Effect of Lignin Peroxidase Enzyme on Feed Values of Different Straws

Abstract

The purpose of this study was to determine the effects of various feed additives and lignin peroxidase (LiP) enzyme application on the quality and digestibility of some straws. Three different straws (wheat straw, soybean straw and sorghum straw) with 4 different treatment groups (Control, 4% urea, 10% molasses and 14% urea + molasses) were used in the study and 8 treatment groups were established for each straw and results were analyzed according to randomized factorial design. Daisy incubator was used to determine the in vitro true digestibilities (IVTD) of straw. In this study, molasses treated straws were the best among all treatment groups in organoleptic analyze, it was also found that sorghum straws gave the best results. Research Article Sorghum straw silage ranked first in terms of dry matter digestibility (DMD), dry matter intake (DMI) and the relative feed value (RFV) (P<0.001). In this study, it was found that the LiP enzyme did not significantly affect the IVTD and in vitro digestibility of ADF (P>0.05) in straws. LiP enzyme increased lignin digestibilities for all treatments. As conclusion, sorghum straw was found to have higher feed value compared to other straws used in present study.
