Abstract

The objective of this experiment was to evaluate the effects of high concentrations of distillers dried grains with solubles (DDGS; 30%) on growth performance and carcass characteristics of gilts, during growing-finishing, that were previously fed high concentrations of DDGS during the nursery phase. Overall (week 1 to 16), the following observations are noteworthy: 1) among pigs that were fed DDGS in the nursery, average daily gain (ADG) and final body weight (BW) tended (P < 0.10) to be lower during growing-finishing compared to pigs that did not receive DDGS in the nursery; 2) among pigs that received DDGS during growing-fi nishing, ADG tended (P < 0.10) to be lower compared to pigs that did not receive DDGS during growing-finishing; and 3) among pigs that received DDGS in both the nursery and during growing-finishing, ADG and fi nal BW was decreased (P < 0.04) compared to pigs with no prior exposure to DDGS. With respect to carcass characteristics, 10th-rib back fat was greater (P < 0.05) at the end of finisher 2 among pigs that did not receive DDGS in the nursery and hot carcass weight tended (P < 0.07) to be decreased among pigs that received DDGS in both the nursery and during growing-finishing. This research indicates that the inclusion of high concentrations of DDGS in both the nursery and growing-finishing periods may result in negative effects on growth performance and carcass characteristics.
