Long-term release rate of a nutritional supplement from a biodegradable polymer matrix

Abstract

For the purposes of ruminant nutrition, a 6-month timeframe is the ideal amount of time for the delivery of trace element and minerals. As a starting element, copper was chosen as it is the most commonly observed trace element deficiency worldwide. Though not every available form of copper is nutritionally equal with each form maintaining its own level of bioavailability. The highest values of bioavailability in the rumen is those forms of copper which are chemically bound to an amino acid, such as copper glycinate (CuGly).
