Experimental chicks were divided into two groups. First group (30 chicks) were fed on ration contaminated with 100ppb /kg ration, while second group (10 chicks) were kept as control and fed on ration free from OTA till the end of the experiment. Fifteen chicks from group 1and five chicks from group 2 were sacrificed 28 and 36 days post feeding (PF). The clinical signs, mortalities and lesions in addition to OTA residues were detected and recorded. The chicks in group 1 showed 20% mortalities beside diarrhea, dehydration and emaciation. The kidney lobules appeared pale with urates deposits due to intense nephrotic changes, nephritis, fibrosis and gout. The liver showed hepatic hemorrhages apoptosis, necrosis and hyperplastic bile ductules. Intense lesions in brain in the form of edema, meningeal lymphocytic cells aggregations, degenerated neurons and purkinje cells were recorded. GIT lesions (proventriculus and intestine) due to direct contact with OTA contaminated ration were also seen. OTA residue was higher in liver than kidneys while the lowest value was detected in skeletal muscle. It could be concluded that OTA induced neurotoxicity beside hepato-renal toxicity and GIT lesions due to its toxic effect and its adverse effect on growth performance.","PeriodicalId":137314,"journal":{"name":"Zagazig Veterinary Journal","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125042153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vaginal cytology was carried out during pregnancy period of these bitches by taking vaginal smears weekly to investigate vaginal cytological changes. Serial ultrasonography was performed daily on these bitches from the 15th day after the last breeding until birth day to determine the time of appearance of different gestational structures. The first observation of the extra-fetal and fetal structures was as follows: The yolk sac membrane was first detected as an echogenic U-shaped fetal membrane in a range of 24-25 days. A third echogenic fetal membrane, allantoic membrane, was first detected on Day 27. On Day 23, in the uterine wall surrounding the gestational sac, an apparently hyperechoic inner layer was differentiated to the zonary placenta which appeared as two thick bands one on either side of the fetus on Day 29. The embryo appearance was on Day 20.5. The early time of the position of the embryo either opposed to the uterine wall or dependent on chorionic cavity was nearly on Day 22 and on Day 24, respectively. The heartbeat, which is one of fetal vital signs, was detected as a bright echogenic flickering motion on Day 21. On Day 26 in mongrel bitches, the features of the embryo changed from an oblong to bipolar shape and form two loops of number 8, size and density the same. An anechoic area in the head of the embryo was detected on Day 29. The limb buds were firstly detected on Day 29. Fetal movement was firstly detected on Day 33. Meanwhile, the skeleton of the fetus was first detected as hyperechoic structure on Day 33.","PeriodicalId":137314,"journal":{"name":"Zagazig Veterinary Journal","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123401815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SHS has been described as a multi-factorial disease where the initial lesion mainly caused by avian Metapneumo virus (aMPV), while the clinical signs are a consequence of bacterial complications and the severity of the disease depends on environmental factors. This study was planned to detect and try to isolate the etiological agents of SHS from 40 broiler flocks in 3 Egyptian Governorates (Sharkia, Dakahlia and Damietta). The chickens incorporated swollen heads and respiratory manifestations as nasal discharges, coughing, tracheal rales and frothy conjunctivitis from different localities. Samples included trachea and lung tissues, choanal cleft swabs and scraps from sinuses and turbinates. The AMPV subtype B was detected in 5 flocks by Real Time Polymerase Chain Reaction (RRT-PCR) -using 2 specific probes for differentiation of subtypes A and B. the AMPV-subtype B was detected with the percentage of 12.5%. Bacterial examination of collected samples revealed presence of mixed infection in some of examined flocks with isolation of E. coli in a percentage of 70%; Proteus mirabilis 40% and Pseudomonas aeruginosa (25%).

Fecal samples (n = 113) were collected randomly from cattle at different localities in Sharkia Governate between September 2016 and August 2018. Samples were then examined parasitologically. Overall, GIN were found in 21 (18.6%) of the samples, the highest GIN prevalence was observed in winter (25.6%), while the lowest prevalence was in summer (10.3%). Adult cattle (42.9%) showed higher GIN infection than young calves (23.8%). Further, most of the infected cattle (92.4%) showed a light intensity of infection with GIN. The coproculture of infected fecal samples reveled that, 15 (71.4%) samples have single infection and 6 (28.6%) samples have mixed infection and Trichostrongylus spp. (41.9%) were the most frequently observed GIN, followed by Strongyloides spp. (35.2%), whereas, Cooperia spp. (8.7%) was the less frequently observed GIN. No significant difference (P = 0.78) was observed between using albendazole and allicin for treatment of GIN in cattle. The current study provides new and updated results that may help in the effort to control GIN. Also, this study shows that allicin could be used for treatment and control of GIN in cattle. However, further investigations in the efficacy of allicin in treatment of GIN in cattle and actual dose, are warranted.","PeriodicalId":137314,"journal":{"name":"Zagazig Veterinary Journal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130115951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Poultry, especially, chicken is the main reservoir of Campylobacter species. The uncontrolled use of antibiotics in prophylaxis and treatment of animals caused an increase in antibiotic resistance to macrolides and fluoroquinolones (FQ) which are considered the drugs of choice for treatment of Campylobacter infection. Recently, studies suggested that multidrug efflux systems have the main role in lowering the efficacy of new and old antibiotics. Consequently, efforts are made to find suitable substances to reverse the action of the efflux pumps and prevent antimicrobial resistance. The substances used for evaluation of efflux pumps modulation are either efflux pump inhibitors (EPIs) or efflux pump inducers. The different types of EPIs; phenylalanine arginyl β-naphthylamide, verapamil and phenothiazines, of different mode of actions were used to suppress the activity of different types of efflux pumps. Aspirin, a drug in livestock and poultry, is a nonsteroidal anti-inflammatory, which induces non-heritable resistance of different bacteria to multiple antibiotics. Moreover, it also increases campylobacter resistance to antimicrobials. Alpha-tocopherol represents a new alternative approach against bacterial resistance. It shows modulatory activity on efflux system, showing clinically relevant results. Therefore, it is important to study different resistance mechanisms of campylobacters.","PeriodicalId":137314,"journal":{"name":"Zagazig Veterinary Journal","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133130061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results of genetic correlations showed great variability from very high positive to very low negative values. High heritability estimates were recorded for all studied traits with the exception of days in milk, calving interval and days open which revealed low estimates. The ranges of cows breeding values have been found to be higher than either sires or dams for all studied traits. Genetic trends were positive for 305-day milk yield (2.68 kg), age at first calving (0.020), fat yield (0.031kg), fat% (0.001%) and protein % (0.002%), but were negative for protein yield (-0.098 kg) and days open (-0.219). In conclusion, higher range of the cow breeding values than either sires or dams revealed a wider genetic variation and a good opportunity for selecting the superior cows. Positive genetic trends for 305-day milk yield, age at first calving, fat%, fat yield and protein% indicated that there was a genetic improvement in these traits in desirable direction, but negative genetic trends for days open and protein yield indicating a decrease in mean breeding value for these traits over the study period.","PeriodicalId":137314,"journal":{"name":"Zagazig Veterinary Journal","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116769286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
