WSU Extension programs and employment are available to all without discrimination. Another important scours-causing virus is Coronavirus. Zinc, iron, lead, calcium carbonate and inorganic sulphate are also conditioning factors, which interfere with the absorption of copper. Salmonella species often cause severe diarrhea in calves; many cases are fatal. The first sign of scours is a watery stool, which is usually followed by dehydration. Feces often contain mucous and calves may also show signs of respiratory illness. Some animals are chronic carriers of Salmonella and shed the bacteria periodically in their feces–especially after being stressed by calving, shipping, handling, etc. Infection is by the fecal-oral route. Cattle are housed from November to April and managed so that calving occurs in March or April and then cows and calves are turned out. Neospora caninum is yet another protozoan parasite that can cause diarrhea in calves. Scours can be classified into two types, nutritional and infectious. When in doubt, tube feed. In these cases, commercially available monoclonal antibodies can be given orally to a newborn calf immediately after birth. Types A, B, C, D and/or E may be involved. Neonatal calves are highly susceptible to infectious diarrhea. Bones may be weak and brittle, and easily broken. Scours decreases the ability of the calf to digest milk protein, and it causes the calf to lose appetite, become very weak and run high temperatures. Severely dehydrated and depressed calves may need sterile intravenous, subcutaneous or intraperitoneal fluids to survive. Neonates cannot digest soy or fish-based protein yet. To better understand how these factors can work individually (or in combination with one another) to lead to scours, it’s important to know what defines each. Treatment with electrolytes and Pepto-Bismol® as mentioned above should suffice. The typical carrier: a dairy calf that a beef producer buys to graft on to a beef cow that lost her calf. If the calf is born in winter, it could experience a rapid drop in temperature that can induce stress, reduce its ability to nurse and cause scours. There are a variety of possible causes of diarrhoea in adult cattle and they are often different to the common causes of diarrhoea, or scours, in calves. It has been estimated that 50% of calf mortality in dairy herds is caused by acute diarrhea in the pre-weaning period (Aldridge and Potter, 2011). Calf scours is a common problem for producers, and can be fatal if not caught and treated in time. Some calves may die before they develop scours. A 1:10 solution of bleach is an effective and practical disinfectant, but surfaces must already be soap-and-water clean. This category only includes cookies that ensures basic functionalities and security features of the website. Numerous commercial disinfectants are available through veterinarians, farm supply stores and catalogs. Affected calves are less ill than with Rotavirus and a fewer proportion die. It’s characterized by constant diarrhea, especially with mucus, blood and white or bright yellow feces. Diagnosis is by fecal examination under an electron microscope. Parasites Cryptosporidium spp. These cookies do not store any personal information.

However, antibiotics should ALWAYS be used with caution and only when indicated; injudicious use of antibiotics (especially oral antibiotics) eliminates the beneficial intestinal bacteria that keep pathogenic bacterial numbers in check through direct competition within the gut. All too often you will also bring home  Salmonella, E. coli, or Cryptosporidium parvum. Although E. coli is a normal resident of the intestines, disease-causing variants produce potent toxins that can cause diarrhea, dehydration, shock and death, especially in very young calves. Calves born in winter are often chilled and can be slow to get up and nurse. Calf scour is the most important disease problem in dairy calves and causes more financial loss to the calf producer than any other syndrome. Typically, if a calf contracts non-infectious calf scours, it is due to poor environmental conditions, inadequate nutritional support for the pregnant cow and/or neglect of the newborn calf. It can be diagnosed through a fecal examination. Viruses such as BVD, IBR, Rotavirus and Coronavirus, along with parasites like Coccidia and Cryptosporidium, can induce scours in young cows. Again, a vaccine is available to help prevent scours due to this agent. Birds and rodents can help spread Salmonella around, and warm, wet pasture can remain contaminated for extended periods. This website uses cookies to improve your experience while you navigate through the website. Antibiotics or no antibiotics, that is the question. Oral antibiotics are rarely indicated, recommended or necessary. As with many other types of scours, the. In the case of contagious agents, whether or not a calf develops scours depends on the dose of pathogen ingested as well as the calf’s overall health and immune status. The primary causes of scours include: Rota virus, Corona virus, Cryptosporidium parvum, Salmonella, and