Can someone who actually has been involved with raising livestock answer this:
Is it necessary for a dairy cow to have given birth recently (and then have the calf taken away) in order for her to produce milk? Or will she produce milk no matter what (or is there a third option of which I am unaware)?
Related to this, must a chicken breed with a rooster to produce eggs, or will she produce and lay unfertilized eggs?
To lay my cards on the table, I’m wondering what sort of manipulation (if any) of the normal order of reproduction for these animals is necessary for us to enjoy the culinary benefits. (Just information, please: No angry diatribes. I just saw Rage Against the Machine in concert recently and I’m all full up with vague, unfocused self-righteousness at the moment).
