Many cases of Rotavirus are fatal, and the fatality rate increases with decreasing age. Viruses such as rotavirus and coronavirus, in addition to bacteria are the most important pathogens. Refer to WSU Extension publications EB1607 and PNW0157 or your veterinarian for more information on this topic. (1978): Tetany associated with about 4 month of age with clinical signs of muscular magnesium deficiency in suckling beef calves. It is not a single disease, but a clinical sign associated with several diseases. A quick word on milk replacers: make sure you use commercial products that are primarily milk protein, not soy or fish protein. J. “Scours is a concern for all dairy producers, but an effective scours prevention program can be simplified into two areas of focus,” says Hill. Without lactase to digest it, lactose remains undigested in the bowel and is fermented by bacteria. Newborn calves that are slow to get up and do not respond right away could be affected by a trace mineral or vitamin deficiency. 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. Not only are chilled calves weaker and less likely to ingest adequate amounts colostrum quickly, chilled neonates are not able to absorb colostral antibodies across their intestinal lining. “White milk scours” or nutritional scours is a syndrome sometimes seen when calves and cows are re-united after being separated for several hours. 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. The diarrhea may be bloody, watery, mucousy, foul smelling and may contain shreds of gut lining. Numerous electrolyte powders are available commercially and these should be kept on hand during calving season. Antibiotics or no antibiotics, that is the question. Heavy infestations of the intestinal worm Ostertagia can cause diarrhea, typically in calves over 7 months old. Colostrum given to calves 24-36 hours old is practically useless; antibodies are seldom absorbed this late in life. Cooperating agencies: Washington State University Extension, U. S. Department of Agriculture, and Washington counties. Also, do not change feed types or. aborted fetuses, stillborn calves, and fetal membranes. It may be emphasized that these calves had access to both grain and roughage: they were not restricted to milk alone. Affected calves can have a rough coat, pot belly, poor body condition, and permanently stunted growth. EFFECT In the early stages calves will show poor appetite and staggery gaits. Keeping the cattle pens and calving environment clean is vital to break the fecal-oral contact cycle and, in turn, prevent scours. A test-and- cull program can be repeated in a problem herd until all carriers have been identified and removed. 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. Calves are often quite depressed, lose their appetite and have very watery feces; feces may be discolored yellowish-green. Also, once an animal has been diagnosed with coccidia, consider the premises contaminated for good. The symptoms are similar to those d,escribed above except that the cattle also show severe scours on lush pastures in the spring and to a lesser extent in the autumn. Zinc, iron, lead, calcium carbonate and inorganic sulphate are also conditioning factors, which interfere with the absorption of copper. This in turn decreases the absorption of essential nutrients from milk and leads to … Several strains of another bacteria called Clostridium perfringens produce potent toxins that can cause a severe diarrheal disease known as enterotoxemia. Cattle may develop severe copper deficiency due to excess of other trace minerals such as molybdenum or sulfur. This type of scours can be prevented by vaccinating pregnant cows about a month before they calve and then ensuring colostrum intake, or by vaccinating calves orally at birth. 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. Calves at 4-9months of age are mostly affected but occasionally the disease is diagnosed in adult cattle. ); supplementing with Selenium; culling animals that do not respond to treatment; worming when indicated; preventing overcrowding (especially in the calving area); providing good nutrition; rotating winter feeding sites; and making any ration changes gradually. Through fecal, blood and tissue cultures and more complicated procedures, it is often possible to determine the cause of an outbreak. Cunningham (1950) showed that "peat scours" in cattle in New Zealand occurred on pastures with a moderate excess of molybdenum (2-5-17 p.p.m.) About the only good news with coccidia is that it is species-specific; that is, chickens can not spread their coccidiosis to calves and so on. antibodies by the hour. A muddy or overcrowded lot with viral contamination can lead to stress for the newborn calf. This is one of the very bad bugs you can bring home from the sale yard. An anti- toxin is available and can be used to save calves during an outbreak of enterotoxemia. Nutrient requirements. An antibiotic sensitivity test should be performed at the same time to see if. 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. Escherichia coli is the most common cause of scours, particularly in calves between one and ten days old. Some animals are chronic carriers of Salmonella and shed the bacteria periodically in their feces–especially after being stressed by calving, shipping, handling, etc. 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. It usually occurs in individual animals but can occur in outbreaks. Cryptosporidium parvum, another protozoal organism, is similar to coccidia and can cause severe diarrhea. Infectious Causes of Scours in Calves Bacteria such as E. coli and Salmonella can cause scours. 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. Typically, calves born in January and February have many more cases of scours than do calves born in April or May. Any calf that is sick enough to … Evidence of noncompliance may be reported through your local WSU Extension office. Electrolyte solutions can be given to young calves as their sole nutrition source for a maximum of 48 hours; beyond this period, calves grow weak due to the lack of energy in electrolyte solutions. Vitamin B1 deficiency is a relatively common nervous disease in young cattle. Remember to follow all instructions on the label carefully, including those that pertain to dilution and disposal. Secondary deficiency occurs when there is sufficient Cu available but uptake is reduced due to the presence of ‘antagonists’ (Molybdenum, Sulphur) which … Infection is by the fecal-oral route.
