Abstract

FIELD: veterinary science.

SUBSTANCE: invention relates to veterinary medicine and is intended for treatment of mastitis in cattle. Method involves intracisternal administration of administering medicinal agent. Medicinal agent used is a mixture of air saturated with phytoncides of garlic with addition of carbon dioxide in amount: carbon dioxide-10-20 vol%, air saturated with phytoncides of garlic - balance. Said mixture is administered by means of Bobrov apparatus once a day for 1-3 days in dosage of 0.5-1.0 l before noticeable inflation fraction of udder.

Description

The invention relates to veterinary medicine and can be used in the treatment of mastitis in cattle, mainly cows, including the most common serous mastitis, usually associated with improper milking, poor care of the udder, bruises of the udder, cracks in the nipples.

Very often the treatment of animals with this disease is based on the use of antibiotics, see, for example, RU 2491921 C1, publ. 09/10/2013. This method involves the introduction of a solution containing ampramycin in combination with a small amount of xanthan gum, which is a polysaccharide. The solution is administered intracisternally after the last evening milking in an amount of 10 ml once. The use of antibiotics has a number of negative consequences, in particular, it causes the appearance of microorganism strains resistant to them, which sharply reduces the effectiveness of treatment; many antibiotics are strong immunosuppressants, which worsens the course of the disease and lengthens the recovery period of the animal. Milk containing an increased residual amount of antibacterial agents is unsafe for human health. For these reasons, most countries regulate the permissible levels of potentially hazardous substances in raw milk (cream), and according to the Federal Law of the Russian Federation No. 88-FZ of June 12, 2008, the content of antibiotics and inhibitory substances in these products is generally unacceptable.

A known method of treating mastitis in cows, including the introduction of a biogenic stimulant made on the basis of the placenta with the addition of a liquid fraction of hazel obtained by dry sublimation, RU 2454971 C2, publ. 07/10/2012.

The solution is injected into the area of the external inguinal lymph nodes in a dose of 50-60 ml, depending on the live weight of the animal 3-4 times with an interval of 46-48 hours. This method is ineffective, since biogenic stimulants do not have a bactericidal (bacteriostatic) effect. As for the addition of a liquid fraction of hazel obtained by dry sublimation, its antimicrobial properties are very small and cannot significantly affect the effectiveness of the method.

There is a method of treating mastitis in cows by intracisternally administering a drug, which is a solution containing Vivaton veterinary - 10%, ACD-2 - 2-4%, Bursantal - 6%, 0.9% isotonic solution - up to 100%, RU 2522247 C1, publ. 07/10/2012.

This method is adopted as a prototype of the present invention.

The disadvantage of the prototype method, as well as other known methods of treating mastitis by intracisternal administration of liquid solutions containing drugs, is that the solutions of the injected drugs do not always reach the foci of inflammation, which leads to low treatment efficiency; it should be noted that the foci of inflammation during machine milking are, as a rule, in the part of the udder farthest from the nipple, which is caused by injury to the udder by the machine for milking. As a result, unhealed adhesive inflammation occurs.

The objective of the present invention is to increase the effectiveness of treatment.

According to the invention, in a method for treating mastitis in cattle, which includes the intradermal administration of a medicinal product, a mixture of air saturated with volatile garlic with the addition of carbon dioxide in the amount of:

carbon dioxide - 10-20 volume percent;

air saturated with volatile garlic - the rest,

while this mixture is administered using the Bobrov apparatus once a day for 1-3 days at a dose of 0.5-1.0 L before the sensible inflating of the udder lobe begins.

The applicant has not identified any technical solutions identical to the claimed one, which allows us to conclude that the invention meets the condition of patentability “Novelty”.

The implementation of the distinguishing features of the invention provides a technical result, consisting in the fact that the gas mixture introduced into the diseased quarter of the udder almost always reaches all, including remote, foci of inflammation, thereby preventing adhesive inflammation and preserving productivity, while garlic volatiles have pronounced bactericidal properties, and carbon dioxide provides effective removal of inflammatory products.

These circumstances allow us to conclude that the claimed technical solution meets the condition of patentability "Inventive step".

The claimed method is as follows.

In Bobrov's apparatus, crushed garlic is placed in an amount of 20-30 g and solid carbon dioxide (“dry ice”). The mass of solid carbon dioxide is calculated taking into account the provision in the gas mixture of 15-25 volume percent of CO ₂ . When the content of CO _{2 is} less than 15 volume percent, the removal efficiency of the products of inflammation is insufficient, and when the content of CO _{2 is} more than 25 volume percent, this efficiency remains practically unchanged. Prior to the procedure, cows with signs of mastitis are injected with 10 ml of a 0.5% solution of novocaine into the diseased quarter of the udder using a syringe or polyethylene catheter, which is connected to the Bobrov apparatus outlet rubber tube. Then, through a catheter inserted into the nipple canal, a mixture of air and carbon dioxide saturated with volatile garlic and carbon dioxide is pumped in an amount of 0.5-1.0 L before the inflating of the udder share once a day for 1-3 days.

Tests of the claimed method were carried out on the basis of ZAO Manino, Kalacheevsky district of the Voronezh region on a group of 12 cows with serous mastitis. The gas mixture was introduced once a day for two days. As a result, in 9 cows a full recovery occurred, in 2 cows the condition improved significantly, in 1 cow there was no improvement. The treatment of animals remaining sick was continued for another 2 days, after which another 2 cows recovered. One cow did not significantly improve over the entire treatment period.

In the near future, it is expected to use the claimed method in the farms of the Tosno district of the Leningrad region.
