Abstract This study evaluated the metabolizable (ME) release of graded levels of phytase when fed to 35 kg pigs on mash corn/soy diets formulated to meet or exceed current NRC (2012) recommendations. A total of 280 male (PIC 337 x Camborough) pigs 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 (4 pig/pen x 8 treatments x 10 replications). Pigs were blocked by sex and weight. Treatments groups consisted of PC, NC1=PC- 0.17% Ca, - 0.15% aP, -0.02% Na, -200 kcal/kg, T1=NC +1000 FTU/kg phytase+0.15 g/kg NSPase, T2=NC+1500 FTU/kg phytase+0.15 g/kg NSPase, T3=NC+2000 FTU/kg phytase+0.15 g/kg NSPase, T4=NC+2500 FTU/kg phytase+0.15 g/kg NSPase and T5=NC+3000 FTU/kg phytase +0.15 g/kg NSPase. TiO2 was used as the undigestible marker. Feed, rectum grabbed fecal samples were collected at 35 kg pigs. ME was 3407, 3213, 3301, 3329, 3345, 3354 and 3358 Kcal/kg, P < 0.05, respectively. The NC reduced the ME by 194 Kcal/kg versus the PC. 1000, 1500, 2000, 2500 and 3000 FTU/kg released 87, 116, 132, 141 and 145 Kcal/kg, respectively. Least cost formulation reduced net feed costs by $8.63, $9.22, $11.10, $11.90 and $12.39/ton, respectively. In conclusion, Natuphos E by breaking down phytic acid and Natugrain TS by breaking down NSPs released up to 145 Kcal/kg ME in pigs.

Abstract This study presents a novel find of a Feed NSPase Enzyme, Natugrain TS, reducing finish pig hemorrhagic bowel syndrome (HBS) mortality. 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 were 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 decreased intestinal E. coli log 10 (7.12, 4.95, 4.02, 3.21 and 3.25 log 10, P < 0.05, respectively), significantly decreased intestinal lesion score (0–5 score) (4.21, 4.02, 2.98, 2.25 and 2.26, P < 0.05, respectively). Microbiota was analyzed in fresh, manually collected, rectum fecal samples. Microbiota was separated into prevalent in Natugrain TS control (0) and 200 g/ton. In the control treatment, there was a prevalence of Desulfoyibrio, Oscillospira, Campylobacter, Anearoctruncus, Mogibacterium and Brachyspirae, etc., while in the 200 g/ton treatment there was a prevalence of Synergistales, Burkolderiales, Dehabacteriaceae, Bifidobacterium, Roseburia, Lactobacillus and Bacilli, etc. Natugrain TS significantly decreased mortality (4.8, 3.6, 2.7, 1.9 and 2.1 %, P < 0.05, respectively), significantly decreased specifically HBS mortality (3.50, 1.98, 0.68, 0.40 and 0.46%, P < 0.05, respectively). In conclusion, Natugrain TS changed the microbiome by breaking down arabinoxylans, decreasing intestinal E. coli and intestinal lesion score, changing the microbiota to prevalent Bifidobacterium, Roseburia, Lactobacillus and Bacilli, and Natugrain TS up to 200 g/ton specifically decreasing hemorrhagic bowel syndrome mortality from 3.5% to 0.5%.

