With the objective of evaluating different levels of IGF-I on the hepatical and intestinal indicators of cellular activity in newborn calves, 42 pregnant Holstein cows were randomly assigned to two groups: a) control: injection of vitamin E or b) rbST: injection of growth hormone (rbST). Injections started 35 days pre-partum and were repeated every 14 days until parturition. Newborn calves were randomly assigned to a 2 x 3 factorial arrangement of treatments (two mother groups and three different ages). After […]
