Ketosis In Cattle Symptoms And Treatments

Ketosis In Cattle Symptoms And Treatments

Ketosis is a fairly common disease among adult cattle, although usually it occurs in dairy cattle.Ketosis typically occurs the first six weeks of parturition.It occurs in dairy cattle because of their inability to intake enough nutrients to meet their energy needs.This can lead to hypoglycemia which is a pathologic state produced by a lower than normal level of glucose.That in turn leads to the formation of ketone bodies from the body and fat stores. Although they are only broken down for energy to used by the heart and brain in the times of low glucose levels. Ketosis is not an immediate thing like many other illnesses, it gradually occurs. Some typical symptoms you will notice about your cattle if they have ketosis happen to be a decreased appetite,marked weight loss,decreased milk production,acetone odor of breath,nervousness, and hard, mucus covered feces. For confined cattle, usually decreased appetite is the first sign that they might have ketosis.Also if they are fed in components such as part forage, part grain, they will tend to go for the forage more than they will go for the grain.If you fed your cattle in herds, then usually you will see reduced milk production,lethargy and an somewhat “empty” appearing abdomen.When cattle are physically examined with having ketosis they may appear sightly dehydrated. Treatment for ketosis in cattle is more commonly done by IV administration of 500 ml of 50% dextrose solution. This treatment allows rapid recovery but the effects are often producing results beyond itself therefore relapses of ketosis are pretty common.Another treatment that can be used is the administration of glucocorticoids such as dexamethasone or isoflupredone acetate.You typically administer 5-20mg dose intra muscularly. This treatment often has good Continue reading >>

What Is Ketosis Diet And What Does It Contain?

What Is Ketosis Diet And What Does It Contain?

A keto diet is well known for being a low carb diet, where the body produces ketones in the liver to be used as energy. It’s referred to as many different names – ketogenic diet, low carb diet, low carb high fat (LCHF), etc. When you eat something high in carbs, your body will produce glucose and insulin. Glucose is the easiest molecule for your body to convert and use as energy, so it will be chosen over any other energy source. Insulin is produced to process the glucose in your bloodsteam, by taking it around the body. Since the glucose is being used as a primary energy, your fats are not needed, and are therefore stored. Typically on a normal, higher carbohydrate diet, the body will use glucose as the main form of energy. By lowering the intake of carbs, the body is induced into a state known as ketosis. Ketosis is a natural process the body initiates to help us survive when food intake is low. During this state, we produce ketones, which are produced from the breakdown of fats in the liver. The end goal of a properly maintained keto diet is to force your body into this metabolic state. We don’t do this through starvation of calories, but through starvation of carbohydrates. Our bodies are extremely adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the main energy source. Cholesterol. A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. Weight Loss. As your body is burning fat as the main source of energy, you will essentially be using your fat stores as an energy source while in a fasting state. Blood Sugar. Many studies show the decrease of LDL cholesterol over time and have shown to eliminate ailments such as type 2 di Continue reading >>

Ketosis

Ketosis

Ketosis (Acetonemia, Ketonemia) is a common multifactorial disease resulting in downer cow syndrome in adult cattle worldwide[1]. Causes which predisposed to ketosis include: Ketosis is a common disease of dairy cows in early lactation caused by a negative energy balance that results in high concentrations of circulating nonesterified fatty acids (NEFAs) (acetone, acetoacetate, and β-hydroxybutyrate (BHB)). This disease is usually associated with fatty liver. Clinical signs Clinically affected cattle shows signs of anorexia, reduced milk yield and may present as downer cows. Neurological signs of restlessness and ataxia may sometimes be noted. A sweet breath may be observed by an observant farmer or veterinarian. Diagnosis is based on presenting clinical signs supported by laboratory tests such as urinalysis and milk detection of ketones. During the first month of lactation, ratios of glycerophosphocholine:phosphocholine less than 2.5 in the milk indicate a high risk for developing ketosis[2]. Blood tests showing elevated NEFAs can assist diagnosis in more valuable cattle[3]. Bolus IV administration of 500 mL of 50% dextrose solution is a common therapy[4]. Glucocorticoids including dexamethasone or isoflupredone acetate at 5–20 mg/dose, IM, generally results in a more sustained response. Oral propylene glycol (250–400 g) may be effective as ketosis therapy[5]. Continue reading >>

