Book excerpt: Three experiments were conducted to determine the influence of dietary strategies on nursery pig performance. In Exp. 1, a total of 2,592 pigs were used to determine the effects of two antibiotics (chlortetracycline; CTC vs. tiamulin) and their route of administration (in-feed vs. in-water) on nursery pig growth performance. Although antibiotics did not improve feed efficiency when compared to non-medicated fed pigs, providing CTC in feed with or without tiamulin or tiamulin provided in the water improved nursery pig growth performance. In Exp. 2, 360 weaned pigs were used to evaluate potential replacements for pharmacological levels of Zn (provided by Zn oxide), such as diet acidification (sodium diformate), and dietary crude protein (CP: 21 vs. 18%) on nursery pig performance and fecal dry matter. Although none of the diets had a major influence on fecal dry matter, the addition of pharmacological levels of Zn or sodium diformate independently improved nursery pig performance. In Exp. 3, 1,215 pigs were used to determine the effect of AviPlus, a combination of micro-encapsulated sorbic and citric acids and synthetic thymol and vanillin botanicals, (Vetagro, Inc. Chicago, IL) on growth performance of pigs from weaning to market. When AviPlus was provided during the nursery phase, there was an improvement in G:F in the early and overall nursery phases, but there was no effect on overall wean-to-finish performance.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments evaluated the effects of feeding growth promoting alternatives, alone or in combination, on nursery pig performance in comparison to a common feed additive, carbadox. In Exp. 1, 288 weaned pigs (Line 600 × 241; DNA, 5.36 kg) were used in a 42-d study. Pigs were allotted to 1 of 9 dietary treatments in pens of 4 at weaning in a randomized complete block design with 8 replications per treatment. Dietary treatments were arranged with a negative control diet with no dietary feed additive, a positive control with added carbadox or 7 treatments including added copper sulfate (CuSO4; 0 vs. 125 ppm Cu) and added zinc oxide (ZnO; 0 vs. 3,000 ppm Zn from d 0 to 7 and 2,000 ppm Zn from d 7 to 28), essential oils from XTRACT 6930 at 0.91 kg/ton, Safman (yeast cell walls) at 0.23 kg/ton, Biosaf HR (yeast cells) at 0.68 kg/ton. These supplements were fed alone or in combination. From d 0 to 7 experimental diets were a pelleted diet and fed in a meal form from d 7 to 28, followed by a common corn-soybean meal-based diet from d 28 to 42. Essential oil blend (cinnamaldehyde) and yeast had no (P> 0.05) effect on ADG. Feeding carbadox or added trace minerals (Cu and Zn) improved ADG (P 0.05) of nursery pigs compared to the control. Carryover effects from any of these dietary treatments on subsequent growth performance were not (P 0.05) different. The use of added trace minerals Cu and Zn alone or in conjunction with either yeast or essential oil blend (cinnamaldehyde) results in ADG and G/F comparable to carbadox. In Exp. 2, 280 weaned pigs (Line 600 × 241; DNA, 5.18 kg) were used in a 35-d study. Pigs were allotted to 1 of 7 dietary treatments in pens of 5 at weaning in a randomized complete block design with 8 replications per treatment. Dietary treatments were arranged with a negative control diet with no dietary feed additive, a positive control with added carbadox or 5 treatments including added copper sulfate (CuSO4; 0 vs. 125 ppm Cu) and added zinc oxide (ZnO; 0 vs. 3,000 ppm Zn from d 0 to 7 and 2,000 ppm Zn from d 7 to 35), and Victus® LIV (145 or 435 ppm). These supplements were fed alone or in combination (Cu/Zn and 145 ppm Victus® LIV or Cu/Zn and 435 ppm Victus® LIV. Diets were fed in meal form. Feeding carbadox, 145 ppm Victus® LIV or added trace minerals (Cu and Zn) improved ADG (P 0.05) of nursery pigs compared to the control. In summary, under the conditions of these experiments, pigs fed zinc/copper, 145 ppm Victus® LIV or a combination of these had similar (P 0.05) growth performance to pigs fed carbadox.

