Myrtus communis(myrtle) is rare medicine plant that exist in limited areas in Iran and theworld. Essential oil of myrtle leaf is containing terpinolene, cineole,linalool,terpineol andlinalyl acetate. This experiment was conducted to evaluate the effect of myrtus communis leafon some blood parameters of Arabi sheep. Eight sheep with 9month’s age and average weight32±1.5 kg were fed with control diet (30:70 forage to concentrate without myrtle leaf) anddiet containing 4% myrtle leaf for one month. In the end of experiment, blood samples weretaken and some metabolites were measured. The results of this experiment showed dietcontaining 4% myrtle leaf significantly reduced blood urea, triglyceride and glucose ofsheeps in compared with the control diet. But the blood cholesterol value of sheeps did notaffected by inclusion of myrtle leave. Therefore, according to the effect of phytochemicals ofmyrtus communis leaf on decreasing blood parameters, it seems to be used by 4% in Arabisheep diet.

Investigation of bovine adenovirus type 3 in symptomatic and asymptomaticcattle were carried out in this study ofdetecting circulating specific bovine adenovirustype 3 antibodies by Indirect ELISA and standard PCR technique. The studyexhibited these virus have detected by ELISA more than PCR technique. The resultswere showed thatthe overall seropositivity ratio of bovine adenovirus antibodies inanimals of Basra was (61.9%) and bovine fecal samples will tested byPCRwereonly seven fecal positive sample (6.1%) was found.

The present study was conducted during the period from September 2015 untilApril 2016. 100 fecal samples was collected from goats to diagnosis ofcryptosporidium parasite from different regions in AL-Qadisiya province and thestudy designed to evaluate the microscopic features of the parasite.The results ofmicroscopic examination showed that the oocyst of parasite appearedoval-shaped orspherical objects with a color dark pink, or red on a blue ground ,21(21%) goats out100cases were positivewith significant differences at level (P < 0.05) The resultsshowed that the highest rate of infection (31.5%) were observed in the ages (6-12)year respectively, while the lowest rate of infection (11.1%) that was observed in theages (1-3) year . There are effects of the sex in the infection in goats. The highestrates of infection (33.3 %) were seen in December and lowest rate (8.3%) wereobserved in September , while the other months, showed different results, withsignificant differences at (P < 0.05) From the results , it was observed that the rate ofinfection in different study area were relatively close ,and ranged between (18.7-23.3%) , so there has been non- significant differences at level (P > 0.05)and using ofocular micrometer for determination of length and width of oocyststhat showedthemeasurement from (4.5-5)μm .

In order to investigate the histopathological features of ovine intestinal adenomas, the study achieved in 27 macroscopically suspected intestinal adenomas of sheep aged between 2-3 years, which diagnosed in Basrah abattoir, the intestines of slaughtered sheep were fixed and processed for light microscopy. The histopathological results showed multiple stages of neoplastic differentiation, mainly circumscribed areas suggesting adenomatous form by proliferating mucous glands in sub mucosal region of colon of varying sizes, some of which with clear proliferating hypertrophic and hyperplastic epithelial lining with area of angiogenesis and hemorrhage around them. Morever, the results showed circumscribed areas of adenomatous glandular structures enclosed by superficial mucosal epithelium and in sub mucosal region of rectum. It had been concluded that the ovine intestinal adenomas showed a degree of differentiation in mid aged sheep (2-3 years old aged) that may resembles other adenomatous intestinal lesions reported in more older age of others domestic animals.

The study was conducted at the of animal fields in AL-Qassim city, sheep in this fields was suffering from severe eye infection during the period April to October ,2015 .sheep was clinically examined and showed signs copious eye drops, increase body temperatures, swollen of eye with redness, eye pus in some cases, the sheep was checked clinically and eye swabs of 20 keratoconjuctivitis affected sheep carried out on the basis of their culturing,morphology, staining,biochemical tests and antimicrobial susceptibility testing was done by (disc diffusion method and well diffusion method) from present study .percent of infection was S.aureus(50%), M.ovis (33%)and Proteus spp.(17%) was isolated . Result of antimicrobial properties of Aloe Verawas evaluated in various in-vitro experiments against these species of bacteria S.aureus,M.ovis and Proteus spp. and showed good inhibition activity.In vivo study recovery from the conjunctivitis was record after 6 -10 days for animal treated with Pencillin-Streptomycine while group of extract that showed complete healing during period 6-10 day according totype and severity of infection, also there is no recurrent infection after treated with aloe Vera ointment and eye lotion , as well as Gide to done many of research on aloeVera for used in eye problem which consider very important in Veterinary Medicine .