Abstract This study examined the effect of 1-monoglycerides and 1,2-diglycerides of butyric-, caproic- and caprylic acid (SILOHealth™ 104L [monoglycerides]) and avilamycin on day 14 and 21 post weaning performance of E. coli (GN-Ent and O157:H7) day 5 challenged piglets fed corn/soy diets that met or exceeded current NRC (2012) recommendations. A total of 96, Choice Genetics CG32, piglets 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 (4 piglets/pen x 3 treatments x 8 replications). Pigs were blocked by sex and weight and were orally dosed with 5 ml (1x109 CFU/g, strain GN-Ent and O157:H7) E. coli d 5 after weaning (Ec). The treatment were: NC with Ec; T1=NC + 3 kg/MT monoglycerides; T2=NC+ 80 ppm avilamycin. Least significant difference was used to compare means of treatment. Mortalities and pen removals were weighed and recorded. The E. coli infection model was effective in causing E. coli mortality of 25% at d14 post weaning and 33% at d21 post weaning in NC. T1 and T2 reduced mortality versus NC at d14 (25, 3 and 0%, P < 0.05) and d21 (33, 4 and 0%, P < 0.05), increased ADG at d14 (203, 255 and 259 g, P < 0.05) and d21 (456, 511 and 515 g, P < 0.05), decreased FCR at d21 (1.90, 1.85 and 1.83, P < 0.05), and decreased intestinal E. coli, log 10 of CFU/g, versus NC (4.1, 2.2 and 2.1, P < 0.05). Monoglycerides and avilamycin performance, mortality and intestinal E. coli log 10 were not significantly different at P < 0.05. In conclusion, the use of monoglycerides improved ADG, reduced FCR, reduced mortality and reduced intestinal E. coli log 10 at day 14 and 21 post weaning versus NC and monoglycerides were not significant different (P < 0.05) than avilamycin.

Abstract There is a continued industry focus to decrease FCR (Pierozan, 2016), which means less feed per kg body tissue, and therefore vitamins need to be further concentrated in less and less feed to reach the same vitamin supplementation per kg of body tissue. A study was conducted to determine the response of pigs to different levels of vitamin supplementation based on the 2018 BASF Industry vitamin supplementation survey. Pigs were stressed to simulate commercial stress conditions. A total of 240 (PIC 337 x Camborough) pigs 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 (4 pigs/pen x 5 treatments x 12 replications). Pigs were blocked by sex and weight and fed corn/soy diets pelleted at 80C and formulated to meet or exceed current NRC (2012) recommendations. The stress imposed to simulate commercial conditions consisted of dirty floors, 1.65 m2/pig, on 7th day of trial, pigs were dosed with 1,000,000 E. Coli bacteria and 200,000 Salmonella bacteria. Treatments were NRC, low 25%, AVG, high 25% and high 5% vitamin supplementation. At finishing, vitamin supplementation increased ADG up to high 5% vitamin supplementation (750, 795, 831, 852, and 871 g, P < 0.05, respectively), improved FCR up to Hi 5% (3.21, 3.05, 2.91, 2.82 and 2.71, P < 0.05, respectively). Vitamin supplementation decreased finishing mortality up to high 5% vitamin supplementation (9.02, 7.43, 6.15, 4.81 and 4.02%, P < 0.05, respectively), improved lean cuts up to Hi 25% (57.5, 59.1, 60.5, 61.3 and 62.1, P < 0.05, respectively). The profit in $/kg pig and return on extra vitamin supplementation was from low 25 to AVG $0.1381/kg and 39x, respectively, from AVG to Hi25% was $0.0771/kg and 13X, and from Hi 25% to Hi 5% was $0.1259/kg and 38X.

