The thurl is located approximately half-way between the hips (aka hooks, aka tuber coxae) and the pins (aka tuber ischii). The thurl is the external manifestation of the greater trochanter of the femur.
In much more layman's terms (if you didn't understand the thick scientific jargon in the first answer above), the thurl is the flat portion of the pelvis between the hooks or hip bone and pins (or pin bone) of the cow. It is one of the areas where you judge the body condition score or fatness level of a cow. The thurl on a dairy cow is the same thurl on a beef cow.
It is all part of the hip bone or pelvis of a cow, and is one of the anatomical structure of a cow that is used in judging body condition scores of a cow--be she beef or dairy.
Yes: to produce milk.
A cow. Or, if you want to go into specifics, a dairy cow.
Dairy cows are not built or made to be camouflaged. They are a product of intensive artificial selection for the purpose of being used by humans, not to survive in the wild.
It gives more milk than what it would normally produce for its calf. That's what constitutes a cow for being a dairy cow.
Dairy
The dairy cow.
That all depends on the breed. Are you asking about a dairy cow or a beef cow, and what breed of dairy or beef cow?
Dairy cattle like Holsteins, Brown Swiss and Jerseys.
A dairy cow would die a matter of a few weeks before she even gets to the point where she is deemed "feral." I would see a beef cow becoming feral, yes, but not a dairy cow.
There's not really an answer... You just call it a cow...
