The inflammatory process in the corolla and adjacent skin, accompanied by the formation of pus, is called phlegmon. The disease often occurs in cattle, so it is important to take care of prevention, regularly examine the hooves, and check their integrity. With timely medical measures, the cow quickly recovers, with a running corolla phlegmon, necrotic processes occur in the tissues, and the risk of blood poisoning increases.
Causes of the disease
The corolla - the area above the upper edge of the horny part of the hoof - becomes inflamed when an infection enters. Infection occurs with scratches (even small ones), fractures, uncomfortable position of the hoof, accompanied by compression of nerve fibers. The cow walks through the mud in the pasture, is in an uncleaned stall, as a result begins to limp.
Corolla phlegmon occurs when a cow has a weakened immune system, the body cannot normally fight an infection that has penetrated inside. Animals often scratch the skin above the hooves, but as long as the immune system is strong, staphylococci and streptococci - the main causative agents of inflammation - are not dangerous. When the cow is weak, does not eat well, the inflammatory process can even begin due to a micro-scratch.
More dangerous infections can be the causative agent of cellulitis. For example, foot and mouth disease.
Symptoms and Signs
The flow of corolla phlegmon is not the same, depending on the physical condition of the animal and the degree of spread of the infection. The formation of phlegm does not depend on the breed of cows, the size and thickness of the hooves. In many cases, the formation on the corolla of the hoof is an abscess. It is enough to open it, then apply drug therapy for the cow to recover quickly. With deep penetration of the infection, the inflammation captures the fatty tissue, the skin, the edge of the hoof, spreads to the part of the limb above the corolla and to the gap between the toes. In this case, the phlegmon is difficult.
The development of corolla phlegmon is rapid. Initially, the cow is limping because there is pain in the affected area when walking. If you touch the diseased area, the animal will shudder, moan. Further, the following symptoms of phlegmon appear:
- swelling of the affected area, accumulation of fluid, and then purulent exudate;
- increased body temperature;
- increased breathing;
- limb skin hot to the touch;
- detachment of the hoof horny plates;
- reduction of the gap between the fingers due to swelling and tissue pouring;
- hardening of tissues at the site of inflammation (when treatment is started, softening will begin after a few days);
- the formation of purulent ulcers (many burst, ripening in a few days);
- the release of blood-purulent exudate, spreading the infection to the surrounding tissues;
- staggering when walking, weak support on the inflamed limb;
- lack of appetite;
- predominant lying in the supine position;
- lethargy, depression, decreased milk yield.
Diagnosis of the disease
The examination is carried out by a veterinarian. Examines the cow's hooves, assesses the degree of swelling, reveals wounds and scratches that led to inflammation of the corolla. Checks how flexible the joints are. It measures the overall body temperature of the animal and also by touching how hot the skin of the lower limb is.
If the examination raises doubts about the diagnosis, then the veterinarian takes blood from the cow for analysis. An increased level of leukocytes in the blood indicates phlegmon. We are talking about neutrophilia, which confirms the presence of extensive purulent inflammation.

In addition to a blood test, arthropuncture can be performed - to pierce the joint capsule with a needle to take exudate for laboratory analysis.
Once the diagnosis is made, the veterinarian will prescribe treatment. If the corolla phlegmon is provoked by another infectious disease, then the treatment will consist of two stages. First you have to cure the underlying disease.
Methods for the treatment of corolla phlegmon in cattle
How to treat corolla phlegmon, the veterinarian determines, taking into account the depth of the spread of the infection and the neglect of the inflammation. If the infection is localized in the corolla, has not spread to neighboring tissues, then the treatment should consist in extinguishing the inflammatory reaction. For this:
- ichthyol ointment is applied to the affected area;
- put intravenous injections of novocaine and antibiotic;
- the inflamed area is treated with a solution of the drug "Furacilin".
In an advanced case, it is necessary to carry out a surgical operation - to open the swollen area above the purulent bladder, to remove the tissues that have undergone necrosis.
Next, you need to disinfect the wound: thoroughly treat it with hydrogen peroxide, after drying, apply the powder "Oxytetracycline" and "Sulfadimezin". Streptocid is also suitable for treating wounds. Bandage the wound, keep the bandage for 4-5 days. If the cow's condition does not improve, the symptoms persist and intensify, then you need to unwind the bandage, see what happened to the wound.
It happens that there is a repeated suppuration of the corolla, which has to be opened again surgically.
In parallel with surgical measures, antibiotic therapy (penicillin blockade) and anesthetic (novocaine) are carried out. Intravenous injections are given, as well as blockade with these drugs is performed every 2-3 days: circular (drugs are injected slightly above the inflamed area) or interdigital, less painful (injected into the subcutaneous tissue above the gap between the hooves). Antibiotic therapy should last at least 5 days.
Forecast and prevention
With timely and competent treatment, the cow recovers in a few days.
Ignoring the problem leads to complications:
- inflammation of the hoof joint with accumulation of pus;
- tissue necrosis;
- extensive pododermatitis;
- of death.
To prevent corolla phlegmon, it is necessary to regularly carry out preventive measures:
- inspect the hooves of a cow daily, especially one that came from a pasture;
- identified wounds should be immediately treated with an antiseptic;
- timely clean and trim hooves;
- graze livestock in clean areas where it is impossible to stumble upon garbage and scrap metal;
- do not drive livestock to swampy pastures;
- regularly change the bedding in the stall.
The main conditions for the health of cattle hooves are proper care and quality feeding with the use of additives and vitamins to maintain immunity. Vitamin supplementation is especially important in the winter months, when the immunity of cattle decreases due to a lack of green forage and sunlight.
