Middle East will remain IUII
major importer I

Over a decade ago, the Middle East was
seen as the most interesting area in terms
of developments in the poultry produc-
tion and trade. Today, the poultry indus-
try is looking at it from a new point of
view. The policy to become self-sufficient
has been more than successful for some

countries, while others still depend on 12

imports.

Cockfighting promotes and
preserves native Thai chicken

In order to improve the bio-diversity and to pre
serve genetic resources, the Thai Native Chicken
Conservation and Development Association (TNC-
CDA) organised the first International Amateur
Cockfighting Competition. The associations' presi-
dent Dr Abhichai Ratanavaraha explains that this
competition also helps Thailand's economically dis-
tressed farmers. 25

Reproduction is a crucial problem
in ostrich breeding

One of tlie most important limiting factors in the
expansion of the ostrich industry is the low rate of
reproduction as compared to poultry. Reproduction
is a crucial problem in ostrich breeding. It is limit-
ing the economical turnover and thus has an influ-
ence on the further development of this "new ani-
mal" branch worldwide. 20

Plenty of choice when
looking for automatic
watering systems

Automatic watering systems are divided
into three main groups. Bell drinkers
were the first to appear, followed by
automatic cups. Nipples drinkers
became popular in the early eighties, but
were already in use for many years in
cage systems. Today, a poultry farmer
can choose from hundreds of different
types of drinkers. 36




The challenge of controlling
infectious coryza

Any effective coryza prevention strategy
must include effective measures to tackle
secondary complicating factors. Effective
antibiotics are available to control out-
breaks, but recovered birds remain carriers
of Haemophilus paragallinarum, and strict
biosecurity remains the best defence. 50
