One hundred broiler chicks were divided into two groups A and B. The chicks in group A were control group and group B was challenged with field originated chicken infectious anemia virus (CIAV) at 7th day of age. The samples were collected on 7th, 14th, 21st, 28th and 35th day of post infection for hematological, biochemical, immunohistochemical and histopathological examination. The hematological analysis showed significantly (P Less than 0.05) low level of hemoglobin, decreased packed cell volume, leukocytopenia and thrombocytopenia in infected group as compared to control group. In immunohistochemical assay, CIAV was detected in portal zone of liver, epicardium and myocardium, lymphoid follicles of bursa of Fabricius, thymic lobules and mainly white pulp of spleen. Histopathological changes were observed in both lymphoid and non-lymphoid organs. Concerning the serum biochemical profile, hypoproteinemia, hypoalbuminemia, increased concentration of liver enzymes, creatinine and urea were observed in infected birds. Our results showed that field originated stra in is pathogenic for broilers which induce significant changes in hematology, serum biochemical profile and histopathology of lymphoid and non-lymphoid organs.

This study was designed to evaluate the effect of ginger (Zingiber officinale, Rosc.) essential oil on growth performance, serum biochemical profile, oxidative stress, and histological structure of testes and fertility traits in Japanese quail (Coturnix coturnix japonica). 96 three-week-old male Japanese quail weighing between 120 and 130 g were randomly assigned to 4 dietary treatment groups in a completely randomized design. Each group was divided into 4 replicates of 6 quails. Quails in control group received orally 100 μl/kg bw of distilled water, while the three test groups received, respectively, by gastric intubation 50, 100, and 150 μl/kg bw of ginger essential oil. At 12 weeks old, twelve birds per treatment were randomly selected and fasted for 24 hours, weighed, and slaughtered to assess organ and biochemical parameters. At the same period, 4 mature male quails per treatment were chosen at random and individually housed in cages, each with four untreated females for fertility and hatchability traits. The main results revealed that growth characteristics were not markedly (P>0.05) affected by essential oil whatever the dose. The left testis weight increased significantly (P<0.05) with 100 and 150 μl/kg bw of essential oil compared to the control. The serum content in total cholesterol and triglycerides, the liver weight, the serum content in transaminases, and malondialdehyde decreased in treated quails. The serum content in total protein and globulin and the antioxidant enzymes activities increased in treated birds compared to the control. The histological changes in the testis were less visible in treated Japanese quails. At the doses of 100 and 150 μl/kg bw, this essential oil induced a significant increase (P<0.05) in fertility rate compared to the control. Under the conditions of this study, the ginger rhizomes essential oil can be used in poultry to reduce the lipid peroxidation in reproductive tissues and improve the fertility traits.
