This study was done to evaluate and study the decaying curve of IBD MDAbs of the native chicken breeds including (Fayoumi, Dandrawi, Senawi and Baladi) were taken in consideration as compared with (Lohmann white) layer type breed. The results showed that the decline of maternal immunity of IBDV in Lohmann is the faster followed by Senawi, Baladi, Fayoumi and Dandrawi and the 1 day IBD ELISA titers were shown to be nearly equal in Senawi (5449 ± 371) and Lohmann (4536±437) and titer of Baladi chicks was close to the for mentioned two breeds (5327±371), the Dandrawi (4649±331) and Fayoumi (4596±857) are lower but close to each other. The standard deviation (SD) values recorded in Fayoumi breed showed great variation in the recorded titers, while of the other 4 groups seamed to be homogenous. Comparing the 22 day decline manner in titer it was clear that the loss in titer in Fayoumi (3494) and Lohmann (3413) was nearly equal and followed by Dandrawi (3093) and Baladi (2972) those showing lower titers. The recorded unprotected titer ≤ 400 was detected at 43 days in Lohmann, Baladi and Senawi, 37 days in Dandrawi and 31 in Fayoumi. Percentage of decline from its original values showed that Fayoumi last (75.95%) at 22 days followed by (66.53%) in Dandrawi followed by (62.78%) Lohmann,(55.79) Baladi and (55.19) Senawi. Different breeds showed different slope values that indicate differences in the decay of maternal antibodies. The predication of antibody titer for each breed as the slope in decline curve in Lohmann chicks showed highest values followed by Dandrawi chicks while the Fayoumi and Baladi were as the same values and on the other hand the Senawi showed the lowest value.

The aim of this study is to determine the effects of boron supplementation in ration of rams on their productive activity and semen quality. For that purpose, twelve rams were divided into two groups (6 rams/ each). Rams of the first control group were fed the basal ration. Concerning the second group (boron group), the rams were fed the basal ration plus 400 mg boric acid (BA) / kg diet as a source of boron. The rams in both groups fed their corresponding ration for 4 months ad libitum. Blood samples were collected monthly throughout the experimental period. Semen samples were collected at the 12th and 16th weeks of the experiment. The results clarified that the serum levels of tetraiodotyrosine (T4) were observed to be elevated significantly (P<0.05) with growing of age in the rams fed B, but they didn't change in the control group. In addition, the semen quality was maintained normal with boronsupplementation as the individual sperm motilities and live/dead sperm cells percentages were similar to control. Also, boronsupplementation didn't induce any adverse effects on the serum levels of Mg when compared to control group. Thus, boronis considered a potential and useful supplement in ration of rams to improve the thyroid activities and didn't induce any adverse effects on either semen quality or serum magnesium level in rams.

Diabetes is characterized by hyperphagia, and polydypsia. However, the mechanisms by which diabetes produces these effects are not clear. This study was conducted to examine changes in serum insulin and leptin levels in induced-type 1 diabetes mellitus in relation to concomitant changes in body weight, glycemic state and lipid profiles in rats. Moreover, we aimed to clarify that the treatment with lipoic acid (LA) is capable of reversing these effects or not. Ninety-six male rats were divided into 3 groups, control group (32 rats) was considered as normal non-diabetic, 64 rats were subcutaneously injected with alloxan (120 mg/kg.b.wt) for induction of diabetes. Then the diabetic rats were divided into two equal subgroups, the first is diabetic group that was not treated with LA, and the other is LA-treated diabetic group that was treated with LA at a dose 100 mg/kg b.wt / day for four weeks. Body weight, serum lipid profile, glucose, insulin, homeostasis model assessment– insulin resistance (HOMA-IR) and leptin were measured. The data showed significant increase in serum triacylglycerol, total cholesterol and glucose levels as well as HOMA-IR while significant decrease in the mean body weight gain, serum insulin and leptin levels in diabetic group in comparison with control group. The treatment with lipoic acid led to significant decrease in serum fasting and postprandial glucose, triacylglycerol and total cholesterol levels as well as slight decreased HOMA-IR with significant increased levels of serum insulin and leptin in comparison with diabetic group. It could be concluded that alloxan-induced diabetes led to hyperglycaemia, insulin resistance, hyperlipideamia and hypoleptinamia. Moreover, treatment with lipoic acid ameliorates these changes and improves insulin sensitivity.

Fifty raw ewe’s and goat’s milk samples (25 of each) were examined for total viable, psychrotrophic count and the presence of foodborne pathogenic microorganisms. The obtained results revealed that the mean total bacterial counts/ml were 1.9 x103 and 1.4 x103 in the examined samples, respectively. Psychrotrophic bacteria could be detected in all examined samples (100.0 %) with mean values of 7.8 x10 and 6.3 x10/mL, respectively. Staphylococci, Enterococci, and E. coli , were detected in (52.0 & 84.0 %), (44.0 & 36.0 %) and (36.0 & 44.0 %) of the examined samples with mean values/ml of (7.2 x10 & 6.1 x10), (2.5 x10 & 2.4 x10) and (3.0 x10 & 2.1x10), respectively. The predominant isolated bacterial strains were Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Enterococcus faecium and E. coli, at percentages of (24.3 & 19.2 %), (16.2 & 32.7 %), (10.8 & 13.5 %), (19.0 & 17.3 %) and (29.7 & 17.3 %) of total isolates, respectively. On the other hand, Clostridium perfringens, Campylobacter jejuni, Corynebacterium bovis and Salmonellae failed to be detected in all examined samples. The sanitary and public health importance of these organisms as well as preventive measures to improve the quality of milk and safeguard the consumers from infection were discussed.

