• Abstract

  The objective of this visiting researcher proposal is to enable collaboration between researchers and research groups in the development of teaching, research and extension projects, in this occasion between Dr. James W. Oltjen and the research group of the São Paulo Agribusiness Technology Agency (APTA - Colina/SP) and UNESP, Campus Jaboticabal. The grant will consolidate the relationshi…

  Nutritional plans and beef cattle growth curve: meta-analysis and project prospecting, AV.EXT

• Abstract

  The aim of this study was to evaluate the strategies of supply of rehydrated corn grain silage with different processes in the performance and metabolism of Nellore cattle. Three experiments will be performed. In the first experiment, the in situ degradability, fermentation profile and aerobic stability of the silage processed in a hammer mill with different particle sizes were evaluated.…

  Rehydration and ensilage of corn grains with different grain sizes and inclusion in the diet for beef cattle, AP.R

• Abstract

  Corn is the primary grain used in feedlot diets. In Brazil kind of flint corn is the predominant presenting high vitreousness, which reduces its digestibility. The processing of corn for ensiling high-moisture corn increases its digestibility by promoting proteolysis of the protein matrix. New techniques such as rehydration of dried corn for later ensilage have been practiced, but there a…

• Abstract

  The aim of this study is to evaluate the aerobic stability (AS) of reconstituted corn grain silages (RCS) using different inoculants and of supplements containing RCS for beef cattle in finishing phase on pasture with high supplementation as well as the effects of its consumption on the animals. Experiment 1 (Exp. 1.) will consist of evaluating the RCS without and with the use of Lactobac…

• Abstract

  The present study aims the evaluation of effect of corn processing and inclusion of lasalocid sodium on the termination of Nellore bovines in grazing of Brachiaria brizantha cv. Marandu, in system of high supplementation in dry season, on performance, carcass characteristics and ruminal parameters. The experiment will be carried out at the research unit of Polo Regional de Desenvolvimento…

  Evaluation of corn processing and lasalocid Nellore cattle finishing in high dry supplementation system, BP.MS

• Abstract

  Objective is to evaluate nutritional and management strategies that allowincrease nitrogen utilization efficiency and consequently raise the performance supplemented cattle in pastures. Two experiments will be conducted in APTA, Polo High Mogiana, Hill-SP. The treatments consist of two factors in factorial 2 x 2, as follows: Exp1 (dry phase): non-protein nitrogen source (urea and urea enc…

• Abstract

  Barley is one of the primary sources of energy used to feed beef cattle in Australia. The diversity in test weight and screenings of barley received by Australian feedlots often raises questions of the nutritive value of different grades of barley. The study aims to investigate the rumen degradability, in vitro volatile fatty acids production and starch content of different grades of barl…

• Abstract

  The objective is to collaborate the project that has as main proposal to determine the effect on the performance of cattle fed a diet with a high crude protein (CP) during of metabolizable energy (ME) restriction and what the compensatory growth response (in body and skeletal weight) When these animals come to have access ad libitum to the diet with high CP and ME. Two genotype, fifteen B…
