Abstract Two experiments evaluated the effects of removing corn DDGS from diets at increasing intervals before harvest on finishing pig performance and carcass characteristics. For Exp. 1, 985 pigs [PIC TR4×(Fast LW×PIC L02); initially 99 kg BW] were used in a 28-d study. There were 12 pens/treatment and four treatments decreasing in duration of DDGS withdrawal before marketing: 28, 21, 14, or 0 d. All pens were marketed by removing the 17% heaviest pigs on d -21 with remaining pigs marketed at final barn dump (d 0). Overall, there was no evidence for effects of DDGS withdrawal on final BW, ADFI, or G:F (P > 0.112); however, as withdrawal time increased, ADG increased (linear, P = 0.022) and iodine value (IV) decreased (linear, P = 0.001). There was no evidence for differences for HCW or loin depth (P > 0.106); however, yield increased (linear, P = 0.001) with increasing withdrawal time. Backfat depth decreased (quadratic; P = 0.019) and percentage lean increased (quadratic; P = 0.033) as DDGS withdrawal time increased. In Exp. 2, 1,158 pigs (initially 105 kg BW) were used in a 35-d study. There were 15 pens/treatment and four treatments decreasing in duration of DDGS withdrawal: 35, 28, 14, or 0 d. All pens were marketed by removing the 15% heaviest pigs on d -28, the 28% next heaviest pigs on d -14, with final barn dump of approximately 57% of starting inventory (d 0). There was no evidence that final BW, overall ADG, or G:F differed across treatments with increasing DDGS withdrawal times (P > 0.116). Overall ADFI increased (linear, P = 0.015) as time withdrawn from DDGS increased. Iodine value decreased (linear; P = 0.001) and yield increased (linear; P = 0.034) with increasing withdrawal time, with no evidence for differences in HCW, backfat, loin depth, or percentage lean (P > 0.05). These experiments suggest that longer withdrawal of DDGS prior to marketing improves carcass yield and decreases IV.

Abstract The effect of corn distillers dried grains with solubles (DDGS), used in grower-finisher diets with or without supplemental enzymes, on growth performance and carcass and meat quality was determined in an experiment with 48 pigs. Group I (control) received a standard grain-soybean meal mixture without DDGS and without enzymes; Group II was fed a mixture containing 15% (grower) or 20% (finisher) of corn DDGS but without the enzymes; Group III received a mixture containing 15% (grower) or 20% (finisher) of corn DDGS with NSP-hydrolyzing enzymes (200 g t-1). The feed mixtures were isonitrogenous and isoenergetic. All pigs were fattened from 30 to 112 kg. At the end of the experiment all pigs were slaughtered, right carcass sides were evaluated and samples of longissimus muscle were taken for analysis. Inclusion of corn DDGS did not significantly affect pig fattening results and meat quality. The addition of NSP-hydrolyzing enzymes to feed mixtures containing corn DDGS tended to positively influence pig performance. The carcasses of pigs receiving the diet with corn DDGS and NSP-hydrolyzing enzymes were characterized by thinner backfat and greater weight of the primal cuts.

