Book Synopsis Nutrient and energy digestibility in weaned piglets as influenced by feeding level and origin of soy-bean meal in the diet by : Miriam Goerke
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 Weaning the pig written by J.R. Pluske and published by BRILL. This book was released on 2023-08-28 with total page 432 pages. Available in PDF, EPUB and Kindle. 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.

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.
