Abstract

More than $1,000,000 worth of almond hulls have been marketed annually by California almond growers in recent years. This by-product of the almond industry is used mainly by livestock producers in beef cattle feeding operations. New methods of processing almonds have resulted in a feed by-product now consisting of almond hull and shell mixtures. Studies reported in this article indicate that hull-shell meal supplies little or no protein and is also a poor source of phosphorus and fat. However, the hull-shell mixtures are high in nitrogen-free extract, sugars and potassium. The money value of Nonpareil variety almond hull-shell meal containing an average of 18% fiber is about 58% that of barley.
