Download or read book Quality of meat and fat in pigs as affected by genetics and nutrition written by Caspar Wenk and published by BRILL. This book was released on 2023-08-28 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pork is the most widely produced meat in the world. To cover the demands of a fast growing population, new scientific knowledge in genetics, physiology and nutrition is generated, which contributes in a general increase of production performance. Production systems can be improved by constructing models which help to optimise use of the means of production and intensify production. In some regions where production intensity is high, concerns about environmental pollution are increasingly becoming a limiting factor. Consumers, and with them the retailer organisations, are voicing serious concerns about the production systems and especially the use of feed additives.In the context of the above, the question of the quality of pork becomes a relevant issue. A general view can only be obtained by taking all factors into consideration.The diverse aspects of pork quality were covered in the session on "Quality of Meat and Fat as Affected by Genetics and Nutrition" at the 50th annual meeting of the EAAP in Zurich. This publication presents the review presentations which give an overview from the different perspectives of meat quality and it's use in human nutrition: genetics, physiology, animal nutrition, meat consumption and human health and consumer concerns. In addition, 38 short communications provide up-to-date knowledge on the subject of quality from a European perspective.

Download or read book Nutrient and energy digestibility in weaned piglets as influenced by feeding level and origin of soy bean meal in the diet written by Miriam Goerke and published by Cuvillier Verlag. This book was released on 2014-11-12 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feed is the greatest single cost factor in pig production, and protein and energy accounts for the largest proportion of feed costs. Therefore, it is crucial that the protein and energy content of a diet is characterized in the best possible way. Over the past years, the standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) has been introduced into diet formulation for pigs in several countries. Moreover, different energy systems are available for feed evaluation including digestible energy (DE), metabolizable energy (ME) and net energy (NE). For soybean meal (SBM), the most commonly used feed ingredient in pig diets, tabulated values for SID of AA in addition to DE, ME or NE contents have been determined in grower-finisher pigs rather than weaned piglets. Due to the lack of separate feed tables for piglets, tabulated values originating from experiments with grower-finisher pigs are being used for diet formulation in piglet feeding, although post-weaning feed intake (FI) is highly variable and often lower than 3 times the maintenance energy requirement of weaned piglets. Thus, it remains open, if values obtained with grower-finisher pigs can be used for piglets as well. Furthermore, in grower-finisher pigs it has been shown that dietary inclusion of SBM sources of different origins may affect SID of CP and AA. The influence of SBM origin on SID of CP and AA in piglets has not been investigated so far. Therefore, the first objective of the present thesis was to determine SID of CP and AA in a large variety of SBM sources sourced from different countries, whereas the second and third objective was to investigate the effect of FI level on apparent ileal digestibility (AID) and SID of CP and AA, as well as on apparent total tract digestibility (ATTD) of proximate nutrients and energy in weaned piglets. For this purpose, a digestibility experiment with a total of 36 (initial BW 5.6 kg) newly weaned pigs, surgically fitted with simple T-cannulas at the distal ileum, was conducted. The piglets were housed in metabolic crates, and were fed semi-synthetic diets based on cornstarch and 1 out of 18 different SBM batches originating either from Argentina (6 batches), Brazil (6 batches) or the United States (US; 6 batches). Diets were fed on three graded levels of FI corresponding to 30, 45 and 60 g per kg average body weight (BW) of piglets, equivalent to 50, 75 or 100 g/kg BW0.75 d or 1.9, 2.6 and 3.1 times the energy requirement for maintenance. The whole experiment was split in 3 consecutive parts with 12 piglets, each. Over the whole experiment, the piglets were randomly allocated to the different combinations of FI level and SBM, but balanced in order to achieve 3 identical experimental parts. Chapter 1 of the present thesis provides a brief introduction into the objective of this thesis, including background information on SBM production, composition, and a literature review about studies concerning the impact of SBM origin and the effect of FI level on nutrient digestibility in pigs. Chapter 2 includes information on the chemical composition and proximate constituents of the 18 SBM batches originating from Argentina, Brazil, or the US. The average content of CP was greater for Brazilian SBM (P ≤ 0.05) compared to the other 2 origins. Contents of most AA were greater (P ≤ 0.05) in Brazilian compared to Argentinean SBM batches. Amino acid contents in US SBM batches ranged between those from Argentina and Brazil. Average trypsin inhibitor activity was greatest (P ≤ 0.05) in Brazilian SBM. Mycotoxins were detected in 8 out of 18 SBM batches, but all mycotoxin levels were below their critical benchmarks. The contents of individual isoflavones varied considerably among SBM origins (P ≤ 0.05). The SID of Arg, Phe, Thr, Trp, Asp, Gly, and Ser were greater (P ≤ 0.05) for US compared to Argentinean SBM batches, and intermediate values were obtained for Brazilian SBM batches. The SID values were most variable within Argentinean SBM batches and most homogenous within US SBM batches, as indicated by a great and a small coefficient of variation, respectively. However, SID of CP and AA were not related to any of the analyzed chemical constituents. It was concluded that EU imports of SBM are generally of high quality. The obtained SID values contribute substantially to the expansion of databases on SID of CP and AA in SBM from the 3 major soybean-producing countries for piglets. However, SID values obtained with piglets were considerably lower compared with tabulated values originating from grower-finisher pigs. Thus, further studies are warranted to confirm that finally separate feed tables for ingredients used in diet formulation for piglets are required to account for these differences. In Chapter 3, the effect of 3 graded levels of FI on AID and SID of CP and AA in SBM based diets was determined in piglets. The AID and SID of most AA were quadratically affected by the FI level (P ≤ 0.05). Initially, both AID and SID of most AA increased up to 1.9 % units as the FI level was increased from 30 to 45 g/kg BW. Thereafter, these AID and SID values decreased by 2.6 and 2.7 % units, respectively, as the FI level was further increased from 45 to 60 g/kg BW. It was concluded that there is a significant effect of feed intake level, albeit of small magnitude, on AID and SID of CP and AA, which possibly has to be accounted for in feed tables, due to the high variability of voluntary FI post weaning. In Chapter 4, the effect of 3 graded FI levels on AID and ATTD of proximate nutrients and energy, as well as on estimates of dietary DE, ME and NE contents was investigated. Due to the graded level of FI, and thereby the graded intake of nutrients, ileal endogenous nutrient losses and/or total tract endogenous nutrient losses could be estimated by linear regression analysis, and true digestibility values as well as urinary endogenous N losses could be calculated. The AID of DM, N and energy as well as ATTD of neutral detergent fiber, acid detergent fiber and ether extract (EE) in the assay diets was not affected (P > 0.05) by FI level. However, there was a small decrease in ATTD of DM, N, OM, ash and energy, as well as in DE, ME and NE content in the assay diets (P

