Introduction: Zattariamultiflora (Z. multiflora) is a herb belonging to Labiatae family with known therapeutic effects, like anti-inflammatory and antimicrobial activity especially for gastrointestinal tract and respiratory systems and use of such herbs seems to be necessary in today’s medicine. The aim of present study was to evaluate the effects of Z. multiflora essence on immunity of broilers. Materials and Methods: Different concentrations of Z. multiflora were added to the food of broilers, then the antibody titer’s were measured for Sheep Blood Cells (SRBC) and Newcastle Disease virus (NDV) plus stimulation rate of T-lymphocytes by Delayed-Typed Hypersensitivity (DTH) assay Results: Assays revealed that addition of 200 & 400 ppm of Z. multiflora essence in the diet of broilers increased Ab levels against NDV, statistically (p

The aim of this study was to evaluate the influence of age and sex on the concentration of total serum protein measured by the biuret method and protein fractions determined using cellulose acetate electrophoresis in apparently healthy camels (Camelus dromedarius). Blood samples were collected from 21 camels (12 males and 9 females). The camels were further divided into two groups: 12 young camels at the age of 3 months to 2 years and 9 adult camels at the age of 3-15 years. Cellulose acetate electrophoresis of serum proteins identified five protein fractions in adult camels as young camels, these five protein fractions include albumin, α1 and α2, β and γ-globulins. In adult camels, serum levels (g/l) of total protein, albumin, α1-globulins, α2-globulins, β-globulins and γ-globulins were 80.9±3.10, 42.9±3.10, 1.3±0.22, 2.2±0.30, 11.8±0.30 and 22.6±0.20, respectively. However, in young camels, these levels (g/l) were 66.8±2.90, 40.2±2.40, 1.0±0.14, 2.6±0.30, 10.6±0.80 and 12.3±1.20, respectively. The albumin/globulin (A/G) ratio was 2.08±0.28 in adult camels and 3.77±0.53 in young ones. The mean serum concentrations of total protein and γ-globulins were significantly (P