Abstract The objective of this experiment was to evaluate the metabolizable energy (ME)-releasing efficacy of a 6-phytase, Natuphos E, on pig performance compared with fat. A total of 1750 weaned, (PIC 337 x Camborough) pigs 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 pig/rep x 7 treatments x 10 replications). Pigs were blocked by sex and weight. Treatments consisted of PC, NC1=PC- 0.17% Ca, - 0.15% aP, -80 Kcal/kg, NC2=PC- 0.17% Ca, - 0.15% aP, -100 Kcal/kg, NC3=PC- 0.17% Ca, - 0.15% aP, -120 Kcal/kg, NC1 + 1000, NC2 + 1750 and NC3 + 2500 FTU/kg. Pigs were fed mash corn/soy diets formulated to meet or exceed current NRC (2012) recommendations. Least significant difference was used to compare means of treatments. In phase 3, ADG was 655, 650, 642, 632, 697, 911 and 724 g, P < 0.05, respectively. FI was 968, 1000, 1004, 1010, 1028, 1023 and 1052,P < 0.05, respectively. FCR was 1.48, 1.54, 1.56, 1.60, 1.47, 1.44 and 1.45, P < 0.05, respectively. NC1, NC2 and NC3 decreased (P < 0.05) ADG and increased (P < 0.05) FCR compared to PC. NC1 + 1000, NC2 + 1750 and NC3 + 2500 FTU/kg Natuphos E, increased (P < 0.05) ADG, and decreased (P < 0.05) FCR compared to PC. ADG, FI and FCR of NC1 + 1000, NC2 + 1750 and NC3 + 2500 had a better performance (P < 0.05) than NC1, NC2 and NC3, respectively. In conclusion, 1000, 1750 and 2500 FTU/kg phytase, Natuphos E, met or exceeded (P < 0.05) the performance of 80, 100 and 120 Kcal/kg. 2500 FTU/kg Natuphos E phytase could compensate, performance wise, the reduction of 0.17% Ca, 0.15% aP and 120 Kcal/kg ME in the diet.

Abstract This study examined the effect of a phytase, Natuphos E, target dosing on pig performance and feed costs from wean to finish. A total of 240 (PIC 337 x Camborough), pigs 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 (6 pig/pen x 2 treatments x 20 replications). Pigs were blocked by sex and weight equalized and fed mash corn/soy diets formulated to meet or exceed the current NRC (2012) recommendations. Treatments consisted of PC, NC1 in phase 1 and 2=PC- 0.16% Ca, - 0.14% aP, -0.02% Na + 3000 FTU/kg phytase. NC2 in phase 3 and grow-fin= PC- 0.16% Ca, - 0.14% aP, -0.02% Na, -120 Kcal/kg + 2500 FTU/kg phytase. Phase 2 ADG was 396 and 457 g/d, P < 0.05, respectively, and FCR was 1.31 and 1.25, P < 0.05, respectively. Phase 3 (11-23kg) ADG was 638 and 644 g, P < 0.05, respectively, and FCR was 1.52 and 1.48, P < 0.05, respectively. Finishing phase (120 kg) ADG was 871 and 875 g, P < 0.05, respectively, and FCR was 3.02 and 2.98, P < 0.05, respectively. In phase 1 and 2, only P, Ca and Na were removed from the diet, allowing AA and ME released from phytic acid to go into performance, ADG increased by 15% and FCR improved by 6 points, P < 0.05. In conclusion, by removing P in phase 1 and 2 and adding 3000 FTU/kg phytase, ADG and FCR were significantly improved, and net feed cost was reduced by $1.33/ton. In phase 3 and grow-fin, P and ME savings and adding 2500 FTU/kg phytase reduced net cost by $11.00/ton feed, while maintaining the pig performance.

Abstract A total of 3,171 pigs (PIC 327×L42; initially 5.8 kg) were used in a 39-d study. Treatments were arranged in a 2 × 2 factorial with 0 or 1% cellulose (Arbocel, J. Rettenmaier USA, Schoolcraft, MI) and distillers dried grains with solubles (DDGS; 0 or 5% in phase 1 and 0 or 15% in phase 2). Dietary phases 1 and 2 were offered from d 0 to 10 and 10 to 25, respectively. From d 25 to 39, pigs received a common diet with 25% DDGS. Pens were blocked by weight and allotted to treatments in a randomized complete block design. Experimental unit was two pens (66 pigs) sharing a fence-line feeder with 12 replicates per treatment. Data were analyzed with the GLIMMIX procedure of SAS with block as random effect. From d 0 to 25 and d 0 to 39, there was an interaction (P < 0.05) between cellulose and DDGS for ADG. Pigs fed diets with both DDGS and cellulose had lower ADG than those fed diets without DDGS, with pigs fed diets with DDGS without the addition of cellulose being intermediate. From d 25 to 39, there was a tendency (P = 0.080) for an interaction for ADFI. Pigs previously fed diets without DDGS and with cellulose had higher ADFI than those fed diets with DDGS and cellulose, and pigs previously fed diets without cellulose had similar ADFI regardless of DDGS inclusion. There was a tendency for an interaction (P = 0.070) for pig removals. Adding cellulose to diets without DDGS numerically decreased pig removals, but the inclusion of cellulose to diets with DDGS resulted in increased pig removals. In summary, adding fiber to the diet as cellulose or DDGS resulted in a less pig removals; however, adding both cellulose and DDGS decreased ADG and ADFI.

