The sheep must be adequately restrained for the injection procedure, usually in a race or small pen. Scald is not invasive, and causes no separation of the horn from deeper tissues. If done correctly, this will restore the foot to near normal (Scott and Henderson, 1991). Lameness can cause huge welfare and economical problems in flock: an animal in pain will spend less time feeding and grazing and more time lying down with decrease in body condition, lower lambing percentages, reduced growth rates in lambs, poor fertility in rams and many more. Careful foot paring may prevent shelly hoof becoming infected (Scott and Henderson, 1991). Lambs less than 10 kg 21 gauge 5/8 inch. A separation of hoof horn, starting in the interdigital space. Forage and grazing being the main source of nutrients for ruminants, and continuously available to non-ruminants. By 12am. Once D. nodosus is established, F. necrophorum can advance deeper into tissues too, where it will contribute to further inflammation and tissue damage, caused by the action of its exotoxins. Reduce high stocking densities- this decreases your chance of damp bedding and infection spread. A practical and economical method to increase lamb production. The plan should assess vaccination policy, control of internal and external parasites and foot care as a minimum. If the build-up of pus does occur, the treatment is the same as for toe abscesses. Use of a sterile 17 gauge 1 / … For control programmes to be effective it is essential that the pathogenesis and epidemiology of foot-rot is understood and that control methods are implemented at appropriate times in the season, depending on climatic and pasture conditions (Abbott and Lewis, 2005).

Foot abscesses can form in the deeper parts of the hoof and often affect the pedal joint. Using breeds and strains well-suited and adapted to the prevailing conditions. Lameness in sheep is a common and persistent disease, reported in flocks in all sheep producing countries. The foot is often so badly damaged that the horn does not grow back properly. Click here to read about the control and prevention of granulomas. Housing increases the spread of the disease, therefore sheep should be free of foot-rot when brought-in. In chronic cases, the hoof walls and toes become overgrown and misshapen, trapping dirt and inflammatory exudate between the inflamed, granulating soft tissues of the sole and overgrown horn. The best time to start an eradication programme is in summer, after weaning and before tupping. Western Australia has predictable periods of hot, dry weather, with a typical low rainfall period from spring through to the end of the summer, which naturally prevents survival, thus transmission of virulent D. nodosus (Green and George, 2008). See Control and Prevention of Scald and Foot-rot for more information. XL Vets have also been running a “Stand up to lameness” campaign for the past 2 years across the UK, please click here for details. As scald infection is superficial, the animals do not have to stand in the footbath for very long. Click here to read about the control and prevention of CODD. Contains polyandroalbumin . Most granulomas are caused by over-trimming the feet, however chronic exposure to moist conditions and previous footrot have been suggested to be major contributing factors to granulomas (Egerton, 2007). Drugs can play an important role in preserving the health of individual sheep and the flock as a whole. Click here to read about the control and prevention of foot abscesses, A granuloma is a strawberry-shaped area of proud flesh, which grows at the site of damage to the foot. Click here to read about the treatment of CODD, Image courtesy of Duchy College Rural Business School. Priority. Wet conditions soften the inter-digital space making it more susceptible to bacterial penetration. If foot-rot is present on the farm, but only small numbers of sheep are affected in a group, these can be treated with coloured oxytetracycline (antibiotic) spray, provided the treated animals are not immediately returned to wet grass (Harding et al., 1981). £0 - £149.99. Therefore, vaccination should be avoided within 6 – 8 weeks of shearing or 6 months before sale or showing (The Veterinary Formulary, 1998). It contains 1%w/v doramectin (10mg/ml). D. nodosus cannot invade the dermis without prior damage to the foot (Beveridge, 1941) and it cannot persist in the environment for longer than 7-10 days under optimal moisture and temperature conditions. Routine feet inspections will pick up any cases of shelly hoof early. Lameness varies from mild and transient, to severe and persistent (Egerton, 2007). Lameness in sheep is a major welfare problem and affects two of the Five Freedoms promoted by the Farm Animal Welfare Council, as it not only causes pain to the animal, but can also cause a depression in feed intake. Prickly pasture should be avoided, as this may cause interdigital abrasions, predisposing the interdigital skin to infection (Whittington, 1995). Persistently infected sheep, which do not fully respond to treatment, should be culled as they are a constant source of infection. Tilmicosin (Micotil) is often found to be more effective than oxytetracycline during the acute phase of CODD. If foot trimming is necessary, make sure the clippers are sharp and are disinfected between feet to minimise the spread of any bacteria, also collect and dispose of any hoof clippings as they can harbour harmful