Caracterização de pastagem nativa com predominância de Eragrostis plana Nees e desempenho reprodutivo de vacas primíparas suplementadas

Abstract: RESUMOForam avaliadas as características produtivas e estruturais de uma pastagem nativa com predominância de capimannoni (Eragrostis plana Nees) e sua relação com desempenho reprodutivo de vacas primíparas suplementadas com sal comum, sal mineral, sal proteinado e sal reprodução. O delineamento experimental foi inteiramente casualizado com parcelas subdivididas no tempo. Houve diferença significativa (P<0,05) dos componentes estruturais entre períodos, com maior oferta de folha (6,3%), colmo (4,1%) e espécies… Show more

“…The fiber content increased to 90.43% (NDF) and 42.83% (ADF), while CP decreased from 9.96% to 3.94%. Pellegrini et al (2012) verified similar values for these nutritional components in leaves of the tough lovegrass (CP= 6.4-8.9%; NDF= 80.2-82.4%). The bromatological evaluation confirmed the inadequacy of this grass as forage plant, because for ruminants, CP levels lower than 7% are a limiting factor for rumen microorganisms, whereas high fiber levels compromise the consumption and nutrient utilization of the forage plant.…”
