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 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.

Ca:P Ratio

Abstract Our objective was to determine the effects of feeding different analyzed calcium to phosphorus (Ca:P) ratios on performance of growing-finishing pigs from 26 to 127-kg. A total of 1,134 barrows and gilts (PIC 359×Camborough, initial BW 26.3 ± 0.71 kg) were used in a 110-d growth trial with 27 pigs per pen and 7 pens per treatment in a randomized complete block design. The 6 dietary treatments were formulated to contain 0:75:1, 1.00:1, 1.25:1, 1.50:1, 1.75:1, and 2.00:1 analyzed Ca:P ratio. All diets were corn-soybean meal-based and were formulated to contain adequate standardized total tract digestible P (approximately 122% of NRC 2012 estimates) for the weight range in all 4 dietary phases. Treatments were achieved by increasing calcium carbonate at the expense of corn while maintaining a constant level of monocalcium phosphate. Experimental data were analyzed using generalized linear and nonlinear mixed models with pen as the experimental unit. Increasing analyzed Ca:P ratio increased (quadratic, P < 0.05) ADG, ADFI, and final BW. Feed efficiency (G:F) was relatively similar across analyzed Ca:P ratios of 0.75:1 to 1.75:1 but worsened (quadratic, P < 0.05) at the highest ratio of 2.00:1. Hot carcass weight (HCW) and carcass ADG increased (quadratic, P < 0.05) while carcass yield decreased (quadratic, P < 0.05) with increasing analyzed Ca:P ratio. Bone mineralization increased (quadratic, P < 0.05) with increasing analyzed Ca:P ratio. For ADG, ADFI, G:F, and bone ash, the quadratic polynomial model demonstrated the best fit. The maximum responses in ADG, ADFI, G:F, HCW, and bone ash were estimated at 1.38:1, 1.49:1, 1.29:1, 1.25:1, and 1.93:1 analyzed Ca:P ratio, respectively. In conclusion, for growing-finishing pigs from 26 to 127-kg fed diets adequate in STTD P, the analyzed Ca:P ratio to maximize growth performance and HCW criteria ranged from 1.25:1 to 1.49:1. A higher analyzed Ca:P ratio, estimated at 1.93:1, was required to maximize bone mineralization.

Abstract A total of 320 barrows (DNA 200×400, initially 11.3 ± 0.65 kg BW) were used in a 21-d growth trial evaluating the effects of feeding Trp biomass (CJ America-Bio, Downers Grove, IL) as a source of Trp on nursery pig performance. Pigs were weaned at approximately 21 d of age, placed in pens based on initial BW, and fed a common diet. On d 21 after weaning, pigs were weighed and pens were allotted to 1 of 4 dietary treatments with 5 pigs/pen and 16 replicates/treatment. Dietary treatments included a negative control (16% SID Trp:Lys), positive control (21% SID Trp:Lys from crystalline L-Trp), or diets containing Trp biomass to provide 21 or 23.5% SID Trp:Lys (included at 0.104 or 0.156% of the diet, respectively). Diets were corn-soybean meal based and contained 1.25% SID Lys with other AA set to meet or exceed NRC (2012) requirement estimates. The Trp biomass contained 69% Trp. Growth data were analyzed as a randomized complete block design using PROC GLIMMIX of SAS with pen as the experimental unit. Overall (d 0 to 21) pigs fed 21% Trp from L-Trp or Trp biomass had increased (P < 0.05) ADG compared to the control, with pigs fed the 23.5% SID Trp biomass intermediate. Pigs fed the 21% Trp from Trp biomass had improved (P < 0.05) G:F compared to the control with others intermediate. In conclusion, Trp biomass is a viable alternative to crystalline Trp, but further evaluation at higher inclusion levels is needed.

Standardized Ileal Digestible Lysine

Abstract Our objective was to determine the effects of feeding different neutral detergent fiber (NDF) and standardized ileal digestible (SID) lysine (Lys) levels on performance of growing-finishing pigs from 30- to 130-kg. A total of 2,016 barrows and gilts (PIC 280×Camborough, initial BW of 29.6±0.53 kg) were allotted to a randomized complete block design with a 2×2 factorial arrangement. Dietary treatments (Table 1) consisted with two NDF levels (13% or 20%) and two SID Lys curves (PIC2008 or PIC2016). There were 21 mixed-sex pigs per pen, and 24 pens per treatment. The experiment diets were fed in 3 phases. Wheat, wheat by-products, peas, and canola oil were used with NRC (2012) loading values to achieve treatments, and all diets were formulated to be iso-caloric (2,420 kcal NE/kg). Experimental data were analyzed using generalized linear mixed models with pen as the experimental unit. Increasing NDF level resulted in a reduction (P&lt; 0.05) in average daily gain (ADG), average daily feed intake, hot carcass weight, carcass yield, carcass ADG, and backfat depth (Table 2), and tended to decrease percentage of removals and mortality (P=0.10). Pigs fed PIC2016 Lys curve had greater ADG and carcass ADG as compared to those fed PIC2008 Lys curve (P&lt; 0.05). There were NDF×Lys interactions (P&lt; 0.10) for ADG, gain to feed ratio (G:F), carcass ADG, and carcass G:F. These response criteria were improved for pigs fed PIC2016 Lys curve compared to those fed PIC2008 Lys curve when NDF level was 13%; while no evidence of differences was observed at 20% NDF. Results indicate that increasing NDF level from 13 to 20% deteriorate performance of 30- to 130- kg pigs; and the improved growth performance of pigs fed PIC2016 Lys curve as compared to those fed PIC2008 Lys curve was only observed when lower NDF level was presented.