bacteria such as D. nodosus. Where resistance exists, protection periods may be shorter than those stated. The affected claw becomes swollen and very painful, with visible signs of necrosis. It becomes swollen, sore and inflamed and covered by a thin layer of white material There is no under-running of the hoof wall and no foul smell although sheep can appear quite lame with this condition. Difficult cases may need poulticing for a couple of days to soften the horn and speed recovery. Sometimes pus will be released. The greatest risk of a CODD outbreak in a flock is from bough-in stock. It is often caused by over rigorous foot trimming, which has led to bleeding, although other causes of injury to the foot may play a role. Preventing scald helps prevent foot-rot. The first problem is an extensive degeneration of the white line. Pus forms and the animal becomes acutely lame. Peaks occur normally between April and June then again later between August and October in the UK. IVOMEC Classic Injection for Cattle and Sheep should be given only by subcutaneous injection at the recommended dosage level of 1ml/50kg bodyweight under the loose skin in front of, or behind, the shoulder in cattle and over the neck in sheep. Walking sheep through foot baths 6m long, 10cm deep containing 10% zinc sulphate heptahydrate or 3% formalin should be adequate (Egerton, 2007). An easy and simple injection; Contains polyandroalbumin; RECOMMENDED FOR. Foot-rot is a complex, highly contagious disease caused by a synergistic infection of two anaerobic bacteria, Dichelobacter nodosus and Fusobacterium necrophorum, and has a characteristic foul-odour, often accompanied with a grey pus (Green and George, 2008). There is often rapid shedding of the whole horn case, leaving a raw digital stump. This does not usually cause harm so foot trimming is unnecessary, unless the hoof horn is severely overgrown and the sheep is lame. A maximum of 20-25 sheep should be injected with one needle before it is changed (this number will often correspond to the number of doses in the bottle). Delivery & Returns . Topical treatments, vaccination and parenteral antibiotic therapy all have a role in treating sheep with advanced foot-rot infections, but prevention of severe infections is best achieved by the timely implementation of control programmes. During the wetter autumn and winter, farmers undertook the basic control and treatment measures for virulent foot-rot, including foot bathing, topical antibiotic treatments and vaccination. This should be developed with appropriate veterinary and/or technical advice and reviewed and updated annually. Refrigerated items. Control depends on purchasing all sheep from known sources and/or health status to reduce the risk of infection, isolation of all purchased sheep for at least 30 days, regular inspection of all purchased sheep during the quarantine period, and the isolation of any sheep found to be lame and prompt treatment with a suitable antibiotic recommended by your veterinary surgeon. It is usually found in sheep that are continuously exposed to wet pastures (Egerton, 2007). F. necrophorum infection on its own causes a condition called scald, strip or ovine interdigital dermatitis (OID) and it affects the skin between the claws only, in the interdigital space. Lameness in sheep is a significant cause of financial losses with an estimated cost to the UK industry of £28 million per year. If both front feet are affected, animals will walk on their knees.

Sheep and goats. The damage to the skin from scald, however, allows D. nodosus to invade and colonise deeper layers, where it feeds on collagen. Affected feet have a very characteristic foul smell. Adequate straw bedding should be maintained to keep feet dry and clean and lime spread on the floor, especially around water troughs, will help dry and sterilise the bedding and reduce the risk of infection (Henderson, 1990). 2016). Standard. £12. Persistently infected sheep need to be identified and those that do not fully respond to treatment should be culled, as they are a source of infection to the rest of the flock. Undertaking good practice with regard to biosecurity. Sort sheep upon inspection into infected and uninfected groups. Cydectin 2% LA Sheep Injection . Intravenous injection in cattle or sheep will be fatal. In contrast, foot-rot can be eliminated from a flock, as D. nodosus can only survive for 2-3 weeks on pasture. Tracks such as the one in this image are much softer on the feet. Farmers Weekly, AHDB Beef and Lamb and MSD Animal Health have put together a useful ‘Five Point Plan’ to tackle lameness, which incorporates reducing disease challenge, building resilience and establishing immunity. Foot-rot has been estimated to cost the UK sheep industry £24 million annually (Nieuwhof and Bishop, 2005). Once infection is established in the joint, permanent damage is inevitable. It should be noted that once vaccinated with footvax, these animals cannot be treated with 1% moxidectin I the future. It works on natural principles to increase the ewe’s ovulation rates. (This table has been adapted from Egerton, 2007 p273 Table 39.1). The infected group must be kept separate from the uninfected group, so that treatment can be repeated every 2-3 weeks until the animals are cured, Flocks with a severe foot-rot problem may benefit from vaccination to reduce the number of infected sheep. 