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.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. 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 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.

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.

Pegg and published by . This book was released on 2014 with total page 107 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 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.

This book was released on 2023-08-28 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Globally, the face of pig and poultry production is changing. The global emphasis on ethanol production has diverted significant proportions of grain away from animal production, thus increasing the cost of feed. This has forced the pig and poultry industries to scrutinise their production methods investigating alternative feed ingredients together with methods of improving productivity and efficiency in order to survive. This edited collection of papers is taken from a series of seminars that brought together some of the world's leading authorities in the field of pig and poultry nutrition and production. The fundamental theme is to address the interaction between nutrition and the gut ecosystem as a means to enhance health, performance and ultimately profitability. The importance of gut development and the intestinal ecosystem as a whole, and their impact on health and disease are covered in-depth. The roles of specific feed ingredients are also discussed. 'Gut efficiency: the key ingredient in pig and poultry production' is aimed at nutritionists and animal producers as well as students and researchers studying animal and applied biological sciences."

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive collection of cutting-edge research on feed additives for a sustainable animal production, including insects and aquaculture. In five clearly structured sections, the sources of feed additives, details on their biochemistry, feed security as well as specific applications for individual farm animal species, livestock health and product characteristics (meat, milk and eggs) find attention. International expert authors provide a full description on the use of aromatic plants, extracts and essential oils as feed additives alone or in combination with functional feeds of different categories. Readers will explore the potential of feed additives to tackle environmental issues. Practical examples include the use of local feedstuffs in combination with herbal additives and enzymes. Emphasis is placed on the consequences of using local feed sources versus imported feedstuffs on global warming potential, primary energy use, nutrient excretion and the feed additive influence on lessening the pollution from animal operations. The results presented will support realization of the Sustainable Development Goals, in particular SDG 12 which stands for Responsible Consumption and Production worldwide. The use of novel and different feed additives can be an important tool to enhance sustainability, support productivity, and match increased food demands around the globe. Animal production depends on feed efficiency to sustain growth and profitability. Along these lines, the present volume is an essential reading for all future-oriented veterinarians, animal nutritionists, agricultural scientists, and moreover the feed, food and plant industry.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments evaluated the effects of feeding growth promoting alternatives, alone or in combination, on nursery pig performance in comparison to a common feed additive, carbadox. In Exp. 1, 288 weaned pigs (Line 600 × 241; DNA, 5.36 kg) were used in a 42-d study. Pigs were allotted to 1 of 9 dietary treatments in pens of 4 at weaning in a randomized complete block design with 8 replications per treatment. Dietary treatments were arranged with a negative control diet with no dietary feed additive, a positive control with added carbadox or 7 treatments including added copper sulfate (CuSO4; 0 vs. 125 ppm Cu) and added zinc oxide (ZnO; 0 vs. 3,000 ppm Zn from d 0 to 7 and 2,000 ppm Zn from d 7 to 28), essential oils from XTRACT 6930 at 0.91 kg/ton, Safman (yeast cell walls) at 0.23 kg/ton, Biosaf HR (yeast cells) at 0.68 kg/ton. These supplements were fed alone or in combination. From d 0 to 7 experimental diets were a pelleted diet and fed in a meal form from d 7 to 28, followed by a common corn-soybean meal-based diet from d 28 to 42. Essential oil blend (cinnamaldehyde) and yeast had no (P> 0.05) effect on ADG. Feeding carbadox or added trace minerals (Cu and Zn) improved ADG (P 0.05) of nursery pigs compared to the control. Carryover effects from any of these dietary treatments on subsequent growth performance were not (P 0.05) different. The use of added trace minerals Cu and Zn alone or in conjunction with either yeast or essential oil blend (cinnamaldehyde) results in ADG and G/F comparable to carbadox. In Exp. 2, 280 weaned pigs (Line 600 × 241; DNA, 5.18 kg) were used in a 35-d study. Pigs were allotted to 1 of 7 dietary treatments in pens of 5 at weaning in a randomized complete block design with 8 replications per treatment. Dietary treatments were arranged with a negative control diet with no dietary feed additive, a positive control with added carbadox or 5 treatments including added copper sulfate (CuSO4; 0 vs. 125 ppm Cu) and added zinc oxide (ZnO; 0 vs. 3,000 ppm Zn from d 0 to 7 and 2,000 ppm Zn from d 7 to 35), and Victus® LIV (145 or 435 ppm). These supplements were fed alone or in combination (Cu/Zn and 145 ppm Victus® LIV or Cu/Zn and 435 ppm Victus® LIV. Diets were fed in meal form. Feeding carbadox, 145 ppm Victus® LIV or added trace minerals (Cu and Zn) improved ADG (P 0.05) of nursery pigs compared to the control. In summary, under the conditions of these experiments, pigs fed zinc/copper, 145 ppm Victus® LIV or a combination of these had similar (P 0.05) growth performance to pigs fed carbadox.

