Acute necrotising pancreatitis following grain overload in a donkey.

This research study looks at a case where a donkey developed severe abdominal pain and heart failure 24-36 hours after eating a large quantity of poultry feed. The donkey was euthanized, with post-mortem examination revealing severe pancreas inflammation (acute necrotising pancreatitis) due to the excessive grain consumption.

Donkey’s Initial Condition and Findings

• The donkey under study began displaying symptoms of severe abdominal pain, bloating, and even cardiovascular collapse within 24 to 36 hours of eating a large quantity of poultry feed. This feed is particularly rich in grain and other materials that could cause grain overload in the donkey.
• In addition to these symptoms, the donkey was also found to be experiencing gastric reflux, a condition in which the stomach’s contents come back up into the food pipe.

Laparotomy and Post-Mortem Findings

• Due to the severity of the symptoms, the donkey was subjected to a surgical procedure known as a laparotomy. This procedure, involving an incision into the abdominal cavity, revealed several unusual conditions: the donkey’s stomach was exceedingly dilated, the small intestine was inactive and empty, stool in the colon was dry, and the cecum (a part of the large intestine) was oddly positioned.
• These findings, however, did not align with the extremity of the donkey’s symptoms which were believed to be due to endotoxemia, a potentially fatal condition that involves the presence of endotoxins (toxins released from the cell wall of a dying or dead bacterium) in the blood.
• The donkey had to be euthanized due to the severity of its condition. A post-mortem examination then found that the donkey was suffering from acute necrotizing pancreatitis: a rapidly progressing inflammation of the pancreas that was causing the tissue to die off. This potentially fatal condition was paired with massive stomach dilation and clogging of the donkey’s right dorsal colon.

Link Between Overeating Grains and Acute Equine Pancreatitis

• This study makes a significant stride in acknowledging the connection between grain overload, a condition often seen in horses (equines) due to excessive consumption of grain, and acute pancreatitis in such animals.
• This is particularly important given the potential fatality of pancreatitis, a condition that is often hard to diagnose and treat in the early stages, especially given that symptoms might not align with the severity of the condition, as was the case with the donkey under study.
