The youngest calf loves to brush up against me when I'm around, even nose-kisses every day. I get cow licks when I'm feeding them.
My most ferocious cat comes to me when he's injured after getting bitten by his brother (who just wants to be) - I was worried about his swollen face, but vet wasn't available - opened a wound next to his eye that had festered and squeezed out disgusting amount of pus, while this boy sat there, wincing in pain, but knew I was helping. (He's recovered now)
