In-vitro digestibility of crude fiber, crude fat, and nitrogen free extract from mixture Sorgum mutants BMR ( Sorghum bicolor L moench) and Mirasolia diversifolia

Abstract

This research aims aim to obtain a combination of BMR mutant sorghum (Sorghum bicolor L. Moench) and Mirasolia diversifolia in vitro based on crude fiber digestibility, crude fat digestibility, nitrogen-free extract digestibility in ruminant rations. This study employed a Completely Randomized Design experimental framework, involving the application of four treatments, each replicated four times. The treatment consisted of A (80% BMR mutant sorghum + 20% M. diversifolia), B (70% BMR mutant sorghum + 30% M. diversifolia), C (60% BMR mutant sorghum + 40% M. diversifolia), D (50% BMR mutant sorghum + 50% M. diversifolia). The study explored various variables, including the digestibility of crude fiber, crude fat, and nitrogen-free extracts. The analysis revealed a remarkably significant impact (p < 0.01) of the treatment on the digestibility of crude fiber, crude fat, and nitrogen-free extracts. The conclusions that can be drawn from this research suggest that the combination of BMR mutant sorghum and M. diversifolia in vitro was the best in treatment C, with 60% use of BMR mutant sorghum and 40% the use of M. diversifolia with a crude fiber digestibility value of 55.84%, a crude fat digestibility value of 58.47% and a digestibility value of extract material without nitrogen of 57.68%.
