Fed to dogs whole daily meal. Dietary protein.
Rich in nutrients dogs foods. Hill's Science Plan Adult. A requirement for dietary protein actually represents the need for essential amino acids and adequate nonessential amino acids to maintain body protein and to supply nitrogen for the synthesis of nonessential amino acids and other essential nitrogen-containing. This requirement is commonly expressed as a protein requirement because amino acids and nitrogen-containing compounds are most typically supplied in the diet in the form of intact protein.
Adult animals require dietary protein to maintain whole-body protein turnover. This turnover represents the synthesis and breakdown of proteins in all tissues of the body, including skin, hair, skeletal muscle, digestive enzymes, hormones, serum transport proteins, and mucosal cells. It is the sum of the losses of all of the body's individual proteins and nitrogen-containing compounds that ultimately determines an individual's daily protein (amino acid) requirement.
Young animals have the same maintenance requirements as adult animals, plus an added requirement for the deposition or growth of new tissue. Protein in the diets of adult dogs, adult cats, puppies, and kittens is necessary for the replacement of protein losses in the skin, hair, digestive enzymes, and mucosal cells, as well as amino acid losses from normal cellular protein catabolism. Puppies and kittens also require protein for growth.

Historically, the response criteria that have been used to determine protein requirements in dogs and cats are nitrogen balance and growth rate. Nitrogen balance studies are based upon the fact that protein, on the average, contains 16% nitrogen. The nitrogen contents of food, feces, and urine are commonly measured using analytical tests. Measuring nitrogen intake and excretion provides a rough estimate of the body's protein status. Nitrogen balance is calculated as: Nitrogen balance = Nitrogen intake from food - Nitrogen excretion through urine and feces. The nitrogen in the feces is comprised of unabsorbed dietary protein and nitrogen from endogenous sources, such as intestinal cells and gut microflora. Urinary nitrogen is composed primarily of urea, which is the end product of amino acid catabolism. Further nitrogen losses occur from desquamated cells of the skin surface, hair, and nails.
However, these losses are very difficult to measure and are usually not considered when measuring nitrogen balance in experimental studies. Requirement studies with growing animals use maximum positive nitrogen balance and growth rate as response variables to indicate an adequate level of protein in the diet. Studies of adult companion animals at maintenance use zero nitrogen balance to indicate dietary protein adequacy. Zero nitrogen balance provides an indirect measure of whole-body protein turnover and suggests that the body's daily loss of protein is replaced by intake, without a net gain or loss in total body protein.
Although the majority of requirement studies have used zero nitrogen balance to assess the protein requirement of adult animals during maintenance, it is important to recognize that there are certain limitations to the use of the nitrogen balance technique. First, nitrogen balance does not provide information regarding the adequacy of individual amino acids. Therefore amino acid requirement studies have been conducted independently of protein requirement studies. Second, the minimum level of protein needed to maintain zero nitrogen balance may not be adequate to promote optimal performance and health.

The determination of the exact protein requirements for dogs and cats is a difficult task because many factors affect an individual animals need for protein. Dietary factors that affect protein turnover (nitrogen balance) include protein quality and amino acid composition, protein digestibility, and the energy density of the diet. In addition, an animal's activity level, physiological state, and prior nutritional status can all influence protein requirement as determined by nitrogen balance, wholebody protein turnover, or growth rate.
An animal's protein requirement varies inversely with the protein sources digestibility and with its ability to provide all of the essential amino acids in their correct quantities and ratios. As protein digestibility and quality increase, the level of protein that must be included in the diet to meet the animal's needs decreases. Early protein requirement studies with dogs and cats used either purified or semipurified diets; the protein and amino acids in these types of diets are highly digestible and available. In contrast, most of the protein sources used in commercial pet foods have comparatively lower digestibility coefficients.
However, when the fat content of the diet was increased to 30%, 29% crude protein was necessary to support maximal growth. The reason for this change relates to an animal's tendency to eat to satisfy its energy needs. Provided that these controls are in place, an animal will naturally consume less of a more energy-dense ration.
Pet owners who use portion-controlled feeding regimens usually adjust quantity according to their pets body weight and/or growth rate. Therefore portioncontrolled feeding schedules are still regulated according to a pet's energy requirements. When lower quantities of food are fed because of greater energy density, protein must contribute a higher proportion of the diet so that the animal is still able to meet its total protein needs. Although protein is the most commonly used example, this relationship with energy also applies to all other essential nutrients.