Escherichia coli. We'll assume you're ok with this, but you can opt-out if you wish. Clinical coccidiosis can be prevented or minimized by feeding one of the commercially- available coccidiostats in the creep feed or mineral mix. Affected calves are typically between 2 and 12 weeks old, but any age may be affected, including adults. Treating scouring beef calves is a challenge. Get all the information you need about this product on our CattlActive® product page, or contact our team for details. To transition the calf back on milk, bottle feed one quart of cow’s milk or milk replacer, or let the calf back onto its dam briefly. Selenium can be administered by injection to cows during late pregnancy, included in mineral and salt mixes and/or injected into neonates. (1978): Tetany associated with about 4 month of age with clinical signs of muscular magnesium deficiency in suckling beef calves. copper deficiency in cattle on certain areas such as reclaimed peats and pumice soils is well documented. It may be emphasized that these calves had access to both grain and roughage: they were not restricted to milk alone. Unless laboratory work has been performed to diagnose Salmonellosis and determine antibiotic sensitivity, oral antibiotics should NOT be used — they will kill the beneficial intestinal bacteria that compete with. These cookies will be stored in your browser only with your consent. New animals can bring these bacteria into a herd, or a herd may already contain chronic carriers that periodically shed the bacteria in their feces and infect other animals. An anti- toxin is available and can be used to save calves during an outbreak of enterotoxemia. Coronaviral scours usually occurs a little later in a calf’s life than does Rotaviral scours– it is usually seen in calves five days to six weeks old, and most often in calves 3 weeks old or less. Adults in the herd may be subclinical carriers. Typically, calves born in January and February have many more cases of scours than do calves born in April or May. Infectious Causes of Scours in Calves Bacteria such as E. coli and Salmonella can cause scours. The rennin in the calf’s stomach will not be able to clot the casein in the diluted milk, and clotting is a necessary step in the milk digestion process. Some farms and ranches have periodic severe outbreaks of diarrhea in calves due to Salmonella. Scours (calfhood diarrhea) can be caused by viruses, bacteria, parasites, toxins, congenital problems or various nutritional reasons. aborted fetuses, stillborn calves, and fetal membranes. Calves are are week due to inssuffiente production of colostrum. The above condition is known as peat scours Campylobacter jejuni can cause a mild to moderate diarrhea that is often thick and contains mucous and/or blood. References to commercial products or trade names is made with the understanding that nondiscrimination is intended and no endorsement by WSU Extension is implied. for simple copper-deficient pastures). Also, calves are only able to absorb IgG from colostrum in the first 24 hours after birth so if the colostrum is not fed to the calf immediately the calf will not be able to absorb the immunity. Several types are available; some are feed additives and are fed continuously and others are added to the water and administered for 21 days during the period of highest expected incidence. and coccidia are also frequent causes of scours in calves. It should be thoroughly disinfected or at least cleaned, exposed to the sun, limed and heavily re-bedded between uses. Another non-infectious cause of scours in newly born calves is a poorly maintained environment. Also, make sure the product contains at least 20% fat or the calves will not have adequate caloric intake; this is particularly important during cold weather. Bacteria such as E. coli and Salmonella can cause scours. If scours continues, the next meal should be about 3 or 4 hours later and consist of the electrolyte solution again. It is more widely known as an abortion- causing agent. This includes balling guns, OB chains, buckets, milk pails, milk bottles, needles and so on. Calf Scours, or neonatal calf diarrhea, is a problem experienced by most every cowman sooner or later. Special anti-protozoal medication is needed to treat this disease, and this organism can be spread from animals to people. Also, once an animal has been diagnosed with coccidia, consider the premises contaminated for good. In addition to the diseases known under local names, copper deficiency is In some circumstances, your veterinarian may advise a different schedule, such as Clostridial vaccines every six months. Many animals die from this disease; those that survive have short- lasting immunity. Other general recommendations to help prevent scours include ensuring excellent sanitation; practicing effective manure management and removal; minimizing animal stress (such as by using wind breaks, minimizing handling, etc. Also, animals born during inclement weather are often put inside a shelter, where pathogenic organisms accumulate. Protect cattle feed and water from