Abstract An experiment was conducted to determine the effects of L-Lys HCl inclusion in diets with or without distillers dried grains with solubles (DDGS) on growth performance of finishing pigs. A total of 2,414 pigs (initial BW = 92.7 kg) were used in a 34-d trial. Treatments were arranged as a 2 × 3 factorial treatment structure with two levels of DDGS (0 or 10%) and three levels of L-Lys HCl (0.2, 0.3, or 0.4%). Diets were corn and soybean meal-based and were formulated to be isocaloric (NE = 2,668 kcal/kg) and isolysinic (0.75% SID Lys) by adjusting the inclusion of soybean meal, crystalline amino acids, and choice white grease. All other nutrient levels met or exceeded the NRC (2012) requirement estimates. There were 16 replicates per treatment. Pigs were weighed and feed disappearance measured to calculate ADG, ADFI, and G:F. Data was analyzed with SAS MIXED procedure. There was no evidence (P > 0.10) for interactive effects between L-Lys HCl and DDGS inclusion rate. Pigs fed diets with 10% DDGS had improved (P = 0.002) G:F, but there was no evidence (P > 0.10) for differences in ADG or ADFI. Pigs fed increasing levels of L-Lys HCl had higher (linear, P = 0.026) ADFI, decreased (quadratic, P = 0.013) G:F, and a tendency for quadratic response (P = 0.063) in ADG, overall with the poorest performance observed for pigs fed the diet with 0.4% L-Lys HCl. In conclusion, pigs fed 0 or 10% DDGS presented similar performance; however, pigs fed the high level of L-Lys HCl presented decreased performance.

Abstract Two experiments investigated the effects of feeding diets containing 30% of novel high-protein distillers dried grains (HP-DDG) sources to growing–finishing pigs on growth performance, carcass characteristics, and pork fat quality. A four-phase feeding program was used in both experiments, and diets within phases were formulated based on National Research Council (NRC; 2012) recommendations for metabolizable energy and standardized ileal digestible amino acid content of HP-DDG. In Exp. 1, a total of 144 pigs (body weight [BW] = 20.3 ± 1.6 kg) were fed either corn-soybean meal control diets (CON) or 30% HP-DDG diets (HP-DDG) containing 0.7 mg/kg deoxynivalenol (DON), 0.1 mg/kg fumonisins (FUM), and 56 μg/kg zearalenone (ZEA) for 8 wk. On week 9, a mycotoxin mitigation additive (MA) was added to CON and HP-DDG diets, resulting in a 2 × 2 factorial arrangement of treatments consisting of: CON, CON + MA, HP-DDG, and HP-DDG + MA. Pigs fed HP-DDG had lower (P < 0.01) average daily gain (ADG) and average daily feed intake (ADFI) compared with those fed CON during the first 8 wk. After MA was added to diets, pigs fed HP-DDG diets without MA had lower (P < 0.05) overall ADG than those fed HP-DDG + MA and less (P < 0.05) final BW than pigs fed CON or CON + MA. Adding MA to HP-DDG diets containing relatively low concentrations of mycotoxins was effective in restoring growth performance comparable to feeding CON. In Exp. 2, a different source of HP-DDG was used, and mycotoxin MAs were added to all diets at the beginning of the trial. A total of 144 pigs (BW = 22.7 ± 2.3 kg) were fed either a corn-soybean meal control diet or a 30% HP-DDG diet containing 0.5 mg/kg DON and 0.8 mg/kg FUM for 16 wk. Pigs fed HP-DDG diets had less (P < 0.01) final BW and ADG than pigs fed CON, but there were no differences in ADFI. Feeding the HP-DDG diets reduced (P < 0.01) hot carcass weight, carcass yield, longissimus muscle area (LMA), and percentage of carcass fat-free lean compared with pigs fed CON but did not affect backfat (BF) depth. Pigs fed HP-DDG had less (P < 0.01) saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) content and greater (P < 0.01) polyunsaturated fatty acid (PUFA) and iodine value in BF than pigs fed CON. These results suggest that feeding diets containing relatively low concentrations of co-occurring mycotoxins can be detrimental to growth performance, and the addition of MA alleviated the growth reduction. Feeding 30% HP-DDG reduced BW, ADG, carcass yield, LMA, and percentage of fat-free lean of growing–finishing pigs but yielded acceptable pork fat quality.

