Bloat (Ruminal tympany) in Ruminants

Description
Bloat in ruminants can be frothy bloat associated with legumes or grain feeding, or free gas bloat. Bloat – gorging on anything unsuitable such as wet grass pastures or after raiding food bin. Excessive accumulation of gases in the rumen, the first stomach of a cud-chewing animal. Bloat is probably formed to a large extent by bacterial action. It occurs in all ruminants, but is most common in cattle; it appears typically in animals that graze on newly developed, highly productive, lush green pastures, especially during a wet summer on clover-dominant pastures. Bloat can result from excess frothiness of the ruminal ingesta or loss of tone and motility of the rumen. Both of these conditions will prevent the normal eructation process. Treatment consists of passing a tube to the stomach or of reducing the foam formation by oral administration of mineral or vegetable oils. Prevention is attempted by carefully controlled management practices, administration of antibiotics, and the use of nontoxic oils.

Additional information


Bloat in ruminants can be frothy bloat associated with legumes or grain feeding, or free gas bloat. Bloat – gorging on anything unsuitable such as wet grass pastures or after raiding food bin. Bloat is an overdistention of the rumenoreticulum with the gases of fermentation, either in the form of a persistent foam mixed with the ruminal contents—called primary or frothy bloat, or in the form of free gas separated from the ingesta—called secondary or free-gas bloat. It is predominantly a disorder of cattle but may also be seen in sheep. The susceptibility of individual cattle to bloat varies and is genetically determined.
