What is NutriOpt split-feeding ?
A feed system to optimise egg production.
Provide a more precise supply of nutrients to meet with the requirements of the specific phases of egg
formation.
Hens are fed two different diets per day:Morning diet
: meets the requirements for egg production.
Afternoon diet:
meets the requirements for eggshell formation.

NutriOpt split-feeding – BenefitsImprove
eggshell quality.More persistency and saleable eggs ( +2 eggs/ hen).
Reduction of feed cost ( - 6 € / MT feed).Reduce the excretion of nutrients by faeces.

Different formation phases of the egg
30
minutes after the current oviposition the next ovulation
occurs.
During the first 3h 30min the white is
produced.
After forming shell membranes, the eggshell begins to be
formed => Ca deposition
(20 hours
).
Hens lay >
90% of
their
eggs during the
morning.
Interval
between
ovipositions => 24±1 hours.

Trouw Nutrition R+D
9 trials ( 2005 – 2012) performed focused on:
Determine
optimal nutrient levels in
the morning and afternoon diets. Demonstrate the benefits obtained with NutriOpt
split-feeding
:
Improve the persistency, more saleable eggs.
=> improve eggshell quality.
Feed cost savings.
Reduce the excretion of nutrients.

NutriOpt split-feeding - Summary
NutriOpt split-feeding brings the optimal supply of nutrients
to meet the needs of hens in the egg formation process . Brings a
more profitable and sustainable egg production,
with a lower production cost. These benefits can be achieved easily with
Trouw
Nutrition´s NutriOpt system, utilizing all the knowledge from R&D findings.
