Most often, catarral mastitis in cows with characteristic clinical signs is expressed after calving. The owner learns about the presence of the disease only when the acute form occurs. At this point, some flakes float in the milk, and the cow “burns” from the temperature, and it has no appetite at all. About what happens in the inflamed udder of the cow during this period, and how this pathology outwardly manifests itself, we will describe in this article.
"Dirty work" infection
Most often, the catarrhal form of mastitis affects one or two parts of the udder of a cow. The first characteristic symptom is a change in the consistency of milk. It becomes watery. With the development of the disease it becomes less, there are clots of casein, which do not always go out, clogging ducts. Then the knots can be felt with your fingers. Their size increases to the size of small nuts.
The main cause of the disease is considered to be unsanitary conditions in the room where the cow is kept. Through possible scratches and cracks, the infection gets into the nipple and begins its “dirty work”. As pathology develops, the udder becomes hot, gradually increasing in temperature to the whole body of the cow. Her appetite is gone, and the mammary gland swells and becomes inflamed.
Depends on the place of infection
In case of inflammation of the mammary gland in a cow due to the occurrence of catarrhal mastitis, the glandular epithelium of the udder is rejected, that is, those secretory cells in which milk is formed.
Two catarrhal forms of mastitis in cows should be distinguished. Their symptoms vary depending on the site of infection. The first type is when the process starts in the nipple canal and goes into the cistern. Second, inflammation affects the alveoli of the udder.
Regardless of the form of catarrhal inflammation, its causes may be the same. In any case, pathogenic organisms get into the mammary gland through some kind of damage, so the owner of the cow must be very attentive to such an important organ as the udder. Do not graze the cow in places where too tall grasses grow, especially with prickly and cutting leaves (sow thistle, burdock).
Symptoms of inflammation in the tank
If the inflammation started due to the fact that microbes got into the tank through the nipple canals, then the characteristic features of this form appear as follows:
- At the beginning of the milking, the milk has a liquid consistency with falling casein flakes (these are dead tissues);
- in the process of further milking, the product externally becomes normal;
- it is possible to feel the inflamed consolidations in an udder only in several days;
- after 3-4 days the nipple becomes hard;
- with the development of the disease, the nipple becomes clogged with clots;
- after 5-6 days, nodules appeared in the udder by the size of a small nut;
- the resulting milk clots hardly pass through the nipple canal;
- milk yield almost always stays the same or slightly decreases.
One of the causes of catarrhal mastitis in the milk tank is called the milking method with tweaks. These actions often lead to damage to the mucosa in the nipple.
Inflammatory process in the alveoli
The disease develops in a different way if the infection has penetrated into the alveoli, the tissues that produce milk. They have a porous structure. Microbes that multiply rapidly during inflammation damage this secretory tissue, making it stiff. Outwardly, this is manifested in swelling and udder swelling.
The microbes enter the alveoli with blood, which, in a healthy state, supplies the secretory tissues with all the necessary nutrients for milk production. But if there is an infection in the body, it is also a supplier of a huge number of leukocytes that cause inflammation.
The increased reproduction of harmful microorganisms causes the milk ducts to expand. They accumulate catarrhal secret. The affected proportion of the udder increases, and its size does not decrease even with full milk delivery. The product itself becomes liquid and remains so throughout the milking. After settling in it is shown curdiness, yellowish flakes, and even a purulent sediment falls out.
Do not start the disease
During the illness of catarrhal mastitis in the body, pathogenic pathogens struggle with the cow's immunity. The outcome of the battle decides on time medical assistance.
The essence of the treatment is to remove the udder swelling, which occurs as a result of blocking the milk ducts formed clots. It is the impossibility of the release of fluid causes such a condition in a cow. Therefore, regardless of the form of catarrhal mastitis, it is necessary to milk as often as possible from the patient's udder.
Treatment of a cow usually takes 7 to 10 days. If it is started on time, the deficiencies in the care and maintenance of the animal are corrected, then you can count on a full recovery. If the process is started, then complications with the transition to a more serious stage (fibrinous mastitis) with subsequent uterine atrophy are not excluded.
