d)        boron

Step-by-Step Solution:
Step 1 of 3

Chapter 2: Feed Analysis Systems 1 – Proximate Analysis  Objectives: o Explain components of Proximate Analysis (ash, CP, EE, CF) o Calculate NFE o Limitations of each component o Explain and define Detergent Analysis  Proximate analysis components: o Dry matter (DM) o Ash – from this can calculate organic matter (OM); inorganic matter (minerals)  Remains after oxidizing sample; in muffle furnace  % ash = wt after/sample wt x 100%  % organic = 100 - % ash  Problems:  Doesn’t say individual minerals  Some minerals lost when burned (S, Se, Zn, I)  Significance:  Soil contamination of feed or diet indicated  Ca recovered in “ash” residue (mineral)  Minerals in “ash”  Only thing not in ash - water o Crude protein (CP)  Measures N in sample; 2 ways to measure  Kjeldahl N – digests protein, acid base titration  N analyzer (LECO) – oxidize and combusts sample, filters N out  % CP = %N x 6.25  6.25 from the fact that proteins contain 16% N o 100g protein/16g N = 6.25  Can say if sample is contaminated or not
