Ontario has been promoting this strategy and publishing this chart for decades illustrating the effects of choosing to shoot a bull vs a cow,at least since the early 90s anyhow when I lived there.
They also consider calves expendable,reasoning that calves are the most vulnerable part of the population and most susceptible to wolf predation and winter kill,and when a cow loses a calf to hunting she will breed again sooner,therefore they allow everybody to buy a calf tag.
ie;they have group applications or “party hunting” as they call it for the moose draw and allow up to 8 hunters per party.
Everybody buys a tag valid for calf at the time of application,then the party of 8 might for example get drawn for let’s say 1 or 2 or more adult tags,anybody in the hunting party can fill the adult tags until they are all filled,and everybody is licensed to take a calf.
