e1“Values of uNDF varied among different forages and within the same type (22.7% ± 4.48%, 20.1% ± 4.23%, and 11.8% ± 3.5% DM for grass hay, alfalfa hay, and corn silages, respectively)”

Other claims from this paper (12)
- Observation Alfalfa hay had an uNDF value of 20.1% ± 4.23% DM.
- Observation Corn silage had an uNDF value of 11.8% ± 3.5% DM.
- Observation The observed uNDF:ADL ratio was 3.22 for grass hay.
- Observation The observed uNDF:ADL ratio was 3.11 for corn silage.
- Association The relationship between uNDF and ADL was not constant and differed for grass hay and corn silage from the 2.4 × lignin value of the Chandler equation.
- Association ADL and ADF gave the greatest correlation with uNDF of any single variable in the whole data set.
- Association The multiple regression equation gave a coefficient of determination of 0.80 for the whole data set.
- Association Within grass hay, the multiple regression equation gave a coefficient of determination of 0.65.
- Association Within alfalfa hay, the multiple regression equation gave a coefficient of determination of 0.77.
- Association Within corn silage, the multiple regression equation gave a coefficient of determination of 0.54.
- Recommendation A regression approach for forage uNDF requires specific equations and different regression coefficients for each forage type.
- Method / resource Direct measurement of uNDF was the best approach for an accurate prediction of iNDF, compared with a regression approach.
