By Anna Hopkins For Dailymail. On a bright, sunny morning in the summer of , Ron and Paula Watson, two farmers in Springfield, Missouri, witnessed something that changed their lives forever. They said they saw a 'green, cone-shaped craft' — next to which two 'silver little beings' were standing over a large black cow. What are they doing to it? But it just laid there and it didn't move.
Compared to other farm species, the pig appears to be particularly vulnerable to prolapse of the rectal tissue through the anus, which can be seen in any age group from as early as days old up to adults. The fundamental cause of the prolapse is an increase in abdominal pressure, forcing a breakdown in the weak muscular support mechanism of the pelvis, which normally retains the rectum in place. There may well be both breed and gender differences in the vulnerability of individuals to prolapse occurring. The following list provides an outline of the most common causes of prolapse, as seen in commercial pig farms

The animal was pulled out of the well and treated with antibiotic and anti-inflammatory injections by a field veterinarian, who also manipulated and tried to reposition the intestines that had prolapsed per rectum. Subsequently, while straining for rectal evacuation, the animal caused the intestines to prolapse again. On clinical examination, the animal was standing and walking without any signs of lameness or spinal cord injury.
The Oesophagus The oesophagus is a muscular tube that connects the mouth with the forestomach. Food passes down the oesophagus by contraction of the muscles in the walls that push the food along in a series of waves called peristalsis. The ruminant oesophagus is also capable of reversed peristalsis or antiperistalsis.
