Download or read book Evaluating the Effects of Specialty Protein Sources on Nursery Pig Performance written by Aaron Michael Jones and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 6,465 nursery pigs were used in 8 experiments. Experiment 1 investigated the effects of Lactobacillus plantarum (LP) or fermented soybean meal (FSBM) on nursery pig growth performance. A LP x FSBM interaction was detected for G:F, where LP and FSBM individually improved G:F, but the effect was not additive. Experiment 2 evaluated the effects of increasing levels of LP on nursery pig performance. No evidence for differences in growth performance were observed among dietary treatments. Experiment 3 and 4 examined the effects of fish meal source and level on nursery pig growth performance. Overall, a source x level interaction for ADG, G:F and final BW was observed as increasing fish meal source 1 improved ADG and G:F; however, pigs fed fish meal source 2 had improved ADG and G:F at 3%, but decreased at 6%. Pigs fed fish meal source 3 had no further improvements in ADG and G:F beyond the 3% inclusion. No evidence for differences were detected between the dietary treatments for ADFI. Experiment 5 evaluated the effects of feeding fish solubles on nursery pig performance. Pigs fed diets with fish meal had increased ADG and ADFI compared to pigs fed the control diet. There was no evidence for differences in growth performance as fish solubles increased. Experiment 6 and 7 investigated the effects of enzymatically-treated soybean meal (ESBM) on nursery pig performance. Results indicated that nursery pigs fed diets with greater than 9% of ESBM resulted in decreased ADFI and final BW. Experiment 8 evaluated the effects of dietary electrolyte balance (dEB) on nursery pig performance. Increasing dEB in diets from weaning to 21-d after weaning resulted in an increase in ADG and BW, which was the result of a marginally significant improvement in ADFI and G:F. Finally, an experiment was conducted to determine the optimal strategy for collecting and submitting samples that adequately describe the nutrient levels in diets collected from a commercial swine facility. Sampling feeders with a probe resulted in less variability on an individual basis, but seemed to get washed out when individual samples were pooled to form a composite sample.

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.

Book Synopsis Investigating the Effects of Calcium Carbonate and Benzoic Acid, Corn Protein Sources, and a Dried Fermentation Product in the Diets of Nursery Pigs by : Alan J. Warner
Download or read book Investigating the Effects of Calcium Carbonate and Benzoic Acid, Corn Protein Sources, and a Dried Fermentation Product in the Diets of Nursery Pigs written by Alan J. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Eight experiments used 1,712 pigs to determine influences of dietary enzymes or specialty proteins on nursery pig performance. Experiments 1 and 2 evaluated the effects of fish meal, fermented soybean meal, or dried porcine solubles on performance. Experiment 1 showed pigs fed dried porcine solubles had improved (P = 0.01) ADG and G:F compared to pigs fed the control diet, and improved (P = 0.03) G:F compared to pigs fed the combination of fermented soybean meal and fish meal. Experiment 2 showed pigs fed increasing fermented soybean meal had improved (quadratic, P = 0.03) G:F. Experiments 3 and 4 evaluated the effects of commercial enzyme addition to diets containing dried distillers grains with solubles (DDGS) on performance. In experiment 3, neither DDGS nor enzyme addition influenced (P> 0.10) ADG and G:F. Experiment 4 found there were no (P> 0.32) enzyme x DDGS source interactions. Corn DDGS did not influence pig performance (P> 0.36). Sorghum DDGS reduced (P = 0.003) G:F, with no difference between sorghum DDGS sources. Adding enzymes to 30% DDGS diets did not improve (P> 0.57) performance. Experiments 5 and 6 evaluated the effects of fish meal (SMFM), spray-dried animal plasma (SDAP), or peptone on performance. In Experiment 5, different specialty proteins had similar (P> 0.10) ADG, ADFI, or G:F. Experiment 6 showed pigs fed 4% Peptone 2 during phase 1 and 2% Peptone 2 during phase 2 had improved (P
Book Synopsis Evaluation of Compensatory Gain, Standardized Ileal Digestible Lysine Requirement, and Replacing Specialty Protein Sources with Crystalline Amino Acids on Growth Performance of Nursery Pigs by : Jeremiah Eugene Nemechek
