Abstract

This study assessed how King Grass (Pennisetum purpureophoides)'s ensiling qualities and chemical makeup were affected by lactic acid bacteria (LAB). Four treatments were used: a control (KC) with 2 mL/kg of sterilized water, commercial Lactobacillus plantarum (KP), L. plantarum isolated from Napier Grass (KN), and L. paraplantarum isolated from Italian Ryegrass (KI). Lactic acid (LA), ethanol, and propionic acid (PA) levels in LAB-treated silages were significantly higher (P<0.05) than in the control. Nevertheless, there was no discernible difference (P>0.05) in dry matter (DM) or PA between treatments at the conclusion of the ensiling period. Acetic acid (AA) and ammonia nitrogen/total nitrogen (NH₃-N/TN) decreased (P<0.05), although LA and ethanol increased significantly (P<0.05). LAB, mold, and yeast populations also showed significant changes (P<0.05).
