Consulting, in his paper 'Immunity and
Feed Effeciency -- A Complex
Conundrum', after looking at overall health
management and the whole question of
'what is immunity', Mr Edwards suggested
how nutrition could be boosted.
Feed additives useful in implementing
beneficial nutrition strategies included
mycotoxin binders, Mannan
Oligosaccharides (bacterial adsorbent/
immune system stimulant), yeast extract-
nucleotides, glutamic acid and inositol.
"Porcine plasma and organic trace
minerals (Se,Mn,Zn,Cu,Cr) and fish oil
(long chain Omega 3 fatty acids (DHA,
EPA)," Mr Edwards said.
"In light of pressure to reduce antibiotic
use in livestock production, greater emphasis
is being placed on utilising the animals
own natural defense mechanisms to
manage herd health."
Megan Edwards, also of ACE Livestock
Consulting stayed on the immunity/nutri-
tion track with her paper, 'Using Immuno-
nutrition to Improve Weaner Productivity'.
Her recent PhD research covered
nutritional strategies to limit the post
weaning growth check in young pigs.
Ms Edwards drew attention to, "the
magic of spray dried porcine plasma and
why nucleotides are conditionally essential
nutrients for weaner pigs".
Peter Williams, a partner in Feedworks
USA, delivered the final paper 'USA Elitox
research results from Virginia Diversified
Research Institute on DON/Vomitoxin).
He reported that current products
(similar range to Australia) were not over-
and Zearalenone (ZEN) challenges.
"Integrators/feed companies found
success using Elitox ETX-5 at .5kg/tonne
in grower /finisher pigs and 1kg/tonne in
sows where DON up to 2.5 ppm and ZEN
up to 400 ppb."
The final presentation of the day was
delivered by Doug Pearson from Feedworks
Australia. 'NIR On-Line -- commercial case
studies and how does this save money in a
feed mill?' was his topic.
"Online application allows NIR to
finally realise the truth of the information
it has been generating for the last few
decades," Mr Pearson stated.
In the Monogastric session, the keynote
speaker was chief nutritionist Jesper Pagh,
for the Danish DLG Group who gave an
insight into what could be regarded as one
of the most effective pork producing
organisations in the world.
"The Danish pig industry produces
about 27.4 m pigs pa (2.0m tonnes), 19
million slaughtered in cooperative-owned
processing facilities and 90% is exported.
"Live export of piglets (6.3 million,
mostly to Germany) is critical to industry
commercial viability. Growers make about
A$25 (30-100kgs) per pig but sows from
30 kg production make A$546.
"Live born piglets per litter at 14.2
pspa is way ahead of key competitors USA
(10.6), Canada and Brazil ( 11.2) but mor-
tality rates are higher at 14% (US 12%).
Key trends in Danish pig production
were Mr Pagh pointed out, "ongoing
conern around animal welfare and environ-
"Use of enzymes (phytase, xylanase),
reduced protein levels in feed; claw, feet
and shoulder lesions plus piglet mortality,
as well as antibiotic usage, were all issues
faced by the Danish pig industry," he said.
Rob Smits, Research Manager at
Rivalea Australia is in the final stages of
completing extensive research into the role
of Omega 3 fatty acids in sow reproduction.
In his paper, 'Nutrition and embryo
survival -- making the most of the sows'
potential', Mr Smits revealed that low levels
of fish oil (1%+-) had in experiments
conducted as part of his PhD work, been
shown to increase litter size.
In discussing recent interest in feed-
ing/energy levels of embryo survival he
stated that "outcomes were limited by
sample size of studies and that they may be
dependent on the source of energy and the
timing of high early pregnancy feed levels."
"Omega 3 PUFA's from fish oil was
shown to increase oocyte quality, embryo
survival and subsequent litter size born,
especially in mature parities," he said.
'There is money in improving fat
digestion-emulsifiers, for digestion and
research with Bredol to improve FCR over
the last 12 months,' was the title of Dr
David Cadogan's (Feedworks) paper.
"Bredol provides cost effective
improvements in energy digestibility in
young pig feeds, and the benefits of steam
pelleting on FCR are well supported," he
"The economic benefit of Bredol 683
in trials undertaken can be calculated
through the effects on feed costs, taking
into account the lower energy (10kg/T less
oil) and the higher moisture in the feeds."
On the question of using Bredol 683
or Bredol 688 Dr Cadogan pointed out
that '683' was the great all rounder for feed
(and water/liquid), processing/milling and
for nutritional benefit.
" Bredol 688 produces a greater protein
solubility/dispersion, and probably is the
better on intestinal fat digestion.
Dr Marnie Mellencamp, Director of
Immunology at Ralco Animal Health, gave
a paper, 'Regano when used as an antimi-
crobial/coccidiostat'. Containing oregano
essential oil, Regano promotes anti-micro-
bial, anti-fungal, and anti-oxidant activity
in livestock, and particularly pigs
Trials conducted by Ralco on Regano
in commercial pig units demonstrated
improved sow health and reproduction,
improved litter health, improved nursery
health (and performance) and improved
grow-finish health and performance," Dr
Regano was effective in combating
Coccidiosis where a sow trial in a North
Carolina unit resulted in more pigs
weaned, fewer dead pigs, fewer piglets with
scours, less drug treatments, as well as
increased feed intake.
"Using Regano was also cost effective
involving expenditure of US$5 per sow per
year," Dr Mellencamp said.
Doug Pearson (Feedworks) and Rob
Hewit from producer CHM Alliance out-
lined a commercial case study of savings
achieved by using the Feedlogic systems.
Mr Pearson gave delegates an overview
of the Feedlogic S-Series, a lower cost
option (than the M-Series) that uses exist-
ing feed lines and is suitable for applica-
tions where targeting by pen is not feasible.
Finally in the Monogastric session, Dr
Gary Partridge, Global Technical Services
Director, Danisco Animal Nutrition, gave
his paper 'Recent experiences with existing
and brand new Danisco products'.
On the topic of Danisco enzyme
solutions he outlined uses of xylanese in
more fibrous diets for pigs
"Phyzyme XP and Porzyme 9302 in
combination were shown in trials to
improve digestibility in pigs fed corn
DDGS," he stated.
He also introduced new pro biotic
product lines and spoke about trials using
the 'Direct Fed Microbial' (DFM) product
during late gestation and lactation.
In concluding Dr Partridge talked
about the new Danisco Genencor Division,
a joint venture with DuPont to develop
second generation cellulosic ethanol from
non feed plant material.
A lot of information was delivered
during The Coolum 2010 Nutrition
Workshop and apart from good science
there was a great social program, for
delegates and their families.
If you would like more information on
the papers Feedworks will provide a 'thumb
drive' (or CD) with more detail.

"Our target in simple terms to
meet global demand would be
to double food production and
more than double efficiency;
focusing on FCR and global
energy balance as a way to
achieve these goals"
