The course in sheep and goats is rapid, and death may occur 24–48 hr after onset of signs; however, the recovery rate can be up to 30% with prompt, aggressive therapy. A healthy, mature goat rumen should be able to make all of the B vitamins that a goat needs. Treatment. Initial treatment may be administered IV. 1. If cases do occur, in-contact animals should be supplemented with thiamine until normal rumen fermentation is re-established. Goats with polioencephalomalacia who are treated early have a good chance of making a complete recovery. In circumstances when PEM becomes common such as in feedlot lambs that are in transition to a high or exclusively grain diet, the risk may be reduced by providing adequate dietary fiber. Since the animals are generally reared in a non-intensive system there may be a high incidence of Polioencephalomalacia (PEM) in the goats of these areas. Do not administer vitamin B-complex because there is insufficient thiamine to be helpful. PEM symptoms may present itself similarly to listeriosis and even ketosis. As the disease progresses, convulsions may occur, and if untreated, the animal generally dies within 24-72 hours. Additional therapeutic value may be found by administration of anti-inflammatory drugs to reduce brain inflammation along with thiamine administration. © document.write(new Date().getFullYear()) eXtension. Animals occasionally respond rapidly to the initial dose, although slow recovery to standing may take up to 5 days with full recovery evident after 2-3 weeks. Thiamine deficiency reduces energy availability to the brain, which leads to a type of brain degeneration called Polioencephalomalacia ( PEM ) PEM is known as Cerebro Cortical Necrosis (CCN) also PEM is relatively a common nutritional disorder in Sheep and Goats. In cases that are more advanced, thiamine therapy may not be able to overcome brain trauma that has occurred and euthanasia may be indicated. Metabolic means relating to metabolism, the whole range of biochemical processes that occur within the goat's rumen. Blindness may be permanent in these animals. COMMON EYE PROBLEMS IN GOATS. Treatment: Thiamine is the only effective therapy, and treatment can result in improvement within two hours if the disease is caught early. Treating goat polio is done through dosing high amount of thiamine. It is a nutritional /metabolic disease that affects primarily ruminants, including goats. MSU is an affirmative-action, equal-opportunity employer, committed to achieving excellence through a diverse workforce and inclusive culture that encourages all people to reach their full potential. Prevention of enterotoxemia is far more likely to be successful than trying to treat the disease.Enterotoxemia is a frequently severe disease of sheep and g… Thiamine is a B vitamin (vitamin B1) that plays a critical role in all cells, acting as a cofactor for several key enzymes involved in glucose metabolism. Therefore, animals on amprolium therapy should be watched carefully for polio. It is usually found in baby goats that are one to two weeks old. 3 PEM ‐Treatment • Thiamine (vitamin B1) • 10 to 20 mg/kg bw IM or SC TID for 3 days • Injectable products vary in concentration (75 mg/mL to 500 mg/mL) • If treat early – response seen within a •few hours • If no response in 24 hrs, likely will not • Flock level … A supplementation of thiamine in the goat feed may decrease the chances of the occurrence the disease. Sheep and goats also consume cruciferous or brassica forages such as turnips, rape, mustard and oil seed meals; products which can be high in sulfur as well. Cases of PEM can be successfully treated if detected early in the disease course, making recognition of early symptoms a critical issue for sheep and goat producers. This may also be associated with unilateral (uneven) ear droop and/or unusual/exaggerated gait. It does however also occur in adult Angora goats. Treatment may not be successful in severe cases. The sulfur content of these feeds may vary according to the processing plant or even the batch, as much of the additional sulfur content in these by products results from addition of acidifying agents such as sulfuric acid during the production process. ... “Polioencephalomalacia (Goat Polio)” Alabama and Auburn Universities UNP-65 – Maria Leite-Browning, DVM, MS Extension Anima Scientist Alabama A&M University. Amprolium effectively competes with thiamine for uptake into the brain which therefore can induce PEM. As with many disorders and disease conditions, early detection is key for successful treatment. Polioencephalomalacia is a neurologic disease of goats associated with severe metabolic imbalances. This information is for educational purposes only. Since the brain controls nearly all bodily functions, adequate thiamine levels in the brain are of critical importance for normal health and well-being. A common name for this disease in sheep and goats is “polio”; however, it has absolutely no relationship with the infectious viral disease found in humans (poliomyelitis). In some cases, both eyes are