[Effect of enzyme mixtures in broiler diets of barley, rye or wheat].
In three trials with a total of 4120 male and female broilers, kept on floor or in cages maize has been partly replaced by barley, rye or triticale and different combinations of enzymes were fed. The supplementation of cellulases with mainly glucanase in barley based diets has had no significant influence on growth performance. In case of diets with 20% rye the addition of cellulases with mainly hemicellulases resulted in 5% higher live weight gains and a better feed efficiency (5%) on average of two trials. The negative influence of rye feeding on excrement constitution was lowered and the dry matter content of excrements increased by 1.3%. In diets based on triticale the growth performance of broilers was insignificantly better. The addition of enzymes did not influence the proportion of different body fractions as well as the crude nutrient content of edible carcass.