Abstract An experiment was conducted to determine the effects of added Zn source and level on growth performance and carcass characteristics of finishing pigs. A total of 1,980 pigs divided into 2 groups [group 1: 1,008 pigs, TR4 × (Fast Large White × PIC L02) and group 2: 972 pigs, PIC 337 × 1,050], initially 33.3 kg, were used in a 103- or 114-d growth trial in groups 1 and 2, respectively. Treatments were arranged in a 2 × 3 factorial with 2 sources of added Zn, Zn hydroxychloride (ZnHyd; IntelliBond Z, Micronutrients, Indianapolis, IN) or Zn sulfate (ZnSO4), and 3 levels of added Zn (50, 100, or 150 mg/kg). Diets contained a vitamin-trace mineral premix without added Zn and provided 76 and 162 mg/kg Fe and Cu, respectively. All diets contained 750 FTU/kg phytase. There was a total of 14 replicates per treatment. Pens of pigs were weighed approximately every 2 wk to determine average daily gain (ADG), average daily feed intake, and gain-to-feed ratio. At the end of the experiment, pigs were transported to a packing plant to determine hot carcass weight (HCW), backfat depth, loin depth, and lean percentage. Overall, there was no evidence (P > 0.10) for interactive effects of added Zn source and level for growth performance and carcass characteristics. Pigs fed diets with increasing added Zn had a tendency (P = 0.093) for a quadratic response in ADG, with the greatest ADG observed at 100 mg/kg added Zn. There was a linear improvement (P = 0.010) in carcass yield and a quadratic response (P = 0.045) in HCW, with pigs fed 100 mg/kg added Zn having the highest HCW. Pigs fed diets with ZnHyd had improved (P = 0.017) carcass yield and a tendency (P = 0.058) for greater HCW compared with pigs fed ZnSO4. In summary, under the commercial conditions of the study and with diets containing 750 FTU/kg phytase, there were relatively small improvements in ADG of growing-finishing pigs fed added Zn beyond 50 mg/kg. Providing higher levels of added Zn improved carcass characteristics. Zinc source did not influence growth performance, but ZnHyd improved carcass characteristics compared with ZnSO4.

Abstract Using alternative feedstuffs can be a feasible measure to reduce swine production cost. GuarPro F-71, a newly developed guar meal product, is considered as a potential protein source for pigs. This study was conducted to evaluate the effects of dietary GuarPro F-71 inclusion on growth performance and nutrient metabolism of growing pigs. Sixty crossbred barrows (31.9 ± 1.84 kg BW) were allotted to 5 dietary treatments according to a completely randomized experiment design with 4 pens/treatment and 3 pigs/pen. Diet 1 was a corn-and-soybean-meal based diet with nutrient composition following NRC (2012) recommendations. GuarPro-71 was used to replace 25%, 50%, 75%, and 100% of soybean meal (on equivalent CP basis) in Diet 1 to generate Diets 2, 3, 4, and 5, respectively. Crystalline amino acids were used to balance the essential amino acid concentrations across the 5 diets. Dietary inclusion of GuarPro-71 reduced ADFI (P < 0.01), whereas no clinical signs of unhealthiness of pigs were observed. The magnitude of ADFI reduction showed linear but also quadratic relationships (P < 0.05) with the GuarPro-71 inclusion rate. The blood plasma concentrations of six metabolites (urea nitrogen, total protein, albumin, glucose, total cholesterol, and total triglycerides) were not affected (P > 0.30), indicating that the pigs’ metabolic utilization of nutrients was not compromised. The cubic effect (P < 0.05) of dietary GuarPro-71 inclusion on the G:F suggests that the level of soybean meal replacement up to 75% by GuarPro-71 did not negatively affect feed efficiency in pigs. In short, the feed intake reduction due to the dietary GuarPro-71 inclusion should be, if not solely, responsible for the ADG and final BW reduction. Overall, this study suggests that the dietary inclusion of GuarPro-71 can negatively affect ADFI and ADG in growing pigs. The reason for the ADFI reduction warrants further investigation.

