nutrition related diseases in animals

Cats have a dietary requirement for an additional amino acid, taurine. These AAFCO nutrient profiles for dog foods presume an energy density of 3.5 kcal ME/g dry matter. Studies have demonstrated remarkable genetic diversity among humans. Maggot Video: The Truth Behind the Maggots Inside the Cats Paws. If antioxidant protection from a natural preservative system (eg, vitamin C or mixed tocopherols) or from synthetic preservatives (eg, BHA, BHT, ethoxyquin) in the diet is insufficient, dietary and body polyunsaturated fats become oxidized and lead to steatitis. Even so, an animal that tends to develop allergies can develop allergies to the new ingredients, too. The higher the biologic value of a protein, the less protein is needed in the diet to supply the essential amino acid requirements. Most commercial adult dog foods typically contain 5%–15% fat (dry-matter basis). poverty (infant death, communicable disease, nutrition deficiency), the doubling of life expectancy from 35 years before 1949 to 73 years (male 70, female74) in 2005(2) and the major causes of disease and death in Mainland China have shifted from predominantly infectious disease and diet-related deficiency diseases to obesity and other Rickets has been reported in kittens fed diets deficient in vitamin D, even though dietary amounts of calcium and phosphorus were normal. The more double bonds a fatty acid contains, the more prone it is to rancidity if not properly preserved. Obesity, diabetes and even cancer can be traced back to a poor diet, so it's important to learn proper nutrition. The six classes of nutrients are water, protein, fat, carbohydrates, vitamins, and minerals. General guidelines for dietary protein requirements in dogs and cats exist, but requirements vary depending on the digestibility of the protein in the diet. Nutrition plays an important role in preventing illness and reducing morbidity and mortality in people living with HIV, tuberculosis, malaria, and other infectious diseases. These diets were formulated to address the increasing intolerance to commercial foods that pets have developed. This deficiency was due to inadequate amounts of taurine in cat food formulas, which in turn had occurred due to decreased amounts of animal proteins and increased reliance on carbohydrates. The growth rate begins to plateau after 6 mo, and growth may be completed by 8–12 mo of age in small and medium breeds and by 10–16 mo in large and giant breeds. There are conflicting studies regarding the fate of dietary medium-chain fatty acids. If pet owners wish to feed their pets homemade diets, the diets should be prepared and cooked using recipes formulated by a veterinary nutritionist. This site complies with the HONcode standard for trustworthy health information: In cats, carbohydrates apparently are not essential in the diet when ample protein and fats supply glucogenic amino acids and glycerol. In addition, the longer chain omega-3 fatty acid, docosahexaenoic acid (DHA), may be conditionally essential for normal neurologic growth and development of puppies and kittens. There is also no AAFCO dietary requirement for vitamin K for dogs and cats, because intestinal bacteria are able to synthesize it. Employment, Economic Development and Innovation. A primary function of dietary protein is as a source of essential amino acids and nitrogen for the synthesis of nonessential amino acids. If an animal is consuming a diet containing predominantly plant protein sources, protein requirements may be higher than if the animal is consuming a diet containing predominantly animal protein sources. Puppy diets usually contain 8%–20% fat (dry-matter basis). Clinical signs of magnesium deficiency in puppies are depression, lethargy, and muscle weakness. However, it does not measure a large portion of insoluble dietary fiber, nor any of the soluble dietary fiber. Enterotoxemia in Sheep This feed-related malady causes almost sudden death in sheep due to a toxin produced by Clostridium perfringens type D and sometimes type C. Indiscriminate mineral supplementation should be avoided because of the likelihood of causing a mineral imbalance. Production of less desirable fermentation products can be minimized by using a moderately fermentable fiber source; examples include beet pulp, inulin, and psyllium. In their first few hours of life, neonates must suckle good quality colostrum from the dam to obtain maternal antibodies (immunoglobulins). The four carbohydrate groups functionally are absorbable (eg, monosaccharides such as glucose, galactose, and fructose), digestible (eg, disaccharides, some oligosaccharides), fermentable (eg, lactose, some oligosaccharides), and poorly fermentable (eg, fibers such as cellulose, which is an insoluble fiber). Normal birth weight of pups depends on breed type (120–550 g). PUFA are designated as either omega-3, omega-6, or omega-9 fatty acids, depending on the location of the first double bond. Sorry, your blog cannot share posts by email. Destruction of thiamine has also resulted from treatment of food with sulfur dioxide or overheating during drying or canning, but deficiencies are now rare. Different carbohydrate sources have varying physiologic effects. Rations >4.5 kcal/g should be corrected for energy density. The moisture content of canned pet foods varies from 60% to >87%. If inadequate amounts of dietary carbohydrates are available, the body will synthesize glucose from glucogenic amino acids and glycerol. Fermentation of fiber produces the short-chain fatty acids acetate, propionate, and butyrate. However, unacclimatized adult cats increased their daily caloric intakes nearly 2-fold when environmental temperatures of 23°C and 0°C were studied. These disorders are frequently caused by either the amount or quality of the food that is offered but can also be triggered by some medical disorders and infestations of … EFA deficiencies are extremely rare in dogs and cats fed properly preserved complete and balanced diets formulated