Do you give your dairy cows palm kernel
expeller (PKE) animal feed?
Our latest case study shows it can deliver
real benefits in terms of sustainability and profitability.

Astrid Duque, DAABON UK Director
From a splash of milk in a cup of tea to freshly
buttered bread and creamy cheeses, dairy plays an integral role in
our
day-to-day dietary requirements and wouldn’t exist without the
millions of
domestic cattle milked every day by the dairy industry.
Demand for this essential commodity has caused the
dairy industry to experience an exponential growth over recent
decades. This
has led to concerns about its environmental impact, and it is
currently under
pressure to improve sustainability credentials and reduce its carbon
footprint.
For dairy farmers, this means examining their
current supply chain to see what changes can be made – and this
includes
switching to sustainable feed.
High-producing dairy cows, for example, will eat a
remarkable 50 - 55kgs fresh weight or 15 - 20 kgs of dry matter (or
3% of their
bodyweight) per day. Sourcing a sustainable yet effective feed is
essential if
the industry is to become more environmentally friendly whilst
continuing to
fulfil current demand levels without compromising the quality of the
end
product.
Happy
Cows = Happy Dairy Farmers
A
well-maintained cow will deliver good-quality results. Farmers can
ensure that
milk of a suitable standard is being produced by going straight to
the source
and making sure that their cows are healthy and happy.
We all know PKE is widely use in the ruminant
sector, however DAABON headquarters’ NPD department led by Dr. Maria
del Pilar
Noriega is actively working to identify the value added of the
existent feed
materials and other potential blends.
“Our aim was to examine the milk’s butterfat
content, as one of the primary markers of a cow’s health and overall
wellness.
A cow requires high-quality, well-balanced nutrition to produce milk
and be
profitable,” says Dr Noriega.
DAABON
UK Part of the solution
DAABON is the main source of organic and
sustainable PKE in the UK. We are FEMAS and RSPO IP accredited –
ensuring full
traceability of this feed material all the way back to the growing
plantations
in Santa Marta, Colombia.
As part of our research, in 2021 we partnered with Barrington
Organic Partnership Ltd and Daykin Partnership to carry out an
experiment using
DAABON PKE as
a straight feed alongside the compound option in ratio formulation.
“The aim of the study was to prove the
hidden benefits of DAABON’s PKE, offering insight into how this
commodity is
practically and financially a better choice for dairy farmers
looking to
demonstrate their commitment to sustainability. The results were
mind blowing,” says Astrid Duque, Managing Director
of DAABON UK.
Barrington Farm – PKE Animal Feed
Barrington Organic Partnership Ltd founder, Andy
King, is well known in the organic feed space for his nutritional
and
formulation expertise. Barrington has been using DAABON’s PKE in
their 250
year-round calving heard since May 2021.
Barrington Farm was initially on a white-water contract regarding
butterfat,
but in May 2020 moved to a contract that not only had a minimum
specification
for fat, but also was paid more for higher fat levels.
Whilst the farm produced an average annual butterfat level of 4%,
there were
several months in the summer where fat levels were low and sometimes
near the
milk contract minimum.
The farm’s recent butterfat levels for the summer
months and annual averages are seen below, where levels drop off in
May about
six weeks after turnout. Despite heavy buffer feeding with silage
from July,
the levels do not usually rise until September.

Barrington
Farm – Results
The daily
butterfat levels over the summer period for the last two years are
seen below.
These are shown in relation to the contract target and contract
minimum from
May to July.
“My approach is
always to look at the wellbeing
of the cow and the farmer reward, understandably PKE had a role
to play in the
dairy nutritional plan, however based on my studies, I
anticipated this raw
material was underestimated and that perhaps it required an
approach on to farm
where farmers are not necessarily used to it” says
Andy King.
“The purpose of
the experiment was to
look into a different use of PKE and to compare against
historical data, the
results have been encouraging” says King.
In 2020 cows
were turned out in early April and it was decided to feed 1.5kg of
lucerne
pellets added to the outside blend of 2kg 16% protein meal and
silage from
early May. When this failed to stop the butterfat decline 400g / day
of organic
protected fat (no longer allowed) was fed from late June. Whilst
this did
increase butterfat above the minimum level, overall fat levels were
still low.
In 2021 cows
were turned out again in early April but depleted silage stocks
ensured only
5kg of round bale silage was fed as a forage buffer. A maximum of
2.5 kg was
fed as a concentrate with 1kg coming from straight palm kernel and
1.5kg coming
from the 16% protein blend. The diet was fed from 2 weeks after
turnout (mid-April).
Results
In 2020 milk
fat declined from early May and stayed at the low level until late
July. In
2021 there was no milk fat decline until late May. Butterfat levels
in 2021
remained significantly higher than in 2020. This was especially
evident in the
trough of June and July.

“I believe a
combination of practical
rationing and feed modelling is needed to get the best from the
product and to
understand its limitations. Ultimately the ultra-mix rationing
programme used
in conjunction with nutritional experience has delivered these
results and met
farmer needs,”
says King.
Adds King: “This
year’s approach has
been to look at its use as a straight on three other farms.
These have had
broadly the same requirements concerning milk quality and have
demonstrated
similar results.”
