ABSTRACT
Lupin seeds and rapeseed meal
(RSM)
contain relatively high amounts of poorly digestible phytate. Phytase additive
can help in the utilization of nutrients from the diet. The
aim of this study was to determine total tract digestibility
coefficients
of
nutrients and performance results of finishing pigs fed diets containing yellow
lupin
or
narrow-leafed lupin seeds and/or RSM with
similar or increasing levels of phytase. Three experiments were conducted.
In
Experiment I the effect of RONOZYME®HiPhos (100 g/t)
in diets containing narrow-leafed or
yellow lupin
seeds and RSM
on production parameters of fatteners was analyzed. In Experiment II the
effect of phytase RONOZYME®HiPhos (1,000
FTU/t)
in similar diets was analyzed but calcium (Ca)
and phosphorus
(P)
levels in diets were reduced. In Experiment III the
effect of increasing levels of Quantum Bluephytase (0,
5,000,
10,000
and
15,000
FTU/t)
in
diets with yellow
lupin
seeds
with
reduced Ca
and P level on total tract digestibility coefficients
of selected
nutrients
and performance of pigs was analyzed. In none of the experiments the enzyme
additives
included
in
the diet affected pig performance (p >
0.05).
There were no significant differences (p >
0.05)
in apparent total
tract digestibility coefficients of dry matter (DM)
and crude protein (CP). The phytase
additives significantly improved P and Ca
digestibility coefficients (p <
0.05)
in comparison with the control diet, but this improvement was not
linearly related with phytase dosage. By improving
digestibility phytase allows to reduce mineral contents in diets, thus reducing
the cost of pig nutrition.
