies titer of Newcastle Disease (HI), Gumboro Disease (IBD) and Infectious Bronchitis Viral (IBV) in T1, T2 and T3. In all traits T2 achieved more improving as compared with the other treatment of this experiment.
