81 Increasing withdrawal duration of corn distillers dried grains with solubles on finishing pig performance and carcass characteristics

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to 1 of 5 dietary treatments, differentiated by the number of days prior to slaughter that diets containing DDGS were withdrawn and replaced with corn-soybean meal-based diets.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 Corn distillers dried grains with solubles (DDGS) are known to negatively impact carcass yield and fat quality, thus finishing pigs may need to be switched from diets containing DDGS to corn–soybean meal (CSBM) diets before marketing (DDGS withdrawal). A total of 860 finishing pigs (PIC C48 or L42 × 327; initially 66.2 kg body weight, BW) were used in a 76-day experiment to evaluate the effects of DDGS withdrawal periods at increasing intervals before harvest. Pen served as the experimental unit, and there were seven replicate pens per treatment with 23 to 25 pigs per pen. Pens were blocked by BW and allotted to one of five dietary treatments differentiated by the DDGS withdrawal period: 76, 42, 27, 15, or 0 day before harvest. Diets contained 40% DDGS from 22 to 66 kg prior to the experiment, 0% or 35% DDGS during the experiment from ~66 to 82 kg, and 0% or 30% DDGS until the completion of the trial. Diets were not balanced for net energy. Linear and quadratic response to time following dietary switch was evaluated using PROC GLIMMIX. For the overall period (day 76 prior to market to day 0), as withdrawal period increased, average daily gain (ADG) and final BW increased (linear, P < 0.002) and feed efficiency (G:F) improved (quadratic, P = 0.019). Average daily feed intake increased (quadratic, P = 0.030) as withdrawal period increased. There was an increase (linear P = 0.010) in hot carcass weight (HCW), with a marginally significant increase in carcass yield (linear, P = 0.094) with increasing withdrawal period. Loin depth and lean percentage did not demonstrate any evidence for treatment differences (P > 0.132). Backfat increased (linear, P = 0.030) with increasing withdrawal period. Finally, iodine value (IV) of belly fat was decreased (linear, P = 0.001) with increased withdrawal period. In conclusion, switching from a DDGS-based diet to a CSBM-based diet for longer periods before slaughter increased ADG and improved G:F, resulting in increased HCW. After diets were switched from DDGS to CSBM, pigs demonstrated an increase in intake, likely due to the ability to consume high volumes of feed after consuming high fiber (DDGS) diets. Belly fat IV was decreased as the length of time after dietary change was increased, with the lowest IV resulting from pigs that consumed CSBM for the entire experimental period.

The objective of this experiment was to determine the effects of feeding graded levels of Linpro (a 50:50 combination of extruded full-fat flax seed and peas) on pig performance and carcass traits, particularly the fatty acid composition of backfat. Eighty crossbred pigs (Camborough 15 Line female × Canabred sire, Pig Improvement Canada Ltd., Airdrie, AB) weighing an average of 22.7 ± 2.2 kg were assigned on the basis of sex, weight and litter to one of five dietary treatments in a 5 × 2 factorial arrangement (treatment × sex). The experimental diets were based on barley and soybean meal and contained 0, 7.5, 15, 22.5 or 30% Linpro during the growing period (22.7–69.7 kg) and 0, 6, 12, 18 or 24% Linpro during the finishing period (69.7–111.1 kg). Digestibility coefficients for dry matter were not significantly affected by incorporation of Linpro in the diet. Digestibility coefficients for crude protein (P = 0.01) and gross energy (P = 0.04) exhibited a cubic effect due to Linpro incorporation with the highest digestibility coefficients observed for pigs fed 7.5% Linpro. Over the entire experimental period (22.7–111.1 kg), daily gain was affected both linearly (P = 0.02) and quadratically (P = 0.04) by Linpro inclusion. The most rapid gains were obtained by pigs fed 7.5% Linpro (6% in finisher), while pigs fed 30% Linpro (24% in finisher) gained weight the slowest. Feed intake was not significantly affected by Linpro inclusion, while feed conversion exhibited a quadratic effect (P = 0.02) with pigs fed the highest and lowest levels o f Linpro showing the poorest feed conversion. Linpro inclusion, had no significant effects on carcass traits including slaughter weight, carcass weight, dressing percent, carcass value index, lean yield, loin fat or loin lean. Inclusion of 30% Linpro (24% in finisher) significantly (P < 0.05) increased the levels of linolenic acid in backfat and this increase could provide significant health benefits for consumers of pork. Linpro would appear to be an acceptable alternative to soybean meal as a protein supplement for use in growing-finishing swine diets and can be incorporated at levels as high as 22.5% in the grower period and 18% in the finisher period without detrimental affects on pig performance.

