However, this type of data is often kept in separate storage towers, making it incapable of practicing its potential to boost animal welfare. Lumpy Skin Disease (LSD) is a serious threat to the health of cattle worldwide and has caused financial problems for many cattle farming enterprises. It has been shown that combining machine learning (ML) and artificial intelligence (AI) with biosensor data and conventional visual inspections can improve the identification and diagnosis of this serious condition. Methods: This study presents an extremely precise livestock farming framework that combines data streams from a wide array of disciplines of dairy cattle to see if ever wider/vast data sources enhance the overall projections for diseases and if using the more complicated prediction models can reimburse for less diverse data to some extent. Using images from the farming landscape, this study highlights the utility of convolutional neural networks (CNNs) in the identification of the Lumpy Skin Disease Virus (LSDV) in animals. Result: An analysis of the relative weight given to individual factors in predicting accuracy shows that disease in dairy cattle results from the intricate interactions between many life domains/parameters, such as housing, nutrition and climate; that prediction performance is enhanced by incorporating a wider range of data sources; and that current information can be repurposed to produce useful information for vaccine development. The study highlights the potential of data-driven dairy interventions, focusing on artificial intelligence for disease prediction in cattle, to improve animal welfare and reduce the risk of disease. A Convolutional Neural Network (CNN) based model effectively classified skin conditions with an overall accuracy of 73.89% after 27 training epochs. This study demonstrates CNN’s useful applications in the field of veterinary medicine by highlighting its potential for early detection of Lumpy Skin Disease (LSD).\u0000","PeriodicalId":507727,"journal":{"name":"Indian Journal of Animal Research","volume":" 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831539","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 effectiveness of control tools is impeded by the high costs associated with animal experimentation, an incomplete understanding of host immune systems and a scarcity of immunological reagents. 99mTc radiopharmaceuticals, known for their versatile chemistry, play a crucial role in preclinical research and drug development. The objective of the present study was to develop nuclear medicine-enabled strategies for custom designing and uplifting engineered vaccines, specifically nanoparticle vaccines, in guinea pigs. Methods: In the present study, we elucidate the technique used for direct radiolabelling of the FMD vaccine and its subsequent distribution within guinea pigs. The study involved the evaluation of 99mTc-radiolabeling and quality control, as well as the disposition of the 99mTc-FMD vaccine in guinea pigs. Result: Radiolabelling and stability studies showed 95.00% efficiency and 92.93% stability.

In the field of medical science, wounds are a significant issue that requires immediate attention. Lavandula species are used in the food, perfume and cosmetics industries due to their antimicrobial, anti-inflammatory and wound-healing properties. Methods: The present study was done to assess the biocompatibility, antimicrobial and wound-healing potential of L. dentata leave methanolic extract (LE) that is cultivated in the Taif region of Saudi Arabia. The biocompatibility of LE was analyzed against the normal human skin fibroblast (HSF) cell line using SRB assay. A quarter of LE IC50 was used for wound healing assay. Finally, Escherichia Coli, Staphylococcus aureus, Pseudomonas aeruginosa and Streptococcus pyogenes were used to determine LE antibacterial potential through the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) measurement. Result: LE appears safe on HSF cell line with IC50 = 97 mg/mL. LE decreased wound width, wound area and the mean cell migratory rate of wound border cells during scratch closure, while increased the wound closure% in a time-dependent manner compared to negative control. LE shows antimicrobial potential against all four strains at MIC and MBC greater than 3.0 mg/mL, except for Streptococcus pyogenes MIC= 3.0 mg/mL. In conclusion, LE offers therapeutic benefits against wound healing with an antimicrobial effect, however, higher concentrations of LE should be used to assess its effect.\u0000","PeriodicalId":507727,"journal":{"name":"Indian Journal of Animal Research","volume":"8 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141648175","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}

