Awww…. The annual cowboy serenade..
Yesterday was weaning day and they sang all night.
It will be a few more days (and nights) of concerts ahead.

Finding balloons in my pastures is aggravating. Wildlife and livestock can die because of choking on these things.
I wish there was a way to track who releases them. People should be held financially responsible when their balloons kill something.
I pulled a long ribbon out of one of my momma cow’s mouth this spring.
There has been enough outcry for this to stop. I don’t think I would believe anyone that claimed ignorance.

🗞This diagram explains the mechanism of fever in a cow, especially in response to an infection like mastitis. 🐄

🧾Step-by-step Explanation:

1. Pathogen Entry (e.g., Mastitis)
- A pathogen causes mastitis (infection of the udder).
- This triggers the immune system to release pyrogenic cytokines (like IL-1, IL-6, TNF-α).

2. Cytokines Travel to Brain
- These cytokines enter the bloodstream and reach the hypothalamus in the brain.
- In parallel, sensory nerves from the warm receptors in the body (red line) carry signals to the
dorsal horn of the spinal cord and up to the brain.

3. Hypothalamic Response
- The cytokines stimulate PGE2 (Prostaglandin E2) production in the hypothalamus.
- PGE2 resets the body’s thermostat in the preoptic area (POA) and MnPO of the hypothalamus.

4. Fever Generation
- The brain now perceives the current body temperature as too low, and triggers heat-producing responses.
- Result: Fever is generated.

5. Effector Mechanisms to Reduce Heat
- Once infection is controlled or when cooling is needed, the body uses:
- Sweating (via sweat glands)
- Vasodilation (widening of blood vessels in skin)

🖋These are efferent pathways to dissipate heat and return body temperature to normal.
