Abstract
The Present study was conducted in the Division of Veterinary Pathology, F.V.Sc and A.H, Jammu from the month of January, 2016 to January, 2017 and samples were collected from TVCC, F.V.Sc & AH., SKUAST-J, R.S. Pura and CVH, Talab Tillo, Jammu. Out of 55 collected samples, 44 cases were confirmed to be Neoplastic in origin and remaining 11 cases were found to be non neoplastic conditions. The incidence of nonplastic conditions was studied on the basis of age, sex, system wise and classified and diagnosed on the basis of gross and histopathological examination and AgNOR counts. The overall occurrences of animal neoplasm were 80% comprising of 36.36% benign and 63.64% malignant tumours. The occurrence of neoplasms in canines and bovines was 79.31% (23/29) and 80.76% (21/26), respectively. In canines, the highest risk of development was observed at the age group pf 10-12 years and lowest at 0-3 years of age group in both sexes. However, in bovines, highest risk of development was observed at the age group of 0-3 years and lowest at 15 years and above age group animals. In both species of animals, the frequency of neoplastic conditions and malignancy was more in female than male animals. In canines, tumour of skin and soft tissues showed highest occurrence (56.52%) followed by mammary gland (26.08%), genital system (8.70%), bone (4.35%) and lymphoid organ (4.35%). In bovines, skin and soft tissues showed highest occurrence (52.38%) followed by eye (33.33%), mammary gland (9.52%) and the tumour of alimentary system (4.77%). In canines, one each case of bone (i.e. osteosarcoma) and spleen (i.e. splenic lymphoma) was observed. Among the genital system, one each case of tumour of male genial organ i.e. sertoli cell tumour and female germinal organ i.e. ovarian adenocarcinoma was observed. Non case of bone, spleen and germinal system of bovine was recorded in the present study. Among mammary gland tumours, 6 cases in canines and two cases in bovines was observed. In bovines, one case of equlis and 6 cases of ocular squamous cell carcinoma the second highest number of tumour after skin and soft tissues was observed.
