Using dietary medicinal herbs is a useful approach to mitigate the effects of herbicide toxicity on aquatic animals. This study attempts to examine the consequences and potential mechanisms behind the dietary addition of horseradish tree (Moringa oleifera) leaf extract (MOLE) with the help of phytase addition to check the overall growth performance, biochemical changes, histological alteration, and gene expression in normal and after glyphosate challenge in Nile tilapia. A total number of 135 Nile tilapia fish (7.93 ± 0.03 g) were randomly assigned into three groups each in triplicate. The first group is the control group and fed basal diet; the second group supplied with MOLE (200 mg of extract/kg), and the third group was supplied with MOLE (200 mg /kg), and phytase (0.2g/ kg) for 8 weeks. After the feeding trial, each experimental group was divided into two subgroups to be unchallenged and challenged with glyphosate (30 mg/L of water). The results declared significant enhancements (P < 0.05) in Weight Gain Percent (WG%), Specific growth rate (SGR), and Protein efficiency ratio (PER) and reducing feed conversion ratio (FCR) with up-regulating hepatic gh, igf1,myogenine, intestinal ghrelin and NPY in fish groups fed MOLE and phytase compared with the control group.

These components might be accountable for the potential effects exerted by MOLE. Therefore, the current study suggests that dietary supplementation to MOLE and phytase can be used as substitute feed supplements in sustainable farming of Nile tilapia to defend against glyphosate challenges and enhance growth, antioxidant capacity, exerting anti-inflammatory and antiapoptotic effects under normal health conditions or post glyphosate challenge.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 3","pages":"135"},"PeriodicalIF":1.8,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11893658/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143597834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease is widespread in Africa, the Middle East and Asia and has been present in Egypt since 1988. LSD is mainly transmitted by blood-sucking insects. LSD is clinically distinguished by a high fever, skin nodules, and swollen Lymph nodes. Detecting sub-clinical disease can be challenging however, prompt laboratory investigations are vital. Skin lesions are the main source of infection, although the virus is shed through many excretions and discharges including semen. Disease confirmation in clinical laboratories includes detection of viral nucleic acid, antigen and antibody levels. Simple, adaptable, and quick assays for detecting LSDV are required for control measures. Vaccination, together with controlled quarantine and vector control measures, may be beneficial for preventing disease spread. Presently, a range of live attenuated vaccines, have been used in the field with different levels of protection and side effects. With high levels of vaccination coverage, attenuated Neethling vaccines have successfully eradicated of LSDV in Europe. Inactivated LSDV vaccines have also been demonstrated effective in experimental infections. Furthermore, due to its large genome, LSDV is being exploited as a vaccine delivery element, generating an innovative composite with additional viral genes by DNA recombination. Vaccines developed on this basis have the potential to prevent a wide range of diseases and have been demonstrated to be effective in experimental settings. In this review, we emphasizethe advances in diagnostic methods and vaccines developed last decade, thereby providing a basis for future research into various aspects of LSDV and providing information for possibility of disease elimination.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 3","pages":"134"},"PeriodicalIF":1.8,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11890411/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143582368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The abnormal puppy was diagnosed with gastro-thoracoschisis as it has a thoracoabdominal cleft from sternum to pubis, but without skeletal abnormalities. Further, it was revealed that there were some histopathological lesions in the liver and lung of the abnormal puppy. The second and third puppies delivered without difficulty, but only one of these puppies was alive at birth. This case represents the first report of gastro-thoracoschisis clinical case in Pomeranian breed. This case underscores the complexities of managing congenital anomalies in canine and highlights the need for further research to understand the etiology of GTS, which is observed more frequently in ruminants and sporadically in dogs.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 3","pages":"128"},"PeriodicalIF":1.8,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143558199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
