As you probably already know, the milk let-down process is not as “instant” as turning lights on and off. And, nor does it just happen on its own. Cows need milkers to remain quiet and calm, help stimulate their udder, and allow them adequate time to lower their milk.
Sure, some cows walk into the parlor already dripping milk. And others seem to take forever regardless of how well you stimulate them. And although every dairy has cows at both extremes, the majority of cows need ninety seconds to two minutes to let their milk down.
So… why does it take approximately two minutes for most cows to give us their milk?
