nutritional diseases in animals

Many published recipes have been only crudely balanced by computer, if at all, using nutrient averages. In EPI, supplementation with a powdered enzyme supplement, mixed with the food a few minutes before feeding, should be considered. It is typically measured in calories or joules. However, when calcium or phosphorus supplementation is excessive, insoluble and indigestible mineral complexes form within the intestine and may decrease magnesium absorption. Cats produce the enzyme hexakinase, which allows them to digest and use properly processed dietary carbohydrates. It is a … Nutritional disorders are a serious and often underrecognized consequence of many chronic diseases. Fatty acids that contain more than one double bond are called polyunsaturated fatty acids (PUFA). Anemia:. There is also no AAFCO dietary requirement for vitamin K for dogs and cats, because intestinal bacteria are able to synthesize it. Focal dysplasia of pancreatic acinar tissue and marked hypoplasia of seminiferous tubules, depletion of adrenal lipid, and focal atrophy of the skin have been reported. Assuming that an animal will eat a therapeutic diet when it gets hungry enough is inappropriate, and allowing an animal to starve in an attempt to stimulate its appetite is never recommended. Nutritional diseases of beef cattle, sheep and goats in Australia that can lead to significant economic loss include: The Merck Veterinary Manual was first published in 1955 as a service to the community. Although insulin sensitivity remains high in most diabetic dogs, no residual insulin production is left in the pancreas, and exogenous insulin therapy is required. In contrast, it is equally important not to unnecessarily restrict protein intake, because protein requirements are as high or higher in dogs with liver disease than in dogs without liver disease. In encephalopathic cats with hepatic lipidosis, dietary protein may need to be restricted but should not be severely so. Iron or copper deficiency (or both) is the major cause of hypochromic, microcytic anemia. ...

Therefore, when choosing omega-3 fatty acids to treat certain medical conditions, it is best to choose marine sources. Kittens or adult cats develop anorexia and muscular degeneration; depot fat becomes discolored by brown or orange ceroid pigments. Optimal diets for growing kittens and adult cats should contain a minimum 9% fat as dry matter (AAFCO guidelines), 4.7 g of fat per kg metabolic body wt/day for kittens, 4.7 g of fat per kg metabolic body wt/day for kittens, 2.2 g of fat per kg metabolic body wt/day for adult cats (NRC guidelines), or 22.5 g fat/1,000 kcal ME for growing kittens and adult cats (NRC guidelines). The National Animal Health Monitoring System reports that 7 per cent of beef cattle death losses in the southeast U.S. in 2005 were caused by digestive problems such as bloat and acidosis. They are also a source of essential fatty acids (EFA), which maintain functional integrity of cell membranes and are precursors of prostaglandins and leukotrienes. If the underlying cause of iron deficiency is related to hemorrhage, parasitism, consuming an unbalanced diet, or consuming too little of a complete and balanced diet, once the underlying cause is eliminated and the iron deficiency is corrected, longterm supplemental iron may not be necessary. The basic recipe should closely resemble “complete and balanced,” but single sources of protein can be sequentially tested and replaced. Your veterinarian can make a specific nutritional recommendation of a product proven to be effective in enhancing canineoral health. Some diabetic dogs have concurrent diseases, such as hyperadrenocorticism, and they may be very difficult to regulate if the hyperadrenocorticism remains untreated. Deficiencies of EFA induce one or several signs, such as a dry, scaly, lusterless coat; inactivity; or reproductive disorders such as anestrus, testicular underdevelopment, or lack of libido. The beneficial bacteria produce short-chain fatty acids and some nutrients (eg, some B vitamins and vitamin K). Unfortunately, food allergy cannot be differentiated from food intolerance, and skin testing for food allergies is unreliable. Puppies fed diets containing DHA perform better in learning experiments and are easier to train than puppies fed diets without DHA. Any recommendations for kcal requirements are only starting points and may need to be modified based on the response of the individual dog or cat. Recent studies suggest that α-linolenic acid (an omega-3 fatty acid) is also essential in dogs and possibly in cats. Consequently, general recommendations may need to be modified within this 30% range, and body condition scoring should be regularly performed. Fat-soluble vitamins (except for vitamin K in cats) are stored to an appreciable extent in the body, and when vitamins A and D are ingested in large amounts (10–100 times daily requirement) throughout a period of months, toxic reactions may be seen. Cachexia appears to be a response to increased catabolism with either normal or decreased appetite. Onions are more toxic than garlic. Type 2 DM has not been reported in dogs, although some dogs may develop diestrus-associated diabetes that results in insulin resistance secondary to progesterone production. Brain trauma, burns, and sepsis are all conditions with high metabolic demands, and the amount of energy needed varies among animals. 