Bovine teat washing and lactation stimulation device

A method of treating teats protruding from a mammalian udder, the method comprising:

• a) contacting a teat treatment device with a portion of the udder surrounding a teat so as to enclose the teat within a treatment cavity of the treatment device, the treatment cavity having an open top and terminating at an open bottom and absent of any fluid transporting structure beneath the open bottom;
• b) delivering a liquid into the treatment cavity of the treatment device through a plurality of orifices in a side wall surrounding the treatment cavity and onto the teat;
• and
• c) discharging the liquid from the open bottom of the treatment cavity by gravity-driven flow into free space beneath the open bottom.

A teat treatment apparatus comprising:

• a) a tubular outer housing comprising a side wall bounded by top and bottom edges, an outer side surface, and an opposed inner side surface;
• b) a tubular inner shell comprising a side wall defining a treatment cavity having an open top for receiving a teat of an udder and terminating at an open bottom permitting gravity-driven liquid drainage out of the cavity, the tubular inner shell being absent of any fluid transporting structure beneath the open bottom;
• the side wall of the tubular inner shell bounded by an upper edge defining the open top, a lower edge defining the open bottom, an inner side surface, and an opposed outer side surface;
• and
• c) an inlet port extending through the side wall of the tubular outer housing and in fluid communication with an annular cavity formed between the outer side surface of the side wall of the tubular inner shell and the inner side surface of the side wall of the tubular outer shell.