Download or read book The Effects of Feed Additives Sodium Metabisulfite and Processing Conditions on Nursery Pigs Fed Diets Containing Deoxynivalenol written by Hyatt Lowell Frobose and published by . 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.

Download or read book Nutritional Strategies of Animal Feed Additives written by Abdel-Fattah Z. M. Salem and published by NOVA. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quality of feed nutrition is influenced not only by the content but also by some other aspects such as, feed presentation, hygiene, anti-nutritional factors, digestibility and palatability. Feed additives provide a mechanism by which such dietary deficiencies can be addressed and also benefits not only associated with the nutrition and thus the growth rate of the animal concerned, but also its health and welfare. Feed additives could modify animal metabolism in specific and direct ways by improving production efficiency (weight gain or milk yield); improving carcass composition in growing animals; increasing milk yield in lactating animals; and decreasing animal waste per production unit. This book discusses the impacts of feed additives on animal metabolism, health and 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 Facts about fats written by J. Doppenberg and published by BRILL. This book was released on 2023-09-04 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fats and oils are more than 'just' energy sources for animal feeds. The fatty acids as part of triglycerides or in Fatty Acid products differ in chemical composition and physical characteristics. The omega-3 and specifically the LC-PUFA omega-3 fatty acids can be considered as functional nutrients. Via the feeding of different fats and differing fat additions body composition and animal products can be modified. The main use of fats and oils in the feed industry is however increasing the energy content of the feed economically. Therefore knowledge about the digestibility of the fat for each animal category, the metabolisible energy content and the efficiency with which this energy can be used for different production goals are of paramount importance for evaluating the fat source of choice. This book has summarized the presently available knowledge from the scientific literature and concluded with a model to estimate the energy content in practice.

Download or read book Energy and protein metabolism and nutrition written by Hélène Lapierre and published by BRILL. This book was released on 2023-09-04 with total page 384 pages. 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.
