Heifer. Heifer is the female cow who has passed the calf stage but has not reached the cow stage. Usually, the calf stage ends when the age reaches 10 months from birth. A female will be called a cow when she becomes a mother after reaching the reproductive viability. The heifer is the middle stage of the calf and cow.
Ox vs Cow. A cow and an ox are members of the Bovinae subfamily. In terms of physiology, cows and oxen do not have significant differences. But humans differentiate cows and oxen according to their specific use in the farm. So here are some unique differences between a cow and an ox. A cow is a female. To be called as such, it should be approximately 4 years old and has given birth to at least one calf. Its male counterpart is called a bull. An ox, on the other hand, is a castrated mature bull. So gender can be said as the primary difference between an ox and a cow. A cow is raised as a livestock for its meat. It is also a dairy animal which is a source of milk and other dairy products like butter and cheese. Meanwhile, the ox is a draft animal.
