Abstract:
A combined foam bovine teat and udder dip, and after milking post teat dip and udder wash formed by admixing a surfactant, water and a bacteria control agent with pressurized air in a flow and line mixer and subsequently depressurizing the admixture from an initial pressurized value in the flow and line mixer down to atmospheric pressure and into an open orifice in a connected teat cup surrounding the teat and adjacent udder area, the consistency of the foam being sufficient to apply penetrating and adherent foam to the teat and adjacent udder area for an effective contact time prior to milking, and without significant run-off, thereby enabling ready removal of deleterious material therefrom; and if desired, following cessation of milking the post teat dip and after milking and udder wash which is not wiped off enables the teat including the teat end, for a sufficient length of contact time, thereby causing fresh available liquid and foam to cover the teat end, and hence the teat canal opening with foam when the teat sphincter muscle is both open and closed, and thereby reduce the possibility of infection through the teat canal.