Abstract An experiment was conducted with 430 sows to evaluate the ideal standardized ileal digestible (SID) Val:Lys on sow and litter performance during an 18.6-d lactation period. The SID Val:Lys ratios measured were based on the previously published literature and then values above and below reported values. Sows were randomly allotted within parity block (parity 1, parity 2, and parity 3+) to one of five corn–soybean meal-based lactation diets formulated to contain different levels of SID Val:Lys (0.50, 0.62, 0.75, 0.88, and 1.00, respectively). All diets were formulated to be isocaloric (3.35 ME Mcal/kg) with 0.95% SID Lys and contained vitamins and minerals that exceeded recommendations (NRC, 2012). Experimental diets were given to sows from 112 d of pregnancy throughout the 23-d lactation period. Litters were standardized within 48 h after farrowing. Sows were fed with the Howema computerized feeding system that mixed the high and low diets to create the intermediate diets, weighed the feed for each sow and then delivered the feed to each individual feeding hopper to record daily sow feed intake during lactation. Data were analyzed as a randomized complete block design using the PROC MIXED procedure of SAS with sow as the experimental unit and treatment as a fixed effect and parity as the random effect. Results were considered significant at P ≤ 0.05 and considered a trend at P > 0.05 and P ≤ 0.10. Sow ADFI was not significantly different (5.2, 5.2, 5.2, 5.0, and 5.4 ± 0.15 kg/d, respectively). On average, sows consumed ~45 g of SID Lys per day. Sow wean to estrus (5.2, 4.7, 5.3, 5.5, and 4.5 ± 0.32 d, respectively) was not different as the Val:Lys ratio changed. Increasing the Val:Lys ratio resulted in no differences (2.66, 2.64, 2.76, 2.61, and 2.62 ± 0.08 kg; P > 0.10) in average daily litter gain. There were no differences in sow weight loss or subsequent total born across the dietary treatments. Overall, increasing levels of SID Val:Lys did not change sow reproductive performance or piglet growth rate.

Abstract The objectives were to evaluate differences in productivity (mortality, number of pigs weaned and litter weights) and electricity usage between farrowing crates equipped with the HAVEN device or standard heat lamps. The HAVEN is a heat element designed to create a microclimate for newborn pigs. A total of 314 sows (Camborough; PIC, Hendersonville, TN) were initially allotted to the study in a randomized complete block design (RCBD) based on parity (P1, P2, P3+). Treatments consisted of control group (standard heat lamps) and treatment group (HAVEN device). Around d112 of gestation the sows were moved to the farrowing house and randomly allotted to the treatment. After farrow, litters were cross-fostered within treatment until 24-h after farrowing to equalize litter number to teat count. Litter size and weight were collected at the time of cross-fostering and at weaning. Sows had an ad libitum access to feed and water during lactation. Data were analyzed as an RCBD using the GLIMMIX procedure of SAS with litter as the experimental unit and block as a random effect. There was no significant difference (P &gt; 0.05) between treatments on litter growth performance. However, there were significant differences (P &lt; 0.05) between the Control and Haven groups on piglets mortality and removals (%). The Control group had a higher incidence of mortality when compared to the Haven group (11.42% vs. 9.06%, respectively). In addition, the Control group had a higher (P &lt; 0.05) percentage of pigs removed compared to the Haven group (18.41% vs. 15.55%, respectively). Regarding electricity usage, on average the HAVEN device consumed 1.55 Wh/day compared to 2.41 Wh/day from the heat lamp. In conclusion, under the conditions of this trial the HAVEN provided production benefits reducing mortality and removals (%), and also potential savings in electricity.