Ketosis

Ketosis

Ketosis is a metabolic disease that occurs when the cow is in severe state of negative energy balance. In this state, the cow mobilises large quantities of body fat but cannot convert this to energy through the usual pathways. Instead, ketone bodies are produced which in small amounts can be used by the cow for energy. However, when ketone production is high, the cow cannot use all the ketone bodies for energy and ketone levels increase in the blood. When this occurs the cow may suffer from ketosis. Types of Ketosis Type 1 ketosis is a result of a sudden drop in energy intake. This can be due to underfeeding or adverse weather events (e.g. snow storms) that prevent the cows from eating sufficient amounts of dry matter. Type 2 ketosis generally occurs post-calving, when the cow is mobilising excess body fat to meet the demands of milk production. Cows that are too fat at calving (BCS > 5) or cows that have been overfed pre-calving are particularly at risk. Silage ketosis is due to cows ingesting poor quality silage. The silage undergoes a secondary fermentation and when ingested will increase the risk of ketosis. Symptoms Ketosis can be displayed in two ways: Wasting form Lethargy (head down, lack of energy) Decreased dry matter intake Decreased milk production Often a sweet smell on the breath (acetone) Nervous form Excitable, uncoordinated and can become aggressive Strange behaviour such as eating soil, licking fence posts and gates, walking in circles, or standing with heads raised up and pushed into a corner etc. If a cow shows signs of ketosis seek advice from your veterinarian Prevention It is important to prevent ketosis from occurring, rather than treating cases as they appear. Prevention depends on adequate feeding and management of body condition score (BCS). E Continue reading >>

Ketotic Cows: Treatment And Prognosis (proceedings)

12Next An absolute requirement for treating ketosis in cattle is to identify and treat the primary cause for the negative energy balance. Symptomatic treatment for ketosis without attacking the primary cause is doomed to failure. Propylene glycol is a routine treatment for ketosis. Only 2 oral formulations are approved for use in cattle as a treatment and the dose rate is 8 oz, q 12 h, for up to 10 days (2 other formulations labeled for use as preventive treatment). Research suggests that 296 ml once/day as on oral drench is just as effective as 887 ml once/day. Propylene glycol is absorbed from the rumen as propylene glycol, some propylene glycol is metabolized to propionate in the rumen, but most is absorbed intact and metabolized to glucose in liver. Propylene glycol increases serum [glucose], decreases serum β-OH butyrate & NEFA concentrations but only if a functional liver as propylene glycol must be metabolized. Propylene glycol is only beneficial if rumen motility to aid mixing and absorption. Glycerol (same dose rate as propylene glycol) and sodium propionate (uncertain dose rate) also reported to be of use but are both considered inferior to propylene glycol. Sodium propionate may have palatability problems. Calcium propionate has been examined, but the evidence is not convincing that it is superior to propylene glycol, even though it also has calcium. Not very soluble, and large volumes need to be administered. 500 ml of 50% Dextrose IV is also a routine treatment (one time administration of 250 g). Numerous approved products for treating ketosis in cattle. A cow uses 50-70 g glucose/hour for maintenance and 200 g glucose/hour high production, from a total blood glucose pool <40 g. Milk is 4.5% lactose, 50 kg of milk contains 2.25 kg lactose (glucose and gala Continue reading >>

