The type of animal indeed plays a crucial role in determining the nutrient requirements in feeds, primarily because different species possess varying digestive systems and metabolic rates. Each species has evolved specific anatomical and physiological traits that influence how they process and utilize nutrients. For example, ruminants like cows have a multi-chambered stomach that allows for fermentation of fibrous materials, enabling them to utilize plant fibers that monogastric animals, like pigs, may struggle to digest effectively.

Additionally, metabolic rates differ widely among species, influencing how quickly animals require energy, protein, vitamins, and minerals. Carnivores, for instance, have different protein and fat needs compared to herbivores, which may require higher fiber content in their diet. These distinctions highlight the importance of tailoring feeding strategies to meet the unique nutritional demands of each species, ensuring optimal health, growth, and production.

In contrast, other options suggest a uniformity in nutrient needs across species or imply that factors such as age alone dictate these requirements, which overlooks the complex interactions of biology and nutrition specific to each animal type.