Download or read book Evaluation of Compensatory Gain, Standardized Ileal Digestible Lysine Requirement, and Replacing Specialty Protein Sources with Crystalline Amino Acids on Growth Performance of Nursery Pigs written by Jeremiah Eugene Nemechek and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 5,212 nursery pigs were used in 11 experiments to evaluate amino acids in nursery pig diets. Experiments 1 and 2 were conducted to determine whether the Lys level fed during one phase of the nursery influenced the response to Lys during subsequent phases. Experiment 1 tested a wide range of dietary Lys in 2 phases and reported that pigs fed high Lys during each period had increased growth performance; however, compensatory growth occurred for the pigs previously fed low Lys diets, resulting in no impact on overall ADG or final BW. Experiment 2 tested a narrow range of dietary Lys in 3 phases and found that marginally deficient diets can be fed in the early nursery phases without influencing final BW or the response to Lys levels in subsequent phases. Both experiments demonstrate that the low dietary Lys levels used in each can be fed in the early nursery phases with no negative impact on overall nursery growth rate provided that adequate levels are fed thereafter. Experiments 3 to 6 were conducted to determine the standardized ileal digestible (SID) Lys requirement of nursery pigs from 7- to 14-kg. Data from all experiments were combined and break-point and quadratic broken-line analysis was used to determine the estimated SID Lys requirement. The SID Lys requirement for optimal growth was at least 1.30% for ADG and 1.37% for G:F, or at least 3.86 and 4.19 g SID Lys/Mcal ME, respectively. Experiments 7 to 11 were conducted to evaluate the effect of replacing specialty protein sources with crystalline AA and AA requirements for 7- to 12-kg pigs. Experiment 7 demonstrated that crystalline AA can be used to replace fish meal in diets with no negative effects on growth performance. Experiment 8 demonstrated that L-Trp, L-Val, and a source of non-essential AA were needed in low-CP, AA-fortified nursery diets to achieve maximum growth performance, whereas the addition of L-Ile was not required. Experiment 9 indicated that feeding greater than 7.35% total Lys:CP decreased growth performance and Exp. 10 indicated that a SID Val:Lys ratio of 65% was sufficient for optimal growth of early nursery pigs. Implementing the results from the previous experiments, Exp. 11 determined that crystalline AA in nursery pigs diets can replace high amounts of fish meal, meat and bone meal, and poultry meal when balanced for minimum AA ratios and maximum Lys:CP with no negative effect on growth performance.
Book Synopsis Effects of Reduced Protein and Diet Complexity on Performance and Cost of Nursery Pigs by : Guilherme Hosotani

This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two 35-d experiments were conducted to investigate the effect of reducing crude protein by 2.5% and diet complexity with amino acid supplementation on performance and feed cost during the nursery phase. In Exp. 1 and 2, 32 PIC barrows (initial wt. = 7.28 ± 0.44 and 6.89 ± 0.77 kg, respectively) were weaned at 21 d and allotted to one of four dietary treatments in a completely randomized design (RCD) with four replicate pens per treatment with two pigs/pen. The four diets were: 1) corn-soybean meal based diet; 2) diet 1 with inclusion of fishmeal (FM) and spray-dried plasma (SDP) in Exp. 1 or soy protein concentrate (SPC) and spray-dried blood cells (SDBC) in Exp. 2; 3) low crude-protein diet (LCP) with 2.5% reduction; 4) LCP containing FM and SDP in Exp. 1 or SPC and SDBC in Exp. 2. In order to reduce CP by 2.5%, diets were supplemented with synthetic lysine, methionine, threonine and tryptophan (Trp) in Exp. 1 and in Exp. 2, LCP diets were additionally fortified with synthetic valine (Val) and isoleucine (Ile). Blood samples were collected on d 14, 21, 28 and 35 for determining plasma urea N (PUN). Growth performance was determined weekly. Overall in Exp. 1, pigs fed corn-soybean meal based diet containing higher CP had greater ADG (P = 0.001) than pigs fed LCP diet (0.60 vs. 0.52 kg/d, respectively) and final BW (25.28 vs. 22.95 kg, respectively) (P = 0.002). Pigs fed diets containing FM and SDP had higher final BW when compared to pigs fed less complex diets (24.87 vs. 23.35 kg, respectively) (P = 0.034). These data suggest that Val and Ile become the next limiting amino acids in LCP nursery diets. In Exp. 2, there was no effect on overall ADG and final BW. However, pigs fed HCP diets had decreased ADFI (P = 0.009) when compared to pigs fed LCP diets (0.92 vs. 1.01 kg/d, respectively). Meanwhile, pigs fed diets containing SDBC and SPC had decreased ADFI (P = 0.019) compared to pigs fed noncomplex diets (0.93 vs. 1.00 kg/d, respectively). Overall in Exp. 1 and 2, pigs fed LCP diets had lower PUN concentration (P

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. 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.
