No nutritional adequacy statement is needed on treats and other food products that are not intended to be fed as the sole diet. The genetics was already determined at the moment of conception, we can’t do anything about the genetics at this point, so our treatment needs to address what we can control, and that is nutrition. “This product is intended for intermittent or supplemental feeding only” is on things like therapeutic diets, which are intended to be used short-term, under a veterinarian’s supervision. Fats produce energy by being broken down to acetyl CoA, which then enters the Krebs cycle (also called the citric acid cycle or tricarboxylic acid cycle [TCA]), where it is oxidized to produce CO2 and ATP. The first step is to get a diagnosis; this is done through history, clinical examination, observation of the typical laminitic gait, the presence of heat and inflammation in the feet, and possibly other systemic signs related to carbohydrate overload. Our goal is to catch these prior to getting a serious problem, and with simple nutritional adjustments try to reverse the changes. In future in veterinary animal nutrition the last mentioned aspects will become greater importance in lecturing and research. If the cells are starved for energy, the amine group is removed and excreted and the rest of the molecule is broken down for energy. Veterinary and Animal Science programs specifically hope that graduates will ultimately demonstrate the competency as traditional students when working with a broad range of species in a constantly changing landscape. The importance of nutrition to health has been recognised for more than 2,000 years, since the ... Studies have shown veterinary surgeons do not feel they receive adequate training in small animal nutrition during veterinary school. Fats are considered energy-dense nutrients. The final point I would like to make about nutrition is that for animals to survive and thrive, nutrition does not need to be perfect. The name tells you what likely percentage of a product is present. Byproducts (protein sources from parts of the animal not used for human food), Meat and bone meal (cannot feed from ruminants because of concerns about bovine spongiform encephalopathy (BSE = mad cow disease)), Blood meal (dried blood, great protein supplement), Feather meal (ground feathers, less digestible protein supplement), Milk and milk products (casein, whey, etc. “Least cost” diet formulations – This is performed after a ration is formulated as a way of trying to optimize some particular aspect, for example, cost, while meeting the nutrient requirements and pre-set constraints. Vitamin C can be synthesized in many species. Developmental Orthopedic Disease (DOD) is commonly seen in young fast growing horses between 3-4 months up to near 2 years old. and feed = what may be mixed to produce animal food and/or what is fed to farm animals (cows, horses, chickens, sheep, etc.). Would I really feed this ration to the animal being considered? December 2017 It is made for convenience and long shelf life. The proper name is “physitis” as the pathology is actually in the growth plate, the physis, and not the epiphysis, which is the segment of bone between the bone end and the growth plate. Feed is the largest input cost in animal production and what feed is provided varies with age, breed, production and gain needs, and pregnancy status of the animals, and season of the year, such that a given client may be responsible for a wide variety of different feeding regimens for the animals under their care. However, over my practice career I have become convinced that it is a huge issue affecting the long term quality of life as well as longevity. Be careful about trusting the computer (Is the program up to date? What is percentage protein on a dry matter basis? Dog/cat nutrient profile for…” followed by which life stage is represented (maintenance, gestation, lactation, growth, all life stages). Vaccines and Vaccinations: Production Animals, 14. The goal is to make sure all three of these are the same for all animals intended to eat that diet. and service solutions. Work from an existing ration. November 2020 In fact I consider some degree of DOD to be normal in most young growing horses, and most survive it just fine. The skin barrier cocktail The Waltham Centre for Pet Nutrition screened 27 substances that were thought to provide a … Microminerals often are associated with a specific enzyme, hormone, carrier protein, or vitamin, and include iron, copper, manganese, zinc, selenium, cobalt, and iodine. September 2017 Diseased animals in that group (for example, those carrying parasites) also may require more nutrients. Protein broken down in the rumen is available to microbes for synthesis of high-quality proteins and the remainder passes into the small intestine. Overweight horses like overweight people put more stress on their joints, and are much more susceptible to lameness problems especially as they get older. Pet food industry in the United States – About 87% of dog and about 95% of cat owners in the United States feed at least 75% of their animal’s diet as commercial pet food. If they do not, they become obese. Energy metabolism and imbalances in metabolic processes can induce various diseases in animals. In monogastric animals, there is limited digestion of carbohydrates in the mouth and stomach. When in doubt, look at the animals! Nitrogen extraction is used as an estimate of crude protein – about 16% of protein is nitrogen. Formulation is only one step and is not the end point. Balanced = feed to meet the pet’s energy requirement and requirements for non-energy nutrients will