Why ">" and not "="? Is this true for other animals too or are cows special?
Well... the example ran away like this: "If there was a fire and I was given the option of saving just the cow or just the person, I would save the cow". Presumably it would be the same with a pig or a dog.
This is a trasposed version of the trolley situation: 'I would not actively kill any human, but given the choice, I consider a cow to be more valuable'.
The motivating reason was something on the line of "humans are inherently evil, while animals are incapable of evil".
I'm currently unconvinced either way on this matter. However, enough arguments have been raised that I think this is worth the time of every reader to think a good deal about.