The research includes superficial taxonomic study of the horse fly family Tabanidae in the Province of Basrah / South of Iraq , according to the seven districts of the province , There are Al-Mdainah , Al-Qurnah , Shatt Alarab, Abu Al-Khasib, Al-Zubair , Al-Fao and Basrah center . The Results of the study were showed recording three species for the first time in Iraq back to the three genera , and were Haematopota subcylindrica , Atylotus agricola and Hybomitra peculiaris .

The toxic influence of dietary copper(Cu) and cobalt (Co) on the accumulation and body weight examined in broiler chicken. This experiment was conducted to investigate the toxic effects of dietary Cu and Co on chicks body weight and organ, content of the tissues of these two metals was also detected. One day age chicks of Gallus gallus domesticus fed diet supplemented with 500, 1000,1500ppm of Cu, second group exposure to 100,500, 1000ppm of Co in feed daily during 4 weeks. The control groups were fed without supplementation of metals. The concentrations of Cu and Co resulted in increased of Cu and Co content in liver, gizzard and muscle. Body weight of chicks was decreased by Cu and Co high concentration treatments. On the other hand, Liver weigh in chicks was significantly (P

The present study was carried out to determine the vascularization of long bone in laboratory animal. Fourty healthy guinea pigs have been used and the result showed that, at 10 days old embryo showed newly differentiated blood cells at the future cartilaginous template. At age of 25-35 days only the osteoprogenitor cells, osteoblasts and osteocytes were seeing. At 43 old embryos the hematopoiesis and vascularization were clearly by formation free blood cells and newly formed blood vessels in the marrow cavity. At 54 old day embryo the hematopoiesis was increased and the differentiation of immature white blood cells was noticed at age of 65 day. At the postnatal periods showed a nutrient artery within marrow cavity.

This study was designed to explore the effect of nitrate ion on induction of diabetesexperimentally in laboratory mice.Fifteen white mice, 7-8 week olds were randomly dividedinto three equal groups. First group was administrated orally o.3 ml of nitrateion(concentration was 0.25gm/10ml D.W) daily for one month. Second group was administratedorally o.3 ml of potassium nitrate (concentration was 0. 5gm/10ml D.W) daily foronemonth. Third group was administrated orally with 0.3 ml of distilled water (D.W) daily forone month.After 30 post administrationthe concentration of blood glucose of infectedanimals treated with nitrate ion increase in both first and second groups when compared withcontrol group.The histopathological change study showed pathological lesions in pancreasof first grouptreated with nitrate ion showed the exocrine region and islets of Langerhans with damageddue to necrosis, while the second group wasinfected with nitrate ion showed the exocrineregion and islets of Langerhans with necrosis and congestion of blood vessel

The aim of this study was to evaluate therapeutic efficacy of atropine in case ofcholinesterase (ChE) inhibitors toxicity in chicks subjected to oxidative stress (OS) withhydrogen peroxide (H2O2). H2O2 at 0.5 % in drinking water induced OS at age of 7-14days in the chicks when given each day for 14 consecutive days. There was no change inthe acute median lethal dose (LD50) for diazinon (7.9 mg/kg, orally) for both H2O(control) and H2O2 groups. The therapeutic efficacy of atropine was decreased (265 %)when measuring the median effective dose (ED50) for treating the diazinon toxicity inH2O group (2.6 mg/kg, i.m.) and in the H2O2 group (9.5 mg/kg, i.m.). The signs of acutediazinon toxicity were found to increase in H2O2 groups when compared to H2O groupand there is slight decrease in plasma and whole brain ChE activities in H2O2 group whenwhen compared to H2O group. The data revealed a decline in atropine efficacy for treatment diazinon toxicity in chicks that suffered from OS status and it is recommendedhere to increase the dose of atropine in this case.
