Here's why:
* Location: The left paralumbar fossa is a natural depression located on the left side of the cow's abdomen, just behind the last rib. This area is relatively superficial, making it easier to access the rumen.
* Rumen Position: The rumen, the largest compartment of the cow's stomach, occupies the majority of the left side of the abdominal cavity.
* Minimizing Risk: This location allows for a surgical approach that avoids major blood vessels and other important organs.
The specific surgical procedure is called a rumenostomy, which involves making an incision in the rumen wall and attaching a cannula (tube) to create a permanent access point. This procedure is usually performed to treat chronic rumen problems or to collect samples for diagnostic purposes.