affected. Effective but slightly more risky therapy would be to inject the first dose slowly intravenously (IV) followed by another dose provided intramuscularly (IM). Many cases of PEM response to prompt administration of thiamine (minimum dose of 10 mg/kg bodyweight). Entropion causes the lashes to rub on the eye and cause watering, irritation, and damage to the eye, if not corrected. This image shows a lamb with advanced PEM symptoms: head arched and unable to stand. In Thiamine is a B vitamin (vitamin B1) that plays a critical role in all cells, acting as a cofactor for several key enzymes involved in glucose metabolism. Entertoxemia is a frequently severe disease of sheep and goats of all ages. Jeffrey W. Dwyer, Director, MSU Extension, East Lansing, MI 48824. The dosage of thiamine is 10-20, mg/kg, IM or SC, tid. Mocha unfortunately contracted Listeriosis - thankfully we caught it early and were able to start treatment early. The first dose is administered slowly IV; otherwise, the animal may … Whether as a refresher on knowledge you already have or adding to your Multiple doses (0.25cc/10-pound body weight three to four times day) of thiamine and other actions based on veterinary recommendations are required for best outcomes; these recommendations will vary based on the underlying cause of the disease. 4. Encephalitis is the most readily recognized form of listeriosis in ruminants. During an outbreak, sufficient roughage should be provided. Polioencephalomalacia (PEM), also referred to as cerebrocortical necrosis (CCN), is a neurological disease seen in ruminants that is caused by multiple factors, one of which is thiamine depletion in the body. Polioencephalomalacia (PEM) is also known as cerebrocortical necrosis (CCN) and is a relatively common nutritional disorder in sheep and goats. Lame sheep and goats spend more time lying down or grazing … Caseous Lymphadenitis (CL) is a chronically infectious disease of sheep and goats that is caused by the bacterium Corynebacterium pseudotuberculosis. This leads to huge economic losses to the tribals which is why knowledge about this >>> In these cases, the first action should be to increase dietary fiber as a preventative measure. Reference to commercial products or trade names does not imply endorsement by MSU Extension or bias against those not mentioned. This is the same lamb 4 days after a daily thiamine therapy regime. Polioencephalomalacia (polio) in ruminants is caused by a thiamine deficiency and/or sulfur toxicity. Polioencephalomalacia (PEM) - caused by Vit B1 (Thiamine) deficiency simply literally means softening of the brain. Another cause of PEM documented much better in cattle is excessive sulfur intake from sources including water, feed ingredients and forage. Thiamine deficiency reduces energy availability to the brain, which leads to a type of brain degeneration called polioencephalomalacia or PEM. It is critical to keep to this 24-hour cycle of medicating the goat. If the problem can be associated with a high sulphur intake, all possible sources of sulphur, including water, should be analysed and the total sulphur concentration of the consumed dry matter estimated. MSU is an affirmative-action, equal-opportunity employer. Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. For additional information on other brain disorders please click the link: http://www.extension.org/pages/22450/goat-cns-diseases. Thiamine is not produced in animal cells but is produced by rumen microbes, which provide the major source of thiamine to adult sheep and goats. Animals with PEM may take several days to stand on their own, so it is important isolate all cases and provide supportive care to encourage water and feed consumption (provide both grain and forage free choice to encourage standing and feed consumption). Although dietary supplementation of thiamine at 3-10 mg/kg feed has been recommended for prevention, the efficacy of this approach has not been carefully evaluated (The Merck Veterinary Manual, 2006). Therefore, it is difficult to develop an effective prevention program for these cases, although making gradual dietary transitions will certainly reduce the incidence of PEM along with many other health concerns. 2020-41595-30123 from the USDA National Institute of Food and Agriculture. It is common for the pupils to be dilated and for the eyes to tear. Animals will show improvement within minutes or a few hours. If brain lesions are particularly severe or treatment is delayed, full clinical recovery may not be possible. The disease is seen more in winter in North America, primarily due to increased grain feeding to meet increased maintenance energy needs. Addition of feed grade thiamine can also be made to the diet, but this therapy can be expensive and its efficacy has not been thoroughly evaluated in growing lambs or kids. Moldy feeds and high-carbohydrate feeds should also be minimized. Elevated dietary sources of sulfur in sheep and goat diets include by-product feeds of the ethanol industry such as wet or dry distiller’s grains with