The sacrament of giving blood is a big sacrifice for the alpha - who probably needs to feed again immediately afterwards to regain vitality - and is not to be taken lightly or given to undeserving creatures. An alpha vampire would be feeding all the time, being fully free-willed, and would have the highest reserve of blood within its body. When they feed on living blood, they become briefly 'revivified', enough to regain some semblance of a living body, which fades if they do not continue feeding.

I assume that vampires perhaps cannot make blood like a living body can, and this is why they need to feed. In 5e DnD, if a victim isn't allowed to drink the blood of its master, it becomes a spawn completely under the master's control. I believe the vampires in Anne Rice's books, like 'Interview with a Vampire', undergo a similar ritual to create other vampires, where a victim must drink blood from the vampire to become one themselves, otherwise they simply die.
