[more ▼] Walloon cereal production currently provides only 8 % of Belgian food chains, mainly because of low prices paid for food varieties, less favourable climate conditions and scattered plots of land. Key opportunities for non food uses are considered in a sustainable development perspective. But this can only be achieved through an exhaustive comparison of environmental and socio-economic impacts of existing and potential cereal chains. Biofuels – particularly bioethanol – are the predominant energy chains and are more and more developing in Belgium. Bioethanol industry has strongly developed since 2008 undoubtedly linked to European political support measures. The project “Alternatives for Cereals – ALT-4-CER” aims to define and to evaluate alternative scenarios for food and non food uses of cereal resources in Wallonia with the support of involved stakeholders.

[more ▼] Artificial pastures are used to increase carrying capacity in the wet tropics by supplying higher quality forage (energy and protein) to the animals all year long. Sowing pastures is labour-intensive so to be profitable all other possible growth limiting factors, especially minerals, should be alleviated. We studied nutrients intake (energy, protein and minerals) in cattle grazing Urochloa sp. pastures in Western DRC. Three Urochloa ruziziensis and 3 U. decumbens pastures in Kolo-Fuma (Bas-Congo, DRC) were studied. Three Ndama steers and 3 cows grazing each pasture consecutively during the short rainy and dry seasons were followed by handplucking and samples were analysed for energy, crude protein and ash to calculate energy value (fodder units, FU) and digestible crude protein content (DCP) of the diets. NIRS was used on faeces to determine dry matter (DM) intake and ICP-AES to determine mineral content of the diets. Intake levels reached 66 ± 4.3 g kg-1LW0.75, nutritive value of forage was 0.701 ± 0.036 FU and 4.78 ± 1.04 % DCP, allowing daily weight gains > 550 g for steers and > 350 g for cows. P, Ca, Mg, K, Mn & Fe were provided above requirements by the pasture. Na, Cu and Zn were deficient, especially during the short dry season for Cu and Zn. U. ruziziensis pastures tended to provide more minerals, especially during the rainy season. A mineral supplement providing Na, Cu and Zn is required to reach the daily weight gains allowed by energy and protein supplies. The supplement could reasonably be similar for U. decumbens and U. ruziziensis pastures, but the dry season formula should provide more Cu and Zn than the rainy season formula [less ▲] Detailed reference viewed: 41 (13 ULg) Ingestibilité et valeur alimentaire des foins issus de prairies de haute valeur biologique; ; et al Article for general public (2009) Detailed reference viewed: 20 (3 ULg)Ingestibilité et valeur alimentaire des foins issus de prairies de haute valeur biologique.; ; Stilmant, Didier et alin XVes Rencontres recherches ruminants (2008) Detailed reference viewed: 35 (6 ULg)Evolution d'une prairie de fauche sub-montagnarde soumise à un fauchage très tardif et à des essais de fertilisation; ; Rouxhet, Serge et alin Fourrages (2008), 195 Dans le cadre des mesures agri-environnementales (ancienne législation), un essai fauche très tardive a été mis en place durant huit années à Elsenborn (Ardenne belge, 620 m d'altitude), de 1997 à 2004 ... [more ▼] Dans le cadre des mesures agri-environnementales (ancienne législation), un essai fauche très tardive a été mis en place durant huit années à Elsenborn (Ardenne belge, 620 m d'altitude), de 1997 à 2004. L’objectif de cet essai est de quantifier les changements de végétation suite à l’apport d’engrais de ferme, tout en tenant compte des rendements et de la valeur alimentaire du foin récolté tardivement.