Book Synopsis Effects of In-feed Additives on Performance, Gut Microbe Ecology, and Antimicrobial Susceptibility of Enterobacteria on Nursery Pigs by : Hayden Ervin Williams
Download or read book Effects of In-feed Additives on Performance, Gut Microbe Ecology, and Antimicrobial Susceptibility of Enterobacteria on Nursery Pigs written by Hayden Ervin Williams and published by . 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.

Download or read book Effects of Amino Acid Inclusion, Oil Source Or Mineral Supplementation of Swine Diets on Finishing Or Nursery Pig Performance written by Kyle Edward Jordan and published by . 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
Book Synopsis The Effects of Nursery Pig Diet Complexity on Growth Performance and Carcass Quality in Various Commercial Swine Settings by : Heather Reinhardt
Download or read book The Effects of Nursery Pig Diet Complexity on Growth Performance and Carcass Quality in Various Commercial Swine Settings written by Heather Reinhardt and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Early nursery pig diets contain costly, highly digestible protein ingredients that improve growth and the transition at weaning. A large-scale study was conducted on multiple commercial swine farms in Southern Ontario to assess the influence of nursery diet complexity on growth performance from weaning to a targeted market weight, carcass traits at time of processing and a serum health biomarker (i.e. haptoglobin). Two dietary treatments were applied during the nursery period, one treatment was high complexity (HC) nursery diets and the second treatment was low complexity (LC) nursery diets. Overall, feeding LC nursery diets did not influence pig growth performance, or serum haptoglobin concentrations. Carcass quality traits and carcass value was also not influenced by nursery diet complexity. Reducing nursery diet complexity may be a feasible alternative to help reduce the cost of pork production.
Book Synopsis Dietary Calcium and Phosphorous Requirements and Feed Management for Nursery Pigs by : Fangzhou Wu
Download or read book Dietary Calcium and Phosphorous Requirements and Feed Management for Nursery Pigs written by Fangzhou Wu and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The dissertation consisted of 6 chapters involving studies in heavy weight market pig production, dietary Ca and P requirements for nursery pigs, antimicrobial resistance development in finishing pig microbiota, seasonal growth variability in commercial pig production, and leftover feed management in wean-to-finish pig productions. The first chapter presents a thorough review of published studies involving genetic selection, nutritional requirements, health, welfare, and pork quality of finishing pigs with marketing weight greater than 130 kg and assessed future research needs. Chapter 2 describes 2 experiments that evaluated the growth performance and percentage bone ash of early nursery pigs fed various combinations of Ca and P provided by inorganic sources or phytase. Feeding more than 0.90% dietary Ca decreased average daily gain (ADG), average daily feed intake (ADFI), gain:feed ratio (G:F), and percentage bone ash when diets were at or below NRC (2012) requirement for standardized total tract digestible (STTD) P. However, adding inorganic P or phytase to P deficient diets improved pig performance and alleviated the negative impacts of high dietary Ca concentration on growth performance. The experiment presented in chapter 3 characterized the dose-response to increasing digestible P in diets without or with 2,000 units of phytase for 6- to 13-kg pigs. Increasing STTD P from 80 to 140% of NRC (2012) requirement estimates in diets without phytase, and from 100 to 170% of NRC (2012) in diets with phytase, improved ADG, G:F, and percentage of bone ash. Estimated STTD P requirements varied depending on the response criteria and statistical models and ranged from 91 to >140% of NRC (2012) in diets without phytase, and from 116 to >170% of NRC (2012) for diets containing phytase. In addition, phytase exerted an extra-phosphoric effect on promoting pig growth and improved the P dose responses for ADG and G:F. In chapter 4, a study was conducted to determine the effects of tylosin administration route (through feed, drinking water, or intramuscular injection) on the growth performance and the development of antimicrobial resistance in fecal enterococci of finishing pigs. Pigs that received tylosin injection had decreased ADG and G:F compared with control pigs that did not receive any antibiotic treatment, which may be due to a stress response to the handling during injection administration. Moreover, tylosin administration via injection and feed resulted in a higher probability of enterococcal resistance to erythromycin and tylosin compared with drinking water treatment. Chapter 5 presents a retrospective analysis on the seasonal growth patterns of nursery and finishing pigs in 3 commercial production systems located in the Midwest US. Nursery ADG and ADFI expressed prominent seasonal variations and were similar among systems, whereas nursery G:F was not affected by season. Finisher ADG, ADFI, and G:F varied over seasons, but the magnitudes and patterns of change were system dependent. This chapter also presents the concepts underlying the implementation of a multi-level linear mixed model of production records to analyze seasonality and potentially other decision factors in commercial systems. Finally, in chapter 6, 2 experiments were conducted regarding the strategy of managing leftover finisher feed in a wean-to-finish production system. Experiment 1 evaluated the timing (phase) of feeding 2.5 kg/pig of finisher feed in a 5-phase nursery program. All growth responses decreased immediately when the finisher feed was blended into nursery diets; however, pigs greater than 11 kg (phase 3) had improved ability to compensate for the negative effects of finisher feed on overall growth performance. Experiment 2 was then carried out to investigate the maximum amount of finisher feed can be fed to 11-kg pigs. Increasing the finisher feed budget from 0 to 3.75 kg/pig resulted in a linear decrease in ADG and ADFI. However, the economic analysis indicated no change in income-over-feed-cost due to the timing and dose of blending finisher feed into nursery diets.
