While caprine meat is marketed at refrigeration temperature it is important to minimize microbial deterioration, and oxidation to ensure meat safety and quality. Thus, this research was done to assess the effect of basil essential oil (BEO) used at different three concentrations (0.5, 1, and 1.5%) on the sensory evaluation, chemical quality (pH, thiobarbituric acid “TBA”, total volatile nitrogen “TVN”), and microbiological quality (total bacterial count, enterobacteriaceae, staphylococcal count, E. coli , total yeast & mold) of caprine meat stored for 12 days at 4°C. The obtained results demonstrated that addition of BEO at different concentrations improved the sensory properties of treated caprine meat as compared with control; Regarding chemical quality it was found that addition BEO with different concentrations decrease pH, TBA, and TVN values in treated caprine meat as compared with control samples this meaning that BEO had an antioxidant effect. In relation to microbiological quality, it was found that different concentrations of BEO decrease microbial count in treated caprine and extends shelf until day 12 of meat storage as compared with control samples. The concentration of 1.5% BEO gave the highest microbiological inhibition. Control caprine meat starts to decompose at 6 th of storage while addition of BEO at concentration 0.5% extends shelf life till 9 th day of storage and BEO at 1 and 1.5% extend shelf life until day 12 of storage. The obtained results revealed that BEO at 1% significantly improved sensory properties, chemical and microbiological quality of caprine meat although BEO at concentration 1.5% was more effective but gave strong odor and color changes which may be undesirable for consumers. The result of this study concludes that BEO has an antioxidant and antimicrobial effect and could be used as natural preservative for caprine meat during refrigeration temperature","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132967515","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}

One hundred and thirty-nine dogs representing fifteen breeds from the Directorate of Veterinary Medicine in Alexandria governorate were involved in the study between November 2020 and April 2021. After a thorough clinical examination and filling out a pre-designed questionnaire, random blood glucose (RBG) test was performed for all animals. Those with high RBG levels were subjected to a complete blood picture (CBC), liver and kidney functions, and HbA1c. A control group of 50 dogs of similar age, sex, breed, and management was selected and subjected to the same analyses. The prevalence of DM among the studied dogs was 7.2 %. All diabetics suffered from polydipsia and polyuria, while 60% suffered from polyphagia and 80% suffered from weight loss. No significant impact of DM on temperature, respiratory rate, anaemia, liver enzymes and platelets count, but there was a significant increase in pulse rate. There was a significant impact of DM on eyes as 80% of the diabetic dogs suffered from cataracts. It had a significant impact on total leucocyte count and on the renal function, where 70 % of the diabetics had impaired renal functions. Regarding the risk factor analysis associated with the occurrence of DM, only breed has been identified as a potential risk factor for cDM (canine diabetes mellitus). So, a spotlight must be thrown on cDM as an essential and not uncommon dog’s disease, and we need to raise awareness of cDM among veterinarians and dogs’ owners.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124460923","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}

Two groups were daily fed on H. pylori suspensions in food and water, whereas the third group was kept as a control group. Serum iron, ferritin, copper (Cu), zinc (Zn), magnesium (Mg), lipid profile, SGPT (ALT), SGOT (AST), and full blood picture were all measured at day 90 (the end of the experiment). The findings demonstrated that H. pylori stool Ag was present in the feces of infected rat groups and was elevated throughout the trial. Antibodies against H. pylori have increased in serum. Hematological and biochemical markers, particularly iron and ferritin, as well as hemoglobin and leukocytes, were all negatively affected. In addition, all signs of gastric inflammation were demonstrated among the infected groups. Overall, after exposure to H. pylori infected food and water, numerous haematological parameters were disturbed and seriously impacted various organs.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114326425","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}

The present study's objective was to use short sequence repeats markers (SSRs) in the early sexing of O. niloticus . Molecular markers identification in fish includes SSRs markers that were very useful for investigating sex-determination system, sex-related genes, and sex chromosomes. The fin-clip tissue of examined fish was used for DNA extraction and the amplification of SSRs and sex determination; twenty primer pairs were tested. The results showed that, from the tested 21 primers of SSRs markers, four primers had significant differences between males and females. It was observed that females were homozygous, and males may be heterozygous or homozygous for the alternative bands. The females were homozygous, males were heterozygous for two SSRs markers, the females were homozygous, and males were homozygous for the alternative alleles for the other two markers. In conclusion, the results of the present study and the previous ones confirm the possibility of using short sequence repeats markers (SSRs) in the sex determination of fish species, including Nile tilapia ( Oreochromis niloticus , L.). SSRs markers could be used in the early sexing detection of the Nile tilapia breeding programs and for producing supermale YY without needing progeny test.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133887642","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}
