Infectious bronchitis (IB) is one of the most common viral diseases of poultry. The objective of this study was to estimate the distribution of avian infectious bronchitis virus isolate in experimentally infected chicken. Twenty-one-day-old commercial broilers were divided randomly into two groups (fifty in the experimental and twenty in the control group). Chicks in the experimental group were inoculated intranasal with 106 ELD50/0.1 mL of the virus. The samples from different tissues were collected at day 0, 3, 5, 7, 10, 15 and 20 postinoculation. Chickens showed mild respiratory signs and depression. Viral RNA was detected in the kidney, lung and tracheas. The most important clinical signs and virus finding appeared on day 1 pi. Data showed that the number of infected chickens and viral RNA detection from tissues was reduced with increasing antibody titer on day 20 pi. The results demonstrated that the IB virus has wide tissue distribution for respiratory, urogenital, and digestive systems.

This study was conducted to determine the concentration of Cd, Pb and Zn (using Atomic Absorption Spectrophotometer ASS) in nine brands of chicken livers: (Keyf-i Gezzet, Al Murad, Al Kafeel, Sadia 2, Sadia 1, Karbala, Halal, Faqeeh, in addition to livers of locally breed chicken), which are widely consumed from the local markets of Basrah city. The levels of metals in the chicken livers were ranged between (0.004) μg/g and (0.124) μg/g for Cd; (0.171) μg/g and (3.269) μg/g for Pb; and (4.116) μg/g and (3.266) μg/g for Zn. The results showed that concentration of Pb in four brands exceeded the permissible limits set by WHO/FAO (1) and ANZFA (2). The concentrations of Cd and Zn in all samples were within the tolerance limits.

The present study aimed to determine some of reproductive values of water buffaloes in marshes of Iraq which may be used as a primary values for assaying the reproduction and production of water buffaloes. The study performed on immature male and female water buffaloes. Estradiol and progesterone hormones were determined. The results showed effect of sex on the levels of estradiol and progesterone of male and female buffaloes. The age was effective in estradiol and progesterone levels of female buffaloes, while it was no effective on estradiol and progesterone levesl of male water buffaloes.

This experiment was designed to elicit the effect of zinc on the hematological picture and the histological effect on heart, kidney and liver of the domestic ducks. The birds were divided into two groups of eight birds each. The first group was the control group and the second one was the treated group in which the birds were fed the zinc sulphate as 100 mg/kg with food for four weeks. The results showed a decrease in hemoglobin, MCV, MCH, and MCHC. And an increase in red blood cells blood cholesterol,GOT and GPT. Histologicaly, the results showed a hydropic degeneration in the myocardial and renal cells beside a fatty degeneration in the liver texture

Clinical sings ,hematology and some biochemical changes have been investigated in local breed drought horse affected with acute laminitis in Basrah-Iraq .The study were conducted on 55 local breed drought horse 2-10 years old and from both sexes, from these ,Forty local breed drought horses show sings of acute laminitis and 15 clinically healthy local breed drought horses served as control . Results showed that diseased animals exhibited different clinical sings include loss of appetite, pain on palpation around the coronet, abnormal standing position with shuffling gait during standing , increase pulse in the palmar digital artery, sweating and anxiety were more prominent, more over body temperature, respiratory and heart rate were also increased . The results indicated no significant increase in RBC count and Hb while the results indicated significant increase in PCV,ESR and fibrinogen in diseased horses affected with acute laminitis. The results also indicated a significant increase in WBC as a result of significant increase neutrophils . Biochemical changes revealed significant increase in AST, ALT,ALP and total bilirubin, however significant increase in cholesterol were also encountered in affected horses with acute laminitis .

