Providing pets with vitamins, minerals, and other nutritional components is important to pet health and well-being, and the best way to do this is to feed a high-quality, complete, and balanced diet. Supplementing dog food often upsets the balance and might cause health problems.
People supplement their dog's diet for different reasons:
It is important to know that a quality dog food is carefully formulated to meet the caloric needs of the animal. The food provides essential amino acids, vitamin-rich fish oils, and minerals specific to the nutritional requirements of the dog.
Quality foods are complete and balanced for a specific life stage or lifestyle. Adding table scraps or other supplements can disrupt the delicate nutrient balance.
The interaction between minerals is very complex. Fortunately, this area of nutrition has been the focus of extensive research for many years. Research has shown that not only are the individual levels of minerals in a diet important but the proper balance is also. An excess of one mineral might affect the absorption of a second, and lead to a deficiency in that second mineral.
One common way of supplementing is to feed extra meat. However, because meat contains 20 to 40 times more phosphorus than calcium, adding meat to a balanced diet will upset the calcium to phosphorus (or Ca:P) ratio, which is important for proper bone development and maintenance.
This might prompt your pet's body to absorb calcium from the bones in order to reach the right balance. This is often the case in older animals that experience tooth loss due to the reabsorption of bone from the lower jaw. Ca:P ratio should range between 1.1 to 1.4 parts of calcium for each part of phosphorus.
Excess amounts of calcium have been associated with several bone diseases affecting growing puppies. Owners of large-breed puppies, in particular, believe that their puppies require extra calcium for proper development of large bones. Adding yogurt, cottage cheese, or calcium tablets to the puppy's diet will only upset the body's delicate mineral balance.
Remember: Large-breed puppies consume more food and get the calcium their bodies need by eating the recommended portions. The best way to support a normal growth rate is to feed growing dogs a balanced diet using a portion-controlled regimen.
The Association of American Feed Control Officials (AAFCO) regulates the pet food industry and has established certain nutritional requirements for dogs. These requirements are published annually in the AAFCO Manual. Only pet foods that have met the strict criteria established by AAFCO can carry the 'complete and balanced' statement on the label.
The Association of American Feed Control Officials (AAFCO) was formed in 1909 to establish a framework for uniform regulation of the feed industry. Although not a government agency, AAFCO operates within the guidelines of federal and state legislation including laws administered by the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).
AAFCO establishes standards or models for regulations aimed at ensuring that manufacturers provide clear, accurate, and consistent information about animal feed, including pet food.
Every year AAFCO issues an official publication called the AAFCO Manual. This manual, in addition to listing ingredient definitions and feed terms, addresses labeling issues such as label format, ingredient lists, nutrition claims, and guaranteed analysis.
These model regulations are different than laws. However a large number of state governments have adopted AAFCO pet food model regulations into state law.
The “AAFCO statement of nutritional adequacy or purpose,” also called a “nutrition claim” or “complete and balanced statement,” identifies which life stage and/or lifestyle the product has been approved for. Under AAFCO regulations, this statement must be substantiated by the manufacturer.
AAFCO recognizes three methods for substantiating the claim:
AAFCO has outlined very specific protocols, or guidelines, for conducting feeding tests. The protocols specify test criteria including such things as:
Each life stage has its own protocol. Life stages are the same for both dogs and cats and are defined as:
A pet food with an 'All Life Stages' claim can be used from weaning through adulthood. This claim is considered an unqualified (absolute) representation of nutritional adequacy. If substantiated through feeding trials, the protocol for gestation/lactation and growth must be performed sequentially, using the same group of animals.
AAFCO regulations state that specific wording must be used when a diet is intended for special nutritional or dietary needs that require the involvement of a veterinarian for diagnosis, management, and follow-up.
Understanding the AAFCO statements for nutritional adequacy can help customers choose a high-quality diet that provides complete and balanced nutrition for the appropriate life stage of their dog or cat.
