Description

 The invention relates to agriculture, in particular to methods for maintaining the udder of cows after starting in a healthy state.

 A known method of launching cows, which consists in the fact that cows for 2.5 months. before the expected calving are formed into a group. During the launch period, which lasts two weeks, milk samples are taken every 4-5 days to determine the type of microorganism. During the last milking, the secretion of the udder for the presence or absence of flakes is examined. For the start-up period, concentrates are eliminated and juicy feed is reduced. In the dry compartment in cows, the secretion of the udder is examined once a decade.

 Among the disadvantages of this method is the complexity of operations, which nevertheless do not keep the udder of dry cows in a healthy condition. In addition, 2.5 months before the expected date there is no need to form a group. Run the cow for 2 weeks and during this time take milk samples 4-5 times and sow the same number of times and determine the type of microflora that will not change in 2-3 days. Performing the recommended techniques is laborious and takes more than one week.

 There is a method aimed at maintaining the udder in a healthy state, in which endotoxin or colchicine was administered in a quarter of the udder.

 The disadvantage of this method is that the injected drugs do not act on the entire microflora of the udder, but selectively, at the beginning of the dry period, on streptococci, and in the end, more on coliform bacteria. In addition, the penetration of infection through the nipples of the udder is not excluded and this leads to re-infection. 75% of herds of animals (cows) do not have udder diseases, they do not need to be treated, and it is impossible to prevent the disease in this way.

 The aim of the invention is to reduce the disease of the udder of cows with mastitis by eliminating the penetration of infection through the nipples into the udder. This is achieved by the fact that in the known method for the prevention of mastitis, which consists in launching cows, controlling the udder, preventing udder disease, by administering the preparation according to the invention to the cows in the dry period 11-12 days after the launch, molten paraffin is introduced into each healthy udder nipple as 2 -2.5 ml.

The method is carried out as follows. In dry period cows on day 11-12 after launch, pour the udder and teats with warm water t = 40-45 ^{° C,} wiped dry, determine the presence or absence of mastitis udder quarters, in the absence of disinfecting teats 0.1% solution monochloride iodine. Then, in each healthy quarter, using a syringe (without a needle) with a capacity of 10 ml, molten paraffin in an amount of 2-2.5 ml is injected.

 To determine the optimal dose for paraffin administration, 60 animals were taken that did not have mastitis before starting, and formed 5 groups of 12 animals each.

 On the 12th day after the launch, the udder was monitored and molten paraffin was introduced into each healthy udder nipple, a certain dose in each group.

 The data on the effect of the amount of the administered drug in the udder nipples on the state of the udder are summarized in Table 1.

 For comparison, a group of cows was taken from 11 animals that were injected with colchicine. The disadvantage of this method is that it does not exclude the penetration of infection through the nipples of the udder and this leads to reinfection. When using colchicine, infection is reduced by only 50%.

 Studies have shown that the introduction of a dose of paraffin 1, 3, 4 ml worse preserves the udder of cows from infection, while there were more cases of udder disease than when 2 or 2.5 ml was injected.

 To determine the optimal timing of administration, 5 groups of healthy animals of 20 animals each were taken and the effect of the introduction of paraffin into the nipples of the udder on different days after lactation on the state of the udder was tested. The research data are given in table. 2.

 Table analysis 2 showed that the introduction of paraffin on day 11-12 after starting is more effective.

 Paraffin has an analgesic and antispastic effect, accelerates the resorption of hematomas. Under its influence, blood and lymph circulation increases, the processes of regeneration and tissue metabolism are accelerated. It has low heat conductivity and high heat-holding ability, is anhydrous, capable of generating heat for quite a long time, has almost no conventional properties.

 Using the proposed method provides a reduction in the duration of the launch period by 5-6 times; a decrease in the disease of the udder of cows mastitis through the nipple canal in the post-hotel period; reducing the cost of acquiring a drug that helps prevent mastitis.