17.4.1 Scurvy. In dogs, the optimal calcium:phosphorus ratio should be ~1.2–1.4:1; however, minimum and maximum ratios by AAFCO are 1:1 to 2.1:1. Sarcopenia in Chronic Diseases. Supplemental water-soluble vitamins should also be used. Obesity is the excessive accumulation of adipose tissue—for dogs and cats, >20% above ideal body weight. A balanced amount of the necessary dietary minerals in relation to the energy density of the diet is important. Beneficial bacteria also function as immunomodulators and reduce liver toxins (eg, blood amine and ammonia). An individual who follows the diet or philosophy is known as a vegan.Distinctions may be made between several categories of veganism. As a result, NRC recommends vitamin K at 0.33 mg/1,000 kcal ME in puppies, at 0.45 mg/1,000 kcal ME in adult dogs, and at 0.25 mg/1,000 kcal ME in kittens and adult cats. Deficiency of zinc results in emesis, keratitis, achromotrichia, retarded growth, and emaciation. The condition can be confirmed by thyroid size (>12 mg/100 g body wt) and histopathology at necropsy. Any therapeutic renal diet should be phosphorus restricted, supplemented with omega-3 fatty acids (EPA/DHA) that come from fish oil, alkalinizing, supplemented with B vitamins, and in cats supplemented with potassium. In such cases, a highly digestible diet low in fiber (0–5%), moderate in fat (10%–15%) and protein (20%–25%), and containing carbohydrate from noncereal byproduct sources is recommended. The trial diet should be exclusively fed for the recommended length of time, and all treats, snacks, and table foods eliminated unless they are made of the exact same ingredients as the trial diet or contain a hydrolyzed protein source. About Antibiotic Use in Food Animals. The next step is to decide on a diet for the weight loss program. Regardless of whether the animal is polyuric, oliguric, or anuric, water should always be readily available. Head trauma significantly alters neurologic control of metabolic rate, which is usually increased. Clinical signs of magnesium deficiency in puppies are depression, lethargy, and muscle weakness. a Nutrient requirements are indicated on a dry-matter basis and are per kg of diet, not per kg of body weight of animal. Cats most commonly develop type 2 DM, although some cats may develop type 1, often secondary to chronic pancreatitis. If a cat does not like the weight loss diet chosen, then an alternative should be found. Adequate protein levels are important in any weight loss diet chosen. Minerals can be classified into three major categories: macrominerals (sodium, potassium, calcium, phosphorus, magnesium) required in gram amounts/day, trace minerals of known importance (iron, zinc, copper, iodine, fluorine, selenium, chromium) required in mg or mcg amounts/day, and other trace minerals important in laboratory animals but that have an unclear role in companion animal nutrition (cobalt, molybdenum, cadmium, arsenic, silicon, vanadium, nickel, lead, tin). a Nutrient requirements are indicated on a dry-matter basis and are per kg of diet, not per kg of body weight of animal. Some dogs and cats with nonseasonal pruritus are having an adverse reaction to food. A combination of decreased food intake and metabolic abnormalities can lead to nutrition-related disorders which in turn are associated with delayed recovery, as well as increased morbidity and … Destruction of thiamine has also resulted from treatment of food with sulfur dioxide or overheating during drying or canning, but deficiencies are now rare. Parvovirus enteritis is most common in puppies 6–24 wk old. Lipids can either be simple (triglycerides, wax) or complex (containing many other elements). An adverse reaction to a food is a clinically abnormal response to any type of food ingested. Currently, there is little evidence to suggest that certain specific nutrients in the diet, such as soy protein, lead to the development of gastric dilatation in susceptible dogs (see Gastric Dilation and Volvulus in Small Animals). Frequent feeding of small meals (4–6/day) lowers the amount of nutrients or metabolites that require hepatic processing at a single time, thereby imposing less metabolic demand on the liver. Most studies suggest that medium-chain fatty acids do not require initial transport in the lymphatics and instead can be absorbed from the intestines directly into the blood supply via the portal vein. Copper is an essential trace element for animals needed for body, bone and wool growth, pigmentation, healthy nerve fibres and white blood cell function. The first 2 wk of a puppy’s life is spent eating, seeking warmth, and sleeping. Most commercial dog and cat foods are fortified with vitamins to levels that exceed minimal requirements. EFA deficiencies are extremely rare in dogs and cats fed properly preserved complete and balanced diets formulated according to AAFCO profiles. NRC recommends levels of DHA and EPA in the diet of 0.13 g/1,000 kcal ME for puppies and 0.11 g/1,000 kcal ME for adult dogs. Raw food diets (see Raw Meat–based Diets) are also not recommended for dogs and cats. Proper nutritional support improves quality of life in animals with hepatic insufficiency prone to HE. Maintenance diets are generally not recommended for weight loss programs, because they are formulated to meet the nutritional needs of moderately active adults. Burns and other causes of significant areas of skin loss increase heat and water loss to the environment, thereby increasing energy needs. For example, unlike dogs, cats require dietary sources of vitamin A, arachidonic acid, and taurine. Formulating a homemade diet containing hydrolyzed protein is both very difficult and expensive. Onions and garlic contain thiosulfate, which can cause oxidative damage to RBCs and result in anemia. Sami Antoun, in Nutrition and Skeletal Muscle, 2019. 