Agribusiness Incubators as Catalysts for Fisheries Enterprise Growth: A Performance Analysis
Many agricultural institutes have launched Agri-Business Incubators (ABIs) to foster venture creation in agriculture. This study evaluated the performance of prawn-based enterprises supported by the ABI at ICAR-Central Institute of Fisheries Technology, Cochin. The analysis highlighted the socio-economic characteristics of entrepreneurs graduating from the ABI and examined their product and technological profiles. Findings revealed that most enterprises were in their early stages and required technical and financial assistance for expansion. Technologies such as extrusion and retort packing, provided by the ABI, were widely adopted and underwent an economic feasibility assessment using the breakeven point (BEP) method. The BEP analysis estimated that enterprises became profitable at a production level of 400 units with a total cost of ₹20,000. The relatively low BEP confirmed the suitability of these technologies for small and micro enterprises. The study concluded that entrepreneurs who completed the incubation program achieved higher success rates, regardless of business size. These findings underscore the potential of ABIs as technology enablers in promoting entrepreneurship within the agricultural sector.
Cutaneous Plasma Cell Tumours(cPCTs) in dogs: Clinicopathological diagnosis of 36 cases in Chennai(2015-2024)
Plasma cell tumour(PCT) is a type of round cell tumour occurring in dogs, the other round cell tumours being mast cell tumour, transmissible venereal tumour, lymphoma and histiocytoma. In our study, a total of 36 cases of PCT were diagnosed from cutaneous masses in skin using cytological and histopathological methods. The highest incidence was recorded in Labrador and non-descript breeds, in male dogs, in dogs of age group 5-10 years and in trunk in breed, sex, age and in location wise analysis of tumour occurrence. Cytologic examination revealed abundant round neoplastic cells with distinct cell borders, eccentrically placed nuclei with perinuclear halo and prominent nucleoli. Histopathological examination revealed sheet of pleomorphic round neoplastic cells containing eccentric placed round to oval nuclei along with mitotic figures and multinucleated cells.
PATHOLOGICAL AND EPIDEMIOLOGICAL STUDY OF 524 CASES OF CANINE OCULAR DISORDERS IN CHENNAI
The research work was conducted to record the clinico-morphological attributes and prevalence of spontaneously occurring canine ocular disorders and to acquire comprehensive insights into the cytological, histopathological, cultural, immunohistochemical and hematobiochemical features of diverse ocular disorders in dogs. A total of 524 cases of various ophthalmic disorders were identified in dogs during the study period. In breed-wise occurrence, Shih Tzu breed represented the highest percentage of cases (113 cases, 21.5%) followed by non-descript (110 cases, 20.9%) and Labrador Retrievers (104 cases, 19.84%). In age wise occurrence, 47.5% of the cases were represented by dogs aged between 0-3 years followed by 3-6 years age group accounting for 25.62%. Males were overrepresented (274 cases, 52.79%) than females (245 cases, 47.2%). Bilateral involvement was recorded in 285 cases (54.3%). Unilateral involvement of right eye was recorded in 136 cases (25.9%) and left eye was recorded in 103 cases (19.65%). Intraocular pathological conditions had the highest incidence accounting for 68.12% followed by extraocular pathological conditions accounting for 27.85% and miscellaneous conditions accounting for 3.81%. In anatomic location within the eye, 42.2% cases were associated with the cornea, followed by lens which accounted for 13.1%, followed by third eyelid and eyelid which accounted for 10.8%.
Morphological characterization and Genetic divergence among the Niger (Guizotia abyssinica (L. f) Cass) germplasm
A field experiment was conducted with 114 germplasm to study the morphological characterization using self assumed description and nominal variables of morphological characters, which were used as an input for Nbclust hierarchical cluster analysis in which clustering was done using Ward’s minimum variance method and Euclidean’s method of genetic distance was derived. In this study, niger breeding lines were grouped into six clusters based on analysis of divergence at the genetic distance. They revealed considerable amount of genetic diversity. The largest cluster among all is cluster II. Cluster II has 34 germplasm, cluster I has 29, Cluster III has 24, cluster V contain 13, cluster IV has 9 and cluster VI has 5 germplasm. Whereas, morphological characterization observation were recorded on 12 traits viz., leaf color, leaf shape, leaf serration of margin, leaf angle of branching, stem hairiness, stem color, color of ray florets, plant branching habit, pollen color, seed color, seed shape and seed texture, etc.
Development of digitalized Multimedia Training Module on Integrated Farming Systems for empowering the knowledge level of integrated farmers, VAS and SMS
Ex post facto and experimental research design was followed to document the most prominent integrated farming system model in the study area, the North Western Zone of Tamil Nadu and based on the documented IFS model an interactive multimedia training module was prepared on integrated farming systems to empower the knowledge level of the respondents in the digital era. Focus group interview and key informants’ technique was used to document most prominent and profitable IFS model in the study area. Among the documented IFS models Agricultrue + Dairy + Goat + Vermicompost was selected as the most suitable model and used for the development of an interactive multimedia training module by collecting the content, relevant pictures, images, videos and then developed the module. The present research work was conducted in all the four districts of North Western Zone of Tamil Nadu; two blocks and two villages each from the selected districts and blocks thus forms 8 blocks and 16 villages were selected for the investigation. Ten farmers from each village forms a total of 160 farmers, 10 Veterianry Assistant Surgeons (VAS) from each district and 10 Subject Matter Specialists (SMS) working in Krishi Vigyan Kendra (KVK) and Veterianry University Training and Research Centre (VUTRC) were selected as respondents of this current study. The developed interactive multimedia module was evaluated to assess its effectiveness in empowering the knowledge and utility through a well structured interview schedule. The collected data was subjected to statistical analysis and interpreted.
