Biological Quality of Fresh Water Snail of Fermented (Pomacea canaliculata and Pomacea glauca) The Using Different Additivies

摘要

Research has been aim to evaluated the effect of processing "kalambuai" swamp on nutrient composition. This study used an experimental method (2x4x5) factorial by the uses 240 male alabio ducks to designed which was repeated 5 times where each experimental unit consisted of 12 male Alabio ducks aged 2 months. The first factor is the species snails (Pomacea glauca and Pomacea canaliculata) and the second factor is the processing process (steamed, biological silage, acidic and tepsil silage). The results showed that the biological silage processing method gave the best results and improved nutrient composition, protein efficiency ratio, metabolic energy, protein digestibility, amino acid composition and amino acid digestibility.
