Some farmers have reduced burping in their cows by feeding them alfalfa and flaxseed, which are closer to the grasses that they had eaten in the wild before they were domesticated.The failure to burp successfully can be fatal. This is particularly common among domesticated ruminants that are allowed to gorge themselves on spring clover or alfalfa. The condition, known as ruminal tympany, is a high-pressure buildup of gas in the stomach(s) and requires immediate treatment to expel the gas, usually the insertion of a flexible rubber hose down the esophagus, or in extreme cases the lancing of the animals side with a trochar and cannula. Birds
There is no documented evidence that birds burp, though ornithologists believe that there is nothing which physiologically prevents them from doing so. However, since the microbiota of birds do not include the same set of gas-producing bacteria that mammals have to aid in digestion, gas rarely builds up in the gastrointestinal tracts of birds.

The parents of an individual with an autosomal recessive disorder both carry one copy of the defective gene, but usually do not experience any signs or symptoms of the disorder. Currently, no specific mutation in any gene has been found to cause the disorder.It appears that the gene inositol polyphosphate phosphatase-like 1 is the cause of this condition in at least some cases. Diagnosis
Epidemiology
Opsismodysplasia is a very rare disorder, and is estimated to occur in less than 1 in 1,000,000 people. History
The disorder was first described by Jonathan Zonana and associates in 1977. Further observation of four cases of it was reported by Pierre Maroteaux and colleagues in 1982, and Maroteaux was the first to call the disorder "opsismodysplasia", in a 1984 journal report of three affected individuals. The name derives from the Greek opsismos, meaning "late", while the term dysplasia refers to development. References
