Ration and capability of different origins for organic broiler production
Project
Project code: 2806OE151
Contract period: 01.03.2008
- 31.12.2008
Budget: 44,145 Euro
Purpose of research: Applied research
Due to the regulation EG 2092/92 the feed used for organic chicken production has to be organic origin only. It is difficult to create feed mixtures with appropriate content of essential Amino Acids in relation to a given content of metabolizable energy. Experience with suited feed mixtures which were tested in practice are not available. In order to regulation EG 2092/92 it is necessary to use slow growing chicken only. The default in Germany is to take chicken from ISA-Hubbard, even though other genotypes are possible too. In this research project different genotypes will be tested. At the same time genotype-environmental interaction between different breeds and the feed mixtures will be checked. Two feeding trials with 1200 chicken in total will be carried out. The chicken of different genotypes (ISA-Hubbard, Sasso, Kabir) will be fed with two different feed mixtures up to an age of 81 days. The feeding regimes are different in (reduced) energy content (starter feed 12,0 MJ ME/kg vs 11,0 MJ ME/kg; finishing feed 12,4 MJ ME/kg vs 11,2 MJ ME/kg) along with a lower content of essential Amino Acids (AA) - at a constant ratio of amino acid:metabolizable energy (AA:ME). Due to the capability of chicken to level reduced feed energy by higher feed intake may result in an appropriate intake of essential Amino Acids and similar growth rate and carcass value. Both feed mixtures will be tested with all genotypes to clarify genotype-environmental interaction.