1. £20. There are also many other reasons for lameness including: It is no longer advised to routinely trim diseased and healthy feet as it is have been shown to exacerbate foot-rot and scald (Green et al., 2007). ** Known as contagious foot-rot in the USA. Housing increases the spread of bacterial lameness infections. As foot-rot is a major welfare concern, a strategy to reduce lameness should be a priority and part of every farm’s Flock Health Plan. Skin in between the claws is affected. Treated animals should be turned out on grazing which has been free from sheep for at least two weeks. Some field studies have shown that a longer protection period may be achieved. £450 or more. Further paring may have to be carried out to remove underrun horn as the hoof heals, though carefully and not excessively. There is also information about the techniques including illustrations, descriptions and tips. The overlying horn is unable to grow back normally. Mild cases, not necessarily leading to lameness, are very common. Photograph by Mike Suarez. On some occasions the wall horn curls over the sole horn. The horn should not be pared so deeply that bleeding is caused. Improved understanding and responsible usage of veterinary medicines. Human Warnings: Not for human use. Routine foot bathing is useful to treat and prevent scald, but unless the animals stand in it for 15 minutes at a time, it is not particularly effective in treating foot-rot. Avoid the use of mutilations as standard production practices. Long-acting oxytetracycline is very effective in treating the disease and requires less handling than short-acting oxytetracycline (Grogono-Thomas et al., 1994). In the case of foot-rot, the animals need to stand in the foot bath much longer (10-15 minutes), but as this is not always practical, infected and uninfected sheep should be sorted and treated separately. These lead to lambs suffering hunger, hypothermia and disease (Harwood et al., 1997). Infection starts at the junction of the coronary band and the wall of the hoof, and infection invades the sensitive laminae underneath the horn (Egerton, 2007). It has previously been suggested that flocks badly affected with footrot or CODD could use blanket Tilmicosin treatment metaphylacticly. Antibiotic Tubes . There are no anti-inflammatory drugs licensed for sheep so vets are allowed to prescribe cattle drugs under the cascade system. Having a closed flock can make it easier to eradicate foot-rot from the flock and keep the flock free from the disease, additionally, the reduced stocking rates will decrease the foot-rot challenge. Any bought-in sheep need to have their feet checked and bathed upon entry to the farm, These sheep need to be grazed separately for at least 3 weeks, and foot bathed again before entering the main flock, Livestock should be land-based and integrated with farm cropping enterprises, Animals should be provided with conditions that enable them to exhibit natural behaviours, Dependency on veterinary medicines should be reduced without jeopardising the well-being of animals, Reducing dependency on veterinary medicines without jeopardising the well-being of animals. Use of a sterile 17 gauge 1 / 2 inch (15-20 mm) needle is suggested. It is commonly spread in warm, damp conditions during grazing periods. Penicillin Injectable Indications Penicillin Injectable is indicated for treatment of bacterial pneumonia (shipping fever) caused by Pasteurella multocida in cattle and sheep, erysipelas caused by Erysipelothrix rhusiopathiae in swine, and strangles caused by Streptococcus equi in horses. A break occurs at the skin horn junction from where infection spreads under the horn tissue so that the wall of the hoof becomes separated and the sole under-run. 8 Signs A grey, oozing pus with a distinctive foul smell. Preferred injection sites for intramuscular injections are: The side of the neck, 10-15cm in front of the shoulder in the mid neck area well above the large jugular vein. Outbreaks of scald (OID) are typically seen in lambs on pasture and among ewes housed on straw. We now hold FREE Weight Loss Clinics for your pets. This will prevent the transmission of D. nodosus, the virulent bacteria that causes foot-rot. At concentrations greater than 5%, formalin can cause severe irritation of the interdigital skin. necrphorum is thought to have a higher pathogenicity than the subspecies funduliforme, which may tell us more about the involvement of this bacteria in the complex (Maboni et al, 2016). Footrot is very common condition, it is extremely painful and very contagious. Prevalence of toe abscesses in flocks is usually very low, and is non-infectious. Animals having outdoor access, shade, shelter, lighting and sufficient space for them to undertake free movement and to exhibit natural behaviors. Regular foot bathing throughout the housed period should prevent an outbreak of foot-rot. Recording which animals are persistently lame and do not respond well to treatment, is crucial in controlling infectious lameness in a flock. Identification of high-risk periods for disease will encourage quick implementation of control strategies. The information is supplied without obligation and on the understanding that any person who acts upon it, or otherwise changes his/her position in reliance thereon, does so entirely at his/her own risk. Some animals suffer repeated attacks, probably due to a permanent defect in the horn. The animal may become permanently lame due to a permanent deformity (Egerton, 2007).
