BACKGROUND: The predisposition of ruminants to indigestible foreign materials is becoming a major global concern in livestock systems in developing countries making gastrointestinal tract impactions severe veterinary emergencies. OBJECTIVES: This study aimed to investigate the prevalence and types of indigestible foreign material impactions in small ruminants in Gombe state, Nigeria. METHODS: A total of 940 goats and 790 sheep were selected through a systematic random sampling technique and antemortem examinations were completed before slaughter at major abattoirs in Gombe state. The gender, age, and body condition score (BCS) of animals were recorded. Post-mortem examination of the rumen and reticulum was performed and foreign materials in the abdominal cavity were removed, identified, and recorded. RESULTS: Out of 1730 examined small ruminants, 1167 (67.46%) were found to have various types of indigestible foreign materials in their gastrointestinal tracts. The frequency was significantly (χ2=58.047, P<0.0001) higher in goats (38%) than sheep (23.7%). Prevalence rates of 13.6%, 12.9%, 12.1%, 11.8%, and 11.4% were recorded in Gombe, Yamaltu Deba, Akko, Funakaye, and Kwami Local Government Areas, respectively. Prevalence was found to be significantly (P<0.0001; χ2=732.87; OR=47.009) higher in adult (59.6%) than young (2.1%) cases, significantly (P<0.0001; χ2=637.61; OR=31.145) higher in females (42.5%) than males (19.2%), higher in goats (χ2=177.03, P<0.0001) and sheep (χ2=191.39, P<0.0001) with poor BCS than those with medium and good BCS. Significantly higher proportions of indigestible foreign materials were recovered in the rumen of goats and sheep, compared to the reticulum. Plastic was the most commonly encountered indigestible foreign material in goats and sheep, followed by seed/nuts, ropes, and clothes. CONCLUSIONS: The results of the current study revealed a prevalence of 67.46% for indigestible foreign materials in goats and sheep. Predisposing factors to indigestible foreign materials in ruminants in the study area included the lack of adequate plastic waste disposal system and management system, as well as the free grazing of livestock. Therefore, it was recommended that collaborative intervention schemes involving governmental agencies and livestock farmers be incorporated to increase public awareness about the proper disposal of domestic waste.
