Um … the female equivalent of a vasectomy is a tubal ligation, not a hysterectomy. And tubal ligations can be done on an outpatient basis, too (and are somewhat easier to reverse than vasectomies are).
A common usage specifically for cattle in the singular is “Cattle Beast” You can google for this usage using http://www.google.com.au/search?q=“cattle+beast”
I guess “Cattle Beasts” is the plural equivalent
“Cattle beast”. I like that.

Hm, is that so? Women in my family generally go one of two ways.
- Medically forced to go all the way(the surgery, not The Act), or
- Use pills and other non-surgical tricks.

You don’t really need a singular from for “cattle” as by the time you are talking about such an animal in the singular, you know it’s sex (& species… and perhaps even name). The whole purpose behind the word “cattle” is to lump all soon-to-be-hamburger critters into one general sexless noun.
As someone said above, if you’re in the business of keeping and raising beefcritters, their gender is Real Important, so the separate names for different sexes and numbers have persisted.
But increasingly I notice that if you’re not in the business of keeping them, i.e., like most of us urban folk, the word “cow” is being used to designate any domestic ox regardless of gender. Professional and other careful writers still seem to recognize the gender implications of the various terms. But in casual conversation I often hear reference to “male cows”, or “this cow, he did such and such”…
In my part of the English Midlands, cattle of either gender are referred to as ‘beast’, which can also be a plural.
Geese is also properly just the female plural of that particular species. A male is a gander.
