Gastrointestinal Helminths in Local (Black Bengal) and Jamunapari Goats of Barishal Sadar, Southern Bangladesh

Abstract

Gastrointestinal helminths are important causes of hindering global goat production. To find the prevalence of gastrointestinal helminths of Black Bengal and Jamunapari breeds of goats, the current investigation was carried out at Barishal Sadar Upazilla of Barishal district, Bangladesh. The gastrointestinal helminths were identified through coprological examination. A total of 112 fecal samples were collected from household goats across different seasons, breeds, sexes, and ages. During the study period, four types of gastrointestinal helminths were identified based on the presence of helminth eggs in fecal samples. The overall prevalence of gastrointestinal helminths in goats was found to be 82.1%, while the prevalence rates of Fasciola gigantica (F. gigantica), Paramphistomum spp., Bunostomum spp., and Hemonchus spp. were 34.8% (95% CI: 1.4-2.5), 22.3% (95% CI: 0.7-1.8), 14.3% (95% CI: 0.1-1.5), and 10.7% (95% CI: 0.2-1.0), respectively. A significantly different prevalence was observed among different gastrointestinal helminths in goats. A significantly lower prevalence of F. gigantica and Paramphistomum spp. was observed in male goats, compared to females. A higher prevalence of F. gigantica was significantly observed during the winter, compared to the summer. The current study elucidates that F. gigantica was more prevalent in female goats. The current study indicated that F. gigantica was more prevalent in female goats. These findings underscore the importance of further research and control measures to manage gastrointestinal helminth infections in goats across southern Bangladesh and other regions with similar environmental conditions.
