How many licks does it take to get to the centre of the salt block?
1. How many licks does it
take to get to the
centre of a salt block?
2. •Ingredients:
-SodiumChloride
-Calcium Iodate
-Cobalt Carbonate
-ultramarine coloring
• The Role of Salt:

• Composition of a blue
Cobalt Iodine Salt Lick:
–
–
–
–
Salt (NaCl): 99%
Cobalt: 120ppm
Iodine: 180 ppm
Traces of other
minerals
Regulates blood pressure
Maintains body acidity
Involved in muscle contraction and nerve transmission
Chlorine in stomach acid
Cobalt for vitamin B12 synthesis in the rumen
Iodine for thyroid hormones and metabolism
3. • White: good old plain
sodium chloride, NaCl
and trace elements
• Red: NaCl, trace
elements, and
additional iodine
•Yellow: sodium chloride
and trace elements with
additional sulfur
• Marbled: Himalayan
salt, with high levels
of minerals
• Blue: sodium
chloride with trace
elements and extra
cobalt
•Brown: sodium chloride
with additional minerals

5. • Cows will drink around • May lick more than 1879
45L of water per day,
times in one visit to the
up to 120 L
salt block
•Can produce up to 200L of saliva every day (for
chewing cud of course)
•Require 45 g/day or
315 g/week or 16380
g/year – that’s less
than one whole salt
block
6. 22.2 cm
• Grams removed from block with every lick:
(20468g – 20356g = 112grams)
= 112 g
= 0.06 g/lick
1879 licks
• Find volume of the block by multiplying volume of
1/8th of a sphere by the density of the block. First, find
the radius of the circle from the block’s dimensions.
7. 22.2 cm
1. Find Radius of Sphere using
Pythagoras's Theorem:
√(11.1cm)2 + (12.4cm)2 =16.6 cm
2. Find Volume of 1/8th Sphere:
4/3 π r3 = 4/3 π (16.6cm)2 x 1/8 = 2411.15 cm3
3. Multiply by density of block:
2411.15 cm3 x 2.17g/cm3 = 5232 g
8. • Licks to get to
the center = 5232.2 g
0.06 g/lick = 87200 licks
• Time to get to the center: (assuming 1 lick per
second)
=87200 licks x 1 second x 1 hour
1 lick
3600 sec
= 24.2 hours!
