Abomasal bloat associated with the Sarcina genus of bacteria is a rare disease reported in young ruminants such as calves (EDWARDS et al., 2008), lambs (VATN et al., 2000; EDWARDS et al., 2008) and kids (DEBEY et al., 1996).
In a previous study, 67 lambs with abomasal disease (abomasal bloat or rupture) and 45 healthy lambs were analyzed histopathologically, and the study found bacteria of the Sarcina genus in the abomasum of 53 lambs with abomasal disease and the absence of this bacteria in the abomasum of healthy lambs, demonstrating a possible causal association between bacteria from the Sarcina genus and gas accumulation in the abomasum.
(2007) during abomasal bloat in young ruminants fed with an ad libitum feeding system that resulted in the consumption of great quantities of fermentable foods.
