When a goat dies from bloat, it's primarily due to the severe pressure build-up in the rumen that compromises its ability to breathe.
The Progression of Death from Bloat
Bloat, the excessive accumulation of gas in the rumen (the first stomach compartment of a goat), can lead to a rapid and distressing death if not treated promptly. Here's a breakdown of what happens:
- Rumen Distention: The rumen becomes severely distended with gas.
- Respiratory Distress: The expanding rumen presses against the diaphragm and lungs, making it increasingly difficult for the goat to breathe. This is similar to the reference's mention of pressure on the lungs hindering breathing.
- Reduced Oxygen Intake: As breathing becomes labored, the goat's oxygen intake decreases significantly.
- Organ Failure: The lack of oxygen begins to affect vital organs, including the heart and brain.
- Circulatory Collapse: The pressure on the large vessels can impede circulation, further depriving the organs of oxygen.
- Death: Ultimately, the combination of respiratory failure, oxygen deprivation, and circulatory collapse leads to death, sometimes within a matter of hours if the bloat is severe and untreated.
Contributing Factors
The speed and severity of death depend on several factors:
- Type of Bloat: Frothy bloat (caused by rapidly fermentable feeds) is generally more dangerous and faster-acting than free-gas bloat.
- Severity of Bloat: The amount of gas accumulation directly impacts the pressure on the respiratory system.
- Overall Health of the Goat: Weaker or already compromised goats are less likely to survive a severe bloat episode.
- Speed of Intervention: Prompt treatment, such as using a bloat drench or, in severe cases, trocarization (puncturing the rumen to release gas), is crucial for survival. The reference suggests positioning the goat with its front legs elevated to help relieve lung pressure.
