Excellent as a farming mount. A lot of thatch for compost, gets a lot of seeds. Decent speed and weight, also as their pregnancy is faster than most of mammals and excellent meat source. Easily outruns most predators. I have a deer ranch constantly breeding, babies give a lot of prime meat.
They are very good combat and transport mounts. The males can attack, which allows them to gather thatch very efficiently. The females have no attack, but are a little faster, as there are no horns to weigh them down. There's also something satisfying about riding a moose. WHEEEEEEEEEE
