This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber-rich (HF) diets are typically supplemented with enzymes to improve their nutritive value and to offset their negative effects on pig growth. However, studies on enzyme effect in pigs have yielded inconsistent results on nutrient digestibility and growth. Although the inconsistencies observed could be explained by differences in substrate and experimental conditions and enzyme characteristics among studies, how enzymes influence metabolic and physiological responses in pigs is still not clear. Therefore, three experiments were conducted, using 3 dietary treatments (control, HF and HF diet supplemented with enzymes), to elucidate the effects of supplementing an HF diet with enzymes in growing pigs. Experiment one investigated HF and enzyme supplementation on energy and nutrient digestibility, digesta volatile fatty acid (VFA) concentrations, and gut microbial profile in pigs. Compared with the HF diet, enzymes improved dry matter, starch, energy and some amino acid (AA), but not nitrogen digestibility. Further, the enzymes stimulated the growth of gut bacterial groups, which have xylanolytic and cellulolytic properties in the HF-fed pigs, but enzymes did not influence digesta VFA concentration or fiber fermentation. Experiment 2 evaluated the effects of enzyme supplementation on growth performance, glucose uptake in jejunum tissue samples mounted in Ussing chambers, and intestinal nutrient transporter mRNA levels in pigs. Diet had no effect on feed intake and jejunal glucose uptake. The enzymes influenced nutrient transporter mRNA levels but did not improve pig growth rate and feed efficiency relative to the HF diet. The third experiment investigated the effect of supplementing the HF diet with enzymes on postprandial portal vein-drained viscera (PDV) nutrient fluxes and energy expenditure (measured as O2 consumption) by the PDV and whole-animal in pigs. Diet had no effect on energy expenditure. The HF diet reduced portal glucose, VFA and essential AA absorption and insulin production. Enzyme supplementation improved portal glucose and VFA absorption, but not essential AA absorption and insulin production. Overall, improvements in nutrient utilization due to enzyme supplementation did not improve the growth rate of pigs, which appears to be due to the lack of enzyme effect on essential AA and energy use by the PDV and insulin production.

Book Synopsis The Value of Fibre by : G. González-Ortiz
Download or read book The Value of Fibre written by G. González-Ortiz and published by Brill Wageningen Academic. This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary fibre has been associated with impaired nutrient utilisation and reduced animal performance. A minimum amount of dietary fibre is required to maintain normal physiological functions in the gastrointestinal tract. This book reviews the latest advances in the understanding of dietary fibre for animal nutrition. Fibre clearly has more value than was once thought. This book attempts to define not only the analytical constraints but also the advances in understanding its role in intestinal development and health in both swine and poultry. It identifies how we can exploit fibre to the advantage of the host. Stimulating the gastrointestinal microbiota (often referred to as the second brain) to digest more fibre creates a more favourable environment for intestinal health. This outcome is especially important in antibiotic free diets. The type of fibre employed, the use of exogenous enzymes and the interaction between them, the gastrointestinal microbiota and the host will be covered in detail throughout the chapters. This book discusses the practical application of this research and has been written for all animal scientists, nutritionists, feed producers and anyone interested in exploring new developments in the understanding of dietary fibre.

Book Synopsis Energy and Protein Metabolism and Nutrition by : Mario Luiz Chizzotti
Download or read book Energy and Protein Metabolism and Nutrition written by Mario Luiz Chizzotti and published by Brill Wageningen Academic. This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.

Available in PDF, EPUB and Kindle. Book excerpt: Livestock nutrition is one of the most important issue in animal production both in physiological-economic terms as well as the impact of livestock on the environment. The handbook „Rational livestock nutrition in rural areas” has been funded with support from the European Commission under Erasmus + programme – Cooperation for innovation and good practice. The book has been developed by experts in various fields of agriculture – animal nutrition and feed science, animal husbandry, agronomy and veterinary medicine. The authors of this book, originating from five different countries – Poland, Turkey, Romania, Italy and Hungary by working within the framework of the established Strategic Partnership – Vocational Education and Training have developed a comprehensive compendium aimed at transfer of knowledge, good practice and innovation in the field of agriculture with emphasis on rational nutrition of livestock. The book covers five broad issues of livestock nutrition. Chapter one – „Physiology of Nutrition”, is related to the anatomy and functions of particular organs of the farm animals’ digestive tracts, type of nutrients found in the livestock diets, as well digestion, absorption and metabolism of these compounds. An extensive characteristics of most common used in animal nutrition feeds, their processing, feed additives as well as the mechanism of their action are presented in the second chapter – „Feed and Feed Additives”. The chapter number three – „Animal Feeding Systems in Europe” in a synthetic way explains the fundamentals of commonly used feeding systems of ruminants, pigs, poultry, horses and rabbits. This chapter also provides several schemes of daily rations/concentrate mixtures formulation for various farm animal species. An extensive chapter number four is dedicated to animal welfare as well etiology, treatment and prevention of metabolic diseases in animals that livestock breeders are struggling every day. Last but not least, the fifth chapter raises issues related to livestock production in terms of environmental and legal conditions under the common agricultural policy of member countries. The possibilities of reducing the negative impact of livestock production on the environment, so called „good practices” are discussed in this chapter. The book “Rational Livestock Nutrition in Rural Areas” is intended for people involved in animal production – mainly farmers but it can also be used by agricultural and nutritional consultants, zootechnical service workers. Students of vocational agricultural schools and, to some extent, students of natural and agricultural universities may benefit this book as well.