Book Synopsis The Effects of Fumonisin and High Protein Dried Distillers Grain on Pig Growth Performance by : Zhong-Xing Rao
Download or read book The Effects of Fumonisin and High Protein Dried Distillers Grain on Pig Growth Performance written by Zhong-Xing Rao and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiment 1 used a total of 350 pigs to determine the effects of increasing fumonisin concentration from 7.2 to 35.1 mg/kg on nursery pig growth performance and serum sphinganine (SA) to sphingosine (SO) ratio. Experiments 2 and 3 used a total of 650 pigs to determine the efficacy of various commercial products on growth performance and serum SA:SO ratios of nursery pigs fed high fumonisin diets. Experiment 4 used a total of 1,890 pigs to determine the effects of pigs fed diets with high-protein dried distillers grains (HPDDG) or conventional dried distillers grains with solubles (DDGS) on growth performance and carcass characteristics. Experiment 1 determined that increasing fumonisin concentration linearly reduced growth performance and final BW, and linearly increased serum SA:SO ratios. These results demonstrate that for 20- to 60-lb nursery pigs, diets containing greater than 32.7 mg/kg of fumonisin should be avoided, as increasing fumonisin concentration worsens growth performance and serum SA:SO ratio. In Exp. 2 and 3, growth performance and serum SA:SO ratios were improved in pigs fed high fumonisin diet with Biofix Select Pro, but not with Kallsil Dry or Feed Aid Wide Spectrum. The improvement in serum SA:SO ratios with Biofix Select Pro was only found in pigs fed 30 mg/kg of fumonisin (Exp. 3), but not 60 mg/kg (Exp. 2). In Exp. 4, there were no differences observed in ADG between pigs fed either DDG sources. Increasing either conventional DDGS or HPDDG decreased carcass yield and HCW; however, there were no differences between pigs fed HPDDG or conventional DDGS. Iodine value (IV) increased with increasing either DDG sources, and was greater in pigs fed HPDDG than conventional DDGS, which was probably due to the difference in oil content.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nursery pigs are defined as newly weaned pigs adjusting to a solid-plant based diet after being weaned from a milk-based diet. Weaning has nutritional, environmental, social, and physiological impacts on the nursery pig. Nutrition is modified to accommodate changing needs of the nursery pig. The nursery pig diet is developed by adding highly digestible animal proteins to the standard corn-soybean meal swine diet. Development of the nursery diet improves pig performance but animal-based proteins can be expensive and do not address undigestible components of the plant-based ingredients. Addition of lower-cost animal proteins, addition of enzymes, and addition of acidifiers have the capability to improve nutrient utilization of corn-soybean meal diets by nursery pigs at a lower cost. This thesis consists of four chapters. Chapter one consists of a literature review examining nursery pig management and nutrition in the United States swine industry. Chapter two examines the effectiveness of independent addition of spray-dried blood plasma or spray-dried egg to improve nursery pig growth performance when added to the standard nursery diet. Chapter three examines the effectiveness of the independent and joint addition of alpha-galactosidase and citric acid to improve nursery pig growth performance when added to a corn-soybean meal diet. Chapter four summarizes the findings of Chapter two and three and the implications of these findings for the swine industry.
