1. Grazing height targets for Alexandergrass pastures under continuous stocking in integrated crop-livestock system
RESUMO: O objetivo deste trabalho foi identificar alturas de manejo para pastos de papuã sob lotação contínua em sistemas de integração lavoura-pecuária (ILP). Para tanto, doze pastos foram cultivados em uma área de ILP e mantidos em 10, 20, 30 ou 40 cm por meio de lotação contínua com caprinos. As seguintes variáveis foram analisadas: massa; ta

3. Evaluation of blood metabolites in dairy cows grazing under two pasture allowances and supplemented with corn silage under restricted grazing conditions
ABSTRACT This study was conducted to evaluate the influence of management tools - daily pasture allowance and corn silage supplementation - during periods of forage shortage on the metabolism of dairy cows grazing low-mass pasture in temperate regions. Forty lactating Holstein cows were used during an experimental period of seventy days (April 15 to June 23,

4. Temporal profiles of vegetation indices for characterizing grazing intensity on natural grasslands in Pampa biome
ABSTRACT The Pampa biome is an important ecosystem in Brazil that is highly relevant to livestock production. The objective of this study was to analyze the potential use of vegetation indices to discriminate grazing intensities on natural grasslands in the Pampa biome. Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation In

5. Caracterização da vegetação, desempenho e seletividade de ovinos em caatinga raleada sob lotação contínua, Serra Talhada-PE.
A vegetação da Caatinga é um importante recurso forrageiro para o rebanho da região semiárida brasileira. Objetivou-se caracterizar a vegetação e o desempenho animal, bem como a seletividade de ovinos, ao longo do ano, em Caatinga raleada, no município de Serra Talhada-PE. Para tal, a pesquisa consistiu em levantamento de dados da vegetação e dos o

6. ESTUDO DA RECRIA DE NOVILHAS DE CORTE EM PASTAGENS CULTIVADAS DE VERÃO / STUDY OF BEEF HEIFERS REARING ON WARM-SEASON PASTURES
Heifers rearing is a determinant step of efficiency in beef cattle production systems on pastures. Several experiments have tested alternative uses for tropical grasses to heifers rearing. In order to summarize results and making not visible relationships evident in these individual experiments an analysis was performed in a set of data from six experiments

10. Animal production and canopy attributes of Cynodon pasture managed under continuous stocking with wethers at three levels of forage allowance
The objective of the present experiment was to evaluate the effect of forage allowance (3, 6 or 9 kg of green leaves dry matter (DM)/100 kg of body weight (BW)) on both animal performance and attributes of Cynodon dactylon var.dactylon canopy managed under continuous stocking by wethers. The study was carried out with 27 Polwarth wethers throughout five 28-d
