				Abstract 
 
				Aim: 
				
				Gastrointestinal parasitism is a serious constraint affecting 
				goat production in the Philippines. This study aimed to 
				determine the prevalence and associated risk factors of 
				gastrointestinal nematode infection in goat-populated barangays 
				of Baybay City, Leyte.  
				Materials and 
				Methods: 
				A total of 81 
				households or farms were interviewed, and 450 goats were sampled 
				for fecalysis. Fecal egg count along with egg morphological 
				identification and coproculture for third stage larvae 
				identification were conducted. Descriptive statistics and 
				logistic regression analyses were carried out to determine the 
				farm- and animal-level prevalence and risk factors.  
				Results:
				
				Fecalysis revealed the presence of strongyle and Trichuris
				spp. with a farm-level prevalence of 100% and 4.94%, 
				respectively; and animal-level prevalence of 96.22% and 4.44%, 
				respectively. The identified strongyle genera per barangay were
				Haemonchus spp. (34.79%), Trichostrongylus spp. 
				(33.29%), Oesophagostomum spp. (24.21%), Cooperia 
				spp. (6.93%), and Chabertia spp. (0.79%). Goats older 
				than 12 months were four times more likely to present high 
				strongyle burden when compared to goats <6 months. With each 
				month increase in goat’s age, the odds of acquiring strongyle 
				infection also increased by 1.07 times. Animals kept in goat 
				house with cemented flooring have lower odds of acquiring 
				strongyle (odds ratio=0.12). Goats raised for leisure purposes 
				and fed with carabao grass (Paspalum conjugatum) were 
				8.12 and 5.52 times more likely to acquire Trichuris, 
				respectively.  
				Conclusion:
				Most 
				of the backyard goat raisers in Baybay City, Leyte, do not 
				practice sound helminth control measures as shown by the high 
				prevalence of gastrointestinal nematodes. The most relevant risk 
				factors for gastrointestinal nematode infection were the age of 
				the goat, type of goat house’s flooring, purpose of raising 
				goats, and feeding practices.
