A milk delivery system is disclosed comprising a reservoir, feeding units from which livestock can drink the liquid feed, supply and return lines connecting the reservoir and feeding units, liquid feed pressurizing means, and pressure regulation means on both the supply and return lines to control the liquid feed pressure within the system, such that the pressure differential between the first and last feeding units may be maintained substantially constant. Mixing means are preferably employed in the reservoir, controlled by a PLC processor for automatic intermittent mixing, and a feeding unit configuration is also disclosed employing a push-type omni-directional mushroom valve for animal-actuated operation with low pressure discharge.
