As a consequence of the well described antagonism between reproduction (egg) and growth (meat) traits in chickens, there have been two distinct directions of modern genotypes: one towards egg production while the other direction has specialized on meat production traits. More than 40 million of one-day old male chicks of the layer lines are killed in Germany only, because of a low growth potential and less efficiency. This is however ethically quite problematic, and thus is a hot-discussion issue currently being debated in the European societies. Potential solutions to overcome this problem include approaches like in ovo sex determination and the use of dual purpose genotypes. In ovo sex determination is currently being intensively investigated, but no commercial use is available yet. Pilot studies have shown that dual purpose genotypes may produce meat and egg at acceptable levels. However, taking the structural changes in the production systems (e.g. classical cages systems are forbidden) into the account and considering the re-emerging health problems (e.g. parasite infections) in the new systems, it is essential to produce knowledge on health, nutrition, product quality of new and existing genotypes. Therefore INTEGHOF aims to compare a dual purpose genotype to classical egg or meat producing genotypes. Our aim at the FBN is to assess the ability of a dual purpose genotype to resist mixed nematode infections. We measure parameters of a wide spectrum to characterize resistance and resilience of three genotypes exposed to experimental nematode infections. Other partners are dealing with several other health, welfare, husbandry, product quality, nutrition issues.
