Iodine barrier teat dip
First Claim
1. An aqueous protective antimicrobial film forming composition, formulated to reduce the incidence of both contagious mastitis and environmental mastitis in a dairy herd, said composition consisting essentially of, in an aqueous base:
- (a) an effective film forming amount of a polyvinyl alcohol composition having a degree of hydrolysis greater than 98.5%;
(b) an effective amount of a polymeric thickener composition; and
(c) an effective antimicrobial amount of an antimicrobial iodine-nonionic complex composition;
wherein a film formed from the protective composition can be substantially removed from the treated animal in less than 5 minutes.

Abstract
A protective aqueous antimicrobial film forming composition that can be applied to dairy animals to form a protective film. The film can be used to reduce the incidence of both contagious and environmental mastitis in dairy herds and can be formed from an aqueous composition that can contain a nonionic iodine complex, a polyvinyl alcohol composition, having a degree of hydrolysis greater than 92%, preferably greater than 98%, and a thickener. The aqueous mixture can be applied to udder and teats of dairy herds to form a protective coating that can prevent infection from staphlococcus, streptococcus, klebsiella and other pathogens. The film can be removed using water in a convenient short period of time permitting efficient milking operations. After milking, the composition can be reapplied to the herd and can protect the herd from mastitis until the herd is again milked. The material of the invention has the property that after application and drying both films and plugs of the protective coating is softened and removed even in cold water in a convenient time frame.

9. A method for reduction of contagious mastitis and environmental mastitis in a dairy herd, the method comprising:
-
(a) applying an aqueous protective antimicrobial film forming composition to an animal in a dairy herd comprising; (i) an effective film forming amount of a polyvinyl alcohol composition with a degree of hydrolysis greater than about 92 wt %; (ii) an antimicrobial amount of an iodine-nonionic complex composition; and (iii) a thickener;
to form a film on the teat and a plug on the teat end; and(b) when needed, removing said film and plug by contacting the teat with an aqueous wash, substantially removing the protective composition in less than 5 minutes, and wherein an effective amount of a colorant is optionally present in said composition. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