This book was released on 2020 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: To secure animal welfare and maximum production, feed additives are often added to nursery pig diets to increase nutrition digestibility, enhance intestinal health, and prevent or mitigate disease, with the ultimate goal of improving growth performance. This thesis performed a longitudinal analysis using next-generation sequencing to investigate the dynamic changes of gut microbiota in weaned pigs fed commercial feed additives. Chapter II was used to evaluate the effects of organic acid mixture on growth performance and gut microbiota of weaning pigs. This study demonstrated that the inclusion of 0.035% (SBA0.035) or 0.070% (SBA0.070) sodium butyrate in a diet containing 0.5% benzoic acid improved the growth performance of weaning pigs. The SBA0.035 diet revealed the greatest gut microbial diversity and the enrichment of several potentially beneficial bacterial taxa such as Oscillospira, Blautia, and Turicibacter. The results showed that the gut community benefitted more in pigs fed this diet compared to the other diets used in this study. Chapter III evaluated the impact of peptides along with probiotic and ZnO on the growth performance and fecal microbiome of weaning pigs. Results indicated that the combination diet of peptides and ZnO can offer equivalent growth performance but at a lower cost as compared to the diet containing SDPP and ZnO. Gut microbiota analysis clearly showed that diet containing peptides plus ZnO had similar impacts on specific bacteria as dietary SDPP in combination with ZnO, which may have contributed to increased growth performance. In Chapter IV, we evaluated the growth performance and gut microbiota of weaning pigs subjected to different levels of peptides with or without the pharmaceutical level of ZnO supplementation in a nutrient‐deficient diet. Results revealed that the pharmaceutical level of ZnO conditioned the gut community to a point where the peptides could effectively restore growth performance in nursery pigs fed nutrient-deficient diets.

Book excerpt: Four studies were conducted to evaluate methods to nutritionally improve nursery pig or meat goat growth and efficiency. In Exp. 1, a total of 360 weanling pigs (DNA 200 x 400; 5.4 ± 0.07 kg BW) were fed for 35 days, with 6 pigs/pen and 10 replicate pens/treatment. Pigs were allotted based on BW in a completely randomized design to treatment diets: 1) Negative control; 2) Control + 3,000 ppm ZnO in phase 1 and 2,000 ppm ZnO in phase 2; 3) Control + 50 g/ton carbadox; 4) Control + C6:C8:C10 MCFA blend; 5) Control + Proprietary Oil Blend (Feed Energy Corp.); 6) Control + monolaurate blend (FORMI GML from ADDCON). Treatments were fed through two dietary phases and a common diet fed through phase three. Pigs and feeders were individually weighed on a weekly basis to determine average daily gain (ADG) and average daily feed intake (ADFI). From d 0 to 19, pigs being fed the ZnO or Carbadox diets had the greatest ADG. These pigs had significantly higher (P 0.05) ADG than pigs fed the control or Feed Energy Proprietary Oil Blend, while pigs fed the C6:C8:C10 blend or FORMI GML diets had similar (P 0.05) ADG compared to those fed carbadox. Overall, these results show that ZnO and carbadox are valuable additives to help maximize growth performance in early stages of the nursery. Some MCFA products may result in similar performance while others restrict it. Next, a total of 360 weanling pigs (DNA 200 x 400; initially 9.7 ± 0.23 kg BW) were used in a 21-d experiment with 6 pigs/pen and 10 replicate pens/treatment. Pigs were allotted to pens based on BW in a completely randomized block design to one of 6 diets: 1) Negative control (no organic acids or antibiotics); 2) Control + 0.25% Commercial Acidifier A) Control + 0.3% Commercial Acidifier B; 4) Control + 0.5% Commercial Acidifier C); 5) Control + 50 g/ton Carbadox; 6) Control + 400 g/ton Chlortetracycline). Dietary treatment had a significant impact (P 0.05) on ADG, ADFI and G:F for the entire experiment. Carbadox negatively impacted ADG and ADFI (P 0.0001), while pigs fed CTC had improved (P

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments using a total of 720 nursery pigs were used to determine the effects of Elarom SES, in-feed antibiotics, zinc, or copper on nursery pig growth performance and fecal consistency. Two experiments using a total of 1,534 nursery pigs were used to determine the effects of formaldehyde inclusion, lysine level, and synthetic amino acid inclusion on nursery pig performance, amino acid utilization, and gut microbial community. One experiment using a total of 300 nursery pigs were used to determine the effects of chlortetracycline (CTC) or a probiotic inclusion on nursery pig growth performance and antimicrobial susceptibility. Experiment 1 determined the effect of Elarom SES, in-feed