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 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to evaluate the effects of corn byproducts high-protein died distillers grain (HP-DDG), and dried distillers grain with solubles (DDGS), and branched chain amino acids (BCAA) on the growth performance and meat quality of pigs. The first study evaluated the combined effect of dietary level of DDGS and HP-DDG on the growth performance of wean-finish pigs and carcass and pork quality characteristics. This study demonstrated that DDGS can be included at up to 30% in diets (without HP-DDG) without compromising growth performance of wean-to-finish pigs. However, growth performance was increasingly compromised at higher inclusion levels of both co-products and belly firmness was negatively affected by increasing levels of both DDGS and HP-DDG. A second experiment was designed to define the minimum CP level and whether non-essential amino acids become limiting in low crude protein diets for late finishing pigs. The results of this study demonstrated that late finishing pigs can be fed diets with 9.76% crude protein level supplemented with 0.32 % L-Lys HCL and other essential amino acids without affecting growth rate and that non-essential amino acids were not limiting in the low crude protein diets evaluated. A third study was designed to recreate the negative effects on growth performance of feeding diets with 30% HP-DDG inclusion level and to test if the negative effect of feeding high HP-DDG levels on growth performance can be reproduced by adding excess branched chain amino acids (leucine, isoleucine, and valine) to standard corn-soybean meal based diet. The results show that the reduction in the growth rates of growing pigs fed diets with 30% HP-DDG inclusion levels may be due to the dietary excesses of leucine present in diets with HP-DDG at 30% inclusion levels. The same effect was not present in finishing pigs. In general, growth performance and belly quality are compromised at higher inclusion levels of both HP-DDG and DDGS. The results of the last studies indicate that leucine level may play an important role on the reduction of the growth performance of pigs fed 30% HP-DDG inclusion levels.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 6,858 pigs were used in 6 experiments to evaluate the effects of crude glycerol, dried distillers grains with solubles (DDGS), Ractopamine HCl (RAC), NutriDense corn, and feeder adjustment on growing and finishing pig performance. In Exp. 1, pigs were fed diets with 0, 2.5, or 5% crude glycerol with 0 or 20% DDGS. Adding DDGS increased ADFI and decreased G:F with no differences for pigs fed glycerol. Neither glycerol nor DDGS affected any carcass characteristics. Pigs fed DDGS had increased iodine value in carcass fat. In Exp. 2, pigs were fed diets with 0 or 5% glycerol with 0 or 7.5 ppm RAC. Feeding RAC increased ADG and G:F and decreased ADFI while glycerol tended to improve G:F. Ractopamine HCl improved carcass traits. Loin chop drip loss worsened when glycerol and RAC were added separately, however, drip loss decreased when the combination of both were fed. Glycerol did not affect loin characteristics. Neither RAC nor glycerol influenced iodine value of carcass fat. Exp. 3 and 4 were conducted to determine the 4th limiting amino acid in diets containing NutriDense corn. In Exp. 3, pigs fed the positive control and the diet with added Ile, Trp, and Val (in combination) had greater ADG. Pigs fed added Ile or Trp had greater ADG than pigs fed the negative control indicates these amino acids were co-4th limiting for 37 to 59 kg pigs. In Exp. 4, pigs fed the positive control, added Trp, or the combination of added Ile, Trp and Val had greater ADG then pigs fed the negative control or pigs fed either Ile or Val indicates these amino acids were co-4th limiting for 77 to 100 kg pigs. Exp. 5 and 6 evaluated feeder adjustment on growth performance of finishing pigs. In Exp. 5, reducing feeder opening decreased ADFI. In Exp. 6, pigs were fed at three feeder opening and either a corn-soybean meal or byproduct-based diet. Diet type did not affect pig performance. Widening feeder openings increased ADG and ADFI. Feeder setting tended to influence G:F with the best G:F at the intermediate opening.