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 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis includes three chapters addressing very practical questions facing swine nutritionists including developing a phytase release curve to quantify the release of plant-based phosphorous in swine diets, determination of the lysine requirements in finishing diets, and control strategies for diets with high levels of deoxynivalenol (DON). One experiment using a total of 360 nursery pigs was used to determine the effect of increasing phytase on nursery pig growth performance and bone ash characteristics. Two experiments using a total of 4,223 pigs were used to determine the optimal dietary standardized ileal digestible (SID) lysine (Lys) in duroc-based sired finishing pigs. Additionally, one experiment using 4,318 pigs was conducted to evaluate dietary mycotoxin control strategies on nursery pig performance and blood measures. Experiment 1 determined the available phosphorus (aP) release of GraINzyme phytase in nursery pigs. Increasing phytase from 150 to 1,500 FTU/kg in phosphorus deficient diets improved nursery pig growth performance and bone ash characteristics. Using growth performance, bone ash weight, percentage bone ash, and formulated phytase concentrations, equations were developed to predict aP release up to 1,500 FTU/kg of GraINzyme phytase for 10- to 20- kg pigs. Experiments 2 and 3 were conducted to determine the optimal dietary SID Lys in finishing pigs. Experiment 2 determined that increasing SID Lys improved growth performance and final BW. Furthermore, feed cost, feed cost/kg of gain, revenue, and income over feed cost (IOFC) increased with increasing SID Lys. In experiment 3, increasing SID Lys increased growth performance, overall market weight, and HCW. Additionally, feed cost, revenue, and IOFC increased with increasing SID Lys. Experiment 4 determined that pigs fed diets contaminated with high concentrations of DON had decreased growth performance compared to pigs fed diets contaminated with low DON concentrations. Furthermore, when feed additives such as sodium metabisulfite (SMB), Technology1, or Technology1+ were included in high DON diets, SMB supplementation led to growth performance that exceeded pigs fed the low DON diets. In summary, these experiments provide data on aP release of GraINzyme phytase, SID Lys requirements in finishing pigs, and mycotoxin control strategies in swine diets.

Available in PDF, EPUB and Kindle. Book excerpt: Development in agricultural sciences, particularly in farm animal sciences, resulted in the increased productivity to meet the demand for high quality and relatively cheap protein sources for human nutrition. In parallel, this increased productivity challenges the adequate supply of nutrients, including protein and energy, needed to cover not only high performances, but also insure animal health and welfare, reproduction and quality of products in a sustainable environment. The precise understanding of the animal biology is crucial for animal health and welfare, sustainable animal production, and health of animal product consumers. This book focuses on combining basic and applied research and its practical applications. To achieve these goals, many important topics are presented and discussed in detail. The most important issues in this book are: physiological aspects of protein and energy metabolism and nutrition; animal health and welfare metabolic related issues; effect of feeds and feed processing on energy and protein digestion and metabolism; methodological aspects of research on protein and energy metabolism; environment protection and enhancement of the quality and health-promoting features of animal products. This book constitutes a good source of knowledge for those who like to be up to date with the newest trends and findings in energy and protein metabolism in farm animals.