The Difference

ABSTRACT A total of 1,890 growing-finishing pigs (PIC; 359 × 1050; initially 27.1 kg) were used in a 124-d growth trial to compare the effects of high-protein distillers dried grains [HPDDG; 39% crude protein (CP)] or conventional distillers dried grains with solubles (DDGS; 29% CP) on growth performance and carcass characteristics. Treatments were arranged in a 2×2 + 1 factorial with main effects of distillers dried grains source (conventional DDGS or HPDDG) and level (15 or 30%). A corn-soybean meal-based diet served as the control and allowed linear and quadratic level effects to be determined within each distillers dried grains (DDG) source. All diets were formulated on an equal standardized ileal digestible (SID) Lys-basis with diets containing HPDDG having less soybean meal than diets with conventional DDGS. Pens were assigned to treatments in a randomized complete block design with initial weight as the blocking factor. There were 27 pigs per pen and 14 pens per treatment. Overall, increasing conventional DDGS decreased (linear, P &lt; 0.04) final body weight (BW), whereas increasing HPDDG tended to decrease (linear, P = 0.065) final BW. The decreased final BW was a result of decreased (linear, P &lt; 0.01) ADG in the grower phase of the study as either DDG source increased. However, there were no differences observed in the finisher phase or overall ADG between pigs fed either DDG source or either inclusion level. Pigs fed HPDDG had decreased (P &lt; 0.001) ADFI and increased (P &lt; 0.001) G:F compared with those fed conventional DDGS. For carcass traits, increasing either conventional DDGS or HPDDG decreased carcass yield and HCW (linear, P &lt; 0.02); however, there were no differences between pigs fed HPDDG or conventional DDGS. Iodine value (IV) increased (linear, P &lt; 0.02) with increasing DDG and was greater (P &lt; 0.001) in pigs fed HPDDG than conventional DDGS. In summary, pigs fed HPDDG had no evidence of difference in overall ADG compared to pigs fed conventional DDGS, but had greater overall G:F. Carcass fat IV was also greater in pigs fed HPDDG compared with pigs fed conventional DDGS. These differences were probably due to the difference in oil content.

Abstract Two experiments were conducted to determine the effects of increasing levels of soybean meal (SBM) replacing feed grade amino acids in corn or corn-dried distillers grains with solubles (DDGS)-based diets on growth performance of late finishing pigs. In both experiments, there were 22 to 27 pigs per pen and 14 pens per treatment. Average length of the experiments was 35 (Exp. 1) and 29 days (Exp. 2). Diets were balanced to contain 0.70% SID Lys and 2,667 or 2,610 kcal NE/kg for Exp. 1 and 2, respectively. Minimum amino acid ratios relative to Lys were: Ile, 55; Met&Cys, 60; Thr, 65; Trp, 19.5, and Val, 70. Dietary crude protein ranged from 10.1 to 15.2 for Exp. 1 and 13.6 to 19.4 for Exp. 2. The statistical model considered fixed effects of treatment, linear and quadratic contrasts, and random effect of block. In Exp.1, 1,793 pigs (L337×1050, PIC; initially 104.9 ± 1.4 kg) were fed corn-based diets and pens of pigs were assigned to 1 of 5 dietary treatments with increasing SBM from 5 to 20%. Overall, average daily gain (ADG) and gain-to-feed (G:F) increased (linear; P &lt; 0.05) as SBM increased with the greatest improvement observed as SBM increased from 5 to 8.75%, with little improvement thereafter. In Exp. 2, 1,827 pigs (L337×1050, PIC; initially 97.9 ± 1.1 kg) were used in a similar study as Exp. 1, but all diets contained 25% DDGS and SBM levels increased from 0 to 16%. Overall, G:F and final bodyweight of pigs marginally improved (linear and quadratic, respectively; P &lt; 0.10) as SBM increased, with the greatest performance observed when diets contained 8% SBM. These results suggest that increasing SBM up to 8% at the expense of feed grade amino acids in corn or corn-DDGS-based diets improved ADG or G:F in late-finishing pigs.