Download or read book Effects of Floor Space and Removal of Corn Distillers Dried Grains with Solubles on Heavy Weight Pig Performance written by Anne Bonner Lerner and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is comprised of 5 chapters consisting of a study evaluating space allowance and marketing strategies for pigs raised to 160 kg, three experiments evaluating the impact of removing corn distillers dried grains with solubles (DDGS) from finishing pig diets, four studies evaluating the use of medium chain fatty acids (MCFA) as a mitigation strategy for porcine epidemic diarrhea virus (PEDV), and development of a swine-specific undergraduate research program. In Chapter 1, four treatments were evaluated with decreasing space allowance from 1.17 to 0.71 m2/pig with only one final marketing event, plus two treatments with restricted space allowance and four or three marketing events. Increasing space allowance via increased initial pen inventory increased average daily gain (ADG), decreased average daily feed intake (ADFI), and reduced feed efficiency (G:F). Marketing pigs 3 or 4 times improved G:F compared with to the similar treatment with only one marketing event but resulted in similar weight marketed per pen. In chapter 2, pigs were switched from diets containing corn DDGS to corn- and soybean-meal based diets (CSBM) starting at 76 d prior to market. As time consuming CSBM increased, ADG and final BW increased and G:F improved. Average daily feed intake decreased with increasing time after dietary switch to CSBM. Hot carcass weight increased and iodine value decreased with increasing time after DDGS removal from diets. Chapter 3 also evaluated the removal of corn DDGS from finishing pig diets but utilized two seasonal marketing strategies. Regardless of marketing strategy, switching pigs from DDGS to CSBM resulted in increased carcass yield and decreased iodine value, yet live growth performance was marginally impacted. In chapter 4, four experiments were conducted to evaluate the efficacy of applying MCFA to swine feed on detection and infectivity of PEDV. Applying chemical mitigants both prior to and post-PEDV inoculation was effective at reducing PEDV detection via quantitative real time reverse transcriptase polymerase chain reaction (qRT-PCR). When tested individually and in combination and applied before viral inoculation, caproic and caprylic acid appeared to provide the greatest reduction of detectable genetic material. The addition of a 1:1:1 blend of C6:C8:C10 at 0.5% and 0.3% C8 prevented infection in in vivo bioassay. Lastly, chapter 5 presents a model to develop a species-specific undergraduate research program in the context of a swine nutrition program that is currently in use at Kansas State University. This program utilizes both graduate students and faculty to provide mentorship and has several project types that vary in level of student involvement. The program is designed to provide a comprehensive research experience, with an emphasis on including the student in pre- and post-trial activities beyond data collection. A majority of students that complete the undergraduate research program enter graduate or veterinary degree programs upon completion of their undergraduate work and cite undergraduate research as a critical step in their career selection process and professional development.
Download or read book Effects of Dietary Enzymes Or Specialty Proteins on Nursery Pig Performance written by and published by . This book was released on 2009 with total page pages. 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
Download or read book Effects of Pelleting and Dietary Fat and Fiber Levels on Pig Growth and Fat Quality written by Jeremiah Eugene Nemechek and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 11 experiments, 7,325 pigs were used to determine the effects of: 1) diet type and form on finishing pig growth performance and carcass fat iodine value (IV); 2) pellet quality and feeder adjustment on pig growth performance; 3) corn particle size and diet form on finishing pig growth performance and carcass characteristics; and 4) dietary acidification, diet complexity, and feed-grade antibiotics on nursery pig growth performance. Feeding diets with wheat middlings and dried distillers grains with solubles all the way until marketing decreased G:F and carcass yield, and worsened carcass fat IV. Withdrawing these ingredients 17 d prior to market restored carcass yield, but resulted in small improvements in IV. Pelleting diets improved growth performance; however, a novel finding is that pelleting diets fed to finishing pigs increased belly fat IV. Feeding nursery pigs from a wide feeder gap may improve ADG and ADFI, with no negative effects on G:F. For finishing pigs, reducing feeder gap reduced feed disappearance and improved G:F. In all experiments, feeding pelleted diets improved G:F, but the greatest improvements occurred when the percentage of fines was minimized. Grinding corn finer than 650 microns decreased ADFI and improved G:F for finishing pigs fed meal diets, but not for pigs fed pelleted diets. Pelleting diets improved ADG and G:F, but the greatest magnitude of G:F improvement to pellets occurred when pigs were fed diets containing the largest particle size corn. Thus, grinding corn finer than 650 microns improved feed efficiency for finishing pigs fed meal diets, but provided no additional benefit for pigs fed pelleted diets. When dietary supplementation of benzoic acid was evaluated, added benzoic acid in nursery pig diets did not influence growth performance in university conditions, whereas feeding complex diets or antimicrobials improved growth. In the commercial setting, acidifiers improved growth in one experiment but not the other. The varying response to acidifiers is likely influenced by health status, age, or starting weight of pigs.

Book excerpt: Aflatoxins are a group of highly toxic and carcinogenic substances, which occur naturally, and can be found in food substances. Aflatoxins are secondary metabolites of certain strains of the fungi Aspergillus flavus and A. parasiticus and the less common A. nomius. Aflatoxins B1, B2, G1, and G2 are the most important members, which can be categorized into two groups according to the chemical structure. As a result of the adverse health effects of mycotoxins, their levels have been strictly regulated especially in food and feed samples. Therefore, their accurate identification and determination remain a Herculean task due to their presence in complex food matrices. The great public concern and the strict legislation incited the development of reliable, specific, selective, and sensitive analytical methods for pesticide monitoring that are discussed in this book.
