1. Efeitos do fornecimento de dietas contendo nitrogênio não-protéico(NNP) sem prévia adaptação, durante curto espaço de tempo e em diferentes fases do ciclo estral na produção, qualidade e grau de desenvolvimento de embriões de fêmeas bovinas superovuladas / Effect of short term non-protein nitrogen (NPN) feeding to superovulated beef cows without previous adaptation, at different periods of the oestrus cycle on yield, quality and development degree of recovered embryos
High levels of crude protein (CP) in ruminant diets were associated with detrimental effect on fertility, mainly, due to the rise of plasmatic urea nitrogen (PUN) concentration. The aim of this study was to verify the effects of short term non-protein nitrogen feeding at different periods of the oestrus cycle in superovulated cows without previous adaptation
