Nutritive value of the soluble and insoluble fractions of the foliage of Gliricidia sepium (Jacq.) Kunth ex Walp
Abstract
Nutritional potential of water-soluble and water non-soluble leafage of Gliricidia sepium, tested by ruminant degradability and in vitro gas production techniques, was studied.
Ruminant degradability of dry matter and nitrogen showed high values, i.e., 54,5 to
81,9 % and 73,2 to 92,1 %respectively. Lower values were registered in leafage with an older rebudding age or stem inclusion. Both water-soluble and water-nonsoluble leafage are nutritionally relevant. Water-soluble leafage nutritional contribution was higher during the first twelve-hour fermentation process. G. sepium leafage nutritional potential derives from its gradual nitrogen and energy supply to rumen micro-organisms.