antibiotics, or zinc on nursery pig performance and fecal consistency. The addition of Elarom SES or ZnO alone reduced ADG, but G:F was poorest when all three additives were fed in combination. Addition of in-feed antibiotics increased ADG and G:F throughout the study. Experiment 2 determined the effects of Elarom SES or copper inclusion on nursery pig performance and fecal consistency. The addition of Elarom SES or increasing copper did not provide consistent benefits in performance. In both experiments, there were no individual or overall treatment effects or treatment × day interactions observed for fecal consistency. Experiment 3 compared the effects of formaldehyde source and lysine level on nursery pig growth performance. Regardless of source or lys level, the inclusion of formaldehyde in nursery pig diets marginally reduced ADG and resulted in poorer G:F. Experiment 4 compared the effects of formaldehyde and synthetic amino acid inclusion level on nursery pig growth performance, amino acid utilization, and gut microbial community. The inclusion of Sal CURB in diets reduced ADG and ending BW while inclusion decreased ADFI. ADFI response was dependent on synthetic amino acid level in the diet. Sal CURB inclusion in diets reduced total and available lysine, but reduced bacterial microflora in treatment feed. Experiment 5 determined the effects of CTC or a probiotic on nursery pig performance and antimicrobial susceptibility. The addition of CTC to diets improved ADG, ADFI, and ending BW. The addition of Poultry Star improved ADFI and d 14 BW, but benefits did not carry throughout the study.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 6 experiments, a total of 1,802 pigs were used to determine: 1) effects of increasing crystalline amino acids in sorghum- or corn-based diets on nursery or finishing pig growth performance; 2) effects of different Zn sources on nursery pig performance; and 3) effects of different corn oil sources on nursery pig performance. In the first set of experiments, corn or sorghum-based diets were supplemented with increasing levels of synthetic amino acids up to the 5[superscript]th limiting amino acid. For nursery pigs, there were no main or interactive effects (P>0.05) of grain source or added amino acids which suggests that balancing up to the fifth limiting amino acid is possible in both sorghum- and corn-based diets with the use of crystalline amino acids without detrimental effects on nursery pig growth performance. For finishing pigs, balancing to the 5[superscript]th limiting AA using NRC (2012) suggested amino acid ratios in corn- or sorghum-based diets resulted in decreased ADG and G:F and pigs fed corn-based diets had greater G:F and IV than those fed sorghum. The second set of studies compared two new zinc sources to a diet containing pharmacological levels of ZnO on nursery pig growth performance. These studies demonstrated that increasing Zn up to 3,000 ppm Zn increased ADG and ADFI. Lower levels of the new zinc sources did not elicit similar growth performance as the high level of ZnO. The third set of studies compared increasing levels of different sources of corn oil to diets containing soy oil. In the first study, an oil source × level interaction was observed (P

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted to determine the effect of crude protein level in diets containing coarse wheat bran with or without pharmacological levels of Zn (provided by zinc oxide: ZnO) on growth performance and fecal dry matter of swine (n = 360 or n = 650 pigs for experiment 1 and 2, respectively). A third experiment used 360 nursery pigs to evaluate the effects of insoluble fiber source and crude protein level on growth performance and fecal dry matter. Experiment 4 used 109 sows to evaluate the effect of increasing units of Ronozyme HiPhos phytase in lactation diets on sow and litter performance. In Exp. 1, pigs fed pharmacological levels of Zn had improved growth performance. However, increased performance was not observed for pigs fed high levels of Zn in Exp. 2. Reducing crude protein and subsequently SID Lys in diets with coarse wheat bran in an attempt to reduce the occurrence of post-weaning diarrhea did improve fecal dry matter but did not maintain or improve growth performance. Pigs fed diets supplemented with high levels of feed grade essential amino acids did not have improved growth. Improvements in feed efficiency were observed for pigs with the addition of non-essential amino acids to diets containing coarse wheat bran. In Exp. 3, reducing crude protein level resulted in decreased growth performance while fecal dry matter was increased on day 17. The source or inclusion of dietary insoluble fiber had no effect on growth performance, while the inclusion of cellulose as a fiber source improved fecal dry matter. For Exp. 4, increasing phytase from 0 to 3,000 FYT/kg increased feed intake in late lactation and overall intake tended to increase. Linear improvements in pig survivability were observed with increasing phytase. Overall litter gain and weaning weight was maximized for sows fed 1,000 FYT/kg.