546 comments 761 shares 'Buy one, get one free' deals on fatty foods banned from April 2022 Dietary ingredients reintroduced may reproduce clinical signs as early as 12 hr after ingestion but can take as long as 10 days. The usual management of cachexia is to feed smaller amounts of a more calorically dense (ie, higher fat content), complete and balanced diet more frequently (3–6 meals/day). However, to slow the spread of antibiotic resistance, antibiotics should only be used when necessary. Dogs and cats 10%–20% above ideal body weight are considered overweight. The most common risk factors for DM in cats are obesity and increasing age. Niacin is found in most animal proteins but also in peanuts. There are conflicting studies regarding the fate of dietary medium-chain fatty acids. Feed may be inadequate due to overgrazing, drought, poor quality or digestibility or expense. B-complex is a combination of B vitamins. However, it does not measure a large portion of insoluble dietary fiber, nor any of the soluble dietary fiber. Before sharing sensitive information online, make sure you’re on a .gov or .mil site by inspecting your browser’s address (or “location”) bar. It is advisable to take a stepwise approach to reintroduction of calories, and multiple small meals are often tolerated better than large meals. As intake of a mineral exceeds the requirement, an excessive amount may be absorbed, or a large amount of the unabsorbed mineral may prevent intestinal absorption of other minerals in adequate amounts. In tumor cells, energy metabolism processes, including the pentose phosphate pathway and the malate aspartate shuttle, are accelerated remarkably (1), whereas, ATP production through glycolysis decreases greatly in the tissues of diabetic animals (2)… Food and water are usually withheld until vomiting ceases. Ten amino acids are essential in the diet of dogs: arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. This site complies with the HONcode standard for trustworthy health information: Conversely, fermentation also produces less desirable substances such as gases, ammonia, and phenols. Transient DM occurs in ~20% of diabetic cats, and these cats go into spontaneous remission usually within 1–4 mo after starting therapy for DM. Poor nutrition can lead to many serious disorders in dogs, including obesity, emaciation, rickets, increased allergies, and hair loss. Urate uroliths can occur in cases of liver disease, most commonly portosystemic shunts. Starvation is never a safe or humane way to cause weight loss. Some breeds of dogs with dilated cardiomyopathy may respond favorably to carnitine supplementation, which has also been beneficial in some breeds of dogs with CHF (including Boxers and Cocker Spaniels), in dogs with cystine or urate urolithiasis, and in dogs consuming a protein-restricted diet. Dietary management varies depending on the specific mineral composition of the urolith; however, regardless of composition, diluting the urine is important. verify here. Clinical signs can be subtle, from anorexia to more specific signs, such as hardened fat pads or ulceration on the tongue. The biologic value of a protein is related to the number and types of essential amino acids it contains and to its digestibility and metabolizability. Dietary fats also facilitate the absorption, storage, and transport of the fat-soluble vitamins (A, D, E, and K). Death in dogs is either related to chronic renal failure or acutely due to a massive aortic rupture. Learn nutritional diseases animal with free interactive flashcards. Raw meat products may contain pathogens. However, it is easier to change the diet when the animal is feeling reasonably well than when it is anorectic. Because fat can add considerably more calories to a finished diet, the amount of protein relative to energy must be balanced appropriately to the life stage and typical intakes expected for an animal’s size and needs. Nutritional Diseases of Fish By . Diseases From Cats and Dogs. Thiamine deficiency generally does not develop in cats fed properly prepared, commercial, complete, and balanced diets. General guidelines for dietary protein requirements in dogs and cats exist, but requirements vary depending on the digestibility of the protein in the diet. The causes of carbohydrate deficiency diseases Normally, when balanced diet is consumed, carbohydrate short fall does not arise. This is particularly important in cats, which often do not drink a lot of water. Animals with the same body weight can have 3-fold variation in daily kcal requirements, which are affected by age, neutering status, physiologic status (growth, gestation, lactation, etc), physical activity, environmental temperature, and any underlying abnormalities. Other nutritional diseases may result from harmful elements or compounds in the diet. Too little high biologic protein in the diet, relative to the energy density, can cause an apparent protein deficiency. Vitamin B12 is the only water-soluble vitamin stored in the liver, and dogs may have a 2- to 5-yr depot. A newer alternative diet commercially available for use in dogs and cats with suspected adverse reactions to food is a hydrolyzed protein diet. Egg has been given the highest biologic value, and organ and skeletal meats have a higher biologic value than plant-based proteins. In this case, daily maintenance fluid requirements in mL should equal the animal’s MER in kcal of ME. FOS are nondigestible oligosaccharides consisting of chains of fructose molecules. Nutrition has a large effect on the occurrence and severity of many diseases of dairy cattle. The generalized degeneration of the muscles in these animals, for which Dr. Goettsch and I suggested the term nutritional muscular dystrophy, was first observed by us in 1931 to develop following an ethereal-ferric-chloride–treated scorbutic diet supplemented by adequate amounts of orange or tomato juice.
