Three hundred and sixty intestinal samples were examined at necropsy for gastrointestinal nematode parasites of black Bengal goats of Sirajgong district of Bangladesh. Results showed that among various nematode parasites recovered were Haemonchus contortus (67.45 %), Oesophagostomum columbianum (43.27 %) and Gaigeria pachyscelis (41.85 %). Among other nematode parasites Trichuris ovis (28.35 %) and Bunostomum trignocephalum (18.25 %) were found. The seasonal variation in nematode infection was determined by monitoring faecal egg counts of 2138 goats during the same period. The mean egg per gram (epg) of faeces was found to maintain high level during October and November that reached the peak in November at post rainy season.
