Abstract
The objective of the study was to determine the effect of time of feeding pre-farrow on farrowing time and duration. Two hundred and ninety-eight (298) mixed parity sows were assigned to morning (0700 h) or evening (1900 h) feeding upon entry into the farrowing room until farrowing. More sows from the morning-fed group farrowed between 0700 and 1500 h than the evening-fed group (51.43 vs. 21.95%, P < 0.001). There were no differences (P > 0.10) in farrowing duration. Number of piglets born alive, stillborn, and mummies did not differ (P > 0.10) among treatments. Evening-fed sows had an increased number of pigs weaned, resulting from reduced preweaning mortality compared to the morning-fed sows (P < 0.05). Morning feeding may be beneficial for maximizing the number of farrowing events that start during working hours and evening feeding may improve litter outcomes.
