They are often very high in calories, carbohydrates and fats and not terribly digestible by dogs.
Crude protein is good for dogs. Crude protein forms an essential component of a healthy, balanced dog diet. Crude protein in your dog's food is a primary source of amino acids and is easier for dogs to digest than other protein sources.
Dogs do not get the all-natural variety of crude protein in their food because it is not necessary for health and diet. Dogs also eat food from different sources for different reasons. Some dogs need to eat at a very high protein level to meet the needs of their activity level. Others need a higher protein level to give their muscles the protein they need to repair damage or build up muscle mass.
They also need more protein to help them build muscle. When used in dog food, crude protein is often given as part of a blended mix. The non-grain ingredient is highly processed and inedible for humans. A blended blend has many ingredients, including vegetable proteins, with the majority of the mix made up of raw ground meat. Sometimes, all the ingredients in the blend are raw ground meat, making it very rich in nutrients. Worth a look : The most frequently asked dog food questions.
To understand what crude protein is and its use in dog food, we need not look any further than the modern, commercial dog food diet vs dogs who are fed on raw meat alone. There are two measurements for protein content in food human or dog food : crude protein and true protein.
Crude protein is calculated by measuring the nitrogen content of the particular food. To get a simple understanding of what crude protein is and its role in a dog's diet we need to explore the role of protein in dog food more generally.
As a dog ages, its protein requirements decrease and the amount of crude protein they need to eat each day drops. Dried brewers grain. Corn gluten meal. Sorghum Jowar grain. Wheat grain. Corn Maize grain. Peanut meal. Soyabean hulls. Copra meal. Dried alfalfa leaves. Rapeseed meal. Rice bran. Wheat bran. Beet molasses. Wheat middlings. Sunflower meal. Poultry manure. Therefore, be sure to ask the laboratory if their database for your particular sample is extensive enough to ensure accurate results, particularly if you are analyzing less common feedstuffs.
The primary focus of this module is on understanding and applying the results from a commercial feed analysis. Table 1 lists common nutrients and the units in which they are reported. The following explanations are categorized by nutrient and define terminology that one will receive on a feed analysis. Dry Matter DM : Dry matter is the moisture-free content of the sample. Because moisture dilutes the concentration of nutrients but does not have a major influence on intake aside from severe deprivation , it is important to always balance and evaluate rations on a dry-matter basis.
Crude Protein CP : Crude protein measures the nitrogen content of a feedstuff, including both true protein and non-protein nitrogen. In ruminants, evaluation of the fraction that is degradable in the rumen, degradable intake protein DIP , versus the rumen-undegradable fraction, undegradable intake protein UIP , is also important. However, the rumen degradability of protein is not measured in most commercial labs.
Degradable Intake Protein DIP : The fraction of the crude protein which is degradable in the rumen and provide nitrogen for rumen microorganisms to synthesize bacterial crude protein BCP which is protein supplied to the animal by rumen microbes.
DIP also includes non-protein nitrogen found in feeds or ingredients. Commonly called "bypass protein" because it bypasses rumen breakdown and is mainly digested in the small intestine. Bypass protein is utilized directly by the animal because it is absorbed as small proteins and amino acids. Feedstuffs with high ICP are often discolored and have distinctly sweet odors in many cases.
Adjusted crude protein ACP; see below values should be used for ration formulation. Digestible Protein DP : Reported by some laboratories, do not use without the guidance of a nutritionist. Digestible protein values are not needed for most ration formulation because nutrient requirements and most formulation tools are already adjusted for protein digestibility.
