'Clearwater': An Eco-Friendly Feed Barley

Summary:
A new barley that benefits the environment as well as farm animals has just been developed. "Clearwater" hulless barley is rich in the kinds of phosphorus -- an essential nutrient -- that pigs, fish and other single-stomached, or "monogastric," animals can use. That's unlike grain from conventional barleys, which contains more of the phytate type of phosphorus, the kind that monogastric animals find difficult to digest.

A new barley that benefits the environment as well as farm animals has been developed by Agricultural Research Service (ARS) scientists and their colleagues.

"Clearwater" hulless barley is rich in the kinds of phosphorus--an essential nutrient--that pigs, fish and other single-stomached, or "monogastric," animals can use. That's unlike grain from conventional barleys, which contains more of the phytate type of phosphorus, the kind that monogastric animals find difficult to digest.

Indigestible phosphorus, leached from manure, can sometimes end up polluting groundwater or streams.

Clearwater builds upon decades of research by plant geneticists Victor Raboy, Phil Bregitzer and others at the ARS Small Grains and Potato Germplasm Research Unit at Aberdeen, Idaho.

Raboy uses conventional plant-breeding procedures to chemically tweak seeds' phosphorus makeup. The work has paved the way for low-phytate barleys, such as Clearwater and a hulled type called "Herald," as well as low-phytate rice, corn and soybeans.

Bregitzer, Raboy and ARS plant geneticist Don Obert collaborated in the Clearwater research with Idaho Agricultural Experiment Station co-researchers Juliet Windes and James Whitmore. A recent article in the Journal of Plant Registrations contains more details.

Clearwater yields are about the same as those of other niche-market barleys, according to Bregitzer. One such market--aquaculture feeds--is already being explored. Approximately 46,000 pounds of Clearwater were shipped to Vietnam earlier this year by the U.S. Grains Council of Washington, D.C., and the Idaho Barley Commission to test Clearwater as a feed ingredient for farm-raised fish.

ARS researchers at Hagerman, Idaho, and Bozeman, Mont., will begin similar investigations with farm-raised rainbow trout this month.

The Idaho Agricultural Experiment Station's Foundation Seed Program at Kimberly has offered Clearwater seed for sale since late 2007. Researchers and plant breeders can contact Bregitzer to obtain, at no charge, small supplies of Clearwater or any of several other feed, food and malting barleys that have resulted from ARS and Experiment Station barley breeding research.
