A study was conducted to determine the effect of three native plants from El-Jabal al ELAkhdar, (Libya) on performance and cecal coliform count of broiler chickens. A total of 1260 one-day-old male Cobb chickens were used in the experiment. The birds were assigned to 7 treatment groups (6 replicates per treatment). The dietary treatments included basal diet with no additive (control), and 6 other dietary treatments (Arbutus pavarii, Salvia officinalis and Zizyphus Vulgaris) each of which was added at the rate of 0.5 g and 1 g/kg of basal diet. Results explicitly revealed that all dietary treatments had a significant effect on body performance of broiler chickens compared to the control with the exception of the dietary treatment of S. officinalis at dosage of 0.5 g/kg that has expressed noticeable reduction in body weight. Coliform counts in the cecum of birds receiving 1% A. pavarii and 1% Z. Vulgaris were significantly lower (P ⩽ 0.05) than those of control group from early weeks of treatments, whereas all plant shows a significant lowering (P ⩽ 0.05) of cecal coliform count during the rest of experiment compared to control group. These results emphasize the potential biotic role of such plants together with the immune modulating effects on treated birds. However, further pharmacological and clinical work should be adopted in the future to present an obvious understandable theory behind the potential beneficial as well as side effects of such natural plants.

A study was conducted to determine the effect of three native plants from El-Jabal al ELAkhdar, (Libya) on hematological profile, cholesterol and immune response to ND vaccine in broiler chickens. A total of 1260 one-day-old male Cobb chickens were used in the experiment. Chickens were assigned to 7 treatment groups (6 replicates per treatment). The dietary treatments included basal diet with no additives (control), and 6 other dietary treatments (Arbutus pavarii, Salvia officinalis and Zizyphus Vulgaris) each of which was added at the rate of 0.5g and 1g/kg of basal diet. Results explicitly revealed that no significant change in TLC between the treated and control groups has been recorded. A significant heteropenia was recorded at the third week of treatment with 1% A. Pavarii 0.5 S. Officinalis and 0.5 Z. Vulgaris when compared to control group. However, the lymphocytic count show a significant increase (P≤0.05) in all treated groups compared to the control groups. Immunologically, an enhanced humeral immune response was very obvious based upon the significant elevation of antibody titer at the third week of treatment for all groups received 1 % of the three types of plants. Interestingly , cholesterol levels were significantly elevated at the six week of treatment with 0.5 % Z. Vulgaris while highest decline in cholesterol levels were recorded in group that have received 0.5 S. Officinalis.

Introduction: A total of 32 young (1-3 months-old) lambs suffered from mortal neurological signs in a period of three months. The lambs were among the offspring of a herd of 300 sheep, in Tarhouna city, Libya. The affected lambs were initially treated with antibiotics, multivitamins and mineral supplements, however, none of these treatments attenuated the death toll among the small lambs. Methods: Three lamb carcasses were submitted to the National Center for Animal Health (NCAH) for post mortem examination. Gross pathological examination of the brains detected hydatid cysts and yellowish lesions within the cerebral cortex. Results: The histopathologic examination of the brain showed the presence of inflammatory lesions and necrotic features surrounded by granulomatous inflammatory patterns, which are accompanied by a few parasitic cysts. Ordinary and modified Ziehl-Neelsen stains for bacterial infection were performed, but the results did not strongly indicate bacterial infection. Toxoplasmosis, particularly T. gondii, and Neospora were first suspected. Immunohistochemistry testing for T. gondii did not show any conclusive indication for the presence of this pathogen. However, meticulous microscopic examination (100x) of the histopathologic features and the patterns of host-pathogen interaction of toxoplasmosis indicate that these lambs may have suffered from necrotic encephalitis associated with a different type of toxoplasmosis.
