Esta metodolog\u00eda es novedosa y trata de estudiar las variaciones nutricionales de las pasturas como consecuencia de los cambios morfol\u00f3gicos que experimentan las plantas mientras rebrotan luego de un pastoreo de animales. Espec\u00edficamente esta recopilaci\u00f3n de protocolos, planillas y datos colectados muestran c\u00f3mo aplicar esta metodolog\u00eda en Kikuyo, una especie de gram\u00ednea tropical. El ejemplo fue realizado en Sydney (Australia) pero la generalidad de los conceptos puede aplicarse a cualquier especie y lugar. Kikuyu grass is a C4 grass adapted to both the tropics and temperate climates. It is fast growing and produces dry matter of moderate quality; generally higher quality than most C4 pastures. However, Kikuyu\u2019s leaves lose quality very rapidly if not consumed at the right time, with the window of opportunity being generally smaller than for temperate grasses. In temperate grasses, a decrease in fibre digestibility (NDFD) of leaf blade tissue was reported as mainly responsible for declines of forage digestibility (DMD) during vegetative regrowth. Further, studies in tropical and temperate species showed that NDFD and DMD declined not only with the thermal time of leaf age, but also with the length of successive leaves. These morphogenetic and nutritive value relationships are poorly described for kikuyu plants, and it is imperative to increase our understanding and prediction of rapid changes in the nutritive value of Kikuyu tillers and leaves, and the pasture overall."],"dc:format":["application\/octet-stream","application\/msword","application\/vnd.openxmlformats-officedocument.wordprocessingml.document"],"dc:language":["eng"],"dc:type":"dataset","dc:rights":["info:eu-repo\/semantics\/openAccess","https:\/\/creativecommons.org\/licenses\/by-nc-sa\/2.5\/ar\/"],"dc:relation":["info:eu-repo\/grantAgreement\/University Of Sidney.
