Sustainability: an updated look to dry matter intake and energy metabolism regulation on dairy cows

Abstract

One approach to achieve sustainability is to increase milk production in each animal. Milk production is directly associated with dry matter intake, greater dry matter intake greater milk yield. It is also important how each animal used or partition the energy intake. For this reason the study of regulatory mechanisms of dry matter intake and energy metabolism are important in milk production. Some important factors in this regulation are the hormones ghrelin, glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1.