This work was done to investigate the effect of replacing the yellow corn (maize) with sorghum (white corn) and soy bean with peas on body weight, food intake, some hematological (PCV. And Hb) and also on some biochemical parameters (protein and urea). 72 one day old unsexed broiler chicks of average body weight 40-45 gm; they were divided into 3 equal groups of 24 chicks with 3 replicates. The first group were fed a diet containing sorghum ; the second group were fed a diet containing peas while third group fed normal diet. All groups fed on a starter diet for the first 28 days and then fed on growth diet till 49 days of age. Results showed significant increase in food intake, body weight in all experimental groups. Also significant increase were obtained in hematological parameters increased (Hb and PCV)as well as in serum biochemical parameters studied (P

The present study was designed to investigate the cellular cytogenetic effect of lead poisoning and the therapeutic role of selenium and olive oil as an antioxidant in mouse bone marrow cells. Twenty one female mice, 12 weeks old, and of 20–25 gram weight were used. The female mice which divided into seven groups each group consist of 3 female mice ,the control group: oral giving by 0.9 % normal saline (N.S) daily for 28 days. The treated groups A,B,C,D,E,F: received orally with 50 mg/kg BW lead acetate, 50 mg/kg of lead acetates + o.5 mg/kg of selenium, 50 mg/kg of lead acetates +0.2 CC of olive oil, 100 mg/kg of lead acetates, 100 mg/kg of lead acetates+ o.5 mg/kg of selenium, 100 mg/kg of lead acetates+0.2 CC of olive oil daily for28 days respectively, The administration of different doses of lead acetate caused a significant increase (P

This study was carried out for detection of Salmonella isolates from 309 different apparently healthy samples (97 fecal, 71 bile, 102 intestinal content, 18 livers and 21 spleen) collected from slaughtered sheep in a slaughterhouse in Basra during the period between September to November 2010. The results revealed that the incidence rate of salmonella isolates in fecal samples was 7.2 %, in bile samples 8.5 % and in intestinal content 9.8%. While no isolations were obtained from the liver and spleen samples. The total positive sample of salmonella isolates was 23 (7.4%).

The present study had thrown the light on the in vitro antimicrobial potential of the ethanolic extract of three local medicinal plants; Coriandrum sativum (Coriander), Vitis vinifera (Grape seeds), and Zingiber officinale (Ginger) against the growth of pathogenic Staphylococcus aureus isolated from milk of some local cows infected with clinical mastitis. The antibacterial activity was carried out by using agar well diffusion technique in Mueller-Hinton agar. Four concentrations could be prepared from each plant extract, these concentrations were 50, 100, 200, and 400 mg/ml. The results were obtained by measured the zone of inhibition around the well that could be exhibited by each plant concentration that followed incubation of bacterial plates and expressed as mean±Standard error (SE). Ethanolic extract of Coriandrum sativum was possessed the strongest antibacterial effect among the tested plants, the results were: 29.44±1.17, 29.22±0.32, 27.77±0.99, and 26.11±1.27 mm at a concentration of 50, 100, 200, and 400 mg/ml respectively, Followed by Vitis vinifera extract which showed moderate values recorded as 20.88±0.77, 20.11±0.58, 18.22±0.36, and 20.88±0.35 mm at a concentration of 50, 100, 200, and 400 mg/ml respectively. The least antibacterial activity was exhibited by the extract of Zingiber officinale that produced the following inhibition zones; 15.11±0.80, 15.77±1.12, 17.66±0.33, and 17.55±0.44 mm at a concentration of 50, 100, 200, and 400 mg/ml respectively. On the other hand, S.aureus was variably susceptible to five of the used standard antibiotics; Lomefloxacin, Erythromycin, Amoxicillin, Ciprofloxacin, and Rifampin. Means of their inhibitory zones were; 29.44±0.41, 23.22±0.46, 21.77±0.36, 19.88±0.42, and 11.11±0.26 mm respectively. Whereas Cefprozil showed no effect against the growth of the tested organism.

In this study, three heavy metals (mercury, nickel and copper) in twenty eight canned fish and meat samples were determined by atomic absorption spectrophotometer. The metal contents, expressed in ppm (mg/ L), varied from 0.01 to 3 ppm in canned fish and from 0.001 to 2 ppm in canned meat for mercury, from 0.0001 to 0.0003 ppm in canned fish and from 0.0001 to 0.0007 ppm in canned meat for a nickel, and from 0.001 to 0.01 ppm in canned fish and from 0.001 to 0.1 ppm in canned meat for copper. The results of this study showed the concentration of mercury in fish and meat samples exceed normal levels, and statistical analysis of results by ANOVA showed significant differences between fish and meat in some samples for mercury
