Ruminitis
The Ruminitis is an inflammation of the mucous membrane of the rumen ( rumen ) in ruminants .
causes
Ruminitis is usually non-infectious. More common causes are
- a shift in the pH value into the acidic range ( rumen acidosis ),
- Absorption of chemically damaging substances from disinfectants ( formalin , copper sulfate ) or fertilizers ,
- Ingestion of hot feed ( stillage ).
If the mucous membrane has been damaged beforehand , it can also be caused by various bacteria ( Arcanobacterium pyogenes , Fusobacterium necrophorum ). Finally, ruminitis is possible as a side effect of some viral diseases ( foot and mouth disease , malignant catarrhal fever ).
clinic
An acute Ruminitis manifests itself with loss of appetite, reduced rumen motor function , pain in the abdominal area and poisoning. In chronic cases the feed intake fluctuates, the rumen motor is reduced and there are Aufgasungen ( Pansentympanie ), diarrhea and an increasing emaciation. Bacteria can pass through the damaged rumen epithelium via the portal vein and reach the liver and cause liver abscesses .
The diagnosis is usually only possible through a preliminary report or a surgical opening of the rumen (ruminotomy), in which inflammatory changes in the mucous membrane areas can be detected.
therapy
For therapy, agents that envelop the mucous membrane ( linseed mucus , oat gruel ) are administered via a nasopharyngeal tube. Antibiotics can be given to prevent general bacterial infections or liver abscesses . In addition, the treatment of any existing rumen acidosis, i.e. eliminating the cause, is necessary. By dietary may measures (Hay, reduction of the concentrate feeding) a mucous membrane irritation caused by acidic pH-values is reduced.
