Different Composition of Indigofera zolingeriana and Corn Stover Mix on Silage Quality and Fermentation Characteristic

Abstract

Agricultural by-products utilization is one of the solutions for feed shortage problem. Agricultural by-products have high potential to be used for feed, but its utilization is limited by the low nutrient quality. Silage is a type of byproduct utilization that can increase the nutrient quality. Adding good quality forage to silage may augment the nutrient content and quality of silage. This study aimed to analyse the quality and characteristics of different composition percentages of corn stover (CS) and Indigofera zolingeriana (IZ) mix silage. The complete randomized design was applied in this research with four treatments consisting of T1 (90% CS + 10% milled corn), T2 (80% CS + 10% IZ + 10% milled corn), T3 (70% CS + 20% IZ + 10% milled corn), and T4 (50% CS + 40% IZ + 10% milled corn). The variables observed were pH level, dry matter, crude protein content, and Fleigh score. The results show that 10%, 20% and 40% Indigofera zolingeriana addition in silage yield high DM content (30,04±0,80, 30,85±2,00 and 33,03±0,99 respectfully) and increase CP content (2,87±0,04, 3,20±0,19 and 3,77±0,16 respectfully), and Fleigh score 150,5±0,9, 138,7±10,6 and 120,4±4,9 respectfully.