Abstract Our objective was to determine the effects of feeding different analyzed calcium to phosphorus (Ca:P) ratios on performance of growing-finishing pigs from 26 to 127-kg fed diets containing 1,000 phytase units (FYT). A total of 1,215 barrows and gilts (PIC 359×Camborough, initial BW 26 ± 0.71 kg) were used in a 114-d growth trial with 27 pigs/pen and 9 pens/treatment in a randomized complete block design. The 5 dietary treatments were formulated to contain 0:75:1, 1.00:1, 1.25:1, 1.50:1, and 2.00:1 analyzed Ca:P ratio. Diets contained 1,000 FYT of Ronozyme HiPhos 2500 (DSM Nutritional Products, Inc., Parsippany, NJ) with assumed release values of 0.15% available P and 0.132% standardized total tract digestible P (STTD P). All diets were corn-soybean meal-based and formulated to contain approximately 122% of NRC (2012) STTD P estimates for the weight range across all 4 dietary phases. Treatments were achieved by increasing calcium carbonate at the expense of corn while maintaining a constant level of monocalcium phosphate. Data were analyzed with pen as the experimental unit, using generalized linear and nonlinear mixed models which included quadratic polynomial, broken-line linear, and broken-line quadratic models. Increasing analyzed Ca:P ratio increased (quadratic, P < 0.05) ADG, final BW, and ADFI (quadratic, P < 0.10). Feed efficiency improved (linear, P < 0.05) with increasing analyzed Ca:P ratio up to 2.00:1. Hot carcass weight (HCW) increased (quadratic, P < 0.05) and carcass yield decreased (quadratic, P < 0.10) with increasing analyzed Ca:P ratio. Bone mineralization increased (quadratic, P < 0.05) with increasing analyzed Ca:P ratio. The maximum responses in ADG, G:F, HCW, and bone ash were estimated at 1.63:1, 1.05:1, 1.11:1, and 1.25:1 analyzed Ca:P ratio, respectively. In conclusion, the estimated analyzed Ca:P ratio requirement for growing-finishing pigs from 26 to 127-kg fed diets containing 1,000 FYT ranged from 1.05:1 to 1.63:1 to maximize growth rate, G:F, HCW, and bone mineralization.

Abstract The objectives of this experiment were to evaluate the effects of alternatives to antibiotic growth promoters (AGP), two group sizes, and their interaction on nursery pig performance to serve as a model for future AGP alternative studies. A 41-d experiment was conducted in a commercial wean-to-finish barn; 1,300 piglets weaned at 21 d of age (weaned 2 or 4 d prior to experiment; 6.14 ± 0.18 kg BW; PIC 1050 sows and multiple sire lines) were blocked by sire, sex, and weaning date, then assigned to eight treatments: four dietary treatments each evaluated across two group sizes. The four dietary treatments were: negative control (NC), positive control (PC; NC + in-feed antibiotics), zinc oxide plus a dietary acidifier (blend of fumaric, citric, lactic, and phosphoric acid) (ZA; NC + ZnO + acid), and a Bacillus-based direct-fed-microbial (DFM) plus resistant potato starch (RS) (DR; NC + DFM + RS). The two group sizes were 31 or 11 pigs/pen; floor space was modified so area/pig was equal between the group sizes (0.42 m2/pig). There were 7 pens/diet with 11 pigs/pen and 8 pens/diet with 31 pigs/pen. Data were analyzed as a randomized complete block design with pen as the experimental unit. Diagnostic assessment of oral fluids, serum, and tissue samples was used to characterize health status. Pigs experienced natural challenges of acute diarrhea and septicemia in week 1 and porcine reproductive and respiratory syndrome virus (PRRSV) in weeks 4–6. There was a significant interaction between diet and group size for ADG (P = 0.012). PC increased ADG in large and small groups (P &lt; 0.05) and ZA increased ADG only in large groups (P &lt; 0.05). Small groups had improved ADG compared to large groups when fed NC or DR diets (P &lt; 0.05). Similarly, PC increased ADFI (P &lt; 0.05). Compared to NC, ZA improved ADFI in large groups only (P &lt; 0.05; diet × group size: P = 0.015). Pigs fed PC had greater G:F than NC (P &lt; 0.05), and small groups had greater G:F than large groups (P &lt; 0.05). There was no effect of ZA or DR on G:F. Pigs fed PC required fewer individual medical treatments than NC and pigs fed ZA were intermediate (P = 0.024). More pigs were removed from large than small groups (P = 0.049), and there was no effect of diet on removals (P &gt; 0.10). In conclusion, careful study design, protocol implementation, sample collection, and recording of important information allowed us to characterize the health status of this group of pigs and determine treatment effects on growth performance and morbidity.

