Diagnosis and treatment of common physical injuries in dairy cows
The skin is the largest and most exposed organ in the body. Damage to the skin of cattle is more common, especially for cattle raised in rough-designed and overcrowded stables. A humid and dirty environment can also reduce the resistance of cow skin and cause damage to cow skin. If there are insufficient bedding materials in the stables, there are edges or protrusions in the stables that can cause body damage, and the above-mentioned factors can easily cause abscesses or more serious traumas.
Hematoma is often the result of physical damage to the cow. Hematoma is often sudden, painless, soft, fluctuating, and fluid accumulation swelling. Common injury sites occur in areas with more prominent bones and less muscle coverage, such as the protruding part of the pelvis, spine, lower abdomen, and shoulders. Occasionally, hematoma can also spread to the pelvic cavity, leading to increased pressure in the pelvic cavity and interfering with defecation and urination. There are clinical cases showing that the hematoma of the abdomen and flanks of sick cows is caused by other cows after being stuck in the stables (free-range stables). If there is no tissue tear, most of the small hematomas can disappear in white. , Leaving only locally thickened skin. Sometimes the hematoma is infected and transformed into an abscess, and occasionally the hematoma will rupture and release the blood clot. Some diseased Achyranthes bidentata showed obvious skin thickening on the front. Special attention is that the disease needs to be differentiated from abscesses, lacerations of the abdomen, hernias, etc.
Prevention and treatment: Find out the cause of the disease and minimize the occurrence of trauma. The evil is that most cases can be cured, so human intervention should be minimized. Some hematomas can turn into abscesses and require incision and drainage. Occasionally, there are extensive hematomas throughout the body and should be eliminated.
Like hematoma, mucocystitis swelling is a painless, fluctuating soft swelling. However, its development is slower than that of hematoma, and its puncture fluid is a transparent liquid. It can also occur in the hock and wrist when the stables are insufficiently litter.
Treatment: After removing the cause of the disease, bursitis of a single cow is best left to heal. If several cows are sick at the same time, the stables need to be trimmed, such as adding bedding.
Skin abscess is usually hard, high local temperature, mild painful swelling, and its development and enlargement are slow. According to this feature, it can be distinguished from hematoma or hernia (often sudden). A clinical case showed that there was a sterile abscess in the neck of Hayford cattle caused by vaccine injection. Injecting a 40% calcium gluconate solution into the subcutaneous tissue can cause fluid accumulation and form aseptic abscesses after 3 to 6 weeks. The rouge is the site where abscesses often occur. Some affected cows have a large fluctuating swelling on the outside of the left hind knee. Abscesses often occur in the deep muscle layer and can slowly increase over a period of months.
Treatment: The treatment of skin abscess is best done after a part of the abscess wall becomes soft. At this time, it can be cut in a soft place for thorough cleaning and drainage. Repeated high-pressure flushing is also very effective.
The disease may be caused by damage to the horns of other cows, and it also occurs naturally, especially in older cows in the later stages of pregnancy. The disease is prone to occur due to the increased pressure of the abdominal contents.
Treatment: Even with surgery, it is difficult to cure a large hernia in the flank of an adult cow. This type of hernia increases in size at the end of pregnancy and decreases in size after calving. Therefore, it can be considered to be eliminated.
If the ear tag is installed too close to the base of the ear or there is not enough space for the growth of the ear edge during installation, it will cause infection at the ear tag. The area around the ear tag of the affected cow is moist, with purulent exudate and granulation tissue formation. The infection is painful and can easily cause bovine myiasis.
Treatment: Wash the infected area after removing the ear tag, and the affected area will heal quickly.
6. The horns grow to the inside
The horn tip (which has been removed) of the affected cow grows inward and penetrates the skin of the upper eye, forming a painful ulcer wound, and may cause secondary myiasis. Some cases seem to be the result of normal horn growth in older cows, while others are the result of early horn damage.
Treatment: Check the space between the corner of the suspicious case and the skin. Since the corner tip has no sensation, it can be removed without local anesthesia for cases that have caused or will cause damage.
The disease is a group disease of beef cattle, heifers and steers raised on overcrowded slatted floors. The tip of the ox's tail was injured, which was caused by a brutal stepping injury, and then purulent. Suppurative lesions can spread ascending, leading to sepsis in the body and possibly infection of other organs in the body. Some patients suffering from ox tail necrosis lead to ascending infection of Cryptobacillus pyogenes and cause damage to the tail nerve and cause paralysis of the tail. The culprits of the disease are slatted cement floors, enclosed stables, and excessive humidity. In such an environment, when the cow tries to stand, the tail rubs between the hock and the floor several times, causing damage to the tail. Sporadic cases can be seen in dairy farms. The original culprit causing damage is similar to the above-mentioned culprit, and sometimes it can be caused by rough management and Baoding. The disease is easy to diagnose.
Prevention: Take appropriate measures to reduce the crowding of cattle and increase the thickness of litter. Diseased animals should be detected as soon as possible, tail docking should be performed, and antibiotics should be used for treatment.
