Abstract:
The present study was conducted in 117 bovine cases suspected for neoplasia, including 114 cattle and 3 buffaloes. Data about the animal including history, clinical signs, nutritional status, type of husbandry, climatic conditions, age, sex and breed were collected. The size, location, shape, colour and any changes related to the tumours were recorded. The highest incidence of ocular tumours was recorded in 3 to 6 years age group followed by 7 to 10 years and in Holstein Friesian crossbred followed by Jersey crossbred cattle. The highest occurrence was noticed in females and the highest incidence was recorded during the summer season. The maximum number of tumours was found located in the third eyelid followed by whole eye involvement. The occurrence of ocular tumours was more in the left eye and in the animals reared under semi-intensive management system and allowed for grazing. The findings in the present work suggest a multifactorial etiology to ocular neoplasms.
