Concentrate and crude protein levels in diets for dairy Gyr lineage cows grazing elephant-grass during the rainy season Níveis de concentrado e proteína bruta em dietas para vacas da raça Gir linhagem leiteira sob pastejo de capim-elefante durante a época das águas

The objective of this work was to evaluate the effects of three levels of concentrate (2.0, 4.0 and 6.0 kg/cow/day) and two levels of crude protein (CP) (14 and 16% total dietary dry matter), in comparison to mineral mixture (control) on the intake, apparent digestibility, milk composition and yield...