automatically be met. animal agriculture. Feed analysis is best used for directly measurable components (fiber, macronutrients, protein) and is poor for constituents with wide variation or error in measurement (microminerals). This is a unique identifier of a batch of pet food and is valuable in face of a recall or other concern. Feeding trials are a superior way to determine nutritional adequacy. Protein digestion is intertwined with energy use. Vitamin A is also called retinol acetate and supports vision, cell differentiation, and reproduction and growth. Types of feed include dry forages (grass or legume hay), straw (plant parts remaining after grains are harvested), corn stover (parts of corn remaining after corn is harvested); wet forages such as green chop (undried grass and legume hays), and silage and haylage; byproducts = commodities; grains; protein concentrates; and lipid sources. Nutrition Services Offered Weight loss management. You must also consider whether or not you will sell pet foods at your clinic and if so, how you will decide which you promote. January 2017 Veterinary medicine and animal sciences deal with the study of the animals, the diseases & disorders that occur in various animals and treating them successfully. We now know that many of these horses have a genetic predisposition for this, and we have learned how to identify these horses through genetic testing, which until recently wasn’t an option. Proper nutrition is paramount to good health. There is no hard definition that distinguishes “food” from “feed” but in general, food = what is actually eaten, mostly by people and non-farm animals (dogs, gerbils, birds, lizards, etc.) Type, form, nutrient content, quality, cost, Mix, order of mix, processing, feed delivery (amounts, timing delivery system), monitoring delivery and consumption. Milder cases may recover completely, or have varying degrees of chronic lameness depending on the amount of damage. Vaccines and Vaccinations: Individual Animals, 4. Thus, contrary to Dr. Alinovi’s assertions, we simply do not discourage the practice of veterinary nutrition by non-diplomates. The veterinarian provides nutrition counseling for healthy pets, for disease prevention, and for use of therapeutic diets. This is a place we can go to get an insight into their thoughts. A food is 12% moisture and 17% protein. Percentage protein on a dry matter basis is 17 divided by 88 = 19.3%. All results must be normal for the food to “pass”. We used to think that obesity in horses was not a significant health issue. I think that most of these horses have a combination of factors involved. Digestibility and types of protein present play a role. Ingredient versus nutrient – Nutrient = substance that must be consumed in the diet to provide a source of energy, substrate for growth or substance to regulate growth, metabolism, and energy production. In the small intestine, pancreatic enzymes (trypsin, chymotrypsin) break polypeptides down further into small peptides and amino acids. Rather, we view it as a critical component of the practice of veterinary medicine and see the appropriate application of veterinary nutrition precepts by general practitioners to be of important benefit to their patients. Laminitis or founder is a multi factorial disease, but regardless of the inciting cause it is much more difficult to manage in overweight animals due to the increased pressures involved because of the excess weight. Carbohydrates undergo microbial fermentation to form volatile fatty acids; this is described in detail later in  these notes. When ingested, fats remain separate from fluid components in the stomach until they are emulsified. These include, not in order of importance: animal welfare, clinical communication skills, career opportunities within veterinary medicine, history of the profession, legislation, personal finance, personal skills, practice management, professional behavior, a reflective approach to personal and professional development, thinking skills and a variety of other veterinary issues. scholarship will be awarded to a full-time, third-year production livestock Doctor of Veterinary Medicine in the United States, Mexico or Canada. The first sign of laminitis is usually reluctance to move. Results depend on accuracy of the definition of constraints and of nutrient content, and on the prices of feed used. Furthermore the nutritionists have to look for parameters to control a species specific correct nutrition especially in food producing animals. This type of bone disease is known as “physitis”; commonly called “epiphysitis”. In horses the disease results from carbohydrates being fed at a rate that allows them to pass into the fermentation vat (large colon and cecum). Feed quality is dependent on the right feed component being used (be cautious of similar names), feed being collected at the proper stage of maturity and properly stored and processed, the bioavailability of the nutrients, and freedom from contamination, toxins, and micro-organisms. Improper nutrition is an unnecessary cost of ownership / management of animals. They typically are balanced for minimum needs and are adjusted for specific conditions. The general recommendation is to start at the low end of the recommended amount listed on the bag and to monitor body condition to ensure the animal is not being underfed or overfed. It is valuable to think about energy needs when feeding protein because if the body cannot use the protein, it will be excreted or “wasted”. ), Seeds (shell corn, wheat, oats, soybeans), Residues or byproducts (beet pulp = leftovers from sugar beet production, citrus pulp = leftovers from orange