Students at the Chicago High School for Agricultural Sciences in Mount Greenwood can now 'see inside' a cow to help them study biology.
The three-year-old cow is surgically fitted with a cannula, a port used to study its stomach contents, that will be opened in a couple weeks and allow students to look inside and even reach in with sanitary gloves to feel the stomach.
"You can actually see the function of the stomach," Samantha Kujawa, an animal science teacher at the school said. "You can see what she is eating and what she has eaten. You can feel the inside of her rumen."
