When breeding bulls are afflicted with foot rot, there can be negative long-term consequences for the entire herd. Talk to your veterinarian to determine if vaccinating against foot rot infections is a useful prevention method. Foot rot infection demonstrating affected tissue between the claws of the hoof.

Toe tip necrosis is a lameness condition affecting the hind feet of feedlot cattle. It develops early in the feeding period, and often occurs within clusters of animals or cohorts. Sometimes referred to as a toe abscess or ulcer , apical white line disease , or P3 necrosis , it has been associated with improper processing or handling, abrasive flooring, as well as flighty animal behaviour. Careful, low-stress handling and proper flooring may help prevent the development of toe tip necrosis.
The symptoms of toe tip necrosis can be similar to injury, making it challenging to obtain a definitive diagnosis.
It is a very painful conditionas discussed in a recent webinar skip ahead to Recent research found that the disease seems to occur from the outside in. The disease starts when the white line between the sole and the hoof wall separates, allowing bacteria to penetrate into the foot reaching into the corium, which is a very sensitive tissue. Inflammation of the corium causes pain, which is made worse if the infection continues into the foot and infects the P3 coffin bone.
Current research is examining the impact of different treatment protocols for toe tip necrosis on different weight classes of cattle, as well as combining pain relief products.
Carefully trimming the toe tips to allow the infection to drain and reduce pressure on the area is also being explored as a better way to manage the impacts of the disease.

Digital dermatitis, also known as hairy heel wart or strawberry foot rot , is a skin infection that affects the area around the dewclaws, between the claws, and sometimes the heel of the hooves.
The disease is characterized by raised lesions often located between the claws and dewclaws. These lesions are very painful, may appear red and bleed easily if disturbed, and some may have long fibrous hairs. Animals appear to walk on their tip toes to avoid putting pressure on their heels. Once an animal is infected with Treponema , the organism primarily associated with digital dermatitis, the animal will have it for life. To complicate things, digital dermatitis may occur simultaneously with foot rot.
Footbaths can be an effective treatment however there are logistical challenges when trying to use footbaths to treat large numbers of animals. It was long thought that digital dermatitis was only a dairy cattle disease, however it is being increasingly diagnosed in confined beef cattle. A recent webinar discussed digital dermatitis in Ontario, where veterinarians are seeing the disease appear.
This seems to be more common in pack barns compared to slatted barns skip to An animal that has been sick over a longer period of time runs the risk of having the infection spread into bones or joints, making it very difficult to treat. For example, Mycoplasma bovis is commonly implicated in cases of pneumonia and mastitis. Histophilus somni is another organism that has been linked to arthritis.
Unlike M bovis, there is a vaccine available for H somni. Pain management, and in severe cases, euthanasia may be required. Preventing the disease and learning to recognize these animals early on is the best strategy. A swollen joint can cause lameness and become a serious health and welfare problem.
Laminitis is a condition where the lamellae, the layer of tissue between the hoof wall and the coffin bone, is weakened or becomes separated.
Laminitis is linked to rumen acidosis which is when the rumen pH drops causing rumen bacteria to produce toxins that can pass through the rumen wall.
These toxins can cause swelling in the blood vessels of the hooves, leading to founder or laminitis. Laminitis is usually attributed to diets that are high in fermentable carbohydrates such as grain, and it may occur after a sudden or rapid change in rations.
Laminitis may be more common in cattle that are held on feed too long and there is no practical treatment once an animal is afflicted, other than ensuring animals are kept on soft footing in pens that are well bedded. Hoof elongation and curled claws can sometimes accompany severe cases of laminitis or founder. Mycotoxins in feed caused by ergot bodies or other fungi during wet growing conditions can lead to lameness. Ergot restricts blood flow to the hooves and other extremities which can cause severe lameness and even hoof-sloughing or other debilitating health and welfare issues.
These animals often become chronically ill and require pain management or euthanasia. Prevent mycotoxin-related necrosis by feed testing to avoid or dilute mycotoxin-contaminated feeds.
If caught early, this condition can be reversed by removing the contaminated feed source from the ration. Beef cattle may sustain physical injuries, including sprains, breaks, sand cracks, or frostbite. Treatment will depend on the extent of the injury and the course of action should be decided upon in consultation with your veterinarian.
Sand cracks, which are vertical cracks in the hoof wall, are relatively common in range cattle in the Prairie Provinces.
Sand cracks typically heal themselves through thickening of the hoof wall. Environment, exposure to moisture, or heavy animals may be contributing factors to the incidence of sand cracks. If the animal does become lame, further inspection is warranted to treat for possible abscesses or infections. Frostbite most commonly occurs in young animals although older cattle are not immune.
When tissue freezes, blood circulation to the hooves is restricted, and tissue damage — either temporary or permanent — occurs. If the animal recovers from temporary frostbite damage, they can maintain a normal life, but permanent blood vessel damage occurs at a young age and hooves will not grow properly. In these cases, quality of life and production is compromised and euthanasia should be considered. While management and environmental conditions can cause lameness issues, poor foot and leg conformation can also be a result of genetics.
Genetic causes of lameness can be passed down to offspring and are sometimes slow to appear. Just as cows can founder on grass, it is also possible for them to bloat on grass.
According to experts, bloat often occurs due to heavy feeding or grazing period. It is recommended to carefully check cows for bloat every two hours at the onset of grazing.
Other preventive measures are similar to those of lamination or founder. Anti-bloating products are also available. In the past, the dietary requirements of cows were solely sustained by grass. This is no longer the case. While grass can sustain livestock kept for subsistence, commercial cows cannot just eat grass.
To be specific, lactating cows have a high metabolism which can be compared to a high performance athlete. Due to their high metabolism, it is necessary to provide lactating cows with an increased supply of feed in order to achieve maximum production. The modern cow is said to produce about 10 gallons of milk daily. Animals are then forced to deplete their body reserves resulting in tremendous amount of weight loss.
Also, since cows can founder on grass, complementary feed stuff are necessary. An ideal diet for cows should be well balanced. Grass can be ensiled with grain among other materials so as to achieve high yields. Your email address will not be published.

Endotoxins are absorbed into the bloodstream, together with other toxins, such as mycotoxins and exotoxins as well as histamine.
This worsens the blood supply of the lamella tissue, and increases the blood pressure in the feet. Specific cells activate cytokines e. In the worst cases, the connective tissue of the pedal bone completely separates from the lamellar tissue, which causes the rotating, and eventually, the sinking of the pedal bone Figure 3 and 4.
This process causes a lot of pain, and is irreversible. It is important to note that the best treatment is prevention! In acute cases, non-steroidal anti-inflammatory drugs, vasodilators and pain killers are given to the animal. The animal needs to rest on deep and soft bedding material until it has recovered.
In the worst cases, the animal has to be euthanized. To minimise the trigger factors, and therefore reduce the risk of laminitis, some points have to be considered:.