Bad milk must be destroyed.
During the treatment of catarrhal mastitis, the following complex measures are proposed:
- the cow is not driven out to pasture;
- give it a clean, dry and warm stall;
- provide a soft fresh straw bedding;
- exclude from the diet juicy food and concentrates;
- the amount of drinking water is limited;
- more hay is introduced into the diet;
- manual milking is carried out every 4-5 hours;
- apply compresses and ointments on the udder, broad-spectrum antibiotics and physiotherapy.
When milking a sick cow, you need to use special dishes to collect milk. Despite the fact that it is unsuitable for consumption, in no case should you drain the liquid on the ground. The pathogens contained there will spread around the perimeter, fall on the litter or inventory. As a result, an insidious infection spreads everywhere and can affect all livestock.
Only correctly and strictly in moderation
The use of compresses is also associated with the implementation of certain rules. On the first day of the illness, a cooling lotion is made, since the udder has a high temperature, and the cold will ease the condition of the cow. To do this, dilute the clay in cold water, add a couple of tablespoons of vinegar and spread the pulp on the udder. You need to change the coating every hour, as it quickly heats up and ceases to have any effect. But you should not get carried away, having made such 3-4 coatings, you will have to stop so as not to chill the animal.
An integral part of the treatment of a cow is an udder massage using ointments, for example, Ichthyol. Here it is necessary to take into account an important point: the direction of stroking movements of the hands should be directed strictly from the top down. Thus, it is possible to push the formed clots to exit through the nipple.
Warming compresses, as well as massage with warming ointments, can be started only for 3-4 days, when the healing process is underway. Heat helps the resorption of nodes. For this purpose, camphor alcohol is used. As a supplement, you can use a laser device "Paw" for one or two minutes.
Separately about injections and antibiotics
Injections, which are used in the treatment of catarrhal mastitis in a cow, are of several types. These can be hormones, for example, oxytocin, which accelerates secretion. Therefore, they prick for 10-15 minutes before serving the milk. Dosage - 50 units. every 12 hours. The injection is done intramuscularly or subcutaneously.
We recommend using trimecain (0.25% or 0.5%) for anesthesia, which lasts longer than traditional novocaine. For blockade in the area of the udder enough 50 or 100 ml of the drug.
And finally, antibiotics, which are used to deliver the main blow to the disease and get the best effect. It can be long-known penicillin, bitsillin-3 or bitsillin-5. They are injected intramuscularly, counting the dose by the weight of the cow. 1 kg - from 3 to 5 thousand units. medication. Duration no more than 4 days.
Among the modern means we note cefuroxime. One form of release is powder, which is dissolved in water for injection. (750 mg per 3 ml of water). The average daily dose is 10-12 g.
It should be remembered that antibiotics along with the benefit and harm. Therefore, to restore the destroyed membranes of the udder, it is useful to puncture trivitamin or tetravit.
Care should be taken to treat catarrhal mastitis with antibiotics. It is advisable to know if the cow is allergic to any component.
The introduction of drugs through the nipple
Now we will tell you in detail about the process of administering drugs directly into the cow's udder through the nipple.
First of all, you need to thoroughly wash your hands. Then sanitize the nipple itself. To do this, it will be enough to wipe it with medical alcohol. The catheter used for insertion must also be sterile. They are made of metal or plastic.
First, the udder is completely free from the milk available there. If clots and mucus form interfere with this, then a solution of salt (1 g), soda (2 g) and boiled water (100 ml) is poured into it. After 20 minutes, after a light massage, the process will go easier, and the udder will be able to release completely.
Now a local antibiotic can be administered through the udder nipple, for example, masticide. Before use, it should be heated to 25-26 degrees. There is enough 10 ml of a preparation for one procedure which repeat every 12 hours within three days.
Having pumped the medicine inward, it is useful to massage the udder, but now from the bottom up, helping the spread of the drug.
Milk from a cow that has had catarrhal mastitis can be eaten only 5 days after the last injection of the drug into the body.
