Online published on 15 March, 2019. Abstract Bovine cryptosporidiosisis primarily associated with neonatal diarrhoea with higher morbidity than mortality in young calves till they attain immunological maturity. The present investigation relates to a report on the shedding of Cryptosporidium oocyst intwo buffalocalvesof buffalo farm, Lala LajpatRai University of Veterinary and Animal Sciences, Hisarfrom 1st days up to 3 month of age at 15 days interval using simple conventional microscopy. By using formol-ether concentration technique followed by modified Ziehl-Neelsen (ZN) acid fast staining, Cryptosporidium oocysts were concentrated and identified. The Cryptosporidium oocysts appeared as reddish pink coloured bodies against a bluish/greenish coloured background at oil immersion using ZN staining kit. The maximum oocyst shedding was observed (2.3 oocyst/field) during 16 to 30 days of age. The oocyst shedding gradually decreased with increase in age afterwards clearly indicating the disease of young buffalo calves.
