Improve the Quality of Corn Husk on Chemical Composition and In Vitro Digestibility

Abstract

This study aimed was conducted to evaluate of quality improvement of corn husk by using essential microbial activators PD1 and microorganism (EM) on chemical composition, gas production and estimate parameter. A Completely Randomized Design was used in this study. The experimental diet was divided into 5 groups follow by: untreated corn husk (T1), corn husk ensiled with PD activator 1 (PD1) at 0 and 14 days (T2 and T3) and corn husk ensiled with essential microorganism (EM) at 0 and 14 days (T4 and T5) with a group of 3 repetitive. The chemical composition and in vitro gas production were determined. The results were shown that crude protein content of T2, T3, T4 and T5 was significantly higher than T1 (P<0.01). But dry matter, crude fiber and cellulose of T1 were significantly higher than all treatments (P<0.01). Moreover, ensiling corn husk with PD1 at 14 days tended to be lower ME when compare with other treatments (P=0.06). According to the results of this research, Improvement of quality improvement of corn husk by using essential microbial activators PD1 and microorganism (EM) with an increase in level of crude protein and ether extract content. And also resulted of crude fiber, NDF, ADF and cellulose this is a decrease.