This study was conducted to determine the performance and carcass characteristics of growing-finishing pigs fed diets containing graded levels of canaryseed. Sixty-four crossbred pigs (Pig Improvement Canada Ltd) weighing 34.4 ± 2.8 kg were assigned on the basis of sex, weight and litter to one of five dietary treatments in a factorial (5 treatments × 2 sexes) arrangement. A barley and soybean meal diet served as the control. The remaining pigs were fed diets in which approximately 25, 50, 75 or 100% of the barley was replaced by canaryseed (cv. Elias). There was a linear (P = 0.01) decrease in dry matter digestibility with increasing level of canaryseed. In contrast, crude protein digestibility showed a linear increase (P = 0.01) with increasing level of canaryseed. Gross energy digestibility of the diets did not differ (P > 0.05). Over the entire experimental period (34.4 to 107.8 kg), there was a quadratic (P = 0.01) response for weight gain. The 25% canaryseed diet supported the highest growth rate and pigs fed the 100% canaryseed diet had the lowest gain. Feed intake and feed conversion were unaffected (P > 0.05) by level of canaryseed. There were no differences (P > 0.05) in carcass weight, carcass value index, estimated lean yield, loin fat depth or loin lean depth as a result of canaryseed inclusion. However, there was a quadratic (P = 0.02) response for dressing percentage with increasing level of canaryseed. The overall results of this experiment provide a favorable indication that canaryseed can be successfully fed to growing-finishing pigs without dramatically affecting pig performance or carcass characteristics. Therefore, in the future, the swine industry may provide an alternative to the caged bird market as an outlet for growers of canary seed to market their product.

Abstract A total of 1,215 pigs (L337×1050, PIC, Hendersonville, TN) were used in a 156-d wean-to-finish experiment. Pigs were weaned at 21 d of age and placed in pens based on initial body weight (BW) with 27 pigs/pen. There were three dietary treatments including a: 1) control; 2) pigs fed diets containing AviPlus (micro-encapsulated sorbic and citric acids and synthetic thymol and vanillin botanicals; Vetagro Inc., Chicago, IL) during the nursery and finisher phases; or 3) pigs fed AviPlus during the nursery but not the finishing phase. AviPlus was included at 2.72 kg/ton from d 0 to 21, 0.90 kg/ton from d 21 to 42, and 0.45 kg/ton from d 42 to 156. Thus, there were 15 control pens and 30 Aviplus pens in the nursery and 15 pens for the 3 treatments in the finisher phase. On d 42, pigs were transported as intact pens to the finishing facility. Data were analyzed as a RCBD with pen as experimental unit. For the overall nursery period (d 0 to 42), pigs fed AviPlus had improved (P < 0.05) G:F, with no evidence of difference (P > 0.05) for d 42 BW, ADG, or ADFI. For the overall finishing period (d 42 to 156) and overall experimental period (d 0 to 156), there was no evidence of difference (P > 0.05) for BW, ADG, ADFI, or G:F. There was no evidence of difference (P > 0.05) observed for mortality and removals during the nursery, finisher, or overall. In summary, providing AviPlus during the nursery improved nursery G:F, but there was no effect on overall wean-to-finish performance.

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.

Effect Of Feeding

Abstract Four hundred and sixty-six late finishing pigs (initial BW = 106.49 kg) were used to evaluate the effect of feeding Ambitine™ Feed Additive (Ambitine™ FA) on late finishing performance. Ambitine™ FA is a blend of plant extracts and acidifiers. Pigs were allotted in a randomized complete block design into mixed gender pens, with 11 replicates per treatment, 21 pigs per pen, and fed 1 of 2 dietary treatments. Dietary treatments were Control (corn-soybean meal-20% DDGS with 6.75g of Paylean® formulated to 0.95% TID lysine) or Control plus Ambitine™ FA (0.10%) fed the last 34 days of the finishing period. Body weights were taken at day 0, 8, 20, and 34 with corresponding ADG, ADFI, and GF calculated for each period. Data were analyzed using the Mixed procedure in SAS with pen as the experimental unit. Period 1 (d 0–8) ADG tended to increase (P = 0.09; 1.32 vs 1.25, kg/d) and G:F increased (P = 0.02; 0.408 vs 0.375) with Ambitine™ FA treatment. Period 1, ADFI was not significantly different between treatments. Period 1 BW tended (P = 0.09) to increase for the Ambitine™ FA treatment (117.07 vs 116.46 kg). Period 2 (d 8–20) ADFI increased (P = 0.05; 2.99 vs 2.93 kg/d) with Ambitine™ FA treatment, and ADG and G:F were not significantly different between treatments. Period 3 (d 20–34) growth performance was not significantly different between treatments. Ambitine™ FA increased (P = 0.03) overall (d 0 to 34) ADG (1.27 vs 1.21, kg/d) and G:F ratio (0.402 vs 0.382). Plant Live weight tended (P = 0.09) to increase for the Ambitine™ FA treatment (131.96 vs 128.85, kg). Total gain was increased (P = 0.002) with the Ambitine™ FA treatment (26.57 vs 24.44 kg). The results of this study suggest that feeding Ambitine™ FA improves growth rate and feed efficiency in finishing pigs.

