A milking claw for a dairy animal has a bottom having an outlet tubular member
having a flow passage of a first vertical height, and a nozzle having an opening
passing milk therethrough from the claw bottom to the flow passage. The nozzle
opening has a second vertical height less than the first vertical height, such
that milk level in the claw bottom need only rise to the level of the second lower
vertical height of the nozzle opening rather than to the level of the first higher
vertical height of the flow passage of the outlet tubular member, to provide a
pressure differential between the vacuum in the outlet and the vacuum in the claw,
whereby to draw milk from the claw in smaller more frequent slugs as compared to
higher volume less frequent slugs while otherwise waiting for milk level in the
claw bottom to rise to the level of the first vertical height.