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 3 chapters of this thesis involve 1) an evaluation of fermented corn protein and its effects in either high or low branch chain amino acid to leucine ratio diets on nursery pig performance and feed intake preference, 2) an evaluation of the acid-binding capacity of ingredients and complete diets commonly used for weanling pigs, and 3) the influence of anchovy fish meal compared to other protein sources on nursery pig performance. Chapter 1 consisted of 3 experiments which used 880 weaned pigs to evaluate fermented corn protein's effect on nursery pigs. In Exp. 1, fermented corn protein was evaluated as a potential replacement to enzymatically treated soybean meal. In Exp. 2, pigs were fed increasing levels of fermented corn protein with either low or high branch chain amino acid to leucine ratios. In Exp. 3, fermented corn protein and its components were evaluated to measure nursery pig feed intake preference. Results from the studies suggest that fermented corn protein decreases nursery pig performance and increasing branch amino acid to leucine ratio only improves feed efficiency, however, whole stillage solids appear to be the component of fermented corn protein that negatively affect feed intake preference. Chapter 2 measured the acid-binding capacity of common nursery pig feed ingredients and evaluated acid-binding capacity additivity in complete diets. The results of this study suggest a low acid-binding capacity diets can be successfully formulated through careful selection of ingredients. Ingredients, with the exception of calcium carbonate and zinc oxide, appear to be additive in complete diets. Calcium carbonate and zinc oxide's acid-binding capacity contribution in complete diets did not match its value from ingredient analysis. Chapter 3 consisted of two experiments which used 2,502 weaned pigs to determine the influence of anchovy fish meal compared to other protein sources on nursery pig performance. In both experiments, pigs were fed diets containing one of six vegetable or animal protein sources with Exp. 2 being held in a commercial environment. Protein sources included enzymatically treated soybean meal, spray-dried bovine plasma, fermented soybean meal with or without fish solubles, fish meal with or without fish solubles. In Exp. 1, fish meal with solubles and spray-dried bovine plasma resulted in a 5 to 7% improvement in average daily gain, although results were not significant. However, in Exp. 2, pigs fed fish meal with solubles had decreased growth performance compared to other protein sources.

This book was released on 2006 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to: (1) quantify the effect of piglet birth weight on weaning and nursery off-test weights, (2) assess the effect of weaning age on nursery pig performance, and (3) model the effect of weaning age on subsequent sow reproductive performance. The study utilized Danbred N.A. (Columbus, NE) barrows and gilts (n=2,467) from a commercial maternal line multiplication herd. Litters were randomly assigned at birth to either a 15 d (pigs weaned at 14, 15, and 16 d of age) or a 20 d (pigs weaned at 19, 20, and 21 d of age) average weaning age group. Increasing birth weight from 0.94 to 2.06 kg improved subsequent growth performance. Collectively, birth weight and weaning weight are important predictors of subsequent nursery growth performance. The research also defined how weaning age affects ADG, ADFI, mortality %, G:F, and feed cost/kg gain in the nursery phase of production. Pigs weaned at 20 d had greater ADG, increased ADFI, fewer pigs removed from the test, similar G:F ratios, and lower feed cost/kg gain when compared to pigs weaned at 15 d. Pigs in the 20 d weaning age group were also heavier at the end of the 42 d nursery phase of production when compared to pigs weaned in the 15 d group. Based on the differences seen in pigs weaned at 20 d and 15 d, weaning pigs at 20 d may prove advantageous in commercial operations because of the improvements in nursery growth performance. The research also analyzed the effect of lactation length on wean-to-estrus interval (WSI), wean-to-conception interval (WCI), and subsequent litter size in sows weaned at two different average weaning ages. No significant lactation length treatment differences were observed for WSI, WCI, or subsequent litter size. This study indicates that producers should be able to choose weaning ages in the range of 15 to 20 d without any negative impacts on sow reproductive performance. Thus, when producers are making weaning age decisions they must consider what the best decision is for the entire production system.

