The experiment evaluated the effect of dry period length and prepartum fat supplementation on energy balance (EB) and production of cows. The experiment was conducted in batches: in the first batch, cows were assigned randomly to either a traditional 60-d dry period (TDP) or a short 30-d dry period (SDP); in the second batch, cows were assigned to TDP, SDP, or SDP with fat supplementation (SDP-F). SDP treatments had better postpartum EB but less milk than TDP cows. SDP-F cows tended to produce more 105-d total milk than SDP. SDP treatments improved uterine health than TDP on 21 d postpartum.<br>
