Efek Pemberian Enzim β-Mannanase pada Pakan Berbasis Soy Bean Meal Terhadap Nilai Kecernaan Energi, Kecernaan Protein dan Kadar Imunoglubulin Y Ayam Pedaging
Abstract: Based poultry
Indonesia feed formulation is corn soya, it is mean corn and soy bean meal has
large proportion on the Indonesia poultry feed. The aims of the research to
know the effects of β-mannanase enzyme as feed additive on soy bean meal based
feed on the metabolizable energy, protein digestibility, and concentration
immunoglobulin Y of broiler. This experiment used 20 broilers aged 35th days.
Basal diet was comprised of corn, rice bran, fish meal, meat bone meal, stone
lime, premix, coconout oil, methionine without β-mannanase enzyme (M0). Basal
diet with β-mannanase enzyme 0.016% (M1), 0.033% (M2), 0.046% (M3). The
variables measured were metabolizable energy, protein digestibility, and
concentration immunoglobulin Y. The experimental designed in this experiment
was completely randomized design with 4 treatments and 5 replications. The
results show that the highest energy metabolizable is M3 3358.56±18.08c,
highest protein digestibility is M3 81.01±0.70c, and highest concentration
immunoglobulin Y is M3 5.09±3.21a. It can be concluded that β-mannanase enzyme
in-crease of metabolizable energy, protein digestibility, and decrease
concentration immunoglobulin Y of broiler.
