Methods: The collected foeti of sheep were divided into three age groups viz. early prenatal (up to 50 days), mid prenatal (51-100 days) and late prenatal (101 to 150 days). The samples of heart were processed by routine paraffin technique and cryo technique and after section cutting, the slides were stained by various histochemical staining methods. Further, fresh pieces of the heart samples were also processed for getting tissue extracts for the biochemical analysis. Result: It was revealed that the PAS activity was observed in the cardiac wall, interatrial septum and interventricular septum in the sheep foeti at all stages of gestation. A variable degree of acid phosphatase activity was noted in the myocardium of heart wall in the sheep foeti at all stages of gestation. The lipid deposition also increased with advancing age in the myocardium of cardiac wall, interatrial septum and interventricular septum in the heart of sheep foeti. The activities of various enzymes like creatine kinase, alkaline phosphatase, serum glutamic-pyruvic transaminase and serum glutamic-oxaloacetic transaminase were high in left ventricle than the right ventricle in the heart of sheep foeti. Certain protein bands of specific molecular weight appeared in the ventricular tissue at specific age of gestation in addition to a group of common proteins which appeared in ventricular tissue of sheep foeti in all age groups under study.","PeriodicalId":13410,"journal":{"name":"Indian Journal of Animal Research","volume":"28 22 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139238179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a mixed-culture farm consisting of Scylla serrata and Peneaus vannamei located in Yunlin Country, Taiwan, were reported mortality cases on culture animals. Methods: Based on clinical signs, histology and molecular analyses, the disease was diagnosed in this study. In the histopathology examination, infected organs, such as the carapace and gills, were stained with hematoxylin and eosin (H and E), then observed under microscope. For the molecular analysis, SalI DNA fragment (WSSV) and spore wall protein (SWP) gene (EHP) were targeted to detected the pathogen in animal host. Result: The cumulative mortality data for this co-infection indicates that S. serrata (1.5% mortality) exhibits higher susceptibility compared to P. vannamei ( greater than 99% mortality). Phylogenetic tree analysis reveals that the spore wall protein (SWP) gene of EHP and the SalI DNA fragment of WSSV strain extracted from S. serrata are genetically similar to those extracted from Peneaus spp., indicating the potential for cross-species infection. Histopathological examination of lesion tissue observed the presence of WSSV basophilic intranuclear inclusion bodies in the carapace tissue and gill fragments of S. serrata. The source of the disease outbreak is highly suspected to be the feed used, which consisted of raw shrimp and fish. This study provides the first documented case of natural EHP infection with co-infection of WSSV in S. serrata.","PeriodicalId":13410,"journal":{"name":"Indian Journal of Animal Research","volume":"21 6","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139250515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The length of postpartum anestrus significantly impacts reproductive efficiency. Apparently enhanced energy attribution to milk production may lead to anestrus by delaying the onset of follicular activity. The absence of an ovulation stimulus, rather than insufficient follicle growth, determines the limited duration until ovulation. The current study was aimed to document the postpartum ovarian dynamics in crossbred Jersey cows. Methods: The study was conducted in ten postpartum crossbred Jersey cows. Transrectal ultrasonography was performed to record the follicular development pattern from parturition till two ovulation or 90 days postpartum on alternate days. The data was analyzed for follicular wave emergence, no of follicular waves, size of the dominant follicle and ovulatory status. Result: Fourty per cent of crossbred Jersey cows showed cyclicity and rest 60 per cent of cows are in anestrum. The mean diameter size of the dominant follicle in ovulated cows is 12.2±1.2 mm and in anestrum cows is 10.6±0.4 mm.

Methods: Present study was conducted to evaluate physical, biochemical and cytological analysis of synovial fluid in apparently healthy stifle joint of young and adult non-descript dogs. Twelve non-descript dogs irrespective of sex were divided into two groups (6 dogs in each group) i.e., group I (2-8 months of age) and group II (1-8 years of age). Dogs died in the OPDs of Veterinary Clinical Complex, Jabalpur were acquired with the consent of pet parent. The duration of study was one year, i.e., from September 2021 to August 2022. Immediately after collection of synovial fluid; volume, colour, viscosity, pH, specific gravity and refractive index were recorded, smear on slides were prepared. Protein and glucose were estimated within one hour using biochemical semi-autoanalyzer. Result: Volume of fluid collected in a single attempt varied from one drop to 0.5 ml.

This paper presents a comprehensive review of the application of machine learning in drone technology for monitoring and analyzing cattle movement patterns.

With the integration of machine learning algorithms, drones offer a cost-effective and efficient solution to monitor large grazing areas accurately. This project will use algorithms to be able to test the viability and possible advantages of merging machine learning and drones for tracking cattle movement, Methods: This study makes use of a dataset of images collected from open data initiatives and crowd-sourced ground truth. Support Vector Machine (SVMs) are one of the machine learning approaches used as a classifier. The encouraging findings demonstrate that if a low precision (10 to 25%) is acceptable, true positive rates in the series of 70 to 85% are feasible.
