The high crude protein concentration in leucaena suggests that energy supplements, which are readily fermented in the rumen, could be used to capture the excess rumen degradable protein and provide more microbial protein and metabolizable energy to the animal, further increasing liveweight gain or milk production. This approach has been tested in grazing cattle and also in cut-and-carry systems in Australia and Indonesia. In both systems, production (liveweight gain or milk production) increased with the addition of supplements containing large amounts of fermentable metabolizable energy. The substitution of the basal diet (leucaena or leucaena mixed with grass or crop residues) by the supplement also means that more animals can be carried in the system for a set amount or area of leucaena. The same principles would apply to any tree legume-based system. Energy supplements can come in many forms, viz. fermentable starch (cereal grains and cassava), sugars (molasses), pectins (soybean hulls and pulps) and fibre (rice bran, cassava bagasse), but they have not been compared for their efficacy nor for their economic benefit, if any, in these systems. | Publication Type: | Conference Publication | Conference Details: | ILC2018: International Leucaena Conference 2018, Brisbane, Australia, 1st - 3rd November, 2018 | Source of Publication: | Tropical Grasslands-Forrajes Tropicales, 7(2), p. 182-188 | Publisher: | International Center for Tropical Agriculture | Place of Publication: | Colombia | ISSN: | 2346-3775 | Fields of Research (FoR) 2020: | 300303 Animal nutrition | Socio-Economic Objective (SEO) 2020: | 100401 Beef cattle | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication |
