Question

1. A recent hay analysis came back from a commercial lab with the following values. Please identify and describe at least 2 potential errors in the analysis based on your understanding from this class. Analysis (all expressed on a DM basis): 86% DM, 30% CP, 44% NDF, 52% ADF, 8% NSC (non-structural carbohydrates), 5% ash, 5% lignin.

Answer 1

here the value of ADF (acid detergent fiber) is higher than NDF (neutral detergent fiber). ADF represents the fiber that is poorly digested by animal and as this value increases digestibility decreases. Also the RFV (relative feed value ) is more than 104, thus the sample is lesser quality in terms also.
