According to the National Research Council, dietary energy is the most important component of an animal's diet after water. Understanding the difference between digestible energy (DE) and metabolizable energy (ME) is fundamental to accurately assessing feed quality and ensuring proper nutrition for livestock and pets.

According to European Union regulations, glycerine is labeled as providing 2.4 calories per gram, which differs from U.S. labeling rules. This variation highlights the complexity in determining what is the energy value of glycerine, a sugar alcohol widely used in the food industry.

Over 50% of U.S. dogs are overweight or obese, a statistic that highlights the importance of accurate portion control. Understanding how to calculate the calories in your dog's food, also known as its Metabolizable Energy (ME), is a critical step toward maintaining your pet's ideal body weight and ensuring a long, healthy life.

According to Oregon State University's animal nutrition guide, metabolizable energy is the energy remaining after losses from feces and urine have been accounted for. So, is metabolisable energy the same as digestible energy? The short answer is no, and understanding the distinction is crucial for proper animal diet formulation and performance.

According to animal nutrition research, gross energy in feed is never fully utilized by an animal. Understanding what is the difference between digestible energy and metabolizable energy is crucial for properly formulating diets and optimizing animal health and production. This distinction accounts for energy lost through waste products and is a more accurate measure of available energy than total or gross energy.

According to the Atwater system, one gram of protein provides approximately 4 kilocalories of metabolizable energy, though it is not the body's preferred source of fuel. This means that while protein can be converted into usable energy, it is primarily reserved for more critical functions like building and repairing tissues.

The energy an animal derives from its food is a critical metric in nutrition, and approximately 19% of a ruminant's digestible energy may be lost before it can be fully metabolized. Digestible energy (DE) quantifies the portion of an animal's dietary energy that is actually absorbed, excluding the energy lost through feces.

According to nutritional studies, humans and animals lose up to 10-15% of total food energy through feces and urine. This unabsorbed portion is why the total energy content of food, measured through combustion, is not the same as the energy an organism can actually use, a value known as metabolizable energy.

Over 65% of the cost of raising livestock is attributed to feed, making energy the most expensive component in an animal's diet. This is why understanding exactly how we measure the amount of energy in feed is crucial for formulating cost-effective rations and optimizing animal health and productivity.

According to the Food and Agriculture Organization (FAO), the energy available to the body is less than a food's total energy, as it must account for losses during digestion and excretion. This usable energy is known as the metabolizable fuel value, a crucial concept in nutrition science that provides a more accurate measure of the body's energy intake from food.
