39.2 ± 2.2 kg) were greater (P < 0.01) with AL feeders than with HF feeders, respectively. Number of pigs weaned did not differ (P > 0.05, 9.7 ± 0.1). The AL sows tended to have greater (P = 0.07) wt gains during lactation (12.2 ± 3.1 vs. 8.2 ± 3.2 kg, AL and HF, respectively). Backfat change during lactation and wean-to-estrus interval did not differ (P >0.05). Sows with AL feeders wasted less (P < 0.01) water than sows with HF feeders (12.7 ± 14.8 vs. 236.0 ± 20.7 kg, respectively), but water intake and feed waste was similar (P > 0.05). Sows given ad libitum access to feed during lactation responded with productivity.
