Gastrointestinal nematodes are one of the main constraints to goat production worldwide. A cross-sectional study longitudinal study from were conducted in Haramaya, Ethiopia to determining the prevalence and seasonal dynamics of gastrointestinal nematodes of goats. A total of 384 fecal samples were randomly collected and analyzed using standard parasitological methods of floatation and ova culture. The overall prevalence of gastrointestinal nematodes was 73.7% (283/384). The result showed higher percentage prevalence in young (76.2%) than adult’s age group (73.0%). The difference in gastrointestinal nematode infection between female (79.6%) and male goats (59.09%) was statistically significant (p=0.001). The Egg Per Gram (EPG) count result showed 69.6%, 7.4%, 23.0% of the goats were lightly, moderately and heavily infected with gastrointestinal nematodes respectively. The overall genera of nematode identified and counted from coproculture in the study areas were trichostrongylus spp (54.6%), teladorsagia (17.6%), haemonchus spp (14.4%), muellerius capillaris (7.6%), oesophagostomum spp. (1.7%), nematodirus spp (1.7%), strongyloides papillosus and cooperia (0.9%), chabertia (0.5%) and trichuris (0.1%). Based on the monthly mean EPG count recorded during the short and long rain seasons with peaks occurring in may and september of the year. To mitigate the burden of gastrointestinal nematode parasites: Good management practices considering breed, sex, age, pasture rotation, housing of animals during peak time and optimizing anthemintic usage through deworming of goats during season where parasitic load is peak in host animal is very crucial.
