Einsatz eines Nicht-Stärke-Polysaccharid (NSP) hydrolysierenden Enzyms als Futtersupplement bei Legehennen
Abstract. Title of the paper: Use of a non-starch-polysaccharide (NSP) hydrolysing enzyme as feed Supplement for laying hens
The present study investigates the use of a non-starch-polysaccharide (NSP) hydrolysing enzyme as feed Supplement for laying hens. Furthermore it should be tested in which extent a multi enzyme complex at two diets (24 % barley, 23 % rye, 23 % sunflowerseeds vers. 19 % wheat, 25 % rye, 20 % sunflowerseeds) with two dosages can influence Performance parameters, nutrient digestibility and metabolizable energy at laying hens The investigations comprised six experimental diets. Besides a Performance trial with 60 animals per treatment a balance study with six animals per tratment were carried out. At the Performance trial neither between the experimental diets nor between the enzyme dosages statistically differences could be found at the Performance parameters. A positive influence of the enzyme supplementation on the reduction of dirty eggs could be observed in both experimental rations; in the course of which the higher enzyme dosage had a bigger effect. At the balance trial no response of the addition of the multi enzyme complex on nutrient digestibility and metabolizable energy could be found.
