Description

The invention relates to livestock, in particular to veterinary medicine, and can be used for post-treatment of the nipples of the udder of cows.

Within 30-40 minutes after milking, the sphincter of the cow's nipple is still open, which can serve as an infection gate for the penetration of mastitis pathogens. Thus, an inflammatory process can develop in the udder. Sequential treatment provides the formation of a protective film on the nipples until the sphincter closes and in the intervals between milking, which makes it possible to protect the udder of cows from the penetration of pathogenic microorganisms.

A known method of treating the udder of cows with a 1% solution of asepur (Cherepakhina L.A. Mastitis of cows of coccal etiology as a factor infection and rational methods of its therapy. Monograph / L.A. Cherepakhina - Orel, Orel Publishing House GAU, 2007. - 156 p. ) [one]. This method does not allow for efficient post-treatment of the udder, because in this case, partial penetration of pathogenic microflora through the nipple canal occurs.

The disadvantage of this method of processing the udder is that the solution does not allow for a sufficiently long action of protecting the udder from the penetration of microorganisms.

The objective of the invention is to provide a longer hygienic protection of the nipples of the udder of cows, as well as the softening and moisturizing effect on the skin of the nipples.

The problem is achieved due to the fact that the means for post-treatment of the nipples of the udder of the cows contains an aqueous solution of chlorine dioxide, glycerin and xanthan gum in the following ratio of components, mass. %: aqueous solution of chlorine dioxide (90 mg / l) - 93.8-93.2; glycerin - 6.0-6.5; xanthan gum - 0.2-0.3.

Chlorine dioxide is a powerful antimicrobial drug, which, according to the degree of exposure to the body according to GOST 12.1.007-76, when applied to the skin, belongs to the 4th class of low-hazard substances. This oxygen-containing agent that acts on microorganisms and their spores as a powerful oxidizing agent does not form chloramines during and after disinfection. Compared with other disinfectants, chlorine dioxide does not interact with biological material with the formation of harmful substances, it has a universal biocidal effect on all types of microorganisms, including viruses, spore-forming bacteria, and fungi.

Xanthan gum is a biopolymer capable of stabilizing solutions. It has good emulsifying properties, forms a protective film on the surface, moisturizes the skin and does not have a harmful effect on the body.

Glycerin is an organic compound, a representative of saturated trihydric alcohols and is a colorless viscous liquid. Used to dissolve drugs, increase the viscosity of liquid preparations and protect against changes during fermentation of liquids. In a small percentage it has a moisturizing and softening effect. It has antiseptic and preservative properties that are associated with hygroscopicity, due to which dehydration and the death of pathogenic bacteria occur.

The product helps protect the skin of the nipples of the udder between milking, prevents the penetration of bacteria into the nipple canal before the sphincter closes and provides a healing effect on the skin. Using pure chlorine dioxide may cause skin irritation. The addition of components such as glycerin and xanthan gum creates a viscous consistency in the solution, gives stability to the final compound of the product, forms a protective film on the surface, has a moisturizing and softening effect on the skin of the nipple, which provides longer-lasting hygienic protection of the nipples of the cow's udder.

To prepare 100.0 of the proposed funds, 93.8-93.2 aqueous solution of chlorine dioxide (90 mg / l), 6.0-6.5 glycerol, 0.2-0.3 xanthan gum are taken and mixed thoroughly. In order for the cow to feel comfortable and calm during the post-treatment period of the nipple, the temperature of the product should be between 40-45 ° C. After milking, the udder nipples are treated as follows: each nipple is immersed in a special cup for 2-3 seconds. The product remains on the nipples of the udder of the cow until the next milking. Compared with a 1% solution of asepur, the proposed product is longer on the skin and therefore provides longer hygienic protection of the nipples of the udder of cows due to the fact that it contains additionally viscous glycerin and xanthan gum.

Within a month, a test of the proposed agent for post-treatment of the teats of the udder on 25 lactating cows was carried out (1 experimental group). In the second experimental group, consisting of 25 cows, 1% asepur solution was used to treat the udder. There were also 25 cows in the control group, in which treatment of the udder was not carried out with the preparations, but the udder was washed with plain tap water. Before the experiment, all cows were examined for mastitis visually and with the help of a diagnosticum - kenotest. All experimental animals were clinically healthy.

Evaluation of the effectiveness of the means for processing nipples of the udder of cows was carried out by the number of cows with mastitis and skin irritation of the nipples of the udder of animals during the experiment.

According to the results of studies of the post-milking treatment of the nipples of the udder of cows with the proposed means, high prophylactic effectiveness was established. After the experiment, all cows were examined for mastitis. In the first experimental group, 1 cow (4%) was revealed with mastitis for a month, 2 heads (8%) were revealed with slight cracking of the skin of the nipples of the udder. In the second group, 4 cows (16%) were identified with mastitis, 5 goals (20%) with skin irritation. In the control group with mastitis, 7 animals were detected (28%), with damage to the skin of the nipples - 6 animals (24%). The results of the studies are shown in table 1.

To study the effectiveness of the post-milking treatment of the nipples of the udder, swabs were taken from the nipples after milking and after the post-milking treatment in the following periods: 1 - immediately after completion of the milking process and removing the teat cups; 2 - after 30-40 seconds after post-treatment; 3 - 5-7 minutes after post-treatment. Washings were added to test tubes with 10 ml of physiological saline. Then, 0.1 ml was taken from each tube and introduced into sterile Petri dishes with 25 ml MPA cooled to 45 ° C. After the Petri dish, they were placed in a thermostat at a temperature of 37 ° C for 48 hours, then visually counted the formed colonies of microorganisms. The results of counting colonies of microorganisms are shown in table 2.

Thus, the testing of a new tool for post-treatment of the nipples of the udder of the cows showed high prophylactic efficiency and provided longer hygienic protection of the nipples of the udder of the cows.