Book excerpt: In 3 experiments, 4,720 pigs were used to determine the effects of: 1) dietary fat and feeding duration on growth performance and fat quality in finishing pigs; or 2) a novel protease or 3) increasing levels of Zn amino acid complex (ZnAA) or ZnO on finishing pig performance. Experiment 1 tested the effects of feeding tallow, soybean oil, or a blend of the two for various feeding durations (d 0 to 42, 42 to 84, or 0 to 84). Overall, pigs fed added fat for the entire 84 d had improved G:F compared to those fed a control diet. Additionally, pigs fed additional fat for the entire study had improved ADG and G:F as well as increased d 84 BW compared to pigs fed additional fat for 42 d. Increasing the feeding duration of soybean oil lowered monounsaturated fatty acids and increased polyunsaturated fatty acid concentrations while these values remained relatively unchanged by the addition of tallow. There were feeding period by fat source interactions for fatty acid composition and iodine value for belly and backfat, but not jowl fat, indicating a longer turnover rate for jowl fat compared to belly or backfat. In Exp. 2, adding a protease to a nutrient deficient diet increased ADFI and tended to increase ADG compared to pigs fed a negative control diet. There were no differences observed in ADG, ADFI, or G:F between pigs fed a positive control diet, formulated to 90% of the pigs SID lysine requirement, and those fed a negative control diet plus the protease, which would suggest the release values attributed to the enzyme were accurate. In Exp. 3, supplementing additional Zn from either ZnAA or ZnO at 25, 50, or 75 ppm in finishing diets for commercial finishing pigs was evaluated. Overall, no differences were observed in ADFI, but a Zn source by level interaction was observed for ADG and G:F, as pigs fed increasing ZnO were observed to have similar performance, while pigs fed added levels of 25 and 50 ppm Zn from ZnAA had decreased performance compared to those fed the highest level of ZnAA.

Warner and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 3 chapters of this thesis involve 1) effects of added calcium carbonate with and without benzoic acid on weanling pig growth performance, fecal dry matter, and blood Ca and P concentrations, 2) evaluation of different corn protein sources on nursery pig growth performance and fecal dry matter, and 3) evaluation of a dried fermentation product administered through drinking water on nursery pig growth performance, fecal E. coli characterization, antibiotic usage, and mortality. Chapter 1 utilized 1,055 pigs in two experiments. In Exp. 1, 695 pigs were used in two groups to evaluate increasing calcium carbonate (CaCO3) levels from 0 to 1.80%. Experiment 2 utilized 350 pigs to investigate the interactive effects between CaCO3 and benzoic acid. In Exp. 2, CaCO3 was included at 0.45, 0.90, and 1.35% with and without 0.50% inclusion of benzoic acid. In both experiments, increasing CaCO3 in the diet decreased G:F. In Exp. 2, there was no evidence for CaCO3 x benzoic acid interactions, but providing benzoic acid improved ADG, ADFI, and tended to improve G:F. As well, the level CaCO3 was directly reflective of serum Ca; as CaCO3 decreased in the diet, so did serum Ca. Chapter 2 involved 670 nursery pigs in two experiments to investigate corn co-products as replacements to specialty protein sources in the swine industry. Experiment 1 utilized 315 pigs and observed decreased growth performance when feeding 5 or 10% of corn protein sources. The second experiment utilized 355 pigs and observed that a fourth corn protein source did not influence growth performance compared to a control. Increasing this fourth corn protein source increased daily gain and feed intake, with intermediate inclusion levels having the greatest ADG and ADFI. Gain-to-feed decreased linearly with increasing this fourth corn protein. Finally, chapter 3 utilized 34,749 pigs in two experiments to evaluate a dried fermentation product administered through drinking water on nursery pig growth performance, fecal E. coli characterization, antibiotic usage, and mortality. Experiment 1 was conducted in a research setting utilizing 350 nursery pigs, where the dried fermentation product did not influence growth, antibiotic usage, fecal consistency, or E. coli presence. Experiment 2 was conducted in commercial nurseries utilizing 34,399 nursery pigs, where providing the dried fermentation product did not influence growth performance, reduced antibiotic injections, but increased nursery mortality.