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 This study was conducted at a commercial research facility and utilized 1,092 finishing pigs (PIC® 337 × Camborough®) in a RCBD with 3 dietary treatments to determine the effects of commercially available phytogenic feed additives on growth performance traits in finishing swine for the last 35 d prior to marketing. The dietary treatments were as follows: 1) Control; 2) Aromex Pro® (AP; Delacon) fed at 0.01%; and 3) Ambitine® (AM; PMI) fed at 0.1%. Pens with 13 pigs/pen and 0.66 m2/pig were randomly allotted to treatments on the basis of live weight and gender. Pigs had ad libitum access to corn-soy diets that met or exceeded the pig’s requirements (NRC, 2012). Aromex Pro® and Ambitine® were added to the diets at the expense of corn. Dietary treatments started on day 0 (BW = 97.7 kg; SEM = 1.04) and were fed throughout the 35 d trial period. On d 21, the two heaviest pigs per pen were marketed, while the remaining pigs in each pen were marketed on d 35. Pigs and feeders were weighed on d 0, 21, and 35. Data were analyzed by using PROC MIXED of SAS® version 9.4, and pen was the experimental unit. The model included the fixed effect of treatment and random effect of replicate. Pre-planned orthogonal contrasts were used to compare AP vs. Control and AM vs. Control. Feeding AP or AM for the last 35 d in finishing both improved (P < 0.05) ADG by 4%, ADFI by 3% and final BW by 1.6 kg over Control, but did not change feed to gain or mortality. These data demonstrate that phytogenic feed additives can improve growth performance traits in finishing swine.

Abstract The study was conducted to assess the effect of black pepper (BP) supplementation on the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs. A total of 180 crossbred [(Landrace × Yorkshire) × Duroc] finishing pigs with average initial body weight (BW) of 53.72 ± 1.42 kg were used in 10-week trial and allotted to 6 dietary treatments (6 replications pens/treatment with 5 pigs per pen). The dietary treatments were: CON (basal diet), TRT1- CON + 0.025% BP, TRT2- CON + 0.05% BP, TRT3- CON + 0.1% BP, TRT4- CON + 0.2% BP, TRT5- CON + 0.4% BP. A linear increase (P = 0.0380, 0.0061) in body weight gain (BWG) and average daily gain (ADG) were observed respectively, during the overall trial in pigs fed BP supplemented diet compared to control. The dietary supplementation of BP showed a linear increase (P=0.0065) in gain and feed ratio (G: F) at week 10. However, there were no significant results observed on average daily feed intake (ADFI) during the overall experiment. The total tract digestibility of dry matter (DM) was linearly improved (P=0.0531) in BP treatment groups compared to control. In addition, BP diet supplementation had linearly increased fecal Lactobacillus counts (P=0.0482) and decreased E. coli counts (P=0.0306) in pigs at week 10. Furthermore, NH3, methyl mercaptans, and acetic acid was linearly decreased (P=0.0227, 0.0555,0.0541) in pigs fed BP supplementation compare to control. The inclusion of BP supplementation in pigs diet had linearly increased (P=0.0146) the backfat thickness at week 10. Thus, we concluded that BP supplementation had positively enhanced the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs.

Diet Type

In experiment, six pigs fitted with a T-cannula at the distal ileum were fed six diets in a 6×6 Latin square design. Treatments were corn-soybean meal diet (CS), diet containing wheat by-products (WBP), and diet containing corn distillers dried grains with solubles and canola meal (DDCM) without or with xylanase (X) supplementation (CS-X, WBP-X and DDCM-X). The WBP and DDCM diets had higher AID of lipids and ADF (P < 0.05) than CS diets. A xylanase×diet interaction was observed for the AID NDF (P < 0.05) showing larger impact of xylanase in WBP than in the other diets. Using similar dietary treatments except for CS-X, growth and body composition of the sixty males (83.0 kg) at the end of the d28 growing phase showed that pig fed the CS had greater ADFI (P = 0.004) and ADG (P = 0.014) for period 0-14d but not from 15 28d. Overall performance (0-28d) showed higher ADFI (9.5%; P = 0.015) in CS but no difference was observed for ADG and G:F. These results showed that diets containing a high proportion of by-products can give equivalent performance to a CS diet and that adding xylanase for this short period had limited.
