摘要

Greater use of muitispecies pastures can be a viable option for improving the sustainability and protein self-sufficiency in goat farming. A 3-year study was conducted to measure the forage yield, botanical composition and nutritive value of a muitispecies pasture that was established both on-station at INRA (FERLus-Patuchev) and on eight farms (REDCap network) under a large diversity of soil and climatic conditions and of pasture utilization (grazing, cutting or both). In autumn 2012, muitispecies seed mixtures containing 9 species were sown on 11 fields (19 hectares). The mixture was composed of 60% grass and 40% legumes. On the experimental farm, total annual dry matter (DM) yield from the ungrazed (exclusive cutting) plots was 10.0±2.3 t ha~(-1). Average crude protein (CP) content of forages was 17.8±2.8% DM. On farms, the specific diversity increased over the years, thanks to sown species and due to germination of adventitious plants. On average, the DM yield and CP content of the second cutforage were 3.1 ±1.8 t DM ha~(-1) and 14.1+2.9% DM, respectively. This study presents an initial step for designing muitispecies pastures for goat grazing.
