What is the preferred nutritional characteristic of fats in pig diets?

In swine nutrition, fats are primarily sought after for their ability to provide a higher energy content. Fats are more energy-dense than carbohydrates or proteins, offering approximately 2.25 times more energy per unit weight. This high-energy density is crucial in pig diets as it allows for the provision of sufficient calories without having to increase the volume of feed significantly.

When formulating diets for pigs, energy balance is vital for optimal growth, reproduction, and productivity. Fats help in achieving this balance effectively, making them a preferred source of energy. Additionally, fats can aid in improving palatability, which can enhance feed intake.

While fats can play a role in various biological functions, such as aiding in the absorption of fat-soluble vitamins, their primary nutritional characteristic that drives their inclusion in pig diets is their ability to deliver concentrated energy efficiently.
