Objetivou-se avaliar o balanço energético de cordeiros em terminação alimentados com dietas formuladas de acordo com o National Research Council ? NRC (1985) e o NRC (2007). Foram utilizados dezenove cordeiros, machos, com quatro meses de idade e peso vivo médio de 17,7 kg. Os tratamentos consistiram de dietas formuladas conforme o NRC (1985) (NRC85) e o NRC (2007) considerando-se os consumos de 20%, 40% e 60% de proteína não degradável no rúmen (PNDR), aqui denominadas NRC07/20, NRC07/40 e NRC07/60, respectivamente. O NRC (2007) sugere um consumo de nutrientes digestíveis totais (NDT) para cordeiros em crescimento da ordem de 43,35 gramas por unidade de tamanho metabólico (g/UTM), sendo todos valores médios obtidos superiores (67,79 g/UTM). Verificaram-se menores balanços de energia para a dieta NRC07/60. Esse menor balanço observado foi afetado pelo menor aporte energético (NDT) fornecido na dieta, sendo influenciado pelos maiores valores dos constituintes fibrosos e da lignina. A dieta NRC07/60 promove uma menor eficiência de uso da energia dietética. Energy balance of lambs feedlot fed diets formulated according to NRC (1985) and NRC (2007). Abstract: The study aimed to evaluate the energy balance of lambs feedlot fed diets formulated to according the National Research Council - NRC (1985) and NRC (2007). Nineteen male lambs with four months old, with average body weight of 17.7 kg. The treatments consisted of diets formulated according to NRC (1985) (NRC85) and NRC (2007) considering 20%, 40% and 60% of undegradable intake protein (UIP), called here NRC07/20, NRC07/40 and NRC07/60, respectively. The NRC (2007) suggests an intake of total digestible nutrients (TDN) for lambs in growth of about 43.35 grams per unit metabolic size (g/UMS), all values obtained in this study higher (67.79 g/UMS). There were smaller energy balances for the diet NRC07/60. This balance was less affected by lower energy intake (TDN) supplied in the diet, being influenced by high values of fiber constituents and lignin. The diet NRC07/60 promotes a lower utilization efficiency of dietary energy.

The primary goal of this study was to evaluate the phosphorus uptake and use efficiency in Brazilian soybean cultivars, besides root morphology and architecture characteristics related to phosphorus uptake, carrying out two greenhouse experiments. The experiment 1 was completely randomised, with 56 treatments (soybean cultivars) and 3 replicates. Experiment 2 was completely randomised design with three replicates, and the ten cultivars (greater and lower efficiency) were selected for this assay according to their ability to absorb phosphorus less available determined in experiment 1. The study was carried out at Center of Nuclear Energy in Agriculture, University of São Paulo, Brazil, between February 2011 and August 2012. The isotopic dilution technique was used in the first experiment to assess the phosphorus availability in the soil and to determine the ability of plants to access labile phosphorus by measuring the specific activity of plants grown in soil labeled with radioactive phosphorus. Nine cultivars showed greater phosphorus uptake and used efficiency. The second experiment evaluated the root morphology and architecture. The cultivars with greater uptake efficiency have root morphology and architecture characteristics that favour acquisition of phosphorus from soil compartments that are inaccessible to other cultivars. Phosphorus uptake by plants was not affected by soybean seeds phosphorus content. Identification of these cultivars is very important because it could enable soybean farming in low fertility soils, reducing fertiliser dependence.
