So what?
You and @Freda can eat mung beans and drink coconut milk if you wish but to attest that a cow is mentally traumatised every year to whatever extent is cookie bear land.
How do you explain that the most fertile time for a mare or a cow is immediately after giving birth?
If you don't like it don't drink milk, eat yoghurt, icecream or cheese!
I suppose you both find it OK to "break-in" young horses and take them away from the herd? Of course you'd be happy if those young fillies were left in the herd to get in foal at two or those young colts to be banished from the herd.
@the galah and @Freda why both having any interest in horse racing at all?
Oh and back to cows have you seem what the mother does to the calf when she decides to ween it so she can focus on feeding the next one inside her?
