Despalha da cana-de-açúcar e desempenho de novilhas e vacas leiteiras

Abstract: RESUMODois experimentos avaliaram a resposta em ganho de peso de novilhas e a produção de leite de vacas à remoção de folhas apicais e laterais da cana-de-açúcar. Em ambos, os animais foram alimentados individualmente em confinamento total. No Experimento 1, 32 novilhas Girolando (295±45kg de peso vivo) foram blocadas em pares e alocadas a um tratamento por 42 dias, após um período de padronização de 14 dias. Os tratamentos foram: cana integral ou despalhada. O peso vivo e o consumo foram mensurados ao longo d… Show more

“…The chewing, eating, and rumination times per unit DM intake were calculated using DM intake data from the two 24-h observation periods. The chewing activity per digestible organic matter intake (DOMI) was calculated using the organic matter digestibility (OMD) coefficient estimated for each heifer on days 54 and 55 of the experimental period (SIÉCOLA JÚNIOR et al, 2014).…”