Negative Energy Balance

Negative Energy Balance

Starting at two weeks before calving, dairy cattle can already get in negative energy balance due to the growth of the calf, start of the colostrum production and a strong decrease in dry matter intake. Especially fat cows with a Body Condition Score of 4 or greater are at risk. Dairy cows in negative energy balance will start to mobilise body fat. Massive mobilisation of body fat reserves can result in metabolic problems, related to the fact that the liver can’t cope with the high amounts of fatty acids mobilised from the fat tissue. The consequences of a negative energy balance Dairy cows in negative energy balance have an increased risk to develop clinical or sub-clinical ketosis. Ketosis in dairy cows will have a negative impact on dry matter intake, health, fertility and production of the lactating cow. Recent evidence suggests that sub-clinical ketosis in cattle is much more common than clinical ketosis. Signs of ketosis in dairy cows Signs suggestive of sub-clinical ketosis in dairy cows are: A drop in body condition score of more than 1,0 point A disappointing milk production in combination with a fat:protein ratio above 1.5 A reduction of dry matter intake Reduced fertility Managing the negative energy balance correctly can therefore have a strong positive effect on farm profitability. Most of the problems occurring in the first few weeks after calving are related to dry cow management. Aim at a dry cow period of 8 weeks. During the first 6 weeks (far-off period) feed intake should be reduced to ensure the body condition score does not increase above 3.5. During the last two weeks (close-up period), the diet should be similar to what is fed after calving. Ensure energy density of the diet is high, this compensates partly for the lower dry matter intake immedi Continue reading >>

Ketosis

Ketosis

Idiots' Guide to The Biochemistry and Management of Ketosis Ketosis is a disease of dry cows that shows up in fresh cows. Fundamentally, we have a situation where the cow is mobilizing body fat (condition) faster than the liver is able to metabolize it. In order for the liver to normally metabolize that fat, glucose is required. If glucose availability is limited due to inadequate substrate (mostly propionate from the diet) or glucose production via gluconeogenesis is inadequate or impaired, then ketosis can result because of the inability to convert the fat to energy. Loss/mobilization of body fat is a normal part of the onset of lactation. As the rate of fat mobilization rises, circulating NEFA levels begin to rise. If these fatty acids reach the liver and begin to accumulate in significant amounts, the liver switches away from TCA towards ketogenesis in an attempt to provide more energy and eliminate the fat buildup. Ketogenesis produces the ketone bodies, acetoacetate and beta-hydroxybutyrate. Some ketone production is normal in all periparturient cows, so diagnosis is made on clinical history, physical examination, and the presence of significant ketones in milk or urine. Presence of ketones in milk or urine is inadequate, in and or itself, to make the diagnosis of clinical ketosis. Feed intake, or lack thereof, is a critical component in the onset of ketosis. In all cows, dry matter intake begins to decline approximately one month prior to calving, although many people will not notice this decline until several days prior to calving. as feed intake declines and galactopoeisis begins, body fats are mobilized, resulting in an increase in circulationg NEFA levels. NEFAs themselves are mild appetite suppressants, so they continue to hamper feed intake. NEFAs are also Continue reading >>

Ketosis Also known as: Acetonemia, Fat Cow Syndrome, Hypoglycemia and Pregnancy Toxemia. Primary ketosis, or acetonemia, is a metabolic disorder and is largely a disease that is influenced by management of dairy cows in early lactation. Ketosis is an important clinical and subclinical disease, as there are several metabolic disorders and diseases that commonly occur in the calving and the early lactation period that are linked to ketosis (including milk fever, retained foetal membranes and displaced abomasum). Hypoglycemia is the major factor involved in the onset and development of clinical ketosis. There is a gradual loss of body condition over several days or even weeks. There is also a moderate to marked decline in milk yield (up to 5 liters per day) over five to six days before the onset of obvious clinical signs (Edwards and Tozer, 2004). This can persist for up to two weeks after diagnosis (Rajala-Schultz et al., 1999). The disease is most commonly seen in high-yielding dairy cows in early lactation. Secondary ketosis due to lack of appetite as a result of another disease can be seen at any stage of lactation. Beef cows may also suffer from ketosis during pregnancy, although this is less commonly recognized. Primary ketosis in dairy cows To satisfy the requirements of milk production, the cow can draw on two sources of nutrients – feed intake and body reserves. During early lactation, the energy intake is insufficient to meet the energy output in milk and the animal is in a negative energy balance. In conventional farming, this is considered to be a normal metabolic situation in high-yielding dairy cows. Cows in early lactation are, therefore, in a vulnerable situation, and any stress that causes a reduction in feed intake may lead to the onset of clinical keto Continue reading >>

