Gross energy, also known as the heat of combustion, is the total chemical energy released when a feedstuff is completely burned. It is the foundational measurement in feed energy evaluation for livestock and other animals, providing a starting point for assessing nutritional value. Understanding how this measurement is performed is crucial for animal nutritionists and producers.

Over half of an animal's body is composed of water, a fundamental component of the diet that is often overlooked despite its critical role in survival. In addition to this vital element, a balanced diet requires six other key components, raising the important question: what are the 7 nutrients for animals?.

Creatine, derived from the Greek word for 'meat' ('kreas'), is found in high concentrations in the skeletal muscle of animals. This fact answers the fundamental question, do carnivores have creatine, and sets the stage for a deeper look into dietary sources and internal production.

With a body that can weigh up to 200 tons, the blue whale consumes up to 7,900 pounds of krill per day. The specific diet of a 'giant' varies dramatically depending on the species, but answering the question of what does giant eat in a day requires looking at several of the world's most massive animals.

According to the Food and Agriculture Organization of the United Nations, accurate fat measurement is critical for evaluating the nutritional value of food and animal feed worldwide. Understanding the difference between fat and crude fat is essential for correctly interpreting nutrition labels and assessing product quality, a distinction that primarily hinges on the analytical method used.

According to the RSPCA, mice are opportunistic omnivores, meaning they consume both plant and animal-based foods. This raises a critical question for many pet owners: can mice be vegan? While a plant-based diet is possible for some species, it requires careful management to prevent deficiencies.

Carbohydrates typically comprise 60 to 70 percent of diets for animals like dairy cattle, making them the most significant source of dietary energy. This macronutrient class is not only crucial for powering daily activities but also plays a fundamental role in maintaining gastrointestinal health and metabolic processes.

Although most dietary carbohydrates originate from plants, animals are also a source, primarily providing glycogen and lactose. Understanding what are animal derived carbohydrates sheds light on unique aspects of energy storage and nutrient availability across the animal kingdom.

Approximately 99% of all animal species rely on the ingestive mode of nutrition, a process also known as holozoic nutrition where organisms consume complex organic material and break it down internally. This fundamental method of feeding is what separates organisms like humans, dogs, and amoebas from plants and fungi, and it is a multi-step journey from food intake to waste removal.

Over 97% of all animal species are consumers, meaning they must obtain energy by consuming other organisms. This fundamental biological principle forms the basis for understanding what does heterotrophic and ingestive mean, concepts that describe how animals and other organisms obtain their nourishment.