Abstract The objective was to evaluate the effect of IFTA NBS on productive performance in pigs from nursery until the end of 1st grow-finish phase. Total of 1,200 pigs (PIC 337 x 1050; PIC, Hendersonville, TN) were allotted in a randomized complete block design (RCBD) and assigned to blocks based on weight and sex, random allocated to pens with 25 pigs/pen. Diet changes occurred in 4 phases: N1 lasting 7 days, N2 14 days, N3 21 days and F1 21 days. Animals were random assigned to 4 treatments: T1) zinc oxide (ZnO) during N1 (3000 ppm) and N2 (2500 ppm) with no antibiotics; T2) carbadox at 50 g/ton in N1 and N2; T3) IFTA NBS at 500 g/ton during N1, N2 and N3; and T4) IFTA NBS at 500 g/ton during N1, N2 and N3 along with ZnO in N1 (3000 ppm) and N2 (2500 ppm). Treatments were fed a common diet during F1. Outcomes were analyzed as RCBD using SAS PROC GLIMMIX with pen as experimental unit, treatment as main effect and block as random effect. There were significant differences (P &lt; 0.05) in weights and average daily gain (ADG) between T2 and T3 during N2. Significant differences on average daily feed intake (ADFI) were observed between T1 and T2 vs. T3 during N2, and between T2 and T3 during N3. During nursery period (N1-N3), ADG and ADFI were different (P &lt; 0.05) between T2 and T3. By the end of the trial, a significant difference in gain:feed between T2 and T3 was detected. Under the conditions of this study, IFTA NBS in combination with ZnO could replace carbadox as it obtained similar weight and FCR during nursery. In addition, the response on gain:feed during the first grow-finish phase deserves further investigation since suggests a beneficial residual effect of IFTA NBS.

Abstract This study examined the effect of 1-monoglycerides and 1,2-diglycerides of butyric-, caproic- and caprylic acid (SILOHealth™ 104L [monoglycerides]), 2.5*105 CFU/g, Clostridium butyricum probiotic (probiotic) and avilamycin on grow-fin performance of day 5 Salmonella (S. enterica) challenged pigs fed corn/soy diets formulated to meet or exceed current NRC (2012) recommendations. A total of 96, Choice Genetics CG32, male pigs 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 (3 pig/pen x 4 treatments x 8 replications). Pigs were orally dosed with 5x105 CFU/g, Salmonella enterica at day 5 (Se) of trial start. The treatment groups were: NC= Se; T1=NC + 80 ppm avilamycin. T2=NC+ 3 kg/MT monoglycerides, T3=NC+ 5 kg/MT monoglycerides, T4= 0.5 kg/MT probiotic and T5= 1.0 kg/MT probiotic. P < 0.05 was used to determine the level of significance. Least significant difference was used to compare means of treatment groups. T1, T2, T3, T4 and T5 increased ADG versus NC at d28 (663, 868, 738, 834, 718 and 798 g, P < 0.05) and d77 (910, 1093, 1032, 1073, 966 and 1004 g, P < 0.05), decreased FCR at d77 (2.84, 2.73, 2.81, 2.75, 2.81 and 2.74, P < 0.05), and decreased fecal Salmonella, log 10 of CFU/g, at d77 (3.64, 2.13, 2.89, 2.66, 2.99 and 2.69, P < 0.05). Five kg of monoglycerides and 1.0 kg of probiotic performance, mortality and fecal Salmonella, log 10, were not significantly different than avilamycin at P < 0.05. In conclusion, the use of 1-monoglycerides and 1,2-diglycerides of butyric-, caproic- and caprylic acid and clostridium butyricum probiotic improved ADG, reduced FCR and reduced fecal Salmonella, log 10, at day 70 and were not significant different (P < 0.05) than avilamycin.
