The Effect of Silage Microbial Inoculants on the Silage Quality of WL358HQ Alfalfa

In order to explore the effect of different silage microbial inoculants on the silage quality of WL358HQ Alfalfa (<i>Medicago sativa</i> L.), the test consists of the following six treatments: Xinlaiwang I-straw silage inoculant (A), Xinlaiwang I-alfalfa silage inoculant (B), Zhuang Le Mei silage inoculant (C), Baoshiqing (D), KOFASIL S lactic acid bacteria silage inoculant (E) and distilled water (F). Nutritional and fermentation indexes were determined after 60 days of natural fermentation at room temperature. The results showed that the contents of crude protein (CP) and water-soluble carbohydrate (WSC) of the B treatment were higher than other treatments. The Relative Feed Value (RFV) of the B treatment was high, the lactic acid (LA) content of the B treatment was significantly increased (<i>p</i> < 0.05) and the contents of neutral detergent fiber (NDF), acid detergent fiber (ADF), pH and ammoniacal nitrogen/total nitrogen (AN/TN) of the B treatment were low. The results showed that treatment B has the best ensilage effect and the highest ensilage membership function, which can effectively improve the quality of WL358 alfalfa silage.
