Abstract

Abstract A method of preparing, treating and then milking cows includes the use of a flexible wipe (A) constructed of hydrophilic material containing a moisture-activated antimicrobial composition. The process includes washing teats and udder of a milk-bearing cow with water or an aqueous soap solution; simultaneously drying, sanitizing and conditioning the thus-washed teats and udder with the moisture-activated antimicrobial wipe comprising a hydrophilic substrate impregnated with an antimicrobial agent, effective to sanitize the teats and udder; and then milking the thus-prepared cow.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 197 words
The method of preparing cows for milking while treating the teats to reduce contamination by reducing the concentration of bacteria of the milk collected consisting of the following steps performed sequentially: A. washing the teats of a milk bearing cow by applying water or an aqueous soap solution thereto so as to leave the teats wet therewith; B. manually massaging the tests while still wet with a flexible wipe constructed of a hydrophilic material selected from the group consisting of wool, silk, jute, hemp, cotton, linen, sisal, ramie, rayon, cellulose esters, polyvinyl materials, polyolefins, polyamides, polyesters, paper or a combination thereof including about 0.5-5% by weight of a moisture-activated antimicrobial composition selected from the group consisting of biguanides, quaternary ammonium compounds and carbanilides releasable from the wipe by uptake of water; C. continuing to manually massage the teats with said wipe after moistening thereof so as to apply said moisture-activated antimicrobial composition released from the wipe to the teats to dry and to sanitize the teats; D. discarding said flexible wipe prior to preparing and treating another cow; and E. thereupon milking the thus-prepared cow; whereby washing and drying of the teats of a cow are accomplished.
Claim 2
Independent Claim 197 words
The method of preparing cows for milking while treating the teats to reduce contamination by reducing the concentration of bacteria of the milk collected consisting of the following steps performed sequentially: A. washing the teats of a milk bearing cow by applying water or an aqueous soap solution thereto so as to leave the teats wet therewith; B. manually massaging the tests while still wet with a flexible wipe constructed of a hydrophilic material selected from the group consisting of wool, silk, jute, hemp, cotton, linen, sisal, ramie, rayon, cellulose esters, polyvinyl materials, polyolefins, polyamides, polyesters, paper or a combination thereof including about 0.5-5% by weight of a moisture-activated antimicrobial composition selected from the group consisting of biguanides, quaternary ammonium compounds and carbanilides releasable from the wipe by uptake of water; C. continuing to manually massage the teats with said wipe after moistening thereof so as to apply said moisture-activated antimicrobial composition released from the wipe to the teats to dry and to sanitize the teats; D. discarding said flexible wipe prior to preparing and treating another cow; and E. thereupon milking the thus-prepared cow; whereby washing and drying of the teats of a cow are accomplished.
Claim 3
Dependent Claim 26 words
The method set forth in claim 1, wherein the flexible wipe includes a substrate having an absorption capacity of about 5-12 times its weight of water.
Claim 4
Dependent Claim 18 words
The method set forth in claim 1, wherein the flexible wipe includes a substrate comprising a non-woven fabric.
Claim 5
Dependent Claim 31 words
The method set forth in claim 1, wherein the flexible wipe includes a substrate comprising a non-woven fabric bonded by a copolymer of vinyl acetate with an acrylic ester or ethylene.
Claim 6
Dependent Claim 19 words
The method set forth in claim 1, wherein the flexible wipe contains 1.00%-2% by weight of said antimicrobial composition.
Claim 7
Dependent Claim 13 words
The method set forth in claim 1, wherein the antimicrobial composition is chlorhexidine.
Claim 8
Dependent Claim 14 words
The method set forth in claim 1, wherein the antimicrobial composition is benzalkonium chloride.
