The objective of the study was to
determine the effects of two enzyme preparations
containing b-glucanase and xylanase activities on barleyand wheat-based diets, respectively, for broilers, in
combination with flavomycin. In addition, the stability
of the enzyme preparations after pelleting was measured. Temperatures recorded during the pelleting
process reached 75 to 80 C, and the activities recovered
with respect to the amounts present in the mash feed
before pelleting were 80% or higher.
Two performance experiments were conducted simultaneously under the same conditions over 6 wk. In
addition, intestinal viscosity and incidence of vent
pasting were measured and carcasses were eviscerated
to determine abdominal fat, carcass yield, and percentage weight of intestines and viscera. Twenty-four pens
(12 per sex), each containing 75 chickens were used in each experiment. Wheat- or barley-based diets were
supplemented with flavomycin and a xylanase or a bglucanase preparation, respectively, in a 2 · 2 factorial
arrangement of treatments. In the wheat diets, xylanase
and flavomycin improved feed efficiency, in parallel
with a reduction of intestinal viscosity. Xylanase
reduced the incidence of vent pasting and the percentage viscera, especially of intestines, and increased
abdominal fat. In the barley diets, b-glucanase and
flavomycin improved feed conversion. b-Glucanase also
reduced intestinal viscosity and vent pasting. Both bglucanase and flavomycin reduced percentage intestines,
but the effects were not additive. In general, the effects
of the enzyme preparations and flavomycin were
independent, except for percentage intestines with b-glucanase.