juice production, sweet corn stover, potato waste = leftovers from making French fries, almond hulls, cottonseed, distillers grains = leftovers from the bottom of the beer vat, brewers grains, straw), Extracted portion = soybean meal, corn starch, molasses, corn oil. These are ground and processed rock and have variable bioavailability. Cats handle carbohydrates uniquely; this is described in detail later in these notes. Understand the approach and nutrition first, then use the tool. The Role of Nutrition in Large Animal Veterinary Practice Some practitioners may choose not to include nutrition in the services they offer as a veterinarian. May 2016 It was typically seen in heavy muscled horses that were on a high plane of nutrition, and the treatment at the time was anti inflammatory medication, muscle relaxants, rest, fluid therapy, and decreasing the grain and concentrates in the ration. – Quality of food produced (wholesome, nutritious) – Environmental impact (for example, are we overfeeding something that will end up in the manure), To provide nutrition to support health and prevent disease. Comparison of products requires evaluation on a dry matter basis (DMB). An example of a time when this information is valuable clinically is when weight loss is desired; an animal on an energy-restricted diet should get a generous amount of high-quality protein to help maintain lean body mass and ensure an appropriate intake of nitrogen intake to balance nitrogen use (= nitrogen balance). The next question is why are these horses growing this fast? ); enzymes, albumin, hormones, and other nitrogen-containing compounds; and are broken apart to provide energy. ...but I can make dietary recommendations on obese horses, and it is up to the owner to either take or reject my advice. In an extreme case the hoof will actually fall off. Although this is a very complex disease with a myriad of causes, nutrition has a huge role in its cause and in its treatment. Nutrients are chemical substances obtained from food and are used to provide energy, to build structure (bone, muscle, etc. The field of veterinary behavioural medicine occupies itself with the diagnosis, treatment and prevention of behaviour disorders in animals. Dietary Protein Recommendations % Dry Matter Basis, Dietary Fat Recommendations % Dry Matter Basis. Production – Growth – Body condition – Health – Fecal consistency – Behavior – Family living/economic outcomes – Family lifestyle; how hard is it to feed this diet? THE IMPORTANCE OF VETERINARY MEDICINE TO LIVESTOCK HEALTH By Dr. Godfrey A. Springer, B.Sc, DVM Whether it is a herd of cattle, a flock of sheep or goats, a pen of chickens or a group of weaned pigs, poor animal health decreases the performance of the animals leading to lower production and financial losses. When a horse has an acute case, it generally requires aggressive veterinary treatment with the aforementioned therapies to have a successful recovery. Concerns include digestibility, physical form, palatability, association with other nutrients (for example, nitrogen-containing nutrients to help break down carbohydrates). Nutrition may be a limiting factor in production or performance. Assuming you agree, consider that processed food has become today’s staple diet for animals. When swelling occurs inside something that can’t accommodate swelling, you get increased pressure. It turns out that the myoglobin is toxic to the kidney, so in a severe case this can cause kidney failure. Other nutritional resources with whom we may work include owners / farmers, feed company personnel, independent nutritionists, feed product companies, extension personnel, university experts, and agronomy experts who study crops and their nutrient content. Fats in the diet efficiently provide energy, transport and store fat-soluble vitamins, increase palatability and satiety, and reduce dustiness of feed. Energy density can be increased by using fats in the diet. Mild cases of OCD can heal with conservative treatment, but many require surgery to clean up the affected cartilage and underlying bone. A new trend is unique game meats – for example, buffalo – 100% buffalo = buffalo meat with water sufficient for processing – This is not a complete and balanced diet and the label will reflect that. Nutritional management consists of providing a diet that provides them with all of their basic nutritional requirements while minimizing the amount of soluble carbohydrates. 11/6/2016 Comments . We are fortunate to have that level of experience in our doctors and staff. This causes large scale death of the bacteria, resulting in decomposition of the bacterial cell wall, and the release of a product known as endotoxin; a component of the bacterial cell wall. Some practitioners may choose not to include nutrition in the services they offer as a veterinarian. Large lipids combine with bile to form micelles that are water-soluble and move directly into cells. A variety of extraction processes can be used. This commonly is used in food animal formulation. It is important for practicing veterinarians to have a working knowledge of nutrition to be able to adequately diagnose and treat many of the common ailments that we see. There is little storage of excess amino acids. The important thing is recognizing when it is getting out of hand, and taking steps to treat it before it causes permanent damage. It is valuable for us to know how to read the labels so we can educate clients. Animal behaviour problems are a major welfare concern as they are one of the primary reasons animals are relinquished and veterinarians are requested to euthanise animals. The key value is added by