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.

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 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

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

Available in PDF, EPUB and Kindle. Book excerpt: A total of four experiments utilizing 462 weaned pigs were conducted to evaluate the use of spray-dried plasma (SDP) in early nursery diets. In the first experiment, it was determined that in diets that contained 6.75% SDP, soy protein concentrate can replace dried skim milk and dried whey provided that there is adequate lactose in the diet. In the second experiment, it was determined that a lower level of lactose (15%) was needed to maximize pig performance in a diet that contained 6.75% SDP compared to a diet that contained no SDP (30 to 45% lactose needed). The third study was conducted to evaluate if it is feed intake or a metabolic mechanism by which SDP improves nursery performance. The results of this study demonstrated that if feed intake of the diet without SDP was improved to equal the feed intake level of pigs fed the diet with SDP, growth performance was similar. Thus, SDP improves postweaning performance by improving feed intake. Additionally, it was determined that the inclusion of SDP in the diet improved intestinal health as indicated by an increased villous height and villous height to crypt depth ratio. Given that the response to SDP is greater in a conventional on-site environment that does not minimize antigen exposure, the objective of the final study was to determine if pigs fed SDP would be able to respond better to an immunological challenge using lipopolysaccharide (LPS). The results of this study demonstrated that pigs fed the diet with SDP responded much more adversely to a LPS challenge, as measured by an increase in serum adrenocorticotropin-releasing hormone and cortisol. The results of these studies suggest that SDP is able to reduce the stimulation of the immune system, thus resulting in an improvement in feed intake and growth. The exact mechanism by which this occurs is still unknown and needs to be studied further.

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: 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.

Book excerpt: In conclusion, this dissertation elucidated some of the mechanisms by which creep feeding, YDM, and SDPP improve growth and health of nursery pigs. It also demonstrated that the positive effects of SDPP on growth are mediated in part by the enhancement of gut integrity, enterocyte proliferation, and modulation of gut microbiota.

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 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.

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.

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.

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.
