Two hundred and thirty six grasscutters were investigated in captivity to identify the common features and ailment responsible for mortality. The study covered a period of ten years (2003 to 2013). The highest mortality percentage (51.72%) was recorded in 2004, while 8.33% recorded in 2010 was the lowest. Causes of mortality in the unit include: pneumonia, traumatic injuries, cannibalism, respiratory tract infection, bloat, paralysis of the neck, neck swelling, worm infestation and forced weaning. Pneumonia ranked highest among the causes of mortality in the unit. This was followed by mortality as a result of traumatic injuries. The lowest cause of mortality was forced weaning. Also, across the sexes, the number of female grasscutters affected was higher than that of the male. In 2012, the percentage mortality of both sexes was the same at 50%. However, some grasscutters died of unidentified causes.
