Could discrepancy in sodium in a feed mix indicate more fundamental faults?


Discrepancy between analysed and guaranteed sodium content in 14 feed mixes showed that the frequency of faults ranged from 1.4 % to 16.8 %, and had, in any mixture, a magnitude of 1.15 times the value of the sodium level (2-12) in gkg-1. Excessive faults were equally distributed on all sodium levels. Deficient faults were predominant on nominal levels higher than 3 gkg-1 which indicated a shortened inclusion of sodium rich feeds like fishmeal or bonemeal Faults in high levelled sodium mixes increased with time (8 years) while the fault frequency in the most important mixes decreased. The best balanced mixes were produced in the most efficient agricultural regions. The most important mixes were homogeneous with lowest fault frequency (2 %).
