Cows with resealable stomach

Another post on cows, this time with some surgical operations done to open a window into their special stomachs.

As a ruminant, a cow's stomach is very different from most mammals. It consists of 4 chambers: the rumen, reticulum, omasum, and the obamasum (true stomach).

Although the surgical operation to have a resealable window in the cow's stomach seems cruel, this treatment is vital for us to understand better on the digestion of cellulose. The stomach content can be analysed from time to time to mark the progression of cellulose digestion.
