Experimental data shows that the percentage of
saleable eggs increased significantly in flocks kept
past 90 weeks due to a 30 percent reduction in
broken and shell-less eggs.
Split feeding also improves sustainability, with
less nitrogen (10 percent), phosphorus (5 percent)
and calcium (4.1 percent) excreted. This is thought
to be due to a lower daily nutrient intake and more
efficient use. Split feeding results in more profitable
egg production due to reduced cost of production,
improved egg shell quality, increased number of saleable eggs and greater sustainability. The caveat of this
system is that two feed bins are required to deliver the
two formulations, along with a feed weighing system
and an automated system to change the feeds, meaning
significant investment for existing housing systems
and design considerations for those newly built.

Fiber, fiber, fiber
A lot is written about the importance of fiber in diets
for all livestock and, when it comes to laying hens, it's
not just the gut that benefits but also the feathers. This
key welfare indicator is particularly important as some

The Specht aviary system with nests in the middle
is a further development of laying batteries and floor
management system that Specht has been producing
since 1967.
Good reasons for the Specht Varia system with middle nest:
>> Optimum stocking density per house because of usable
area on several levels.
>> Integrated LED-lights in the system.
>> Group laying nest in the middle with nipple drinking lines.
>> Little mislaid eggs due to the highest possible
acceptance of the nests by the layer hens.
>> Automatic manure removal with PP-belts.
>> System with a good overview and more space per hen.
>> Arm length (90 cm) up to the middle.
Useable space on several levels enables an optimal
stocking density. The use of floor space contributes
to animal-friendly husbandry.
