3...The eight-year project to develop
the ISA WARREN represented a new
dimension in breeding, introducing new
features such as ethology - the
science of animal behavioiur - to better
understand the social relationships
between birds, the real key to improving
liveability. The choice of 'Warren' is
taken from the proud heritage of the ISA
breeds, where the name is associated
with reliabiliity and high performance.
The ISA WARREN has been bred as a
tough, resilient layer which is easy to
manage and retains good feather all
through lay - an important attribute in
modern free range production.
Good early egg size helps meet the
supermarket demand for larger free
range eggs, with a controlled increase
in egg weight after 50 weeks. |
The ISABROWN is raising customers’
expectations... achieving higher income
through it's well recognised low feed
conversion and outstanding egg numbers,
while also proving easier to manage.
The breed is benefiting from a new ‘PQB’
approach to selection on which ISA
geneticists started focusing in 1997.
3...Persistency, selecting birds at pedigree
level to 85 weeks so that on commercial
units production stays high for up to five
weeks longer.
3...Quality reflected in stronger shells,
more uniform colour and more control of
egg weight.
3...Behavioural improvements resulting
in liveability and performance in intensive
and alternative systems, where the low
level of floor eggs is a significant
advantage.
Add to this the breed’s traditional
advantages in egg numbers, egg mass
and feed conversion, and you'll find
ISABROWN the top performer.

3...The Shaver Brown is long renowned
for its reliability. It has benefited from
continued ISA research investment,
focusing on traits which make it versatile.
The Shaver layer is readily able to achieve
consistently high performance in both
intensive and alternative systems, even in
the more challenging environments.
