Butyric acid in silage
WebButyric acid - Butyric acid produces a rancid butter smell and taste. High concentrations (greater than 0.5%) indicate the silage has undergone an undesirable, Clostridial fermentation and the resulting silage is lower in nutritive value because soluble nutrients have been degraded. These silages may result in lower feed intakes and milk ... WebOct 13, 2024 · Compared with the AL silage, the 1% sucrose addition significantly decreased (p < 0.05) the acetic acid, propionic acid, and butyric acid content for each ensiling duration. In particular, the concentration of butyric acid was the lowest at 60 days. Assessment of the Feed Value
