CASE REPORT: A NEW FACTOR OF RUMEN BLOAT IN GOATS AFTER THE COVID-19 PANDEMIC

Goats may suffer from rumen bloat for many reasons, e.g. improperly concentrated ratio or obstruction. The disease can be caused by eating undigested items, e.g. plastic rope or bags. Since the COVID-19 pandemic, it has often become mandatory for people to wear medical masks. People are generally unaware that masks left on the ground pose a risk to goats who may eat them. This case report describes the rumen bloat caused by medical masks in a male goat reared in an elementary school. After physical examination, the goat showed a bloated rumen, anorexia, depression, and weakness. The heart rate was normal, but respiratory patterns were fast and deep. Fewer defecated feces were noted by the owner. Furthermore, the owner’s complaints and ultrasound images revealed that undigested items in the rumen were the cause. After performing a standard rumenotomy, we scooped out four medical masks, one plastic bag, and one high-density nylon rope from the rumen. We believe this was the first report describing the risk of medical masks in goats. Promoting life and animal welfare education is essential to inform others of the harm medical masks pose to animals.
