Cows Are Way More Intelligent Than You Probably Thought
When we think about our most intelligent friends in the animal kingdom, species like orangutans, dolphins, elephants and octopuses are likely to come to mind.
Dairy cows probably don’t make the list. But research, including a new study conducted by an undergraduate student in Australia, suggests these farm animals may be smarter than we give them credit for.
Alexandra Green, a 21-year-old student at the University of Sydney, developed a test that provides evidence of cows’ sophisticated cognitive abilities. Green found that dairy cows could follow sound through a maze in order to find food, suggesting heightened executive function and decision-making abilities.
These capabilities shouldn’t be surprising to us, says zoologist Dr. Daniel Weary, a professor in the Animal Welfare Program at the University of British Columbia.
“These are highly developed mammals that have been solving problems for a long, long time,” he told The Huffington Post. “If anything, it reflects poorly on us that we’re surprised that these animals are smart. Of course these animals are smart.”
Mastering the maze
For the experiment, Green trained six dairy cows to navigate a large T-shaped maze modeled after smaller mazes used on mice and rats. The cows were trained to follow sound through the maze in order to get to their food.
Four out of the six heifers nailed the test, while the other two scored 75 percent. One cow was able to find the food in under 20 seconds on the first day of learning the maze, suggesting intelligence levels can vary widely between animals.
“They would turn their heads to where the sound was,” Green told New Zealand Farmer. “They would really think about it, whereas in the beginning they were making a guess.”
The findings may have some important implications for the cattle industry, Cameron —> Read More
