Available in PDF, EPUB and Kindle. Book excerpt: Weaning is a stressor that can negatively impact pig performance. Similarly, maternal stress, such as bacterial infection, may alter programming of the fetal hypothalamic-pituitary-adrenal axis and the immune system, ultimately affecting offspring performance and predisposing them to disease later in life. Omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementation of nursery pigs or sows may reduce stress and promote nursery pig health and growth. Fish oil (FO) is considered a major source of n-3 PUFA; however, microalgae (AL) may provide an alternative source of n-3 PUFA. The objectives of this thesis were to investigate the effects of AL and FO supplementation in nursery pig and sow diets on nursery pig growth, stress and immune responses. In our first study, piglets were fed low-quality protein diets supplemented with AL, FO, or a corn oil (CO) control. In our second study, sows were fed diets supplemented with AL, FO, or CO in late gestation, and were immune challenged with lipopolysaccharide (LPS) on gestation day 112 to simulate a bacterial infection; their offspring were then placed on high- or low-quality protein diets at weaning. In both trials, the piglet stress response was assessed using an LPS immune challenge, and fever, cortisol and cytokine responses were measured to assess the acute-phase response. The piglet acquired immune response was also assessed using a dermal hypersensitivity challenge with novel protein antigens ovalbumin (OVA) and Candida Albicans (CAA), as well as by measuring OVA- and CAA-specific antibody responses. Results from the first trial showed that neither AL, nor FO supplementation affected offspring growth, however, both supplements reduced the fever response following LPS challenge. The AL treatment also resulted in increased cytokine concentrations. Results from the second trial showed that concentrations of cytokines were not affected by maternal diet and LPS immune challenge, but were decreased in pigs fed a low-quality protein diet. Despite the lack of maternal effects on the serum cytokine response, changes in male offspring adrenal transcriptome suggest that maternal treatments can influence lipid metabolism, steroidogenesis and immune response in the offspring. In both trials, the acquired immune response was not affected by the experimental treatments.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pork producers operate under tight profit margins. Nursery diets are the most expensive in the pork production cycle. Therefore, this thesis investigated the use of low-complexity (LC) diets in the nursery and assessed the effects of deoxynivalenol (DON) contamination and the supplementation of a commercial feed additive or fish oil on pig growth performance, gut morphology, and immune response to assess application to industry. Growth performance was not different for pigs fed LC diets with no or low DON contamination than pigs fed the high-complexity diet as the same bodyweight was reached by the end of the nursery period. The commercial feed additive improved certain immune parameters and gut morphology when feeding high DON-contaminated diets but did not rescue growth performance. Therefore, low-complexity diets could be fed to nursery pigs so long as DON-contamination is below 1.5 ppm, and the commercial feed additive may improve immune function and gut morphology.

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

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Swine Nutrition As climate change continues to have a significant impact on the modern world, it is crucial to find alternative sources of energy and nutrients for swine production. The development of optimal feeding revolves around a multitude of considerations—genetic variations in the pig, variability, availability, and stability of nutrients in feed ingredients, interactions among nutrients and non-nutritive factors, voluntary feed intake, physical (& social) environment of pigs, and more. Establishing the ideal network of factors will only grow in importance as humans assess the methods for our own food networks. Sustainable Swine Nutrition is a comprehensive book on swine nutrition, covering some fundamental aspects of nutrition—namely digestive physiology, water, protein or amino acids, lipids, carbohydrates, energy metabolism, vitamins, minerals, and nutrition and immunology. Providing the most up-to-date information on each of these areas, a major emphasis of this second edition is on recent developments and current advances in the field, with a focus on pertinent issues linked with energy and nutrients. In doing so, the book highlights topics and issues that can contribute to the ultimate goal of successful and sustainable swine production. Sustainable Swine Nutrition readers will also find: Environmentally friendly, optimal feeding strategies for successful and sustainable swine production Recent developments, such as alternative feedstuffs, feed additives, and bioavailability Expanded treatment and new chapters on swine physiology, energy and protein, technology, and more Sustainable Swine Nutrition, Second Edition, is an ideal resource for livestock scientists and industry professionals involved in all aspects of pork production.

Download or read book Effects of Commercial Feed Additives on Growth Performance and Gut Microbiota of Nursery Pigs written by Xiaoyuan Wei and published by . 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.

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.
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.
