title: Insulin-like growth factor-I, GH, insulin and glucagon concentrations in bovine colostrum and in plasma of dairy cows and neonatal calves around parturition.
abstract: 1. The IGF-I concentrations in colostrum on days 1 and 2 after parturition were higher than those in cow and neonate plasma. 2. The modest increase in GH concentrations in cow plasma around parturition would not be enough to stimulate IGF-I release by tissues. 3. The concentrations of insulin, GH and glucagon in colostrum were substantially lower than those in plasma.
