| ABSTRACT Ten Holstein-Zebu crossbred cows distributed into two simultaneous Latin squares (5 × 5) as a 2 × 2 factorial arrangement formed by chopped sugarcane or elephant grass silage, both with high or low protein degradability supplements and a corn silage as a control treatment, were compared using orthogonal contrasts. The studied variables were the performance, plasma concentrations of urea-N, glucose, and creatinine, urine-N and milk urea-N, and the nychthemeral variation in NH3-N in the rumen fluid of dairy cows. Nutrient intake, milk production, and milk composition were affected by the treatments. The total mixed ration containing elephant grass silage combined with rumen undegradable protein (RUP) provided balanced amounts of carbon and nitrogen... |

| Pennisetum purpureum has an extended use as forage and further knowledge related to the seasonal influence and fertilization could improve its cultivation. The effects of dry and rainy season and application of fertilizers (200-60-00), on the yield of four varieties of P. purpureum (Taiwan, OM-22, Maralfalfa, CT-115), and a homogeneous mixture of them were evaluated. The study, with four replicates, was conducted at Instituto Nacional de Investigaciones Forestales Agrícolas y Pecuarias, Tizimín, México, and lasted 10 months. Dry matter (DM), crude protein, leaf/stem ratio, stalks per cluster, and plant height, were assessed. Mean values of DM of all treatments in rainy season were significantly different with respect of dry season (36 and 28 t ha-1). Dry... |

| A produção de sementes de forrageiras tropicais representa um importante segmento da indústria de sementes no Brasil e há a necessidade do estabelecimento de prioridades para aumentar a eficiência do setor. Neste documento estão apresentados os resultados da discussão efetuada pelo grupo de trabalho reunido durante o Workshop "Tecnologia de Sementes de Forrageiras Tropicais: Demandas Estratégicas de Pesquisa", realizado pela Embrapa Gado de Corte em abril de 2008. As demandas de pesquisa discutidas e consideradas prioritárias foram pertinentes a vários aspectos da produção e tecnologia de sementes de forrageiras tropicais, da semeadura ao processamento, bem como ao armazenamento e análises laboratoriais. |
