Sodium chloride
- Identification
.....CAS / EINECS No:
7647 - 14 - 5 / 231 - 598 -3

Process
Sodium chloride is obtained from underground rock salt deposits
from brine and from seawater (marine salt). Process steps can
be: dissolution, evaporation, washing, separation, drying, calibration,
grinding, treatments, etc.

- Specific
advantages
Na and Cl source
Concentration elements
100 %, highly assimilable
(bioavailability
90% - 100%)
Widely available,
economically attractive
Stable
Wide range of qualities
adapted to different uses (for example particle
size finely granulated
for premix, poultry feed)
Trace of mix homogenicity
of compound feed
Appetizing agent
Conservation agent
for feed and forages (hay, silage)
Ideal carrier of
many feed additives (minerals, trace elements) in particular
as ‘salt
lick’
Free choice supplementation
(animals have a definite appetite for salt).
