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.

Book excerpt: 'Weaning the Pig: Concepts and Consequences' is a new book that addresses the major issues surrounding the weaning process, both for piglets and the breeding herd, in modern-day pig production. The post-weaned pig presents many challenges to the manager, stockperson and nutritionist, and as such is a critical phase in the overall production system. Numerous challenges are also faced by the sow, which is required to be rebred as soon as possible after weaning. This book draws together summaries of research dealing with both piglets and the sow, and is a unique book in this regard. Accordingly, the material presented covers in detail the following areas associated with the weaning process: growth of the weaned pig, nutritional management in preparation for weaning, behavioural changes and adaptations around weaning, voluntary feed intake, digestive physiology, modulation of small intestinal integrity, the intestinal microflora and diarrhoeal diseases after weaning, intestinal immunity, nutritional requirements and intestinal requirements of the weaned pig, environmental and housing issues after weaning, saving and rearing supernumery and underprivileged piglets, and productivity and longevity of the weaned sow. The chapters have been written by acknowledged experts from around the world. The book is an ideal reference for all professions associated with the pig industry, and is invaluable as a text for students at both undergraduate and postgraduate levels.
Download or read book Effects of Fish Meal on Maternal Ovine Immune Response written by Judith A. Stryker and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of feeding fish meal to livestock have not been investigated sufficiently. To gain a broader understanding of fish meal omega fetty acid immunomodulation, different aspects of immune function were investigated. A systemic LPS endotoxin challenge, was carried out to model a systemic Gram-negative bacterial infection, and the innate immune and HPA (stress)-axis responses were assessed during late pregnancy. An antigen, HEWL, and hapten, DNCB, sensitization and challenge study was also performed to assess the innate acute phase protein response (haptoglobin) and acquired immune response (antibody and dermal hypersensitivity response) during lactation. Finally, an intramammary challenge was performed during lactation using LTA to model localized Gram-positive bacterial intramammary infection. The objectives of this study were to assess and compare local and systemic aspects of the innate and acquired immune response in pregnant and lactating ewes fed either a rumen protected fish meal (omega-3) or rumen protected soybean meal (omega-6) supplemented diet.

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 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.
