Abstract: Contrary to assertions in the editorial and Special Communication, administration of bST does significantly change milk composition, mainly reflecting tissue utilization to make extra milk, such as an increase in long-chain fatty acids. One importantexception is the increase in insulinlike growth factor I (IGF-I) to levels found usually in the first 2 weeks of …
