Abstract Text:

The objective of this study was to determine the effects of liquid feeding distillers dried grains with solubles (DDGS), wet distillers grains with solubles (WDGS), wet distillers grains (WDG), wet distillers soluble (WDS), and freeze-dried distillers solubles (DDS) on the performance of wean-finish pigs. A total of 480 pigs with initial BW 11.3±1.5 kg were blocked by BW and gender and randomly allocated to 1 of 6 dietary treatments: 1) corn-soybean meal (Control), 2) 30% DDGS (DDGS), 3) 30% DDS in the first 2 weeks (phase 1) and 30%  DDGS for the remaining phases (DDS), 4) 20% WDS (WDS), 5) 30% WDG (WDG), 6) 30 % WDGS (25.5 % WDG + 4.5 % WDS, WDGS). Conventional dry feeding was applied for treatments 1, 2, and 3, whereas pigs from treatments 4, 5, and 6 were fed using a liquid feeding system. Each treatment had 4 pens of barrows and 4 pens of gilts with 10 pigs per pen. Pigs on liquid feeding had better feed efficiency, lower ADFI, and higher water intake (P < 0.05) when compared with those on dry feeding. However, no difference (P > 0.05) was observed for ADG between the liquid feeding and dry feeding for all phases except that dry feeding resulted in higher ADG (P < 0.05) during d 42 to 70 in comparison with liquid feeding. During d 14 to 42, the WDS group had lower ADG compared with the WDG group (P < 0.05). During d 42 to 70, the corn-soybean diet had greater ADG than the WDS and WDG treatments, and WDS decreased ADG in comparison with the two dry feeding groups DDGS and DDS (P < 0.05). For the overall period and other feeding phases, ADG did not differ among the 6 dietary treatment groups (P > 0.05). No differences in ADFI, feed efficiency, and water intake were found among the 3 groups within the same feeding type for all phases (P > 0.05). Our results suggest that liquid feeding of ethanol industry co-products to wean to finish pigs does not compromise growth performance.
