The amount of feed provided to an animal is primarily determined by its digestive physiology. Digestive physiology refers to how an animal’s body processes and assimilates nutrients from the food it consumes. This includes factors such as the type of digestive system the animal has (e.g., monogastric versus ruminant), the efficiency of nutrient absorption, and specific dietary needs based on metabolic rates.

For example, herbivores have different digestive requirements compared to carnivores because of their different digestive processes and the types of food they are designed to consume. An animal’s ability to digest certain types of feed influences how much must be provided to meet its nutritional needs.

While age, breed, and environment all play significant roles in an animal's overall care and management, they do not directly dictate the fundamental biological processes that govern digestion and nutrient utilization. The digestive physiology is crucial for understanding how much food is necessary for maintaining health and promoting growth or production in animals.
