摘要: Circulating concentrations of both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1(7-36)amide (GLP-1) were determined in dry lactating sheep. Both polypeptides significantly higher animals compared with dry. The half-life plasma was by intravenous injection GIP or GLP-1 animals, but neither peptide showed a different value during lactation. Thus, the increased circulating lactation must result from secretion, probably resulting feed intake Serum insulin lower lactation, which poses question how maintain levels presence agents.