contamination by dog feces, too. Diagnosis is again by electron microscopy and also blood tests. It is not a single disease, but a clinical sign associated with several diseases. Secondary deficiency occurs when there is sufficient Cu available but uptake is reduced due to the presence of ‘antagonists’ (Molybdenum, Sulphur) which … A vaccine is available and may be recommended for herds with a history of this disease. Some producers swear by the effectiveness of certain oral antibiotics to treat scours and it’s hard to criticize what works. Also, milk contains lots of substances that pathogenic bacteria love to feed on. Is it possible to eliminate scours? Depending on the cause, your veterinarian may recommend different treatment and prevention options. If diarrhoea is causing a production loss in your herd, it is important to try to define the problem and then diagnose the underlying cause. Containing copper, selenium, zinc and manganese, it is designed to be administered to stock prior to high periods of demand, such as calving, weaning and mating. A quick word on milk replacers: make sure you use commercial products that are primarily milk protein, not soy or fish protein. Calf diarrhea, also known as scours, is a condition that can be caused by many different factors that can have serious financial and animal welfare implications in both dairy and beef operations. Calves with scours lose many litres of fluid each day as diarrhoea. Pasterns may be upright and the calf seems to be walking on its toes. Affected calves can have a rough coat, pot belly, poor body condition, and permanently stunted growth. This website uses cookies to improve your experience. hits a herd. High mortality isn’t normally associated with a vitamin deficiency in calves, but for one Alberta producer, stressful winter weather may have been the tipping point. Colostrum intake immediately after birth is essential for calf survival. Calves may develop scours due to bacterial or virus infections. In a pinch, this homemade scours treatment can be used: one tablespoon baking soda, one teaspoon salt, eight ounces of 50% dextrose OR 8 ounces of light Karo syrup, and enough warm water to total one gallon of fluid. Once ingested, it can cause abdominal cramps and diarrhea in all mammalian species. Acute cases of peat scour in cattle often responded to a single dose of 3.5 g. of CuSO 4. Infectious Causes of Calf Scours Infectious causes of calf scours may be grouped as follws: Bacterial cause Escherichia Coli Salmonella spp. The products of fermentation make the bowel’s contractions speed up and draw water into the bowel, causing diarrhea. associated with a moderate deficiency of copper (about 7 p.p.m. Refer to WSU Extension publications EB1607 and PNW0157 or your veterinarian for more information on this topic. Our experiments have been carried out to find whether in the herds of beef cattle of north Scotland anaemia, induced by Fe deficiency, was a practical problem. Work with your veterinarian to design specific prevention and control programs for your herd. “Scours is a concern for all dairy producers, but an effective scours prevention program can be simplified into two areas of focus,” says Hill. Heifers may be late reaching puberty and their fertility may be impaired, and cows may be slow to cycle after calving. Work with your veterinarian to collect and submit samples properly. Your Reading List. Try to keep a closed herd. Another predisposing factor is handling or any other practice that keeps calves away from their dams for a long period of time; when the pairs are re-united, the calves may consume too much milk all at once. Secondly, thoroughly sanitize all equipment that you use on animals. The major signs of calf scours include watery stool, sunken eyes, weakness, depression and inability to stand. Newborn calves that are slow to get up and do not respond right away could be affected by a trace mineral or vitamin deficiency. For this reason, calves suffering from scours should be offered a product that corrects dehydration such as Farm-O-San Rediar dietetic complementary feed. Change boots and clothes, wash your hands and disinfect equipment after treating a sick calf. Rotavirus is most common cause of diarrhoea, with over 30% lab diagnoses being rotavirus. On autopsy, the intestines may look purple and contain hemorrhages. Below are some important details about the symptoms, causes, treatment and prevention of scours. After the pairs are reunited, the hungry calves nurse heavily; the consumption of a large meal of milk overwhelms the capacity of the calf’s stomach and undigested milk passes directly through the intestinal tract and causes white scours. Related: Calving Tips For Diagnosing And Treating Coccidiosis In Calves The K99 strain of Escherichia coli (E. coli) causes diarrhea by impairing the ability of the intestinal lining to digest and absorb the milk nutrients. It is caused by protozoal organisms including  Isospora, Eimeria and other species. It usually occurs in individual animals but can occur in outbreaks. Sick calves should be isolated from the