Question:

Given below are two statements:
Statement (I): The ruminal and reticulorumen movements are not affected in acute local peritonitis of cattle.
Statement (II): The cattle feel pain during urination and defecation in acute local peritonitis.
In light of the above statements, choose the most appropriate answer from the options given below:

Show Hint

Any inflammatory condition affecting the peritoneum or abdominal organs in ruminants will cause reflex ruminal stasis (reduced motility) and pain during activities that increase abdominal pressure, such as defecation or coughing.
  • Both Statement (I) and Statement (II) are true.
  • Both Statement (I) and Statement (II) are false.
  • Statement (I) is true but Statement (II) is false.
  • Statement (I) is false but Statement (II) is true.

The Correct Option is D

Solution and Explanation

Step 1: Understanding the Concept:
Local peritonitis in cattle is most commonly a sequela of Traumatic Reticuloperitonitis (TRP or hardware disease), where a foreign metallic object penetrates the reticulum wall, causing localized inflammation of the peritoneum.

Step 2: Detailed Explanation:

Let us evaluate both statements:
- Statement (I): In acute local peritonitis, the localized inflammation and associated pain cause reflex inhibition of the forestomach motility. This leads to a significant decrease in or complete absence of reticulorumen movements (ruminal stasis). Therefore, stating that reticulorumen movements are not affected is incorrect. Thus, Statement (I) is false.
- Statement (II): Urination and defecation require voluntary contraction of the abdominal muscles (abdominal press), which increases intra-abdominal pressure. In animals with acute peritonitis, this increase in pressure stretches the inflamed, sensitive peritoneal membranes, causing acute pain. Consequently, affected cattle will show signs of pain, such as grunting, arching the back, or treading, during these activities. Thus, Statement (II) is true.
Therefore, Statement (I) is false but Statement (II) is true.

Step 3: Final Answer:

Statement (I) is false but Statement (II) is true, which corresponds to option (D).