FMD virus type A/1/ Egypt 2006 was inactivated with 0.1 M of BEI (Binary ethylene imine) formed by cyclization of 2- Bromoethyl-amine hydrobromide (BEA) in 0.2 N NaoH at 37oC with PH 8.0 for 24 hours. The virus was complete inactivated after 15 hours post inactivation. No residual virus particles were detected when inoculated in tissue culture. The inactivation rates are linear with a regular loss of titer ranged from 0.5- 1.0 log10 / hour. Control sample of virus at 37oC without BEI showed only a loss of 1.0 log from the original infectivity titer after 24 hours. The sample of virus which kept at -20oC, without BEI, showed loss 0.3 log10 from its original infectivity titer after 24 hours. There is no change in the complement fixing antigen before and after inactivation process with BEI inactivator and in the CFT 7 dilution of antigen was stable (fixed) pre and post inactivation of virus. Also it was found that the inactivation rate of BEI was higher than the inactivation with pure Ethylenimine (EI) and formalin.

The study was conducted to determine the prevalence of Peste des Petits Ruminants in different breed of goats based on age, sex, seasonal variation and vaccination status at Upazilla Veterinary Hospital, Pirojpur Sadar, Bangladesh during the period from January 2015 to December 2015. A total of 319 cases of different breed of goats were recorded in which 43 (13.48%) were infected by Peste des Petits Ruminants. The diagnosis of Peste des Petits Ruminants was performed based on clinical history, clinical signs and some laboratory techniques. The major clinical signs were high fever, nasal discharge, rapid breathing, mouth lesions and bloody diarrhea.The prevalence was highest in Black Bengal goat (6.90%) compare to Jamunapari (3.76%) and crossbreds (2.82%). Female goats were more susceptible (60.47%) than the male goats (39.53%). 5 months to 11 months aged goats showed highest prevalence (48.84%) followed by 1 to 3 years aged goats (27.91%) and 0 to 4 months aged goats (23.26%). In winter season, the prevalence was highest (55.81%) compare to summer (25.58%) and rainy season (18.60%). The non-vaccinated goats were more susceptible (90.91%) than the vaccinated goats (9.09%).Those prevalence of Peste des Petits Ruminants in different breed of goats based on age, sex, seasons and vaccination will help clinician to know the occurrence of Peste des Petits Ruminants in this area and will help them to take proper preventive measures.

Infection with Neospora caninum in a dog is described. The predominant clinical findings were proprioception deficit, involuntary and continuous contracture of the pelvic extremity muscles. N. caninum is structurally similar to Toxoplasma gondii, but it is immunologically distinct. Therefore, infections had been misdiagnosed as toxoplasmosis. The diagnosis was confirmed by an immunofluorescence antibody test. The parasite is sensitive to clindamycin and trimethoprim/sulphonamide, however the prognosis is poor especially if the muscle contractures have occurred.

This study was carried out to determine the prognostic importance of troponin enzyme levels in lambs with White Muscle Disease (WMD). Materials and Methods: This study consisted of 50 male and female lambs aged 0-3 months old, 30 of which had clinical white muscle disease (Group I) and 20 of which were healthy (Group II – Control Group). Group I was composed of lambs that showed clinical symptoms of the disease. The disease was also identified by laboratory analysis. The lambs in this group were treated and the course of the disease was followed for 15 days.Compared with the control group, the Group I before treatment results were as follows: AST, LDH, CK, CK-MB, Troponin I and T (P<0.001) were high, while GSH-Px (P<0.001), SOD (P<0.01), Se (P<0.01), Retinol and Tocopherol were low. Compared with the control group, the Group I After Treatment results were as follows: AST, CK, Troponin T (P<0.001) were high, LDH (P<0.01) was high and GSH-Px (P<0.01) was low. Comparing Group I Before Treatment and After Treatment results, AST, CK, CK-MB and Troponin I (P<0.001), as well as GSH-Px, SOD and Se (P<0.01) were high. It was determined that LDH decreased and Tocopherol increased. Whereas Vitamin D3 was determined to be insignificant in all three groups, the levels of CK-MB, Troponin I, Retinol, SOD and Se were insignificant in the After Treatment and control groups, and the Troponin T and retinol values were measured to be insignificant in the Before Treatment and After Treatment groups.To conclude, measuring the AST, CK, CK-MB, LDH values as well as Troponin can be an important parameter for the identification and prognosis of WMD.

Besides the yield loss of the pigeons those are infested with ectoparasites they are also susceptible against the other infections because of weakened immunity. Thus it has been evaluated the situation of ectoparasites of domestic pigeons and determined the prevalance in Antakya region. Materials and Totally 100 domestic pigeons (Columba livia domestica) which are fed for hobby in Antakya region were examined with respect of ectoparasites. The prevalance of ectoparasites of domestic pigeons has been determined and identified according to the literature.The prevalance of ectoparasites of domestic pigeons was determined as 52% and three different ectoparasites were detected. Columbicola columbae was the dominant species with a percentage of 45%, Argas reflexus and Pseudolynchia canariensis were also dedected with a percentage of 5% and 2%, respectively. Despite the higher percentage of infestation in female pigeons (54,5%) when compared with males (48,9%) and adults (56,9%) when compared with juveniles (42,9%) no significant difference was found statistically (p>0.05). But louse infestation of adult pigeons (58,3%) was significantly higher than the juvenile pigeons (28,5%) statistically (p<0.05).The yield and perfomance loss in domestic pigeons should not be ruled out. Therefore hygien of shelters and ventilation is crucially important. Ectoparasiter situation should be monitorized and gotten under controlled.
