| The QLIF project has targeted a variety of issues to make organic animal production (dairy cattle, pig, poultry) more safe, develop alternative methods to promote animal health and improve product quality. This workshop will discuss these aims as well as the QLIF achievements to date. It will also address our way of assessing the quality of our organic farms. We ask the question what the advantages are of doing this by looking at the output of a farm, such as yield, animal welfare and environmental issues. Alternatively, we also want to know what benefits there are in looking at how the farm is organised, via input factors such as housing design, nutrition, management quality. Two invited speakers will state their preference. Legislation, certification and... |

| The main dietary challenge for poultry producers is ensuring that feed fulfills the nutrient requirements of poultry, in particular with regards to protein and the correct amino acid profile. This is a particular challenge for organic poultry producers as the use of synthetic amino acids is not allowed. There has been a derogation from the EU Organic Regulatory Board to allow organic pig and poultry producers to include up to 5% non-organic feed within their rations to assist in meeting the nutritional requirements of the animals. This derogation was due to finish at the end of December 2014 but has now been extended to 31 December 2017 when it will become compulsory under EU Regulations (EC) no 889/2008 to provide all organic livestock with feed derived... |

| Free range and organic systems expose the laying hen more to unexpected events and adverse climatic conditions than barn and cage systems. In France, The Netherlands and Switzerland the requirements for a hen suitable to produce in free range and organic systems were discussed with farmers. The farmers preferred for these systems a more ‘robust’ hen, more specifically defined as a heavier hen with good eating capacity. Benchmarking of flocks in a web-based management program in The Netherlands from layer flocks finished in 2008 – 2013 indicated that in earlier years indeed mortality among organic and to a lesser extent free range hens was higher than among barn or cage hens. Feed conversion (kg feed/kg eggs) is higher, but the gap is closing.... |
