Studies on Kinetics of Ciliates Inhabited in Stomach of Korean Native Cattle



Abstract
In order to observe the kinetic of ciliates inhabited in the stomach, investigation of the content juice in the stomach was carried out on the 30 Korean native cattle, selected as healthy ones and slaughtered at Jeonju abattoir in August, 1974.
The following is a brief summary of the leading facts gained through the experiment.
1. The average pH of the content juice showed 6.567±0.056(SE) in the rumen, 6.607±0.053 in the reticulum, 6.183±0.056 in the omasum and 2.627±0.061 in the abomasum.
2. The presumed number of ciliates per ㎖ was calculated 168,200±17,035(SE) in the rumen, 173,200±19,728 in the reticulum, 23.600±3.537 in the omasum and 467±266 in the abomasum.
3. In the content juice the number of ciliates was gradually slowed down, the pH decreased from rumen to abomasum and the changes were denoted by quadratic curves(parabolas).
4. In accordance with the increase of the number of ciliates the pall also becomes higher and in this situation the correlation coefficient was γ_(xy)=0.508.
5. Population density of ciliates was checked and Entodinium showed 60 per cent among them, but Polyplastron was figured only from 0 to 0.05 per cent.
6. Among 26 species of ciliates which were identified from the content juice, Entodinium simplex was showed the highest population density, raging from 40 to 50 per cent, Dasytricha ruminantium was neat to it, Eudiplodinium affine after the next, and Entodinium caudatum and Eudiplodinium maggi were also found abundantly in the abomasum.
