About 100-125 head cows and calves
Not necessarily. It means cattle in a collective term, not cows as in only cows with calves, or dry cows or pregnant cows or bulls or steers or heifers or whatever. When a cattleman says that he has 50 head of cattle, he means cows, bulls, steers, heifers and calves, not just the cows themselves.
A head of cow properly spoken is one cow. Head refers to a number, or rather a variable. to use the term head is just a matter of counting, usually critters, say like sheep , horses, goats even people. Asking for a head count is asking how many. "I saw a herd of Elk about 10 head. they were mixed in with a herd of holstein cows and 4 or 5 head of horses".
As of 2014, there are an estimated 2.945 million head of cows in inner Mongolia. The numbers rise each year.

An easy answer to this is, "depends" on the meaning of this question, referring to cost or, how many is a head of cattle. The word "cattle", is plural. I will assume the question is "how much was a cow" in the 1860's As a "head" refers to a number. A head, would be just one, 100 cows would be "100 head". It is improper to call steers, heifers, and bulls cows. each has a different use and you would not want to buy 5 cows to replace the old ones you have you would want heifers, nor would you want to buy steers when you need bulls and there, is the need for distinction. therefore, to count your herd of 40 cows 10 bulls 25 steers and 25 heifers is 100 head. now that that is straightened out, the cost of one head in 1860's was about $3.00.
