Protein fractions (Cornell system) of lucerne dried or ensiled with different additives

Effects of formic acid, formaldehyde, tannic acid or mixture of each two of the additives on five protein fractions based on the Cornell Net Carbohydrate and Protein System (CNCPS) in hay and ensiled lucerne (Medicago sativa) were studied. After 35 d of ensiling, the additives significantly reduced fraction A in the ensiled forages. Fraction B1 in all of the additive-treated silages was significantly higher than that in control silage. Large amounts of true protein in the formic acid/ formaldehyde treated- and tannic acid/formaldehyde treated-silages were fractions B3 and fraction B2, respectively. No difference was observed on fraction C content between the control silage and silages treated with additives except for the formaldehyde or tannic acid treated-silages.
