Organic poultry production: an
alternative
1. Introduction

Land-related production
Low density

Environmental equilibration


Genetic material in poultry production nowadays

100 % use of highly productive hybrids

Hybrids are produced by colossal companies and are
“trade secrets”
Structure of producing and trading of hybrids
1
Hybrids developing companies
Produce paternal and maternal lines for
egg and meat production after crossings
2
Reproductive companies
Hatcheries
Crossing of maternal and paternal lines
and production of hybrids
3
Producers
Rearing of hybrids and production of
eggs or poultry meat
http://bioagro.aua.gr
Hybrids
Products of crossings between breeds and lines
with desirable attributes
http://bioagro.aua.gr
A secret well kept…
 Reproductive
companies cannot produce
paternal or maternal lines because these are
also hybrids
 Hybrids’
reproduction ends to diversity and
decrease in the desirable attributes , due to
gene segregation
http://bioagro.aua.gr
Absolute centralization…
Hybrids’ producing companies nowadays
Maternal company
Reproductive companies
Erich Wesjohann Group
Hi-Line, Lohmann , Ross, Arbor Acres, L.I.R.,

Advantages and disadvantages
 Advantages




Fast movement of the genetic progress to the farmer
High productivity
Constant improvement of desirable attributes
Disadvantages



The farmer always depends on the maternal company for
the acquirement of poultry hybrids
Decrease of genetic diversity
Global genetic material is the same
http://bioagro.aua.gr
The target
 Choosing
the appropriate genetic material
(hybrid) so as to have the best result in
accordance with the production system
(rearing practices, diets, hygiene issues)
http://bioagro.aua.gr
Conclusions

Poultry meat and egg production uses exclusively
hybrids of various types and colours, different for
each production sector

Medium and slow growing broilers are more
suitable for organic poultry meat production

The same egg-laying hybrids used in conventional
production are also used for organic hens