monitoring the implementation and the results of the feeding program. Without getting over technical, this is a disease that is generally caused by ingesting a high carbohydrate meal. My recommendation is to reduce the quantity of feed (I usually start out recommending they feed half of what they are presently feeding) of a mediocre quality grass hay, and balance that with an appropriate protein, vitamin, and mineral supplement. About 1/3 of consumers in one study understood how nutritional adequacy was determined in pet foods and 2/3 did not. Ingredient = the means to achieve nutritional and palatability goals – an ingredient may supply one nutrient, many nutrients, or none. Grazing animals also get fresh forage on pasture. The soft tissues of the foot are encased in a rigid structure known as the hoof capsule that is a perfectly fitting but tight boot. Vitamin K is also called menadione. Absorbed small peptides and amino acids are reassembled into new proteins in the liver and other tissues. When I attended veterinary school in the 1970’s it had several names, Monday Morning Disease, Azotemia, Myoglobinuria, Tying Up Syndrome, among others. The sugars and carbohydrates are supposed to be broken down and absorbed out of the stomach and small intestine prior to entering the large colon; large amounts of sugars in the large intestine results in the organisms living there having a massive overgrowth. Most of the bile released into the small intestine is reabsorbed and sent back to the liver (= enterohepatic circulation of bile). Fiber is not digestible in small animals but serves other purposes such as preventing constipation and normalizing intestinal motility. Essential amino acids are those that must be in the diet; these vary by species. Acid and detergent extractions are done to define the two forms of fiber, which are hemicellulose (neutral detergent fiber) and cellulose and lignin (acid detergent fiber). All are reported on an “as fed basis”. Nutrition is the foundation of optimal health. Doing the arithmetic. They have reliably measured levels in feeds but levels present do not guarantee digestive availability. Our livestock have an amazing ability to do well on a wide variety of feed products, and even do well in the face of deficiencies of some nutrients and an excess of others. Ammonia and carbon dioxide combine to form urea, which is excreted. The label information panel must contain the following things: nutritional statement (adequacy claim), basis of nutrition claim, ingredient list, guaranteed analysis, manufacturer or distributor name and address, feeding directions, and universal product code. 2. You should always take a diet history which should include, at a minimum, what type of food(s) they’re getting, how much they’re being fed, and how often they’re being fed. For those of you interested, a detailed paper is available on the AAEP Website at the following address: The following is a copy of the summary of the paper By Stephanie Valberg, DVM, PhD, Associate Professor, University of Minnesota, College of Veterinary Medicine, is a catch all phrase for a number of bone related diseases commonly seen in young growing horses. The food is provided for a minimum time of 26 weeks, with a physical examination at beginning and end, body weight weekly, and labwork at the beginning, middle and end of the trial. This can be compensated for by adjusting animal comfort, access to feed (time, conditions, competition), physical forms of feeds, water content, palatability, and balance of feeds to enhance digestion. These include sugars, starches, pectin, hemicellulose, cellulose, and lignin. This includes total food intake (usually best expressed on a dry matter basis [DMB]), energy (calories, essential fatty acids), protein (total and essential amino acids), fiber, macro- and microminerals, vitamins, and water. Animals lived on whatever forages were available in nature for millions of years before we domesticated them, and the genetics that enabled them to survive then still are with them today. ; 2 Unit of Veterinary Public Health and Epidemiology, Department for Farm Animals and Veterinary Public Health, University of Veterinary Medicine, Vienna, Austria. There are fewer than 100 pet food manufacturers and are about 5000 different pet food labels in the US. Excess minerals and nutrients will be excreted, and deficient nutrients will be conserved to allow animals to survive and thrive even on sub optimal feeds, as long as the ration has adequate energy content. These are responsible for the structure of the bones and teeth, maintaining an action potential across cell membranes, fluid balance, acid-base balance, storage and transport of energy, and for acting as second messengers and co-factors. Manufacturer or Distributor Name and Address. The overgrowth of gram negative bacteria in either the rumen of ruminant animals or the large colon of horses results in an increase of bacterial byproducts and an increased acidity. Nutritional statement by the formulation method is either calculated from known composition of ingredients in the diet or is determined by laboratory analysis of the food. Veterinarians specializing in behavioral medicine perform detailed evaluations to determine if there’s a medical reason for animal conduct issues and help develop treatment plans. Types of analysis include wet chemistry and near infrared analysis. I think there are two answers to this question, genetics and nutrition. Some bile moves through the GI tract and is excreted in feces. Bone in young animals increases in length at the growth plates; there is a thin plate of cartilage at the end of the long bone that is