rest of the herd, and healthy animals should be tended to first. Wear protective clothing and disinfect all foot gear, clothing and equipment used to treat sick calves. A few other minor causes of scours include various poisonous plants (elderberry, azalea, etc. Unfortunately, Cryptosporidium is resistant to disinfectants and most other practical forms of sanitation. they become older (Smith, 1961). Scours can be caused by any factor that increases secretion of fluid into the bowel and/or decreases absorption of fluid from the bowel. Death is usually due to dehydration, not infection. This important mineral is an essential part of enzyme systems and also contributes to the proper functioning of an animal’s immune system. Scouring calves should receive about one quart of an electrolyte solution every 3- 4 hours, depending on the severity of diarrhea and dehydration. Examples of this scenario include sorting, pregnancy checking, vaccinating, or when a pair becomes separated on the range. Giving probiotic preparations (dried, commercially-available “good” intestinal bacteria) to a scouring calf makes much more sense than giving oral antibiotics. These facts explain why milk is the worst thing to feed to a scouring calf. ), arsenic poisoning, Astrovirus infection, Enteroviruses, cobalt deficiency, zinc deficiency, selenium deficiency, copper deficiency, molybdenum toxicity, mycotoxins, organophosphate poisoning, water toxicity, water deficiency, Chlamydia, Clostridium haemolyticum (“red water disease” or bacillary hemoglobinuria)  Shigella, and Yersinia enterocolitica.

Coronaviral scours prevention is similar to the control of Rotavirus mentioned above. Overeating of milk, grain, fruit, or any other carbohydrate-. There is a swelling of the thyroid gland of the calf, which is frequently referred to as "big neck." Coccidiosis is a common cause of calfhood diarrhea, especially in calves from one to three months of age and/or those just weaned. EFFECT In the early stages calves will show poor appetite and staggery gaits. You have to balance various factors to decide when to calve: earlier calves will have higher weaning weights but greater losses due to scours or pneumonia. Paying inadequate attention to the newborn calf immediately after birth can lead to a poor absorption of colostrum and antibodies within the first few hours after birth. Coccidiostats help control and prevent coccidiosis. Scours can be triggered by a wide variety of factors. Magnesium deficiency in young calves and its management usually, sooner or later, become hypomagnesaemic References (Smith, 1961). Bovine Viral Diarrhea (BVD) is an extremely complicated disease that can manifest itself in a variety of ways in a herd. It is important to check cows and calves at least daily during a calf scour outbreak, as calves can rapidly die from dehydration. The primary causes of scours include: Rota virus, Corona virus, Cryptosporidium parvum, Salmonella, and Escherichia coli. Always thaw frozen colostrum in a warm water bath, not a microwave. Escherichia coli is the most common cause of scours, particularly in calves between one and ten days old. We also use third-party cookies that help us analyze and understand how you use this website. A newborn calf may have scours due to the poor nutrition of the pregnant cow. Keep good records that note which animals were ill, who their dams were, what vaccinations the dams received, what treatments were administered and which treatments were effective. Cattle may develop severe copper deficiency due to excess of other trace minerals such as molybdenum or sulfur. Calf scours (diarrhoea) is the single most important cause of death in milk-fed calves. The stress of cold and wet weather probably contributes to this difference. Generally, immunity increases with the calf’s age and history of colostrum intake but decreases with stress. the „falling disease” in Australia and New Zealand, „reclaim disease” and „peat scours” in Ireland and Canada, and in Scotland „pine” in calves. Some calves may die before they develop diarrhea; others develop colic, become depressed, and may bloat. It is easily treated by common intestinal dewormers, and can be controlled by routine worming and good sanitation/manure management practices. The major bacterial causes of scours include Escherichia coli, Salmonella, Clostridium,  Campylobacter, Shigella and Yersinia enterocolitica. Newborn calves that are slow to get up and do not respond right away could be affected by a trace mineral or vitamin deficiency. The causes of this condition are usually divided into two main groups: the non-infectious and the infectious. An annual booster is needed 2-3 weeks before calving. Contamination can be spread by birds, rodents, flies, feet, buckets, shovels, tires, and so on. Calves that are born with signs of vitamin A deficiency due to abnormal development will probably not benefit from supplemental vitamin A. Abnormal bone development that constricts the optic nerve leading to blindness or muscle incoordination from spine abnormalities will probably not respond to vitamin A.
