Effect of Rhus coriaria L. on performance productive, physiological and carcass characteristics of broiler chicks

Abstract

A study conducted to estimate effect of Rhus Coriaria L in performance productive, blood profile lipids, carcass characteristics and intestinal flora. A total of 135 chicks Ross308 that divided randomly for three treatments, each treatment divided to three replicates. T1 as control treatment (without supplementation), while T2, T3 received 1, 2 gm/kg diet from sumac powder respectively. The results showed significant superiority in body weight, weight gain and feed conversion in T2, T3 and significant decreased in feed intake in T2. The dressing percentage significantly increase T2, T3, also noted significant increase in breast weight in T3, drumstick weight and abdominal fat percentage in T2. As for the giblets the gizzard showed a significant increase in relative weight. The blood lipids showed significant decrease in TG, HDL, VLDL concentration in T2, T3. The microbiological study showed that number of E. Coli and clostridium significant decrease (P<0.05) in T3 and Staphylococcus decrease in T2, T3, conversely noted significant increase of lactic acid bacteria in T2, T3 compared to control. It can conclude from this study that sumac has a noticeable effect on the productive, physiological performance and intestinal flora of broilers.