Abstract A total of 860 finishing pigs (PIC C48/L42×327; initially 66.2 kg BW) were used in a 76-d experiment to evaluate the effects of removing corn DDGS from diets at increasing intervals before harvest. Diets contained 40% DDGS prior to the experiment, 0 or 35% DDGS during the experiment from approximately 66 to 82 kg and 0 or 30% DDGS until the completion of the trial. Pen served as the experimental unit, and there were 7 replicate pens/treatment with 23 to 25 pigs/pen. Pens were blocked by BW and allotted to 1 of 5 dietary treatments, differentiated by the number of days prior to slaughter that diets containing DDGS were withdrawn and replaced with corn-soybean meal-based diets. Withdrawal times were 76, 42, 27, 15, or 0 d (no withdrawal) before harvest. Linear and quadratic response to withdrawal time was evaluated using PROC GLIMMIX. For the overall period (d -76 to 0), as time of DDGS withdrawal increased, ADG and final BW also increased (linear, P < 0.018) and G:F improved (quadratic, P = 0.019). Average daily feed intake quadratically decreased (P = 0.030) with increasing withdrawal time. There was a linear increase (P = 0.010) in HCW, with a marginally significant increase in carcass yield (linear, P = 0.094) with increasing DDGS withdrawal time. Loin depth and lean percentage did not demonstrate any evidence for treatment differences (P > 0.132). Backfat was linearly increased (P = 0.030) with increasing DDGS withdrawal time. Lastly, iodine value (IV) of belly fat was increased (linear, P = 0.001) with increased feeding duration of DDGS. In conclusion, removing pigs from diets containing DDGS for longer periods before slaughter increased ADG and improved G:F, resulting in increased HCW. Belly fat IV was decreased as the length of DDGS withdrawal increased, with the highest IV resulting from pigs that consumed DDGS for the entire experimental period.

Abstract Previous research has indicated that starch gelatinization during the pelleting process is greater for Enogen® Feed corn compared to conventional yellow dent corn. Increasing starch gelatinization in the pellet increases the starch digestibility in the pig, which potentially leads to increased growth rate. Therefore, the objective of this study was to determine the effects of feeding Enogen Feed corn in meal or pellet form on finishing pig growth performance and carcass characteristics. A total of 288 pigs (53.0 ± 0.5 kg) were used with 8 pigs/pen and 9 pens/treatment in a 72-d study. Treatments were arranged in a 2×2 factorial with main effects of corn source (Enogen Feed corn or conventional yellow dent corn) and diet form (meal or pellet). Main effects of corn source and diet form as well as their interactions were tested. Pelleting parameters were established with a target conditioner temperature of 82.2°C and corn moisture of 13 to 14%. When pelleting the diets, the conditioning temperature for conventional yellow dent corn averaged 68.4°C and Enogen Feed corn averaged 67.7°C. The hot pellet temperature for conventional yellow dent corn averaged 75.1°C and 75.8°C for Enogen feed corn. For overall performance (d 0 to 72), no interactions between corn source and diet form were observed (P &gt; 0.05). There was a tendency (P &lt; 0.10) for slightly improved average daily gain (ADG) and gain:feed ratio (G:F) for pigs fed conventional yellow dent corn compared to those fed Enogen Feed corn. Pigs fed pelleted diets had increased (P &lt; 0.001) ADG, G:F, and hot carcass weight compared to pigs fed meal diets. In summary, feeding pelleted diets to finishing pigs increased ADG and G:F compared to those fed meal-based diets. There were no major differences observed between corn sources or interactions between corn source and diet form on growth performance.

Abstract Genetic modification of corn has enhanced the use of different corn hybrids in animal agriculture. Enogen Feed corn, developed by Syngenta Seeds (Downers Grove, IL), has potential for use in livestock diets due to increase α-amylase enzyme in the corn thus improving starch digestibility. In addition, the pelleting process also increases starch gelatinization which increases its digestibility by the pig, increasing growth rate and improving feed efficiency. Therefore, pelleting Enogen Feed corn might prove to provide a greater response in growth performance than conventional yellow dent corn. Thus, the objective of this experiment was to determine the effects of corn source and diet form on growth performance and carcass characteristics of finishing pigs. A total of 288 pigs (53.0 ± 0.5 kg) were used with 8 pigs per pen and 9 pens per treatment in a 72-d study. Treatments were arranged in a 2 × 2 factorial with main effects of corn source (Enogen Feed corn or conventional yellow dent corn) and diet form (meal or pellet). For overall (d 0 to 72) performance, no interactions between corn source and diet form were observed. There was a tendency (P &lt; 0.10) for slightly improved average daily gain (ADG) and gain:feed ratio (G:F) for pigs fed conventional yellow dent corn compared to those fed Enogen Feed corn. For feed form, pigs fed pelleted diets had increased (P &lt; 0.001) ADG and G:F compared to pigs fed meal diets. For carcass characteristics, pigs fed pelleted diets had increased hot carcass weight compared to pigs fed meal diets (P &lt; 0.001). In summary, feeding pelleted diets to finishing pigs increased ADG and improved feed efficiency compared to those fed meal-based diets. There were no major differences between observed corn sources or interactions between corn source and diet form on growth performance.

