چکیده
The inclusion of high concentrations of DDGS (30%) in both the nursery and growing-finishing periods may result in negative effects on growth performance and carcass characteristics. Summary The objective of this experiment was to evaluate the efiects of high concentrations of distillers dried grains with solubles (DDGS; 30%) on growth performance and carcass characteristics ofgilts, duringgrowing-finishing, that were previously fed high concentrations of DDGS during the nursery phase. Overall (week I 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 duringgrowing-finishing compared to pigs that did not receive DDGS in the nursery; 2) amongpigs that received DDGS duringgrowing-finishing, ADG tended (P < 0.10) to be lower compared to pigs that did not receive DDGS duringgrowing-finishing; and 3) amongpigs that received DDGS in both the nursery and duringgrowing-finishing , ADG and final BW was decreased (P < 0.04) compared to pigs with no prior exposure to DDGS. With respect to carcass characteristics, loth-rib back fat was greater (P < 0.05) at the end offin-isher 2 amongpigs that did not receive DDGS in the nursery and hot carcass weight tended (P < 0.07) to be decreased amongpigs that received DDGS in both the nursery and duringgrowing-finishing. This research indicates that the inclusion of high concentrations of DDGS in both the nursery and growing-finishingperiods may result in negative efiects on growth performance and carcass characteristics.

A study with 3 experiments was conducted to determine the AA digestibility and energy concentration of deoiled (solvent-extracted) corn distillers dried grains with solubles (dDGS) and to evaluate its effect on nursery pig growth performance, finishing pig growth performance, and carcass traits. In Exp. 1, a total of 5 growing barrows (initial BW = 30.8 kg) were fitted with a T-cannula in the d...

Sixty-four yearling steers (345 ± 4.2 kg BW) were used to study the effects of degree of dryrolled corn processing and corn dried distillers grains plus solubles (DDGS) inclusion on feeding and ruminating behavior, G:F, and carcass characteristics. Steers were assigned randomly to 1 of 4 experimental treatments (n = 16 per treatment): 1) coarse-rolled (2.68 mm) corn and 20% DDGS, 2) coarse-roll...

This study was conducted to determine the effects of dietary crude glycerol and dried distillers grains with solubles (DDGS) on growing-finishing pig performance, carcass characteristics, and carcass fat quality. We hypothesized that because dietary crude glycerol has been observed to increase carcass SFA, it might ameliorate the negative effects of DDGS on fat quality. The 97-d study was condu...

The objectives of this study were to determine the effects of conjugated linoleic acid (CLA) or betaine on the growth performance, carcass characteristics and fatty acid composition in backfat and belly fat of pigs fed distillers dried grains with solubles (DDGS). Thirty-two (60±2 kg) crossbred barrows (Duroc×Landrace×Yorkshine) were assigned to one of four diets randomly: (1) the control diet ...