Abstract The objective of this study was to determine the interactive effects of dietary fiber source and lipid source on growth performance and visceral organ weights of weaned pigs. Two hundred and eighty 21 days old pigs [initial body weight (BW) = 6.84 kg] were housed in 40 pens (7 pigs/pen). The pigs were fed 4 diets (10 pens/diet) in a randomized complete block design in 2 phases, Phase 1 from day 0 to 14 and Phase 2 from day 14 to 35. The diets were corn-soybean meal-based with either sugar beet pulp (SBP) or soybean hulls (SBH) as fiber source and either soybean oil (SBO) or choice white grease (CWG) as fat source in 2 × 2 factorial arrangement. The BW and feed intake were determined by phase, whereas visceral organ weights were determined on day 35. Fiber source and fat source did not interact on growth performance and organ weights relative to BW. Pigs fed CWG-containing diets had lower (P &lt; 0.05) gain to feed ratio than those fed SBO-containing diets by 7.95% during Phase 1 of feeding. Pigs fed SBP-containing diets had lower (P &lt; 0.05) gain to feed ratio than those fed SBH-containing diets by 7.94% during Phase 1 of feeding. However, pigs fed SBP-containing diets had greater (P &lt; 0.05) stomach weight, and tended to have greater (P &lt; 0.1) heart, small intestine and large intestine weights relative to BW than those fed SBO-containing diets. In conclusion, replacement of SBH with SBP in diets for weaned pigs reduced feed efficiency and increased visceral organ weights relative to BW, implying that the replacement of SBH with SBP in diets of weaned pigs increased energy expenditure in visceral organs. Inclusion of SBO (at the expense of CWG) in diets for weaned pigs can improve feed efficiency.

Abstract Two experiments were conducted to determine the effects of soybean meal (SBM) level in diets with or without distillers dried grains with solubles (DDGS) on growth performance of late nursery pigs. A total of 1,064 and 1,011 pigs (PIC 280×1050; initially 10.5 ± 0.36 and 10.9 ± 0.22 kg) were used in Exp. 1 and 2, respectively, with 21 to 27 pigs per pen. Pens were assigned to treatments in a randomized complete block design with 7 replicates per treatment per experiment. Treatments 1 to 3 were diets with 23% DDGS and 21, 27, or 35% SBM. Treatments 4 and 5 were corn-SBM diets with 27 or 35% SBM. Diets were balanced to 1.30% standardized ileal digestible lysine and 2,606 kcal of net energy/kg. Data were analyzed with the GLIMMIX procedure of SAS with pen as the experimental unit and block as random effect. There was no evidence for treatment × experiment interactions, thus data from both trials were combined. Feeding diets with 23% DDGS decreased (P = 0.033) ADFI and improved (P = 0.033) G:F compared to corn-SBM diets, which may indicate underestimation of DDGS net energy. When analyzed as a factorial with or without DDGS, pigs fed diets with 35% SBM had a tendency (P = 0.052) for increased ADG and improved (P = 0.001) G:F compared with diets with pigs fed 27% SBM. As SBM increased from 21 to 35% in diets with DDGS, ADG (linear, P = 0.001) and G:F (quadratic, P = 0.007) improved. In summary, feeding diets with increasing SBM improved growth performance in late nursery pigs.

The objective of the study was to evaluate the effects of expanded diets on growth performance, meat quality, and carcass characteristics in finishing pigs. A total of 80 finishing pigs [(Landrace × Yorkshire) × Duroc] were randomly allotted to two dietary treatments: 1) unexpanded corn-soybean meal diets; 2) expanded corn-soybean meal diets. Each treatment consisted of ten replicate pens with four pigs (2 gilts and 2 barrows) per pen. There were no differences in daily feed intake and daily gain throughout the experiment (P less than 0.05). However, expanded diets decreased feed conversion ratio compared with unexpanded diets (P less than 0.05). Expanded diets had no effect on carcass characteristics and meat quality with the exception of increased sensory evaluation (color) of meat compared with unexpanded diets (P less than 0.05). In conclusion, expanded diets can improve feed conversion ratio but have no effect on daily gain and daily feed intake and sensory evaluation of meat color.
