Météorisation

The word meteorisation means phenomena in two surfaces of activity.

the meteorisation is the swelling of the Abdomen by abnormal accumulation of Gaz.
the meteorisation is the deterioration of the rocks by exposure to the influences of the environment.

Bovine physiology

The meteorisation , or meteorism , is the swelling of the Abdomen by abnormal accumulation of Gaz. This phenomenon is frequent at the Ruminant S, in particular the Bovin S, at which the gases of Fermentation of the Aliment S, in particular the Méthane can accumulate in the paunch.

The causes of the meteorisation at the bovines are multiple. In particular, it can come from a stop of the Rumination for various causes, in the event of fright in particular, of a physical obstacle (obstruction of the esophagus by a foreign body), by the accumulation of foam (spumous meteorisation) following the ingestion of certain plants whose fermentation is accompanied by the abundant production of foam…

The meteorisation can involve the fast Mort animal by Asphyxie because the swelling of the digestive system compresses the lungs. The emergency intervention consists in evacuating gases by trocardage, i.e. by the installation of a Trocart, nozzle posed by the Vétérinaire crossing the abdominal wall.

The Pâturage of Légumineuse S in period of morning Rosée strongly supports the appearance of meteorism at the bovines.

Geomorphological process

The meteorisation gathers the whole of the mechanical, physicochemical or biological processes of elementary reduction of the rocks and minerals on the surface of the Earth. In agreement with the precepts of the climatic geomorphology (Jean Tricart), the variable hierarchisation of these various processes according to the bioclimatic zones would define original meteoric systems, varied, printing their specific signature in the systems morphogenic; freezing would order the morphogenesis of the periglacial areas (gélifraction) and deterioration that of the tropical areas. In short, the wind, the rain and the cold erode the rocks.

Grounds can be formed in the deteriorated rock, it can support the vegetation but vegetable acids constitute an element in the chemical process. The lichen on a rock belongs to the meteorisation which loosens surfaces and prepares the ground for erosion.