Abstract The purpose of this experiment was to determine the effect of corn DDGS as a feed ingredient on egg quality and performance of laying hens. The experiment was conducted in three feeding groups of 100 hens each (10 replicates of 10 layers). ISA Brown laying hens were administered a feed mixture containing 15% (E1) or 20% (E2) corn DDGS for 18 weeks. The hens from the control group (C) received a standard diet based on soybean meal as the main protein source only. Laying performance, average egg weight, average daily feed intake and feed conversion ratio were recorded over the study period. Egg quality traits (egg weight, thick albumen quality, yolk colour, yolk content, shell content and shell thickness) were evaluated twice: at the start and at the end of the experiment. On both dates, all daily laid eggs from each group were analysed, i.e. 90, 93 and 92 eggs from groups C, E1 and E2, respectively at 31 weeks, and 92, 94 and 81 eggs, respectively at 48 weeks of age. Compared to the other groups, the hens from group E2 (20% DDGS) were characterized by a slight - though statistically significant (P≤0.01) - decrease in laying performance and by a higher FCR value. The content of DDGS in the feed mixture had no significant effect on mean egg weight nor on daily feed intake. At the end of the experiment, the eggs laid by the hens from group E2 were characterized by significantly poorer (P≤0.01) albumen and shell quality. Yolk colour in both experimental groups was significantly darker (P≤0.01) than in the C group. The 15% addition of corn distillers dried grains with solubles to feed mixtures for commercial flocks of laying hens is advisable. At corn DDGS addition exceeding 15%, a slight decrease in production results and deterioration in selected parameters of egg quality shall be expected.

Abstract A total of 288 pigs (DNA 600 × 241; initially 50.7 kg) were used in an 86-d experiment to determine the effect of dietary fiber source on finishing pig performance. Thirty-six pens of 4 barrows and 4 gilts/pen (total 8 pigs/pen) were randomly assigned to 1 of 3 dietary treatments. Treatments consisted of a corn-soybean meal control (8.7% neutral detergent fiber, NDF), 20% dried distillers grains (DDGS; 13.6% NDF) or 14.5% sugar beet pulp (SBP; 13.6% NDF). Experimental diets were fed from d 0 to 86 in 3 phases. Diets were balanced to constant NE and SID lysine within phase. Net energy values for ingredients were 2,672 kcal/kg, 2,343 kcal/kg, and 1,734 kcal/kg for corn, DDGS, and SBP, respectively. Overall, there was no evidence for treatment difference in ADG or ADFI. Pigs fed DDGS had a tendency for poorer G:F compared to pigs fed the control or 14.5% SBP diets (P < 0.10). Caloric efficiency of net energy (NE) was poorer (P < 0.10) in pigs fed DDGS compared to those fed control and SBP. There was a tendency for decreased (P < 0.07) hot carcass weight and decreased (P < 0.05) carcass yield in pigs fed DDGS and SBP compared to those fed the control diet. Loin depth tended to decrease (P < 0.10) in pigs fed SBP compared to the control with pigs fed DDGS being intermediate. Therefore, pigs fed DDGS tended to have poorer feed efficiency compared to those fed the control diet or SBP. This can be explained by the overestimation of NE demonstrated by an increase in caloric efficiency. Increasing dietary NDF reduced carcass yield. http://www.conferenceharvester.com/
