They are resistant to many commonly used antibiotics due to the presence of antimicrobial resistance (AMR) genes. A study was conducted to evaluate the AMR profiling of CNS isolated from bovine subclinical mastitis.Coagulase negative staphylococci were isolated from 49 (44.95 per cent) of the subclinical mastitis samples. Disc diffusion assay revealed that highest resistance was shown against gentamicin (42.85 per cent) followed by methicillin (32.6 per cent), ceftriaxone – tazobactam (24.48 per cent), enrofloxacin (20.4 per cent), tetracycline (16.32 per cent) and least resistance to cotrimoxazole (4 per cent). Genotypic characterisation of AMR genes such as mecA, aacA-aphD and norA by PCR was done for determining resistance to methicillin, gentamicin and fluroquinolone resistance. The CNS carried aacA-aphD, norA and mecA in 44.89 per cent, 32.65 per cent and 14.28 per cent, respectively. Comparison of phenotypic and genotypic characterisation of AMR in CNS was carried out by McNemar test and it was found that there was significant difference between the presence of mecA gene and methicillin resistance. There was no significant difference noticed forcharacterisation of phenotypic and genotypic AMR of CNS for gentamicin and fluroquinolone resistance.","PeriodicalId":52568,"journal":{"name":"Journal of Veterinary and Animal Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70628020","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}

Thirty Large White Yorkshire female piglets belonging to Centre for Pig Production and Research, Mannuthy, weaned at 21 days of age were allotted to three dietary treatment groups (T1, T2 and T3) with five replicates for each treatment. Piglets were fed pre-starter ration till they gained a body weight of 5 kg and then on starter ration from 5 to 18 kg body weight. The dietary protein in treatments T2 and T3 were reduced by 15 and 25 per cent respectively than that of control treatment (T1). Five amino acids viz., lysine, methionine, threonine, valine and isoleucine were supplemented to all treatment groups to meet the requirements as per NRC (1998). Body weights of animals were taken at weekly intervals. There was no significant difference in average body weight among three treatment groups from first to third week. From fourth to eleventh week, the average weekly body weight of T1 was significantly higher than T3. The average daily gain was significantly different among three treatment groups with highest values observed for group T1, followed by T2 and T3. The feed conversion efficiency was statistically similar among treatment groups. Total viable count and coliform count were significantly lower in the faeces of piglets fed with low protein diets, indicating a reduction in microbial population in faeces of piglets in relation to reduction in dietary protein level. From the overall results, it could be concluded that reducing the dietary protein levels had resulted in reduced growth performance in early weaned piglets, in spite of being supplemented with selected essential amino acids","PeriodicalId":52568,"journal":{"name":"Journal of Veterinary and Animal Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70629443","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 was conducted to synthesise silver nanoparticles (AgNPs) from aqueous extract of neem leaves. The phytochemical screening of the aqueous extract of neem leaves was also performed for determining its active principles. The qualitative phytochemical screening revealed that the aqueous extract of neem leaves contained phytochemicals like steroids, alkaloids, phenolic compounds, tannins, flavonoids, saponins and terpenoids. The AgNPs synthesised were characterised using X-ray diffraction analysis which revealed that synthesised AgNPs were face centred, cubic and crystalline in nature and the sample contained silver nanoparticles in a high concentration. The antibacterial activity of the green AgNPs against E. coli isolates including the reference strain was tested and observed that the AgNPs exhibited antibacterial activity though a significant zone of inhibition was not obtained. Based on the results obtained, it could be concluded that silver nanoparticles could be efficiently synthesised from neem leaves and could be utilised in various fields especially in nanotechnology.","PeriodicalId":52568,"journal":{"name":"Journal of Veterinary and Animal Sciences","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136301819","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}

Ketamine and midazolam were intravenously administered at dose rates of 4.0 and 0.2 mg/kg body weight respectively, to induce anaesthesia. Isoflurane was used to maintain anaesthesia after endotracheal intubation, at a concentration of 1.05 ± 0.97 per cent concentration in 100 per cent oxygen using a large animal anaesthesia machine. Simultaneously, intravenous lignocaine was administered at a bolus dose of 2 mg/kg body weight followed by a CRI of 3 mg/kg body weight/hour using a volumetric infusion pump. Isoflurane sparing effect of intravenous lignocaine reduced the required concentration of isoflurane for maintenance. The third plane of surgical anaesthesia was maintained and various surgical procedures were done. Recovery was smooth. Other than the mild regurgitation of ruminal fluid in an animal, no anaesthetic complications were noticed.","PeriodicalId":52568,"journal":{"name":"Journal of Veterinary and Animal Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70628402","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}
