Abstract Previous research suggests an increase of the isoleucine (Ile) requirement for late finishing pigs. Diets containing dried distillers grains with solubles (DDGS) provide excess leucine which can lead to changes in available Ile due to the antagonistic relationship of branched chain amino acids. Therefore, the Ile requirement in finishing diets containing DDGS deserve to be re-evaluated. A finishing study was conducted to determine the standardized ileal digestible (SID) Ile:Lysine (Lys) requirement in diets containing 20% DDGS. Pigs (n = 2,268; 82.3 ± 0.39 kgs) were used in a 56-d trial (14 replicates per treatment). Pens were assigned to one of six dietary treatments balancing for previous treatment. Treatments consisted of a corn-soybean meal diet (CS) or diets containing 20% DDGS with a SID Ile:lys ratio of 55, 60, 65, 70, or 75%. Data was analyzed as a randomized complete block, pair-wise comparisons and single degree of freedom orthogonal polynomials (DDGS diets only) were used to evaluate treatment responses, and pen was the experimental unit. Increasing the SID Ile:Lys did not impact cumulative performance of pigs fed diets containing 20% DDGS (P > 0.175). Pigs fed CS had improved (P < 0.010) ADFI compared to pigs fed SID Ile:Lys of 65 and 75% and tended (P = 0.084) to have greater ADG than 55 and 75% Ile:Lys treatments. Feed efficiency did not differ due to treatment (P = 0.427). Increasing the SID Ile:Lys to 65% in 20% DDGS diets decreased back fat and increased loin depth (quadratic; P < 0.029) and tended to increase percent lean (quadratic; P = 0.076), but did not alter hot carcass weight (P > 0.428). Pigs fed CS diets had greater hot carcass weights (P < 0.031) compared to pigs fed DDGS diets except for pigs fed 60% Ile:Lys diets. These data suggest a SID Ile:Lys of 60% is required to maximize growth performance and SID Ile:Lys of 65% increases carcass traits in diets containing 20% DDGS.

Abstract Minimal research has investigated the valine (Val) requirement in grow-finish pig diets, especially when diets contain dried distillers grains plus solubles (DDGS). Therefore, the objective of this study was to determine the standardized ileal digestible (SID) Val:lysine (Lys) requirement in diets containing 30% DDGS. A total of 2,430 pigs (39.4 ± 0.21 kg) were used in a 28-d trial (15 replicates per treatment). Pens were randomly allotted within block to one of six dietary treatments: 30% DDGS diets with a SID Val:Lys ratio of 60, 65, 70, 75, and 80% or a corn-soybean meal diet (CS). Data were analyzed as a randomized complete block, pair-wise comparisons and single degree of freedom orthogonal polynomials (DDGS diets only) were used to evaluate treatment responses, and pen was the experimental unit. Straight broken line (SBL) and quadratic broken line (QBL) regression analysis was used to estimate the SID Val requirement. Increasing SID Val:Lys up to 70% in 30% DDGS increased final BW, ADG and G:F (quadratic; P < 0.001), while increasing SID Val:Lys up to 75% in DDGS diets increased ADFI (quadratic; P < 0.001) Pigs fed CS had greater (P < 0.032) ADG, G:F, and ADFI compared to diets containing 30% DDGS except for cumulative ADFI of pigs receiving diets with 75% SID Val:Lys (P = 0.167). The SBL analysis estimated SID Val:Lys requirement at 66.4, 65.4, and 68.0% for ADG, ADFI, and G:F of pigs from 39.4 to 52.9 kg of body weight (BW) and 66.8, 65.7, and 70.4% for the pigs between the BW of 52.9 and 66.4 kg. The QBL analysis revealed a similar SID Val:Leucine ratio of 52.2% for G:F in both periods. This data suggests a SID Val:Lys requirement of 66.6% in diets containing 30% DDGS for pigs between the BW of 39.4 to 66.4 kg. Increasing the SID Val:Lys ratio in 30% DDGS diets did not improve performance congruent to CS fed pigs.

A study was conducted on crossbred steers (n = 275; 376 ± 24 kg) to evaluate performance and carcass quality of cattle fed wheat or corn dried distillers’ grains with solubles (DDGS). The control ration contained 86.6% rolled barley grain, 5.7% supplement and 7.7% barley silage (DM basis). The four treatments included replacement of barley grain at 20 or 40% of the diet (DM basis) with wheat or corn DDGS. Steers were slaughtered at a common end weight of 645 kg with 100 steers randomly (n = 20 per treatment) selected for determination of the retail yield of sub-primal boneless boxed beef (SPBBB). Data were analyzed as a completely randomized design using pen as the experimental unit. Feeding increasing levels of wheat DDGS led to a quadratic increase in dry matter intake (DMI) (P < 0.01), whereas increasing levels of corn DDGS led to a quadratic decrease in DMI (P = 0.01). Average daily gain was not influenced (P = 0.13) by feeding wheat or corn DDGS, but cattle fed corn DDGS exhibited a quadratic increase (P = 0.01) in gain:feed. As a result, a quadratic increase (P < 0.01) in calculated NEg of the diet was observed as corn DDGS levels increased. A linear decrease (P = 0.04) in days on feed (169, 166 and 154 d) was noted when increasing levels of wheat DDGS (0, 20 and 40%) were fed. Dressing percentage increased in a linear fashion with wheat DDGS (P < 0.01) inclusion level and in a quadratic fashion (P = 0.01) as corn DDGS inclusion level increased although other carcass traits were not affected (P > 0.10) by treatment. The results indicate that replacement of barley grain with corn or wheat DDGS up to 40% of the diet (DM) can lead to superior performance (improved gain:feed or reduced days on feed, respectively) with no detrimental effect on quality grade or carcass SPBBB yield.Key words: Dried distillers’ grains with solubles, corn, wheat, feedlot performance, carcass quality, steers

Abstract A 112 d finishing study was conducted to evaluate the effects of feeding dried distillers grains plus solubles (DDGS) from the MSC-Fiber stream of the FluidQuip post-fermentation fiber separation process compared to conventional DDGS. Yearling crossbred steers (n = 240, initial BW = 463 ± 35kg) were blocked by initial BW, stratified by BW, and assigned randomly to pen (n = 30; 8 steers/pen). Treatments were arranged as a 2×2 + 1 factorial with DDGS type (MSC DDGS [MSC]; Conventional DDGS [CONV]) and inclusion level (20 or 40% diet DM) as the factors. All treatments were compared to a corn-based control (CON). DDGS replaced a 60:40 blend of high-moisture corn and dry-rolled corn. All diets contained 7.5% alfalfa hay and supplement. Data were analyzed as a randomized block design with pen as experimental unit and block as fixed effect. Increasing concentrations of CONV or MSC resulted in a linear increase in DMI (P &lt; 0.01). Steers fed 40% MSC had the greatest DMI (P &lt; 0.01) while CON steers had the least (P &lt; 0.02). Daily gains for MSC steers linearly increased (P = 0.03), while CONV steers showed a tendency for a quadratic response to ADG (P=0.08). Feed efficiency of CONV steers increased quadratically (P = 0.04) and tended to decrease linearly (P = 0.09) for steers fed MSC. Efficiency was greatest for 20% CONV but not different (P &gt; 0.16) than CON, or 20% MSC. Steers fed 40% MSC or 40% CONV were not different in feed efficiency. Inclusion of MSC DDGS resulted in linear increases in DMI and ADG over CON, but decreased feed efficiency by 1.0 and 5.3% resulting in MSC DDGS having a relative feeding value of 95.0 and 86.7% of corn at 20 and 40% DM, respectively.
