Glicerina bruta na dieta de vacas lactantes mantidas em pastagem tropical: comportamento ingestivo

Abstract: ResumoObjetivou-se com este estudo avaliar o comportamento ingestivo de vacas lactantes mantidas em pastagem tropical suplementadas com diferentes níveis de glicerina bruta na dieta. Foram utilizadas 10 vacas lactantes, ¾ Holandesa x ¼ Gir Leiteiro, primíparas, com 109 ± 24 dias de lactação, idade média de 30 ± 6 meses e peso corporal médio de 426,2 ± 68,29 kg, distribuídas em cinco tratamentos, utilizando-se dois quadrados latinos cinco por cinco (5x5), Os tratamentos foram constituídos pelos níveis de inclus… Show more
