Prevalence and intensity of nodular oesophagostomosis in West African Long Legged goats in Northern Benin

Abstract

This study was conducted between January and December, 2011 to assess the prevalence and intensity of nodular lesions caused by Oesophagostomum species into the intestine of Benin goats. Intestines of 384 West African Long Legged (WALL) goats, from Northern Benin, were examined during slaughter, and 241 intestines (62.8%) were found to be positive for nodular lesions. The infection rate was significantly (p < 0.05) higher during the rainy season in comparison with dry season. Animals above one year of ages were mostly affected (82.5%). Extensive lesions were observed in 95 large intestines (24.9%) and calcified nodules were observed in 130 intestines (34%).
