Cow competition?

My Sim submitted her very happy cow with enriched milk to the competition. There was also another cow in the competition, happy and with normal milk. And my cow won third place. How could that even be possible, in which universe?

How everything in this game is just RANDOM.

I also submitted excellent milk worth of 30, there were two other competitors with normal milk worth of 20, but milk was not even taken into consideration for the prize.
