2 Dairy production in Brittany dairy farms (50 % total farms) 4,9 billion liters collected 22 % of french production l / farm 51 cows / farm l / cow 57 % of specialised dairy farms 21 % milk + cattle 13% milk + pig or poultry 9 % milk + cattle + pig or poultry Source : Agreste RGA 2010 Chambers of agriculture of Brittany Average farm 82 ha AA 56 ha forage area l sold 56 cows 7981 kg milk / cow 1109 kg conc / cow 3,8 T DM conserved forages / cow Source : Conseil Elevage Nord-Pas-de-Calais 2

3 Diversity of DAIRYMAN development plans More feed autonomy Less energy consuption Less workload and hardness More feed autonomy Adaptation of the grassland species Less inputs (mineral fertilisers, pesticides, concentrates) Less mineral fertilisers and pesticides Less energy consumption (simple soil cultivation) Less workload More feed autonomy Less inputs Less workload (week-ends) More milk Better milk production per cow thanks to maize Maintain low inputs (mineral fertilisers and concentrates) System with more grass More feed autonomy Less inputs (agroenvironmental measure SFEI) More milk Better milk production per cow thanks to maize and higher grass yields Less mineral fertilisers Conversion to organic farming Better work organisation over the year Better grasslands productivity and quality Less inputs (mineral fertilisers and concentrates) More milk Stop young bulls production Better productivity of grasslands and dairy cows Conversion to organic farming Nord-Pas-de-Calais 3

7 Farmers objectives A better productivity of herd and land but respectful of environment and economically profitable Economy Better income - Stop young bullls production to produce more milk - More milk per cow Social Balance work / family life - Facilitate work (animal restraint, office, feeding table for cows) - Contractor for fields work Farmers objectives Environment Better land productivity - Rotation with grass over all the farm area - Optimisation manure management - Less pesticides Nord-Pas-de-Calais 7

13 Project assessment Project objectives Reached Not reached ECONOMY ENVIRONMENT TRAVAIL Stop young bulls Produce more milk Less purchased concentrates Rotations with grassland, Grasslands for harvest with legumes Less fertilisation Better grassland productivity Adjustments to facilitate work Contractor for field work Plus de lait / VL Better income (context : increase of inputs prices) More grass in dairy cows diet (difficult grazing season in 2012/2013) Nord-Pas-de-Calais 13

14 In the future After 2013 : Stop definitively young bulls production Produce the milk proposed by the dairy cooperative (in particular volume A of august, september, october) Max liters Jump on opportunities to have more land Which economical and environmental impacts? Nord-Pas-de-Calais 14
