Embrapa Gado de Leite has the main Elephant Grass Germplasm Active Bank (BAGCE) in the country. However, the main species of grasshopper (Hemiptera: Cercopidae) and the genetic variability for resistance to these pest insects were not known. Therefore, the objective of this work was to study the population dynamics of spittlebugs and to evaluate the accessions of the elephant grass germplasm bank, regarding resistance to Mahanarva liturata. The population dynamics of cercopids in Coronel Pacheco

The growing biofuel industry generates by-products that have shown promise as energy and protein feeds in ruminant diets. The objective of this project was to determine the effects of by-products of biodiesel production, obtained from different sources of oilseeds, on the in vitro degradability of nutrients, in vitro ruminal fermentation and methane gas production. Palisadegrass ( Brachiaria brizantha) was used as a model. Its isolated incubation was considered as a contro ...
