Cryptosporidiosis is predominant in piglets and other young farm animals and the infection can be severe resulting in financial loss to producers. Faecal samples from one hundred and thirty-two piglets were examined for Cryptosporidiumoocysts using formol-ether concentration method and modified Ziehl-Neelsen staining technique. Cryptosporidium oocysts were found in 18(13.6%) of the faecal samples and the prevalence were higher among males (20.0%) than females (5.3%), younger (19.0%) than older (8.7%) piglets, piglets raised under intensive (16.7%) than from under semi-intensive/extensive systems (0%), piglets with loose faeces (28.6%) than from well formed faeces(10.8%) and piglets that drank bore hole water (13.8%) than from those that drank well water (13.3%). There were associations between prevalence of Cryptosporidium oocysts and sex of piglets (OR = 0.22; 95% CI on OR: 0.05 < OR < 0.88), faecal consistencies (OR = 3.30; 95% CI on OR: 0.93 < OR < 11.47) and management systems (P < 0.05). On the other hand, there was no association between prevalence of Cryptosporidiumoocysts and type of water and age of the piglets (P > 0.05). This study shows that sex, faecal consistencies and management systems influence the prevalence ofCryptosporidium oocysts in faeces of piglets in Kaduna metropolis.
Key words: Cryptosporidium, piglets, faeces.
