Eggs consumption in the UK is a success story with demand rising by 3-4% per year. However competition
between supermarkets has resulted in a highly competitive market meaning that egg producers
need to focus more than ever on cost of production per dozen.
LOHMANN BROWN wins on that score
through longer laying cycles and the
highest percentage of first quality eggs
of any brown layer in the market but, for
the supermarkets, that needs to be combined
with a clean audit sheet. Breeding
company LOHMANN TIERZUCHT has
been working on the key to that.
Through the combination of traditional
breeding methods and the introduction
of new technologies such as
genomics,
LOHMANN TIERZUCHT have
produced a range of incredibly productive
laying strains, commonly producing
over 12 times their own bodyweight in
egg mass through the laying cycle.
“When
we visit flocks in Holland and Germany it’s
not unusual to find flocks in production
up to 90 weeks old, still producing a high
percentage of first quality eggs” comments
Kenny Shaw, Managing Director of
LOHMANN GB.
“Selection by
LOHMANN
TIERZUCHT for more persistent production
– achieved through longer clutch
lengths has shown some birds in trials laying
clutches of more than 180 eggs! That’s
great for producers and makes the
LOHMANN
BROWN the most profitable bird
in the market but the issue can be how to
keep up with the birds nutritionally”.
Feed manufacturers have reacted to
the needs of the birds by increasing the
energy density and specification of diets.
However, energy isn’t the only requirement
for highly productive
LOHMANN
layers and it’s a real challenge balancing
all the dietary requirements of the birds.
As diets have become more energy dense,
the grain content of the rations has
increased leaving less room for other “traditional”
raw materials. One significant
impact of that is to reduce fibre levels
which can be as low as 2.5% in diets with
a high grain content.
Research by LOHMANN TIERZUCHT
now indicates that finding room in the
diet for indigestible fibre can have huge
benefits for LOHMANN birds. Robert
Pottgueter, Head Nutritionist at
LOHMANN
TIERZUCHT said “Even in the rearing
phase, fibre is beneficial and helps
in development of the gastro-intestinal
(GI) tract and feed intake capacity. In the
laying phase it is even more important in
aiding gut health, slowing down transit
of feed in the GI tract and improving nutrient
availability for the birds”.
LOHMANN GB has found this demonstrated
in a very practical sense
over the last 12 months. Kenny Shaw
said “LOHMANN birds are so productive
it’s sometimes difficult for them to meet
all their needs – production and maintenance
– through feed intake. For the
bird, production is the priority and, in
a few cases, we saw this result in some
feather loss with the LOHMANN BROWN.
We had a lot of discussions about this
with the breeding company and Robert
Pottgueter was convinced that the low
fibre levels in some modern layer diets
was detrimental for LOHMANN birds.
As
a result of this, and with the co-operation
of some of our long standing
LOHMANN
customers, we trialled the use of fibre levels
of 4.5-5.0% in layer diets. The results
were quite rapid and dramatic with birds
which had lost some feather showing regrowth
over a period of about 6 weeks
and birds fed on the high fibre diets from
16 weeks keeping absolutely perfect
feathering.
These results are great news
for producers who now get the benefit
of LOHMANN’s being able to maintain
longer laying cycles due to having shell
quality better than any other breed in the
market and without any indication of feather
loss from the birds.”
Robert Pottgueter added “Of course
good feed structure with some grist in and a balanced amino acid profile are
important – but these are normal factors.
It is fascinating that a low nutrition material
like fibre can have such a beneficial
impact on the birds and their production.
There are many ways to increase fibre
levels in diets, from proprietary lignocellulose
products that are available in the
market, to the use of more traditional
raw materials like barley, oats, sunflower
or rapeseed meal.
Increasing fibre levels
may require the addition of more oil to
the feed to maintain the energy level but
this is also a positive for the birds, reducing
the risk of fatty liver syndrome in
high producing layers and making the
feed more palatable by binding the fine
particles. We often find a reduction in
feed intake with high fibre diets due to
the slower transit of feed through the gut
and better utilisation of nutrients by the
bird, so it can be a no cost solution to improving
overall performance.”
“This is such a win for producers with
LOHMANN birds we want to make sure
everyone in the UK and Ireland is aware
of how to gain the benefits” said Kenny
Shaw.
LOHMANN GB will soon be starting
a tour of presentations to feed companies
and producer groups to go into
more detail on the benefits of high fibre
diets for
LOHMANN layers.