according to AAFCO profiles. The caloric content of pets foods is usually expressed in kilocalories (kcal), which is 1,000 calories. Dogs and cats require specific dietary nutrient concentrations based on their life stage. Plugs, crystals, and stones are more common in cats eating dry diets, due to the chronic dehydration and highly concentrated urine they cause. Although the classification of fiber based on its solubility is still used, fiber is better classified based on its rate of fermentability. Water-soluble vitamins are usually readily excreted if excess amounts are consumed and are thought to be far less likely to cause toxicity or adverse effects when ingested in megadoses. Hyperthyroidism. Dry cat food is now considered the cause of feline diabetes; prevention and treatment include switching to a high protein, high moisture, low-carb diet. In cats, there is evidence that magnesium concentrations >0.3% (dry-matter basis) may be detrimental if the diet is too alkaline. Technical note 14. Saturated fatty acids are used primarily for energy in the body, whereas unsaturated fatty acids are found in cell membranes and blood lipoproteins. Other nonessential amino acids may become conditionally essential when an animal has an underlying disorder that either interferes with synthesis of the amino acid or results in its excessive consumption or loss. In what is known as the "nutritional transition", traditional plant-based diets including foods such as cereals and potatoes are increasingly being replaced by diets that are richer in added sugars and animal fats.This transition, combined with a general trend towards a more sedentary lifestyle, is an underlying factor in the risk of developing chronic diseases. Certain cells, such as brain cells, require the simple carbohydrate glucose as fuel. Dry pet foods contain 3%–11% water, and semimoist foods contain 25%–35% water. Excessive magnesium is excreted in the urine. Dietary fats also facilitate the absorption, storage, and transport of the fat-soluble vitamins (A, D, E, and K). Dental disease. In cats, steatitis results from a diet high in PUFA, particularly from marine fish oils when these are not protected with added antioxidants. Low blood concentrations of BCAA can occur in liver disease, but it is very unclear whether supplementation is justifiable given their high cost and the lack of conclusive evidence that they are beneficial. Do Cats Replace Their Teeth Like Humans?هل القطط تبدل الأسنان مثل البشر. Certain of these alterations also result from the retinal degeneration that is seen in taurine deprivation. Amino acids supply both nitrogen for the synthesis of all other nitrogenous compounds and energy when catabolized. Enter your email address to follow this blog and receive notifications of new posts by email. Thiaminase, which tends to be high in uncooked freshwater fish, can produce a deficiency by rapid destruction of dietary thiamine. Owner neglect is also a frequent contributing factor in malnutrition. There is no AAFCO dietary requirement for vitamin C for dogs and cats, because they are able to synthesize it in the liver. The beneficial bacteria produce short-chain fatty acids and some nutrients (eg, some B vitamins and vitamin K). Post was not sent - check your email addresses! ( Log Out /  Protein restriction is NOT recommended in many cases for animals with liver disease based on evidence from research in humans. Protein suitable for cats must supply >500 mg of taurine/kg diet dry matter. Nonetheless, cats fed diets deficient in vitamin A exhibited conjunctivitis, xerosis with keratitis and corneal vascularization, retinal degeneration, photophobia, and slowed pupillary response to light. Breed differences also affect caloric needs independent of body size, eg, Newfoundlands appear to require fewer calories/day than Great Danes. In this case, daily maintenance fluid requirements in mL should equal the animal’s MER in kcal of ME. Only protein, fat, and carbohydrate provide energy; vitamins, minerals, and water do not. Crude fiber, which is what is listed on pet food labels, quantifies insoluble dietary fiber, which is primarily cellulose, some lignin, and a small amount of hemicellulose. Eicosapentaenoic acid (EPA) is another longer chain omega-3 fatty acid that has been shown to be beneficial in the diet for treatment of certain skin, renal, and GI conditions, as well as cancer, arthritis, and hyperlipidemia. Signs produced by protein deficiency or an improper protein:calorie ratio may include any or all of the following: reduced growth rates in puppies and kittens, anemia, weight loss, skeletal muscle atrophy, dull unkempt hair coat, anorexia, reproductive problems, persistent unresponsive parasitism or low-grade microbial infection, impaired protection via vaccination, rapid weight loss after injury or during disease, and failure to respond properly to treatment of injury or disease. Often, there is a history of feeding a diet composed almost entirely of meat, liver, fish, or poultry. Macadamia nuts are also potentially toxic to dogs and cats and can cause weakness, depression, vomiting, ataxia, muscle tremors, hyperthermia, and tachycardia. Optimal diets for growing kittens should contain at least 24%–28% ME as protein or 30% protein as dry matter (AAFCO guidelines) or 45 g protein/1,000 kcal ME (NRC guidelines). Unless synthetic essential amino acids are added, some animal protein is necessary in the diet to prevent taurine depletion and development of feline central retinal degeneration or dilated cardiomyopathy. ANIMAL NUTRITION • ENERGY-RELATED DISORDERS: 1)- Fatty Liver Syndrome: (Accumulation of fat within the cow’s liver.) Dietary fermentable fiber also functions as a prebiotic in dogs and cats. Some experts theorize that excess iodine in commercial cat food is a factor. Optimal diets for adult cats should contain ~20% ME as protein or 26% protein as dry matter (AAFCO guidelines or 40 g protein/1,000 kcal ME (NRC guidelines). 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).
