Última Frequencies and intensities of defoliation in Aruana guineagrass swards: morphogenetic and structural characteristics R. Bras. Zootec. Zanini,Guilherme Doneda; Santos,Gabriela Trevisan; Sbrissia,André Fischer. The objective of this study was to evaluate the morphogenetic and structural characteristics of Aruana guineagrass pastures (Panicum maximum cv. Aruana) subjected to rotational stocking by sheep. The treatments corresponded to grazing when swards reached 95 or 98% of interception of incident light (LI) until post-grazing heights of 10 and 15cm and were allocated to experimental units (plots of 196 m²), according to a 2 × 2 factorial arrangement in a completely randomized design, with three replications, from January to May 2009. The morphogenetic assessments included: leaf appearance and elongation rates (LAR and LER), phyllochron (PHY) and leaf life span (LLS). Structural evaluations assessed the number of green leaves (NGL), dead leaves (NDL) and...

Bras. Zootec. Zanini,Guilherme Doneda; Santos,Gabriela Trevisan; Sbrissia,André Fischer. The objective of this study was to assess the accumulation and morphological composition of forage in Aruana Guineagrass (Panicum maximum cv. Aruana) swards subjected to intermittent stocking with sheep. Experimental treatments when grazing was introduced included low (95%) and high (98%) incident light interception and low (10 cm)- and high (15 cm)-residue height and were allocated to experimental units (196 m² fenced areas) in a completely randomized 2 × 2 factorial arrangement with three replicates. Treatments were imposed between January and May 2009. More frequent grazing cycles (95% light interception) resulted in better control of stem elongation, lower proportion of dead plant material and invasive plants, and higher proportions of leaf blades in...

O objetivo deste estudo foi determinar a participação relativa de colmo na estrutura vertical de pastos de capim Aruana e azevém anual submetidos a estratégias de pastejo intermitente por ovinos. Os tratamentos para o capim Aruana corresponderam a pastejos realizados quando os pastos atingiam 95 e 98% de interceptação da luz incidente (IL) até as alturas pós-pastejo de 10 e 15cm. Para o azevém anual, os tratamentos corresponderam a pastejos realizados quando os pastos atingiam 15 e 25cm de altura pré-pastejo até as alturas pós-pastejo de 4 e 8cm. O delineamento experimental utilizado para as duas espécies foi inteiramente casualizado, em arranjo fatorial 2x2, com três repetições. Para quantificação da massa de colmo na estrutura vertical dos pastos, foram...

ABSTRACT: Italian ryegrass (Lolium multiflorum Lam) is one of the most cultivated temperate annual forage crop around the world. Despite that, there is little information about the process of stem elongation during its vegetative growth. This information would be useful for grazing management purposes. Thus, the aim of this study was to assess the herbage accumulation and stem elongation rates in annual ryegrass pastures submitted to intermittent stocking. The experimental design used was a completely randomized 2x2 factorial with three replications. The treatments were defined by the combination of two pre-grazing heights (15 and 25cm) associated with two post-grazing heights (4 and 8cm). The herbage accumulation rates were higher in pastures with 25cm...