Its production has increased significantly in recent years and it has become one of the most important animal sources in the Kingdom of Saudi Arabia. Coccidiosis is one of the most dangerous diseases affecting rabbits and other animals causing global economic losses. Plant extracts have been used as potential alternatives to chemotherapy because they do not have the negative consequences of tissue deposits and drug resistance. Methods: The current study examined the antioxidant activity of Vitis vinifera leaf extract (VVLE) in New Zealand rabbits infected with Eimeria stiedae. The extract was subjected to phytochemical analysis by FT-IR. A total of 35 male New Zealand rabbits were divided into seven groups. Group 1 served as the uninfected, untreated (negative control) group. Group 2 uninfected and treated at 400 mg/kg of extract to test for toxicity. Group 3 represented the infected, non-treated (positive control) group. While, groups 4, 5 and 6 comprised infected treated with at100 mg/kg, 200 mg/kg and 400 mg/kg of extracts, respectively. Finally, group 7 consisted of infected rabbits treated with Toltrazuril at a dosage of 5 mg/kg body weight. Result: The analysis of phytochemicals by FT-IR for Vitis vinifera leaf extract revealed the existence of 15 biologically active compounds. VVLE was able to decrease the induced weight loss due to infection. Moreover, the oxidative status due to E. stiedae infection had been changed after treatment with VVLE where the level of glutathione, malondialdehyde and nitric oxide was improved indicating the antioxidant activity of the VVLE. Our findings suggested that VVLE could boost the induced oxidative stress in the liver of infected New Zealand rabbits, but studies are needed to determine the mechanism of VVLE.\u0000","PeriodicalId":507727,"journal":{"name":"Indian Journal of Animal Research","volume":"10 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141646864","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}

A slaughterhouse study helps to assess the disease status of herds and contains valuable information about the incidence and epidemiology of animal diseases. Haemoprotozoan diseases are one of the major problems which adversely affect the health and productivity of cattle. The diverse climatic zones of India are highly conducive to the survival and propagation of vectors and vector-borne pathogens. However, there is no data on proper slaughterhouse study of bovines in Mizoram even in India for determination of the prevalence of haemoprotozoan infections. Methods: The blood samples were collected in an EDTA vials. The blood smear was prepared, stained with Giemsa stain and examined for the presence of haemoprotozoan. The DNA was isolated from positive samples by use of a DNeasy Blood and Tissue Kit. Then PCR was performed for all the isolated DNA collected from positive samples. After confirmation through PCR, the representative samples for Anaplasma sp. and Theileria sp. were sent for sequencing. Then the sequencing results were annotated using BLAST, ClustalW multiple alignment program of MEGA9 software. The phylogenetic tree was generated by using the Neighbour-Joining method, keeping bootstrap consensus from 1000 replicates. Result: After the blood smear examination, PCR was performed for confirmation. Molecular detection of Anaplasma marginale, Theileria orientalis was done. Molecular characterization of 2 isolates from Anaplasma marginale and Theileria orientalis was performed by sequencing. The sequence analysis of rpoB gene of isolates of Anaplasma revealed both the isolates were placed in the same clade in the phylogenetic tree.

Lead acetate poses a significant health threat due to its toxic effects on various organ systems, particularly the kidneys, which play a crucial role in waste elimination and maintaining physiological balance. Methods: The study design involves the administration of lead acetate to induce subchronic intoxication in experimental rats, alongside treatment with broccoli extract and vitamin E to assess their protective effects. Result: Biochemical analyses reveal significant increases in urea, uric acid, creatinine and BUN levels in the lead acetate-treated group, indicative of impaired renal function. However, treatment with broccoli extract demonstrates a significant reduction in these biomarkers, comparable to the effects observed with vitamin E treatment, suggesting potential renoprotective benefits. Histopathological examination corroborates these findings, with the lead acetate group exhibiting severe renal damage, including degeneration, necrosis and inflammatory cell infiltration, while broccoli extract treatment partially mitigates these effects.\u0000The study highlights the importance of natural compounds like broccoli in combating heavy metal-induced renal toxicity and underscores the need for further investigation into their protective mechanisms.
