There are two main reasons why eggs don't make it to the
supermarket shelf: broken eggs that cannot be sold and
eggs that are given a lower score due to visible defects. So
how do we reduce the amount of broken or/and seconds
eggs? In order to improve overall bird health, we must
take a holistic approach and look at the production system
as a whole. The healthier the bird, the more likely they are
to reach their genetic potential and utilize the high-quality
nutrition they are receiving.
By enhancing the hen's nutrition, we can help birds
produce eggs with harder shells, so therefore help to
increase the amount of salable eggs we can produce. It is
widely known that the shell of an egg is made up of mostly
calcium carbonate, magnesium and phosphorus ­ these
are the macros elements. However, if we look closer we
can see micro elements such as copper, manganese, iron
and other minerals can also play a vital role in eggshell
hardness and overall formation.
Another critical point is the form in which these
minerals are actually delivered to the bird. In Alltech
we have created a unique Bioplex® source of organic
trace minerals. Bioplex® resemble those minerals found
naturally and, therefore, we
can achieve better
stability and overall movement across the guy in
comparison to inorganic minerals. The result is better
uptake and absorption, which means the bird can
use them better leading to higher efficiency. This, in
turn, supports bird health and performance, including
improved eggshell strength.
Egg force reader
At Alltech, research and innovation is at the heart of
what we do, both in the laboratory and also in the field. A
recent example of this was the use of an Egg Force Reader
to identify the exact breaking point of an egg. By applying
gradual force to an egg until it cracks, the machine
measures the force required to break the shell. As the
saying goes `You can't manage what you don't monitor'
and this is definitely the case with eggshell hardness. To
date, we have tested over 15,000 eggs in the UK which
represents over 5 million-layer birds.
Trial data
Eggshell strength was measured, using an eggshell
force reader, from 20 to 80 weeks of age. The results
showed that feeding Alltech organic minerals improved
consistency in eggshell strength across the 60-week
period, with a variance of 1.01 kg of force in eggshell
strength, compared to 1.14 kg of force for birds fed
inorganic minerals (see figure 1.0). The results of this was
less seconds and more sales class A eggs.
With increasing pressure from consumers,
supermarkets and packers, along with the high
costs associated with seconds, investing in
bird gut health will pay dividends in ensuring
producers continue to meet these demands.

With an increasing consumer demand for large eggs, along with industry
pressure to extend the laying cycle, producers are under more of a burden
than ever to have a higher proportion of saleable eggs. Niall Brennan, Poultry
