Two slaughtering methods (with and without electrical stunning) for broilers were used in this study, using 20 broilers (10 males and 10 females) at a rate of 5 birds for each method. The results showed that there was a significant (P<0.01) increase in the amount of blood collected from slaughtered females by using electrical stunning method when compared with the females slaughtered without electrical method. The amount of blood collected from male broilers of both gropes and methods showed no significant differences. It was concluded that electrical stunning of broilers gave better results of bleeding than birds stunned without electrical stunning. Moreover, it does not object with Islamic believes since birds were alive at slaughter time.

Two commercial types of Hydro pericardium Hepatitis Syndrome (HHS) oily inactivated vaccines were evaluated. The first was (Angavac) French in origin (Merial Co.) & the 2nd is (Nobilis Hepatitis) Holland in origin (Intervet Co.). A unified program of vaccination had been used for both vaccines. One & ten days old chicks were vaccinated by subcutaneous & intramuscular route of injection with both vaccines in each age separately . Serum antibodies titer weekly measured by using Indirect haemagglutination test (IHA) & agar gel diffusion test. Challenge test at 4 week of age was done by virulent avian adeno virus serotype – 4 (VAAV-4) as well as virulent field isolate was used as challenge virus. The result showed highest antibodies titer at week age. Angavac vaccine gave highest titer than Nobilis Hepatitis vaccine & IHA was more sensitive than AGDT. All groups vaccinated with Angavac gave 100% protection in challenge test with (VAAV-4) at 28 days. While in Holland vaccine the protection ratio was 60-80% only, but the ratio of protection of both vaccines did not exceed than 40-50% when the field isolate was used as challenge virus.

This study searched the microscopical effects of garlic oil at a dose of 50 mg daily for 60 days on tissues of heart , liver, and kidney in female rabbits. The results revealed hyperatrophy in cardiac myocyte, acute cell swelling in hepatocyte and epithelial cells that lined renal tubules. Complete lipid profile was also described.
The study also proved that garlic oil had a good antioxidant effects toward the meliorating progression of atherumatous lesion. Antioxidative effects also explained by significant reduction in lipid profile parameters (except an elevation in HDL-C), as well as elevation in tissue GSH and reduction of tissue MDA, as compared with control group. One more result , this study was suggest on the therapeutic efficiency of garlic oil and vitamin E for 15 days after exposure to hydrogen peroxide for 60 days. The therapeutic effects interpret within the significant reduction in the level of total cholesterol, triglyceride, LDL-C, VLDL-C, atherogenic index and significant increase in the level of HDL-C. In addition to significant increase in the level of GSH and significant decrease in the level of MDA. The histopatholgical changes, reveled less reduction in atherosclerotic lesions. This study concluded that garlic oil have a capability to decrease the level of lipid profile as antiatherogenic. In addition, the ability to decrease the level of lipid peroxidation MDA, and to increase the level of GSH as antioxidant.

Birth weight of 149 Friesian, 270 Sharabi and 121 crossbred calf's males and females were utilized. The mortality rates have been obtained from birth until weaning for each breed in males and females. Average birth weight in male's survival group for sharabi, Friesian and crossbred were 20.94, 30.82 and 30.19 kg respectively, and in females were 18.42, 29.11 and 28.10 kg, respectively. Birth weight in Sharabi was significantly different (P<0.01) from Friesian and crossbred in both males and females. In mortal group the birth weight was significantly (P<0.01) less than survival group in both sexes and for each breed.
Mortality rate in males and females were (14.1%, 16.7%) in Frieasian, (21.2%, 23.6%) in Sharabi and (8.8%, 7.5%) in crossbred respectively, which differ significantly (P<0.01) among breeds. But, no significant difference between males and females was detected.
The Point-Biserial correlations between mortality anb birth weight were negative and highly significant for the three breeds in males and females. The threshold point of birth weight values which gave the best efficiency, the efficiency were for Friesian (89%, 85%), Sharabi (86%, 80%) and crossbred (93%, 94%) for males and females calves respectively, Fm and Fc, as well as efficiency were determined. Advantageous results were in least specificity Fm and Fc, and in high efficiency and sensitivity.
The threshold values of birth weight for classifying mortal and survival groups were (25.6, 26.6 kg) in Friesian, (16.6, 16.1 kg) in Sharabi, and (24.6, 22.6 kg) in crossbred in male and female, respectively.

In this study, the effect of autotransplantation and laser irradiation on the healing of experimental induced non-union fractures in the femoral bone were investigated clinically and radiographically in 12 dogs. The fractures were left without fixation for 40 days and over, and following the occurrence of non-union state the fractures were treated at 3 different schedules in the experimental animals, which were divided into three groups, each containing 4 dogs:
Group 1 (control): the non-union fractured femoral bones were treated by the routine surgical procedures using intramedullary fication achieved with Steinmann intramedullary pins.
Group 2 (intramedullary fixation with autotransplantation of bone marrow): following the surgical treatment of non-union fractured femoral bone and their fixation by the Steinmann intramedullary pins (by the same procedure applied in group 1), 4-6 ml of fresh bone marrow was implanted at the fracture site. The bone marrow was aspirated freshly and aseptically from marrow cavity of the opposite femur from the same dog.
Group 3 (autotransplantation of bone marrow with He:Ne I.R. laser irradiation): in addition to the procedures applied in group 2, the surgical site was exposed to laser irradiation type He:Ne I.R. with a total dose of 2.7 J/cm2 for 12 irradiation sessions. Each daily irradiation session was for a period of 5 min for 3 successive days, followed by one-day rest.
The concluded results were:
1-autotransplantation of fresh bone marrow at the site of the treated non-union fractures has a role in accelerating or improving the healing process, by promoting excessive callus formation, whereby the fracture line disappeared at the end of the 4th post-treatment week.
2-the use of laser irradiation with autotransplantation of fresh bone marrow, greatly improved the healing process by increasing the periosteal reaction and callus formation, and lead to disappearance of the fracture line at the end of the 3th post-treatment week. Furthermore, this technique improved the functional use of the affected limb in comparison with groups 1 and 2.
3- the laser irradiation made the remodeling stage shorter (finished within about 3 months) in comparison with group 1 and 2, in which it continued for more than 3 months.
