Como nossa exploração animal é realizada principalmente em pastagens, ganhou grandes vantagens comparativas. As pastagens utilizadas no pastejo animal podem ser nativas ou cultivadas, mas estas últimas predominam e são de maior importância. As gramíneas forrageiras cultivadas mais importantes em ...
0 Brasil é um país de dimensão continental e apresenta vários tipos de climas e solos. Mas, existe carência de genótipos de capins adaptados a ambiente sob estresse hídrico, o que torna necessário estudos que possam preencher essa lacuna. Esse trabalho teve como objetivo avali...
Forage legumes have high protein content, good development in relatively poor soil, easy propagation and can incorporate nitrogen to the soil. All these aspects promote a great benefit to the livestock production, including cost reduction on fertilizer in pastures. Species of the genus&...
Resumo: Com o objetivo de avaliar a toxicidade do cobre em ovinos, administrou-se sulfato de cobre a quatro grupos, nas dosagens de 15, 30, 60 e 120ppm, até surgirem os sinais da intoxicação; um quinto grupo permaneceu como controle. Estes animais foram submetidos a exames...
ABSTRACT - The objective of this study was to evaluate the effects of potassium (K) on disease severity and the chemical composition of Megathyrsus maximus cultivars. The experiment was conducted in a randomized block design in a 6 × 4 factorial arrangement, consisting of six&...
ABSTRACT - This systematic review aimed to synthesize evidence on the effects of nitrogen (N) fertilization on forage production, animal performance, and greenhouse gas emissions in tropical pastures. The research question was developed based on the PICOS strategy. A total of 84,629 doc...
Understanding forage quality is essential for meeting animal demands and optimizing production. This study aimed to: (i) test the applicability of machine learning models with tabular data such as climate variables, light interception (LI), nitrogen dose (N dose), interval between grazing (G...
ABSTRACT - Studies on morphogenesis and tillering are crucial for pasture productivity and sustainability, as forage production depends on tiller performance and population density. This two-year study assessed the impact of four grazing frequencies on tillering dynamics and morphogenesis traits ...
ABSTRACT - The increasing climate variability in tropical regions demands management goals that allow for shorter rest periods without compromising pasture persistence. The objective of this study was to evaluate the effects of four pre-grazing light interception (LI) levels on the structura...
Pastures of Brachiaria decumbens cv. Basilisk radically changed the scenario of central Brazil livestock production from the early 1970s and allowed the development of this vast region. Despite of the reasonable biomass yield and nutritional value, susceptibility to grassland spittlebugs limits&#...