Several approaches to maximize resource utilization in swine production were evaluated including dietary approaches and interventions within the feed manufacturing process to optimize animal health. A total of 7,842 pigs were used over a total of 10 experiments structured in 6 chapters. Chapter 1 evaluated the effects of roller mill configuration on growth performance of nursery and finishing pigs, feed preference, and feed mill throughput. The four experimental treatments included corn ground through a roller mill using two, three, four sets of rolls in a fine-grind configuration, or four sets of rolls in a coarse grind configuration. There was no evidence of differences observed for average daily gain (ADG) or average daily feed intake (ADFI) between roller mill configurations when fed to nursery pigs. However, when given a choice nursery pigs consumed more of the diet containing corn ground through the 2-high roller mill or 4-high coarse configuration compared to corn ground through the 4-high fine configuration. Finally, finishing pigs fed corn ground with the 2-high configuration had greater ADG compared to those fed corn ground using the 3-high configuration. Grinding rate was greatest for the 4-high coarse configuration, while net electricity consumption was lowest for the 2-high configuration and greatest for the 4-high fine configuration. Chapter 2 evaluated the impact of commercial feed additives on the quantification of genetic material and infectivity of swine feed inoculated with porcine epidemic diarrhea virus (PEDV). The combination of essential oils and benzoic acid enhanced degradation of PEDV ribonucleic acid (RNA) in feed but had little impact in spray-dried porcine plasma. In addition, differences in viral stability was observed between feed and spray-dried porcine plasma where PEDV could be detected and remained infectious longer compared to swine feed. Chapter 3 evaluated the impact of flushing feed manufacturing equipment with rice hull flushes following mixing PEDV infected feed. Flushing effectively reduced the quantity of detectible RNA present after mixing a batch of PEDV-positive feed. Furthermore, chemical treatment of rice hulls with formaldehyde or 10% medium chain fatty acid (MCFA) provided additional reduction in RNA detection. Chapters 4 and 5 evaluated the inclusion of added chromium (Cr) in finishing diets. In chapter 4, small differences in ADG and feed efficiency were observed with added Cr. In chapter 5, adding Cr along with Yucca schidigera led to modest changes in performance with the greatest benefit observed with 200 [mu]g/kg Cr and 125 mg/kg Yucca schidigera-based feed grade concentrate. Chapter 6 evaluated the impact of feeding MCFA to nursery pigs and demonstrated improved growth performance, but did not significantly alter fecal microbial composition, and provided residual mitigation activity when inoculated with PEDV following feed storage. Overall, evaluation of feed manufacturing technologies and various feed additives demonstrates potential to have a significant impact on the efficiency of swine production. Additionally, understanding the role that feed and feed transportation contributes to health of swine populations is critical for maintaining a high health and productive global swine industry.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirteen experiments using a total of 7,589 nursery and finishing pigs were conducted to evaluate the effects of deoxynivalenol (DON), feed additives and processing conditions on nursery pig growth performance. In addition, feed withdrawal and diet blending were evaluated in finishing pigs. Experiment 1 tested 3 feed additives in DON-contaminated diets with only Defusion Plus improving performance. Experiment 2 evaluated Biofix in both low- and high-DON diets and showed no effects on growth. Experiments 3 and 4 further evaluated levels of Defusion and the effects of pelleting and supplemental nutrients in DON-contaminated diets. Defusion improved growth in low-DON diets, but had variable effects in high DON diets. Pelleting DON-contaminated diets resulted in comparable growth to pigs fed positive control diets in meal form. In Exp. 5 and 6, pilot studies evaluated DON-detoxification using sodium metabisulfite (SMB) with hydrothermal treatment in both an autoclave and a pellet mill. These conditions reduced analyzed DON by as much as 89 and 75% for the autoclave and pellet mill, respectively. In Exp. 7 and 8, pelleting DON-contaminated diets with SMB improved growth. Experiments 9 and 10 evaluated feed-withdrawal time on carcass composition and economic returns. These experiments showed that pre-slaughter fasting for up to 36 h prior can be used to avoid weight discounts in heavyweight pigs without negatively impacting carcass composition and maintaining overall revenue. However, these advantages come with a potential reduction in carcass weight and increased incidence of leaking ingesta, which can result in condemned heads. Experiments 11, 12, and 13 compared phase-feeding to blending diets using an automated feed delivery system. These studies showed that corn-supplement blending is not economical and feeding diets blended to a Lys curve results in lower feed costs compared to phase-feeding, but due to reductions in growth and carcass weight, these savings do not translate into higher income over feed cost. Finally, Exp. 13 showed that over- and under-budgeting situations do not significantly influence overall returns, but pigs fed under-budgeted diets performed more closely to those fed correctly estimated feed budgets.
