In New Zealand, there are cows all the place even in the suburbans.
In parks where there are tourists, the local authorities rent out public parks to farmers. The cows eat the grass, the council doesn't have to mow the paddocks. It is a win-win situation.
"Pleack!" lands the cow pat. And if you don't watch your steps, "Yukk!" you step on a warm squishly cow pat.
My friend was a gentleman farmer, his cows were indeed fertilised " by a farmer with a long-sleeved rubber glove" using a frozen straw. His poor calves are separated from their mums and auctioned off. They become choice veal in some high class restaurant. I am not sure if Gordan Ramsay or Jamie Oliver would use them.
