The Effect of Corn Stover and Red Calliandra in Silage on the Dry Matter, Organic Matter, in Vitro Digestibility

Abstract

This study seeks to determine the impact of corn stover and Red Calliandra on dry matter, organic matter, and in vitro digestibility. This research employed a completely randomized design (CRD) featuring four treatments and five replicates: P1 (90% corn stover + 10% Calliandra calothyrsus), P2 (80% corn stover + 20% Calliandra calothyrsus), P3 (70% corn stover + 30% Calliandra calothyrsus), and P4 (60% corn stover + 40% Calliandra calothyrsus). We used analysis of variance (ANOVA) to look at the data and then Duncan's multiple range test to look at the results. The observed variables included dry matter, organic matter, dry matter digestibility, and organic matter digestibility. The findings indicated that the combination of corn stover and Calliandra calothyrsus significantly influenced dry matter digestibility and organic matter digestibility (p < 0.05), although it exerted no significant impact on dry matter and organic matter content (p > 0.05). The combination of 80% corn stover and 20% Calliandra calothyrsus (P2) produced the optimal silage, with dry matter digestibility of 54.03% and organic matter digestibility of 59.72%. Higher inclusion levels (30-40%) significantly reduced digestibility (p < 0.05) due to the anti-nutritional effects of tannins, while dry matter and organic matter content were not significantly affected (p > 0.05).