Eating Fat, Lifting Cows, And Preventing Seizures — An Intro To The Ketogenic Diet (with Dom D’agostino)

Eating Fat, Lifting Cows, and Preventing Seizures — An Intro to the Ketogenic Diet (with Dom D’Agostino) We’re about to dive into the world of ketosis with Dominic D’Agostino. But, to get there, we must first rewind the clock and start where Dom began. There’s a problem. We’re asked to solve it. Navy SEALs divers are getting uncontrollable seizures from oxygen toxicity during their dives. How can we prevent this? We scour the research. Eventually, we find an interesting study. Fasting is an effective treatment for seizures. In fact, it may be the MOST effective treatment for seizures. But fasting is only a short-term solution. We need something more sustainable. We read about the Ketogenic Diet. It mimics the effects of fasting without the undesired downside of starvation. Hmm… Enter The Ketogenic Diet Before us sits this Keto chest. In it lies the promise to prevent seizures. We walk to it, slowly reach for it’s handle, and pull open it’s top. We find more than we expected. Weird-sounding words. Articles with conflicting statements. Studies that only Harvard-graduated PhDs could understand. Most people would quit here. It’s just too much — too much jargon. Too much complicated science. Too much of an unfinished puzzle. There are other pressing matters to attend to. But we carry on. As we organize all the things that came flying out of the chest, we realize that our search for seizure prevention has opened a door to something with much broader implications. Something bigger even than cat pictures. We learn that the Ketogenic Diet is best known as an effective treatment for epilepsy, but early research shows data that supports further investigation in all these other areas as well: Cancer Alzheimer’s Parkinson’s Diabetes Brain Injury Metabolic S Continue reading >>

Ketosis

Ketosis

Not to be confused with Ketoacidosis. Ketosis is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy. Ketosis is a result of metabolizing fat to provide energy. Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose.[1][2] It is almost always generalized with hyperketonemia, that is, an elevated level of ketone bodies in the blood throughout the body. Ketone bodies are formed by ketogenesis when liver glycogen stores are depleted (or from metabolising medium-chain triglycerides[3]). The main ketone bodies used for energy are acetoacetate and β-hydroxybutyrate,[4] and the levels of ketone bodies are regulated mainly by insulin and glucagon.[5] Most cells in the body can use both glucose and ketone bodies for fuel, and during ketosis, free fatty acids and glucose synthesis (gluconeogenesis) fuel the remainder. Longer-term ketosis may result from fasting or staying on a low-carbohydrate diet (ketogenic diet), and deliberately induced ketosis serves as a medical intervention for various conditions, such as intractable epilepsy, and the various types of diabetes.[6] In glycolysis, higher levels of insulin promote storage of body fat and block release of fat from adipose tissues, while in ketosis, fat reserves are readily released and consumed.[5][7] For this reason, ketosis is sometimes referred to as the body's "fat burning" mode.[8] Ketosis and ketoacidosis are similar, but ketoacidosis is an acute life-threatening state requiring prompt medical intervention while ketosis can be physiological. However, there are situations (such as treatment-resistant Continue reading >>