actively laying down new bone. Vitamin E is also called tocopherol. Corn is lysine deficient so soybeans may be added in rations to provide lysine. Nutrition in a diet may be determined either by the formulation method or by a feeding trial. When I see a grossly obese horse, I explain to the owner the risks associated with obesity, and often refer them a feed store to provide products to deal with it. Energy metabolism is the process of ATP production. Complete = all nutrients present and bioavailable. Subtracting these from total carbohydrates yields the non-fiber carbohydrates, which are sugars, starches, and pectins. You should expect yourself to be able to physically examine pet food, calculate food dosage, and interpret pet food labels. Computers do a lot of it. The new bone is relatively soft, and is subject to damage from compressive forces during weight bearing, especially when young horses are engaged in vigorous exercise. Pet foods and pet food labeling are regulated by the American Association of Feed Control Officials (AAFCO). There is an optimal amount of intake of any given nutrient; if too little it taken in, the animal is deficient and if too much is taken in, toxicity may occur. February 2018 Breakdown of carbohydrates is mediated by pancreatic alpha-amylase and brush border enzymes in the small intestine and by fermentation of undigested and unabsorbed carbohydrates in the large intestine. For me as a veterinarian that generally involves my recommending the owner use a commercial feed that is already balanced. Energy and non-fiber carbohydrates can be assessed by calculation. The first thing is to make sure the ration is as low in energy as the colt can stand, while still being reasonably balanced with the proper minerals and high quality protein. Every single diet can be described as three diets – the one that is formulated on paper, the one that is delivered, and the one the animals eat. Some are non-structural carbohydrates, such as sugars and starches. ), and to regulate growth, maintenance, and repair. This is of special importance in young show animals; by pushing them early we are putting them at increased risk of developmental orthopedic disease; this is true of all species, but particularly in horses because they are expected to be athletes. Many of these horses are susceptible to recurring attacks of laminitis even if they recover completely. is another fairly common disease seen that has a nutritional component in treatment and prevention. When they do walk, they have a stilted gait. An owner will often see this bony swelling and possibly also notice that the foal or yearling appears sore or lame. “Bypass protein” in ruminants is dietary protein that, either by some means of alteration or because of the type of protein, is not broken down by microbes in the rumen. It has been associated with many diseases such as diabetes and joint disease and has been shown to shorten the lifespan of dogs. The ingredient list must show each ingredient, listed in descending order by weight and listed on “as is basis” (as it comes out of the bag or can). You can find much information about nutrients in tables. However, we can make an animal grow faster sooner by increasing the energy in the ration. Dry matter = 100-12 = 88. It is an anti-oxidant. Backyard Poultry / Caged Birds / Fish / Reptiles / Amphibians, Appendix - Common disorders of non-traditional pet species. Add minerals and vitamins to meet needs. Nutritional management becomes an important part of their care for the rest of their life. Animal nutrition focuses on the dietary nutrients needs of animals, primarily those in agriculture and food production, but also in zoos, aquariums, and wildlife management. To integrate the basic knowledge of nutrition with practical animal feeding, the monograph continues with a discussion on nutritional requirements of animals for maintenance and production (Chapter 11), as well as the regulation of food intake by animals As a rule of thumb, canned foods are 75% water and dry foods are about 10% water. Liz practices as a relief veterinary technician and consultant in the San Francisco Bay Area for both general and emergency/specialty practices. The terms “fat” and “triglyceride” are synonymous, as fats are made up of three fatty acid chains and glycerol. american Academy of Veterinary Nutrition (AAVN) The American Academy of Veterinary Nutrition (AAVN) is an international association of veterinarians, animal nutrition scientists, veterinary technicians, industry representatives, and students (veterinary medicine, veterinary technician and animal science) with a common interest in animal nutrition. Feed intake is the limiting constraint to meeting nutrient needs in some animals because they cannot physically take in enough of a given ration to get all the nutrients available in that ration. Vaccines and Vaccinations: Introduction, 3. Start by including some of the largest components (fiber in ruminants, protein in monogastrics). One, $3,000 . Water-soluble vitamins are not stored and toxicity is rare. Examples of circumstances where protein wasting occurs include lack of energy from other sources so the amino acids are used for energy only, if the diet supplies more protein than the body needs, if a single amino acid is provided in excess, or when the diet supplies low quality protein with too few essential amino acids. The endotoxin causes many adverse events; primarily it increases the permeability of the cell walls of the capillaries in the hoof. The breakdown in the rumen is vital; microbes in the rumen contribute up to 70% of the protein available for absorption in the small intestine.