solubles. Most cases of PEM are isolated and sporadic in nature and are associated with changes in feed of some sort. Antibiotics may be indicated depending on the underlying cause. Thiamine is especially important for proper brain function as the brain relies on glucose as its major source of energy. The most common cause of PEM is thiamine deficiency. Administer thiamine HCl in the dosage of 4.5 to 10 mg/lb intravenously. Multiple doses (0.25cc/10-pound body weight three to four times day) of thiamine and other actions based on veterinary recommendations are required for best outcomes; these recommendations will vary based on the underlying cause of the disease. Concentrated formulations of thiamine are a prescription product, so be sure to work with your veterinarian on any PEM treatment program. Thiamine, also known as vitamin B1, is normally produced by bacteria in the rumen of cattle and sheep on well-balanced roughage diets. It affects all ages and both sexes, sometimes as an epidemic in feedlot cattle or sheep. It is a disease that is seen more commonly in Angora kids grazing lucerne lands or fed concentrates especially if containing molasses. Producers should work with their DVM to specify a treatment plan and to be sure to have a bottle of concentrated thiamine on hand at all times. Since the brain control… Other causes include improper feeding, feeding too much grain, or anything that disrupts the health and well being of rumen microbes, such as chronic or acute acidosis or indigestion. Early blindness symptoms lead within hours to a day to loss of body control, inability to stand, and seizures. The usage of these sulfur-rich products varies across ethanol plants, so blanket statements regarding ethanol by-product feeds as being high in sulfur cannot be made. The proportions of mortality in goats and sheep were 49.2 and 42.9%, respectively. The lamb recovered completely in 2 weeks and is now a productive, 4-year-old ewe. The symptoms matched up with Polioencephalomalacia (PEM). PEM is also found in adult small ruminants of either sex at any age but more commonly associated with changes in diet (change in the plane of nutrition, pasture type, pasture to forage feeding, forage feeding to grain addition, etc.). Supplementing by feed is not fast enough. The ideal treatment for polio in goats is the administration of thiamine at the dose of 10mg/kg thrice a day. Prevention should also include avoidance of sudden dietary changes to energy dense feedstuffs. Observe young goats for possible coccidiosis symptoms by Mike Metzger Drug Withdrawal Withdrawal interval recommendations - Food Animal Residual Avoidance Databank (FARAD) recommended withdrawal times for extra-label use of a select number of drugs used in sheep and goats Causative bacteria are present in relatively low numbers and appear to be in a relatively quiescent state in the normal, healthy animal. Goat Polio www.jackmauldin.com The official name for Goat Polio is "Polioencephalomalacia". The 4-H Name and Emblem have special protections from Congress, protected by code 18 USC 707. Goat Management (Dairy, Meat, Record Keeping), http://www.extension.org/pages/22450/goat-cns-diseases. But then as they transition to becoming ruminants, they rely on their rumen microbes to synthesize thiamine as their thiamine source. If the neurologic examination indicates brain involvement, polioencephalomalacia, listeriosis, and rabies should be considered as possible causes. In delayed diagnosis and treatment, full clinical recovery may not be possible. In high-risk herds where animals are on high grain diets, supplementation with thiamine mononitrate, probiotics or brewer’s yeast may be indicated for prevention. It was so easy and so … Severe thiamine deficiency can possibly kill a goat in 24 hours to a few days if left untreated. However, thiamine therapy is relatively benign, so it is best to treat with thiamine as a precaution. Even a change in diet, if given too quickly can throw the rumen off enough to cause a vitamin deficiency. Thiamine deficiency and/or high sulfur levels within the brain cause destruction of neurons and swelling of the brain which can be diagnosed by histological examination of brain tissue. Cases of PEM can be successfully treated if detected early in the disease course, making recognition of early symptoms a critical issue for sheep and goat producers. Results: The majority of seizures in goats and sheep had structural or metabolic causes. 2. Entropion (or inverted eyelids) is a condition in which the eyelid—usually the lower eyelid—is turned inward. Die… Michigan State University Extension programs and materials are open to all without regard to race, color, national origin, gender, gender identity, religion, age, height, weight, disability, political beliefs, sexual orientation, marital status, family status or veteran status. Milk-fed lambs and kids must get thiamine preformed from their diet to meet requirements. Thiamine is a key chemical in glucose metabolism that, when deficient, is most threatening to neurological activity.
