50 free Cows trivia questions with answers. Cows are the most-farmed large animal on Earth, and almost everything about them is stranger than it looks: a stomach with four compartments, a field of view that wraps nearly all the way round, a wild ancestor that only went extinct in the 1600s, and a public-relations career that stretches from Elsie the Borden cow to the Chick-fil-A billboard herd. This quiz mixes plenty of gentle questions for kids and families (what is a heifer, what did the cow jump over) with genuinely hard ones about breeds, dairy science, cattle terminology, records and cows in mythology. Play it solo, or read the questions aloud for a farm-day, classroom or pub round. Every answer was checked against a primary source, mostly Wikipedia's cattle and breed articles, Guinness World Records and official pages, and each question shows its citation, so you can trust the answers when someone at the table disagrees.

Q 01How many compartments does a cow's stomach have?
Four
The compartments are the rumen, reticulum, omasum and abomasum, and the whole thing counts as a single stomach.
Q 02Which compartment of a cow's stomach is known as the "true stomach", the equivalent of a human's?
Abomasum
The rumen does the heavy lifting as a fermentation vat full of microbes, but only the abomasum works like a monogastric stomach.
Q 03The smallest compartment of a cow's stomach is nicknamed the "honeycomb". Which one is it?
Reticulum
Its lining really does look like honeycomb, and it is where swallowed nails and wire tend to end up.

Aurochs
Mitochondrial DNA suggests the taurine line may trace back to as few as 80 wild animals tamed in upper Mesopotamia.
Q 05The wild ancestor of cattle survived in Europe until its last cow died in a Polish forest. In what year?
1627
The final herd in Jaktorów Forest had dwindled to just four animals by 1601, and the species was gone a generation later.
Q 06How long is a cow's pregnancy?
About nine months

Cows
At roughly 400 million tonnes they edge out krill (379 million) and humans (373 million).

330°
The trade-off is binocular vision of only 30° to 50°, compared with about 140° in humans.
Q 10Bulls cannot actually see red. So why is a matador's muleta that colour?
To hide bloodstains
Cattle are dichromatic, so it is the movement of the cloth that provokes the charge, not its colour.
Q 11About how many hours a day does a domestic cow spend asleep?
4
Cattle doze lightly on their feet but have to lie down for deep sleep, which is one reason cow tipping is a myth.
