Suplementos para ovinos mantidos em pastos de capim-marandu [PDF]
O objetivo deste trabalho foi avaliar o efeito da suplementação na resposta produtiva, no pH e no nitrogênio amoniacal ruminal, e no custo de produção de ovinos em pastagem de capim-marandu no período da seca. O experimento teve a duração de 84 dias. Utilizaram-se 20 cordeiros não castrados com idade e peso corporal inicial médios de quatro meses e 24 ...

Urochloa species are widely used in silvopastoral systems (SPS), but production losses highlight the need for more productive forages. This study evaluated agronomic, physiological, chemical composition, and in vitro digestibility responses of Urochloa brizantha cv. Piatã and Megathyrsus maximus cvs.

Homecoming of Brachiaria: improved hybrids prove useful for African animal agriculture [PDF]
Species of the genus Brachiaria originate primarily from Africa, where they are constituents of natural grasslands. Due to their adaptation to acidic, low-fertility soils, millions of hectares of Brachiaria species have been sown as improved pastures in ...

Aspectos da Reprodução em Brachiaria brizantha cv. Marandu [PDF]
Two modes of reproduction are found in plants, sexual and asexual. Apomixis is an asexual reproduction mode through seeds. Apomictic plants give rise to embryos identical to the mother plant through parthenogenesis of a non-reduced egg cell. This feature is very important to agriculture, once incorporated in genotypes of agronomic importance, it allows

Performance of Beef Cattle Under Grazing as Affected by Urochloa decumbens Cultivars
ABSTRACT Testing animal performance under grazing is fundamental to determine the potential of recently released, high‐yielding Urochloa decumbens hybrids. The objective was to evaluate the weight gain of young bulls grazing on pastures of U. decumbens cultivars Basilisk, BRS Carinás, and BRS Poraitê, as well as to assess the nutritive value and plant ...

Calibration and evaluation of a carbon net primary productivity module based on the SIMPLE model
Abstract This study presents the carbon net primary productivity (CNPP) module, an implementation of the simple generic crop model (SIMPLE model) that we have extended to predict aboveground and belowground biomass production and carbon assimilation. The goal for this module is to predict biomass inputs at and below the soil surface, during and at the ...

Rebrota do capim-marandu submetido ao ataque de cigarrinhas [PDF]
O objetivo deste experimento foi caracterizar e quantificar respostas de Brachiaria brizantha cv. Marandu sob níveis de infestações de cigarrinhas adultas do gênero Mahanarva (Hemiptera: Cercopidae). O ensaio foi realizado em casa de vegetação na Cidade de Piracicaba, SP, e seus tratamentos corresponderam a quatro níveis de infestações de cigarrinhas ...
