Download or read book In Vivo and in Vitro Studies with Growing Pigs on Standardised Ileal Amino Acid Digestibilities in Grain Legumes written by Dagmar Jezierny and published by Cuvillier Verlag. This book was released on 2009-12-09 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since there is a general ban on meat and bone meal and its by-products in diets for livestock in the EU, it is crucial to focus on alternative protein feed ingredients to be used in pig nutrition. Beside soybean meal as a commonly used plant protein supplement, grain legumes may also be used as alternative protein sources in diets for pigs. Current protein evaluation system for feed ingredients for pigs are based on the concept of standardised ileal digestibilities (SID) of crude protein (CP) and amino acids (AA), but there is a scarcity of information on SID of CP and AA in grain legumes grown in Central Europe. Therefore, the objective of the thesis was to determine the chemical composition and the SID of CP and AA in seed-grade cultivars of faba beans (Vicia faba), peas (Pisum sativum) and lupins (Lupinus spp.) in growing pigs using the difference method. Furthermore, to obtain SID of CP and AA, the basal ileal endogenous CP and AA losses in growing pigs were estimated by means of regression analysis from apparent ileal digestible and total dietary contents of CP and AA. A further aim of the thesis was directed to the validation of an in vitro procedure for estimates of SID of CP and AA in the same grain legumes by means of a two-step enzymatic method with subsequent pepsin and pancreatin incubations. The in vitro predicted SID values were compared with their corresponding in vivo SID values. The chemical composition and SID values of CP and AA measured in faba bean, pea and lupin cultivars generally were in good agreement with tabulated values. The average SID of CP and most AA in lupin cultivars (CP, 87%) were higher than in pea (CP, 79%) or faba bean cultivars (CP, 76%) Comparably low SID values in some faba bean cultivars can be partly explained by their contents of condensed tannins. In contrast to SID values in faba bean cultivars, there were only small variations in SID values between individual cultivars of peas or lupins. Results of the in vitro experiment revealed that predicted SID of CP and AA do not provide direct estimates of SID values in grain legumes, because the in vitro predicted SID values were generally higher than in vivo SID values. The use of multiple linear regression analysis with grain legume species as a covariate resulted in strong linear relationships. Further investigations are warranted to study if these principles apply to other feed ingredients as well. Moreover, the use of in vitro predicted SID values in practical diet formulations for pigs needs to be further validated.

Download or read book Potential of cereal grains and grain legumes for modulation of pigs intestinal microbiota written by Tobias Aumiller and published by Cuvillier Verlag. This book was released on 2015-09-10 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native carbohydrate fractions of major dietary components in pig nutrition, such as dietary fiber, resistant starch and oligosaccharides in whole cereal grains or grain legumes appear to be appropriate to manipulate the porcine gut microbiota. Therefore, the objective of this thesis was to evaluate effects of differences in carbohydrate composition of cereal grains, grain legumes and feed supplements on the intestinal microbiota in pigs. Based on a comprehensive literature research, an overview on the current research on the effect of whole grain cereals and grain legumes as well as their by-products on the pigs’ intestinal microbiota in relation to their carbohydrate composition was given. An in vivo experiment was carried out to determine the effects of 8 recently introduced genotypes of barley or wheat on ileal and fecal microbiota of grower pigs by means of quantitative real-time PCR. In addition, in a second experiment the effect of ultra-fine ground fibers from wheat, lupins and peas in comparison to inulin and basal substrates on the microbiota composition and formation of microbial metabolites was determined in vitro using the modified Hohenheim Gas Test. In agreement with previous studies, the potential to modulate the pigs’ intestinal microbiota with cereal grains and feed supplements based on cereal grain or grain legume fibers was shown. However, it was not possible to assign the observed effects on the bacterial groups to the dietary carbohydrates known to influence the intestinal microbiota, such as arabinoxylan or β-glucan.

This book was released on 2023-08-28 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This series of meetings bring together experts working in this field of Science from throughout the world. A major feature of each conference session is an invited review, which outlines the advances that have been made in a particular area since the last meeting. A major factor that was considered at this meeting was the likely impact of plant genetic modification on the nutritional quality of their seeds for human and animal feeding. As an example already a number of legume species and rapeseed have been modified to improve the sulphur amino acid content of their seed and thus their protein quality. Besides the major grain legume species and rapeseed that had been discussed at previous meetings in this series number of crop products, as potential protein sources, for animal feeding, were considered for the first time. These included cottonseed meal, linseed meal, and sunflower seed meal. The potential of some new exotic crops from Mexico was also covered including Mexican species of the genus Lupinus and a Mexican plant from the same family as castor bean, which has a very high oil content but is usually toxic. Work from Cuba compared the nutritional characteristics of soybean with a range of tropical grain legume species, which have received little previous attention. A major change at this meeting was the greater consideration of the effects, both positive, and negative, of the consumption of these seeds for human nutrition. A major review on the development of allergnicity to legume seed in humans is included. There was also consideration of the potential role of antinutritional factors in reducing the growth of various types of tumour cells. The presented papers also suggest that the consumption of legume seed in the diet can potentially reduce serum cholesterol levels. Overall from the 5 conference sessions there are 52 papers. Of these 7 are major invited reviews on the current state of research in this important area for human and animal feeding."
