Everything about the Abomasum totally explained
The
abomasum, also known as the
maw, and the
rennet-bag, is the fourth and final
stomach compartment in
ruminants. The normal anatomical location is along ventral midline. It is a
secretory stomach similar in
anatomy and function as the
monogastric stomach. It serves primarily in the
acid hydrolysis of
microbial and dietary
protein, preparing these protein sources for further
digestion and
absorption in the
small intestine.
Dairy cattle on high production diets are susceptible to a number of pathologies, most commonly after calving. A gas filled abomasum can move into an abnormal location resulting in left displaced abomasum (LDA) or right displaced abomasum (RDA). If the abomasum displaces to the right, it's at risk of torsion and becoming a right torsioned abomasum (RTA). A displaced abomasum will cause cows to present all or some of the following signs: loss of appetite, decrease rumen contractions, decrease cud chewing, and drop in milk production. While an LDA and RDA are not immediately life threatening, veterinary care is required for surgical correction.
It secretes
rennet, an ingredient used in cheese creation.
The word abomasum is from
New Latin and it was first used in
English in 1706. It comes from
Latin ab- +
omasum "
intestine of an
ox," and it's possibly from the
Gaulish language.