Overview Of Ketosis In Cattle

Overview Of Ketosis In Cattle

(Acetonemia, Ketonemia) By Thomas H. Herdt, DVM, MS, DACVN, DACVIM, Professor, Department of Large Animal Clinical Sciences and Diagnostic Center for Population and Animal Health, Michigan State University Ketosis is a common disease of adult cattle. It typically occurs in dairy cows in early lactation and is most consistently characterized by partial anorexia and depression. Rarely, it occurs in cattle in late gestation, at which time it resembles pregnancy toxemia of ewes (see Pregnancy Toxemia in Ewes and Does). In addition to inappetence, signs of nervous dysfunction, including pica, abnormal licking, incoordination and abnormal gait, bellowing, and aggression, are occasionally seen. The condition is worldwide in distribution but is most common where dairy cows are bred and managed for high production. Etiology and Pathogenesis: The pathogenesis of bovine ketosis is incompletely understood, but it requires the combination of intense adipose mobilization and a high glucose demand. Both of these conditions are present in early lactation, at which time negative energy balance leads to adipose mobilization, and milk synthesis creates a high glucose demand. Adipose mobilization is accompanied by high blood serum concentrations of nonesterified fatty acids (NEFAs). During periods of intense gluconeogenesis, a large portion of serum NEFAs is directed to ketone body synthesis in the liver. Thus, the clinicopathologic characterization of ketosis includes high serum concentrations of NEFAs and ketone bodies and low concentrations of glucose. In contrast to many other species, cattle with hyperketonemia do not have concurrent acidemia. The serum ketone bodies are acetone, acetoacetate, and β-hydroxybutyrate (BHB). There is speculation that the pathogenesis of ketosis cases oc Continue reading >>

Cut Down On Ketosis

Cut Down On Ketosis

Ketosis is one of the most common metabolic diseases on dairy farms. It occurs when cows have an abnormal response to negative energy balance. After calving, all cows experience some degree of negative energy balance, mobilize body fat for the additional energy needed for milk production and lose weight during the first several months of lactation. But, if cows mobilize excessive amounts of fat, the metabolic process of converting this fat to energy can result in an undesirable buildup of ketones in the bloodstream. Clinical signs Watch for the following clinical signs: decreased milk production, poor appetite, decreased rumen fill, dehydration, sunken eyes and constipation. In severe cases, known as nervous ketosis, cows will exhibit neurologic signs such as weakness, running into walls, or compulsive licking/chewing. Cow-side diagnostic tests If you suspect ketosis, you have several options to help confirm the diagnosis. 1. Urine test strips. Once the cow urinates, hold the ketone strip into the urine and watch for a color change (purple) which often occurs within seconds. The urine strips are the least costly test; however, they do miss some cows with ketosis (due to lower sensitivity). 2. Milk Ketone Test strips. The milk test strips measure the amount of beta hydroxybutyrate (BHBA) in the milk which is the primary cow ketone. This test is more costly than the urine strip, but it is more sensitive than that test. Squirt milk into a clean container, dip in the strip for the manufacturer"s recommended amount of time, then compare the color change to the code on the bottle. 3. Precision Extra Blood BHBA meter. This is the most sensitive ketosis cow-side test. This meter is a human diabetic meter that measures ketones as well as glucose levels. Insert the strip into the Continue reading >>

Subclinical Ketosis On Dairy Cows In Transition Period In Farms With Contrasting Butyric Acid Contents In Silages

Subclinical Ketosis On Dairy Cows In Transition Period In Farms With Contrasting Butyric Acid Contents In Silages

Copyright © 2014 Fernando Vicente et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract This study examines the relationship between subclinical ketosis (SCK) in dairy cows and the butyric acid content of the silage used in their feeding. Twenty commercial farms were monitored over a period of 12 months. The feed at each farm and the silages used in its ration were sampled monthly for proximal analysis and for volatile fatty acid analysis. A total of 2857 urine samples were taken from 1112 cows to examine the ketonuria from about 30 days prepartum to 100 postpartum. Wide variation was recorded in the quality of silages used in the preparation of diets. Approximately 80% of the urine samples analyzed had no detectable ketone bodies, 16% returned values indicative of slight SCK, and the remainder, 4%, showed symptoms of ketosis. Most of the cases of hyperkenuria were associated with the butyric acid content of the silage used (; ). As the metabolizable energy content of the feed was similar, no relationship was observed between the proportion of cows with SCK and the energy content of the feed. In our study, the probability of dairy cows suffering SCK is higher when they are eating feed made from silage with a high butyric acid content (35.2 g/kg DM intake). 1. Introduction Subclinical ketosis (SCK) in dairy cows is a common metabolic disorder that can appear during the transition period, dry period, or calving, or in early lactation (Duffield et al. [1]), where the highest incidence of SCK occurs within the first 2 to 3 weeks of lactation [2]. The disorder is characterized by a high concentration Continue reading >>
