They claim for decades, researchers have artificially created fistulas (also known as cannulas) in ruminant animals such as cows, sheep and deer. These are essentially window-like holes in the side of an animal’s body.
They claim there is evidence of fistulated cows on Lincoln’s campus.
The ODT quotes a Lincoln University spokesperson as saying fistulated cows were used for research into rumen digestibility.
The research is approved by the Lincoln University Animal Ethics Committee.
