Dry matter production, nutritive value and efficiency of nutrient utilization of a complementary forage rotation compared to a grass pasture system

摘要: In pasture-based dairy farming, new sustainable systems that involve the annual dry matter (DM) production of grazed and conserved forage beyond potential pasture alone are being sought. The objective this experiment conducted in Australia was to compare a complementary rotation (CFR) for conservation grazing, comprising an sequence three crops, namely maize (Zea mays L), rape (Brassica napus L) legume (Persian clover, Trifolium repesinatum L or maple pea, Pisum sativum with [kikuyu grass (Pennisetum clandestinum) over-sown short-rotation ryegrass (Lolium multiflorum L)] as control treatment. complete randomized block design four replicates (� 0AE7 ha each). Annual dry-matter yield over 3 years averaged >42 t )1 year CFR treatment >17 high DM resulted from >27 harvested silage >15 utilized by grazing legumes. Total input nitrogen (N) water were similar both treatments, resulting higher Nand water-use efficiency treatment, which more than twice Overall, nutritive value slightly mean implications these results highly productive system based on conjunction use is achievable. Such could increase total supply feed resources grown onfarm key such N water.
