A full house at the Poultry World
event at VIV MEA in Abu Dhabi. The seminar, focusing on poultry health and
nutrition for the Middle East attracted many visitors from Europe and the
Middle East.
The VIV MEA is currently being held
in Abu Dhabi. It is the second edition of this event. It is co-located with the
Global Forum for Innovations in Agriculture (GFIA). On the first day, VIV MEA
attracted 2,652 visitors and 368 exhibitors. People came from 46 different
countries. Compared to the previous edition in 2016, this is an increase of 33
in the number of exhibitors. This year, a significantly higher number of people
came from Canada, Singapore, Denmark and Austria. On the second day of this
well attended event, multimedia brand Poultry World hosted a seminar on poultry
health and nutrition. The room was full and lively discussions took place.
Think
outside the soy box
Mohamad Farran, PhD from the
American University of Beirut (AUB) kicked off the meeting with an excellent
presentation about diet formulation and the quest for new protein sources in
poultry diets. Mr Farran said: “We use a lot of soybean meal in poultry diets
and this is costly. In addition, the variance in quality and the availability can
be a problem.” In his presentation he explained that for the Middle East
region, some other protein crops might be interesting to look at. He addressed
that these should fall in the category of ‘rainfall’ crops and not summer
crops, as the latter is heavily dependent on irrigation.
Mr Farran touched on 4 different
alternative protein crops:
- Common Vetch,
- Bitter Vetch,
- Faba beans
- Safflower
Some of these crops contain
anti-nutritional factors, so treatment of the seed is sometimes needed. But for
Faba beans for example, tannin-free varieties are available, so no treatment is
needed here. Trials at the American University of Beirut in both layers and
broilers have showed excellent results in zootechnical performance or egg yolk
colour for example (for safflower). Next to the nutritional value, Mr Farran
explained the economical side of using other ingredients over soybean meal.
“With some of the current prices in Lebanon, we see that many of the
alternative crops are cheaper than soy. If we include Safflower in broiler and
layer diets at a 25% inclusion rate, in theory we can save US$ 125,000 million
on feed costs in the whole MENA region.” Mr Farran said, we have to think
outside the box and look for different poultry sources. These crops can be
grown (or are already grow) in many countries in the MENA region.
Getting
diseases under control in the Middle East
Hannes Meyns, Veterinary poultry
consultant at Vetworks in Belgium
updated the audience on the common (endemic) disease in the Middle East and
effective ways on how to better control them. “Low pathogenic Avian Influenza (LPAI) is
the main one in the category respiratory diseases. It is an ongoing challenge
for most countries. At the same time, the Middle East is a crossroads for many
bird migration routes. Migrating birds are a risk as they can spread the virus
to commercial poultry farms.” Mr Meyns explained that Avian Influenza can be
eradicated best with: High biosecurity, all-in and all-out system (if possible,
although not common in the Middle East), diagnostics and surveillance and
educating staff in AI control strategies. “The problem is that the Middle East
faces an endemic spread of LPAI H9N2 and vaccination is expensive and doesn’t
give 100% protection or control.” Newcastle Disease is also
endemic in the Middle East. “An optimal protection against this disease can be
accomplished by making sure that vaccination reactions are reduced (e.g. use
enterotropic vaccines in younger birds, synchronise vaccinations on multi-age
farms and build up protection against the disease gradually (use different
methods / products in different age groups in broilers for example). Mr Meyns
also touched on infectious bronchitis, and addressed
that in particular IB variant 2 is a difficult strain to control, but the first
homologous vaccines are now available.
Building
immunity from the start
The third and last speaker of the
event was Walid Al Saleh DVM, Avian technical and marketing manager at Boehringer Ingelheim Animal Health.
Mr Al Saleh kicked off his presentation by explaining how the immune function
works and which cells come into action, when and where.
There are 4 different defense
strategies:
- The nonspecific one physical barriers like the skin)
- The passive immunity (MDA)
- The innate immunity (monocytes, macrophage, natural killer cells)
- The adaptive immunity (lymphocytes (B,T & NK).
How the immunity works is key in
making the right vaccines against different kinds of viruses. Mr Al Saleh
explained: “Infectious bursal disease (IBD, Gumboro) is an acute,
highly contagious viral infection in chickens, manifested by inflammation and
subsequent atrophy of the bursa of Fabricius. Vaccination against this disease
is very important and the main question is: how to catch all the birds with 1
vaccination?” There are different types of vaccines to control the disease. A
vector vaccine by Boehringer Ingelheim (Vaxxite) is aimed to accelerate
maturation of chicken embryo immune responses. Trials with this vector vaccine
showed good results regarding the bursa lesions (histological score). Trials in
layer pullets compared the Vaxxitek IBD vaccine and 2 live
vaccines. “We showed that the bursa / body weight ratio at 70 days of age was
best in the Vaxxitek group. All in all, this results in better profitability
and performance for poultry flocks.”
