Ruminant Digestive System
In general, the flow of the process of
digestion of human food and ruminant
animals (breeding anchors) are not much
different. Difference lies only in the
arrangement of the teeth and the structure of
the stomach alone. The digestive tools of
ruminant animals include the oral cavity,
esophagus, stomach, small intestine, colon
anus. Food enters the first time through
and
the oral cavity. Inside oral cavity, food is
chewed by teeth and mixed with water
saliva. The teeth have an arrangement of
16 incisors that serve as food tongs; 12 Figure 15. Tooth structure ruminant animals
pieces of front molars (premolars) and 12
back molars (molars) that serve to camp
food.
Meanwhile, the canines have been modified to bite and cut plants. Between the
incisors and molars there is a gap called diastema. Its function is as a place to
stick out the tongue when picking up plants or leaves. Note Figure 15.
From the oral cavity, food enters through the esophagus towards the stomach.
The stomach of ruminants like a cow and goats are different from human
stomachs. The ruminant stomach is divided into four parts, namely the rumen,
reticulum, omasum, and abomasum. Note Figure 16.
