Swine Nutrients

Pigs (and any other animal for that matter) require a balanced mixture of nutrients in order to grow and produce. This fact sheet will discuss nutrients, in what feeds nutrients are found, and ways to mix feed to meet a pig’s nutrient requirements.

Both swine and humans are omnivores. Carnivores and omnivores possess a simple monogastric digestive system. Dogs, cats, reptiles, fish, and pigs all share this most-simple of digestive systems.

As pig producers, we want pigs to grow quickly. Cereal grains make up the high-energy portion of animal diets and provide a lot of calories per pound of feed. They are an important component when pigs are fed for maximum growth, production, or fattening for slaughter.

Before we get into individual protein sources, we need to have a brief review of the protein digestion process.

Some vital functions of water include temperature regulation, transport of nutrients and waste, a multitude of metabolic processes, and lubrication throughout the body.


Cereal grains and soybean meal contain a little bit of fat, but fat is sometimes added to swine diets in order to increase the energy density.

In order to grow and produce most efficiently, pigs need minerals in their diets that aren’t supplied by grains.

Vitamins are divided into two classes – fat soluble (A, D, E, and K) and water soluble (B Complex and C).

Pigs need specific nutrients to grow, produce, and thrive.