Two experiments were carried out to study the methodology of using increasing levels of substitution of the basal diet with fibrous test feedstuffs (sticky coffee hull - SCH) in digestibility trials with pigs. In Experiment 1, a digestibility trial was conducted using 30 crossbred barrows, allotted in a randomized block design. In Experiment 2, 42 growing and 42 finishing pigs were used, allotted in a completely randomized design, with six diets and seven replicates, with one animal per experimental unit. The six diets consisted of: a control diet, four diets using SCH ME values as obtained in Experiment 1 plus a diet using SCH ME value estimated by linear regression equation for 15% substitution. The digestibility study indicated that the use of increasing levels of substitution (7, 14, 21 and 28%) reduced SCH digestibility. ME values, as-fed basis, were 2,456, 2,377, 2,247 and 1,945kcal/kg. The overall results indicate that higher levels of substitution overestimate the energy value and that the method of increasing levels of substitution of the basal diet with feedstuffs test can be used to more accurately estimate the energy values of fibrous feedstuffs for pigs. For growing and finishing pigs respectively, up to 28% and 15% of sticky coffee hull can be used without impairing pig performance and economic feasibility.

Abstract The objective was to evaluate the effect of a blend of phytonutrients (Lean Fuel, LF) on performance of pigs in late finishing in a commercial research barn. A total of 590 DNA 600 Duroc finishing pigs (BW=75.7 + 1.0 kg) were blocked by weight and sex and allocated across two dietary treatments with 6 replications per treatment and 21 to 26 pigs per pen. Dietary treatments were: barrow (B) diets with and without LF and gilt (G) diets with and without LF. Diets were formulated to split-sex requirements (CON) for each period and LF diets were control diets + 0.125% LF. The experiment was 44-d where d 0 was 98-d post-wean. All data were analyzed using the MIXED procedure of SAS as a randomized complete block design as a 2 x 2 (diet x sex) factorial arrangement. Pen served as the experimental unit. Overall (d 0-44), the B gained more weight (P = 0.0282) and consumed more feed (P > 0.10) in ADFI. There was no diet x sex interaction (P > 0.10) for ADG. There was a tendency for an interaction (P = 0.0545) for ADFI, where LF B consumed more feed compared to CON B and CON G consumed more feed compared to LF G. There was an interaction for G:F (P = 0.0028) where G on LF had higher G:F compared to G on CON whereas G:F for B was not different to B on LF. In conclusion, LF improved ADG and G:F, but did so differently for G and B. http://www.conferenceharvester.com/

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 In a separate data set reported on the same trial (Coelho, 2018) reported that Natugrain TS changed the microbiome by breaking down arabinoxylans into smaller oligosaccharides, decreasing intestinal E. coli and intestinal lesion score. This study data set evaluated the effect of a NSPase enzyme, Natugrain TS, on pig performance and carcass characteristics. A total of 3,750 weaned pigs (28 kg), (PIC 337 x Camborough), were used in a randomized complete block design with pen as the experimental unit, treatment as the fixed effect, and block as the random effect (25 pigs/pen x 5 treatments x 30 replications). Pigs were blocked by sex and weight and fed mash corn/soy/DDGs diets formulated to meet or exceed current NRC (2012) recommendations. Treatments were T1= 0 g/MT Natugrain TS, T2= 100 g/MT Natugrain TS, T3= 150 g/MT Natugrain TS, T4= 200 g/MT Natugrain TS and T5= 250 g/MT Natugrain TS. At the finishing phase, Natugrain TS significantly increased ADG up to 200 g/ton (841, 842, 847, 854 and 852 g, P < 0.05, respectively), decreased FCR up to a dose level of 200 g/ton (2.77, 2.76, 2.74, 2.72 and 2.73, P < 0.05, respectively), increased carcass yield up to a dose level of 200 g/ton (70.2, 70.6, 71.2, 71.4 and 71.2, P < 0.05, respectively), increased percent lean up to a dose level of 200 g/ton (50.1, 50.7, 51.2, 52.4 and 52.1%, P < 0.05, respectively) and decreased mortality up to a dose level of 200 g/ton (4.8, 3.6, 2.7, 1.9 and 2.1%, P < 0.05, respectively). In conclusion, Natugrain TS at 150 to 200 g/ton increased pig performance, carcass charateristics and decreased mortality.
