Papilloma in Dogs: Cytomorphological Evaluation and Incidence Analysis of 48 Cases
In a study on cytopathological analysis of samples submitted for tumour diagnosis, papilloma was diagnosed in 48 dogs, which accounted to an incidence of 0.85% of the total tumours diagnosed in dogs during the period. Breed, sex and age wise analysis revealed the highest incidence in non descript and Labrador retrievers, with a male predominance and peak occurrence in the 1–5 year age group. Cytologically, the smears showed individual to clustered neoplastic cells of polyhedral to hexagonal shape resembling normal squamous epithelial cells and characterized by pink to purple cytoplasm and round to oval nuclei which were consistent with papilloma. Histopathology demonstrated classic finger like papillary projections of hyperplastic squamous epithelium overlying a fibrovascular connective tissue core, pronounced spinous (prickle) cell layer hyperplasia and hyperkeratosis with round to oval, vesicular nuclei.
MICROSPORUM CANIS DERMATOPHYTOSIS IN PET DOGS AND CATS IN CHENNAI
The study reports the isolation and identification of the dermatophyte Microsporum canis by mycological culture of skin scabs and hair plucks collected from dogs and cats with dermatological complaints and presented to the Centralized Clinical Laboratory, Madras Veterinary College, Chennai-07. M. canis was successfully isolated from 64 canine and 16 feline patients which accounted to population incidence of 4.31% in canine and 72.72% in feline population. Breed-specific analyses in dogs indicated the highest prevalence in Labrador and non-descript breeds, while sex-based analysis showed a predominance in males, and age-wise distribution revealed a peak in the 1-5 year age group. Similarly, in cats, native Indian breeds, females, and individuals aged 1-5 years exhibited the highest incidence. A notable seasonal trend was observed, with the highest occurrence of M. canis recorded during the summer season in both dogs and cats.
HEMATOLOGICAL AND SERUM BIOCHEMICAL PROFILE OF SAHIWAL DAIRY COW DURING TRANSITIONAL PERIOD
The transition period in dairy cows, encompassing the final weeks of pregnancy through the early stages of lactation, is marked by profound metabolic and physiological changes. This study aimed to evaluate the hematological, biochemical, and metabolic profiles of Sahiwal cows during the transition period in comparison to mid-lactation cows. A total of 24 clinically healthy Sahiwal cows were divided into two groups: Group 1 (transition cows, n = 12) and Group 2 (mid-lactation controls, n = 12). A total of 72 Blood samples were collected at multiple time points from 21 days before calving to 21 days postpartum for hematological, lipid, protein, enzyme, and mineral analyses from group 1 and 12 samples were collected from group 2. Results of the present study indicated significant (P ≤ 0.05) hematological alterations, including reduced white blood cell counts and lymphocyte percentages on the day of calving, along with increased platelet counts. Most of the red blood cell indices (Hb, HCT, MCV, MCH), MCHC, remained within normal physiological ranges. Serum lipid parameters like total cholesterol, triglycerides, HDL-C, LDL-C, and VLDL—declined significantly at calving, reflecting a negative energy balance, and did not return to pre-calving levels even 21 days postpartum. Liver enzymes (AST, ALT, ALP) peaked on the day of calving, possibly due to hepatic stress and muscle damage. Significant reductions in calcium, phosphorus, and magnesium levels were also recorded on the day of calving. Protein metabolism was altered, with reduced total protein and globulin concentrations and increased albumin-to-globulin ratios at parturition. Additionally, elevated levels of blood urea nitrogen and creatinine indicated heightened protein catabolism around calving. In conclusion, the study highlights that Sahiwal cows experience marked metabolic stress during the transition period. These findings underscore the importance of closely monitoring blood biochemical parameters to mitigate health risks and optimize management strategies during this transition period.
A STUDY ON MEDIA PREFERENCES OF NATURAL FARMERS IN REASI DISTT. OF JAMMU &KASHMIR, INDIA
Communication is a crucial aspect of every development facet. The concept of development is particularly significant in the hilly areas, thus, all the stakeholders should converge in order to come up with the best communication strategies to promote development in these areas. Communication for development utilizes all available communication tools including ICTs, traditional tools and the convergence of old and new technologies. In this way, it is innovative and revolutionary [8]:7. Print media provides news on current events and address specific topics in agriculture [21]:52. Farmers preferences of communication should be prioritized to improve agricultural communication and subsequently productivity which is dire in the hilly areas of Jammu and Kashmir in India. In present era, Indian extension system is under immense pressures where the extension workers, have to cater not only vast extension services but also to perform administrative, election, input supply and many other assignments. Under such circumstances, it is not feasible to serve all the farmers, all the time for all the problems when ratio of extension worker and farmer, the sender and receiver is more than 1:1000 in India. Thus, the potential of mass media can be exploited to serve the expanding rural population in this direction. Information plays significant role in our society. Its large scale dissemination through highly preferred communication media constitutes one of the most striking developments. Natural farming has an immense scope in hilly areas of Union Territory of Jammu & Kashmir in India. In order to increase the natural farming in hilly areas, it is necessary that the natural farmers of hilly areas should adopt the standarised natural farming technologies. In order to know the media preferences of natural farmers residing in hilly areas, the present study was conducted in hilly district Reasi of Union Territory of Jammu and Kashmir in India which was selected purposively. A sample of 120 KVK trained natural farmers was selected randomly. A list of different sources of natural farming information was prepared and respondents were asked to indicate their preferences on a three point scale. It was found that Extension Personnel of KVK and Extension Personnel of Agri.Deptt. were highly preferred by the natural farmers followed by the progressive natural farmers of the area.
Effect of Municipal Sludge on Soil Properties and Tree Nutrient Status
The present investigation was carried out to study the nutritional status of soil and tree species using sludge. The research was conducted at Punjab Agricultural University in collaboration with the State Forest and Wildlife Preservation Department at Forest Nursery Baddowal, Ludhiana. Sludge from different sewage treatment plants was used as an organic amend-ment. The main plot treatments included sludge from three sites (Bhattian, Balloke, Jamalpur) and a control (no sludge), and the sub-plots included three forest tree species: Terminalia arjuna (Arjun), Eucalyptus clone 413 (Safeda), and Melia composita (Dek). Different soil macro- (phosphorus, potassium) and micro-nutrients (zinc, iron, manganese), as well as organic carbon, electrical conductivity, pH, and dehydrogenase activity, were ana-lyzed in the soil after twelve months. The Arjun plants led to the highest improvement in soil macro- and micro-nutrient levels when grown with sludge from Bhattian, as compared to sludge from Balloke and Jamalpur. Plant macro- (nitrogen, phosphorus, potassium) and micro-nutrient (zinc, iron, manganese) contents were higher in sludge-treated soils (notably Bhattian) than in the control. Overall, sludge application significantly en-hanced soil fertility and the nutrient uptake of tree seedlings, with Arjun showing the greatest nutrient accumulation among the species.
