Hoof Care—Treatment and Prevention

Tutorial Video on Sheep TrimmingSusan Schoenian, Sheep & Goat Specialist, University of Maryland Small Ruminant Extension Program (Previously shared on Premier1Supplies Sheep Guide) Hoof care is one important aspect of sheep production and management. Hoof diseases can affect the health and welfare of sheep and have a negative impact on performance. Hoofs should be checked regularly for disease and excess growth. Animals with overgrown nails, recurrent nail problems, and/or unresponsiveness to treatment should be euthanized.Nail trimming Nail growth – and therefore the need for nail trimming – is influenced by many factors, including breed and genetics, soil moisture and characteristics, management and nutrition. Sheep raised on dry, rocky soil may not require the same level of hoof care as sheep raised on more humid, rock-free soil. Sheep in areas with heavy rainfall will need their hooves checked more often than those on dry ground. Indoor sheep often require more hoof trimming than those kept indoors. Sheep in higher trophic levels generally require more frequent hoof trimming. Conventional manual scissors are inexpensive and make the job a lot easier. Air compressor shears are an option for those with a large number of sheep. A sharp paring knife is required to remove pockets and perform a more thorough nail trimming job, especially when disease-causing organisms are present. There are different types of sheep handling equipment that can house sheep for easier access and trimming. The tilting or flipping table will hold the sheep upright or on its side. Manual and automatic (electric) tilt tables are available. A tall platform with a head gate can also house sheep for hoof trimming, as well as other management duties. A sheep or deck “chair” is a less expensive way to house a sheep for hoof trimming. In the absence of specialized equipment, sheep often lie on their backs to trim their hoofs. To trim the legs, hold the sheep’s feet firmly. Inspect the foundation and remove mud, feces, or small stones between the nail walls. A rotten smell is often a sign of foot rot. Use a knife or scissors to remove all debris and debris from the nail. After cleaning the nail, start trimming around the nail circumference, avoiding cutting off large sections of the nail. Let’s stop at the first sign of rosy. Pink means you’re getting closer to the blood supply to your feet. Feet should be trimmed from heel to toe to remove excess growth of the “horny” portion of the nail. To find out what properly trimmed hooves look like, study the paws of a newborn lamb. Its nails are flat at the bottom and boxy, when trimming the legs, avoid stressful times like hot weather or late pregnancy. You should combine nail trimming with other management tasks, such as trimming or vaccinations. It will be easier to trim hooves that have softened due to frost or heavy rain.Diseases affecting the nails The limp should never be overlooked. It can be a sign of a number of foot problems – some very serious – as well as a number of other problems. by insect bites. A red to brown band around the rim of the ear is an important diagnostic sign of bluetongue. Foot abscesses are caused by a bacterial infection in damaged foot tissues. The forefoot is most commonly affected. Usually only one nail is infected. Treatment is usually with antibacterial compounds. Foot-and-mouth disease (FMD): Foot-and-mouth disease is a highly contagious viral disease that affects pigs, cattle, sheep, goats, and deer. It is endemic to many parts of the world. Clinical signs of disease in infected animals include blisters or sores on the mouth, snout, tongue, gums, nipples, or around the tips of the feet. Signs of FMD in sheep and goats are often much less obvious than in cattle or pigs. . Canada has been free of foot and mouth disease since 1929. The UK experienced a foot and mouth disease outbreak in 2001.Foot disease Foot rot is one of the worst diseases in the US sheep industry. While footrot is not lethal, it can cause premature destruction of animals. The cost of treatment, especially labor, can also be huge. Footrot is a popular reason to get out of the sheep business. While F. Necrophorum is found in soil and faeces and is present wherever sheep, goats, and livestock are present, the organism B. Nodusus often “walks” onto farms in the hooves of infected animals. sick. There are more than 20 strains of B. Nodusus, which vary in their infectivity and severity. Warm water, mud, and poor sanitation are favorable environmental conditions for the spread of foo trotters, once the bacteria have been introduced to the farm. Wet conditions create the anaerobic (lack of oxygen) conditions necessary for the spread of disease. However, B. Nodusus bacteria will only live in the soil for 14-21 days. The bacteria that cause foot rot, button Bacteriodes, are spread from infected sheep to the soil, manure, litter, etc., after which they are picked up. because sheep are not infected. Foot rot occurs when purchasing an infected animal or simply using vehicles or trucks that have been infected by infected sheep. Since the organism does not survive long in the environment (<2 weeks), carriers in the herd will continue to re-infect the herd unless the animal is culled or the organism is eliminated with appropriate treatment. a herd perspective. Since the organisms that cause foot rot are anaerobic, introducing oxygen into their environment will help eradicate them. Therefore, it is important to have the proper hoof trimming; However, care must be taken not to cause bleeding. Removing overgrown toenail tissue will help produce less sludge and packed manure, which in turn supports environmental conditions conducive to leg growth. After foot trimming, regular foot baths in zinc sulfate (10% weight/volume) foot bath can be of great help in eradicating this disease. is recommended, as it is believed to help spread the disease. Instead, antibiotic injections and antibiotic sprays are recommended to control nail rot and similar nail diseases. European researchers have successfully treated foot rot with Gamithromycin (Zactran®), a macrolide antibiotic licensed for cattle for the treatment and control of respiratory disease in cattle. cases. However, just because a sheep is immunized against foot fungus does not mean it is immune to the infection. The vaccine does not cover all strains of foot fungus. Vaccines are not always available. Breeders with clean herds can more economically control foot fungus by prevention than by vaccination. There may be a genetic susceptibility to footrot; Some sheep are more susceptible to footrot than others. In addition, there may be dog breed variations in susceptibility to footrot. Therefore, sheep that are resistant to foot fungus should be bred, while those susceptible to the disease should be culled. Keeping records can help identify these types. In general, black hooves are harder than white hooves. Preventing foot rot is much easier than eradicating it. Several management practices help reduce the chance of foot rot on its own in the herd. You should never buy sheep infected with foot rot. Avoid buying clean sheep from an infected flock. Avoid buying sheep from barns where clean and infected sheep are housed together. Always isolate new animals for at least 30 days. Cut off your legs as soon as you get there. Treat the new sheep's legs after trimming. Recheck your feet during quarantine.Scalp of the feet (dermatitis between the cervical vertebrae) Burns of the feet is an infection of only F. colirophorum and is not contagious. Burns to the feet cause lameness, usually on the forefoot, and lesions are found between the hooves. Tissue between the toes of scalded sheep is generally white and white, or red and swollen. Foot burns are much easier to treat than foot rot. Many times, placing sheep in a place with drier feet and no mud will alleviate disease problems. The simplest and most effective treatment is to use a foot bath containing 10% zinc sulfate solution (8 lbs. Zinc sulfate to 10 gallons of water). The frequency and severity of foot infections will decrease as the weather gets drier. Animals usually die before legs are involved. Recovered animals may exhibit abnormal foot growth and/or be permanently lame. Blisters also appeared on the mouth and other areas of the sheep’s body. Infections are more common around the mouth than on the legs or feet. Lesions can be treated with ointments containing broad-spectrum antibiotics. Soremouth can be prevented by vaccination.
