I don't know about collecting the urine of a doe but, I know about removing the scent glands that doe rub togeather while they urinate to wash the scent onto the ground. Placed into zip lock bags the scent released can be regulated into the air. Place one in the freezer while using one, which will last several days or, just freeze for next year.
The darker the glands, the better but, the doe need not be in estrous as the scent of musk is still strong enough to catch the attention of the boys.
Just something I learned back in the day.
Word of caution; do not hang the gland from a 'ladder stand' unless you'r looking to test your safety harness. Just sayin'....
