Abstract

The aim of the study was to investigate the prevalence and associated risk factors of Gastrointestinal (GI) parasite in Cattle through semi-intensive rearing system at BAPARD campus during the period from July 2019 to June, 2020. A total of 156 samples from 39 cattle among these, 29 Bulls and 10 heifers were collected at the time of defecation or just after defecation. Samples were collected every three months of a year to find out the effect of season. All cattle are Holstein crossbred. The collected Feces samples were examined by direct smear method followed by McMaster counting technique under microscope for detection the morphology of egg at BAPARD Parasitology Lab on the day of collection. The overall prevalence of GI parasite was 26.72% and more frequent in more frequent in rainy season (57.14%) followed by summer (28.57%) and winter season (14.29%). The parasitic prevalence load was low in winter season. In endoparasitic infection, the higher prevalence of Paramphistomum spp. (19.05%) was found in rainy season followed by Haemonchus spp. (9.52%); Fasciola spp.(4.76%), Schistosoma spp. (4.76%) and Toxocara spp. (4.76%). In cattle, prevalence of Paramphistomum spp. (15.38%), Schistososma spp (3.85%) and Haemonchus spp. (7.69%) was higher in adult cattle (above 2 year) comparatively growing and young, whereas prevalence of Toxocara spp. (3.33%) was higher in young (1-1.5 year) than growing and adult cattle. In other case Female (27.5%) are slightly higher than male (26.72%) cattle.
