Abstract
Abstract Iodophorous udder disinfecting preparation comprising a iodophor in the form of an alkylphenoxypoly(ethyleneoxy)-ethanol-idodine complex or a polyvinylpyrrolidone-iodine complex, whereby the complex is present in an amount corresponding to 0.01, preferably 0.1 to 0.4%, by weight of free iodine, and 5 to 10% by weight of urea, an organic and/or inorganic acid to pH 1 to 5, and water and/or other solvent to 100% by weight, and whereby the udder disinfecting preparation according to a preferred embodiment further contains an alkoxylated glucose derivative in an amount of up to 4% by weight. By means of the udder disinfecting preparation a good bactericidal effect is obtained with a low iodine concentration, as well as a good skin emollient effect. The invention further relates to a method of increasing milk production by treating the teats with such an udder disinfectant.
