Opportunities for using high-fiber feed ingredients

There are a number of high fiber ingredients available to swine producers. High-fiber ingredients are often available at relatively low costs because these ingredients cannot be used in the biofuel industry. High-fiber ingredients are, therefore, often attractive in feed formulation to reduce diet costs.

Research Report

Amino acid digestibility and energy concentration of copra expellers, palm kernel expellers, and palm kernel meal fed to growing pigs

Copra and palm kernel co-products are commonly fed to ruminant animals in some parts of the world. However, very limited research has been reported on the use of these ingredients in swine diets. No values are listed in the NRC (1998) for copra expellers, palm kernel expellers, or palm kernel meal.

Copra expellers are produced when coconut oil is mechanically expelled from coconut meat, or copra. Likewise, palm kernel expellers are produced from mechanical expulsion of oil from the nut of the fruit of the palm tree, whereas palm kernel meal is produced when palm kernel oil is removed by solvent extraction. All these ingredients have relatively high concentrations of fiber and a relatively low concentration of amino acids. In contrast, copra and palm kernel products have a high concentration of fiber.

May 2: Valuing feed ingredients, part 1: Feed ingredient composition

In Part 1 of a presentation on methodology for valuing quality of feed ingredients, Dr. Hans H. Stein discusses the nutrient composition of ingredients.
