This book was released on 1998 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic relationships between Brazilian and U.S.A. Holstein cattle populations were studies using firstlactation 305-d ME milk and fat records of 29,413 daughters of 705 sires in Brazil and 726,932 daughters of 701 sires in the U.S.A. There were 358 sires with daughter records in both countries. Data sets consisted of all herds and low and high herds stratified by within-year standar deviation for milk (HYSD) computed within counthin country. Components of (co) variance, heritability, and genetic correlations for milk and fat yields were estimated using three data groupings: all, low and high HYDS data sets form within-country and between-country bivariete and multivariate analyses, simutaneous milk and fat yields in both countries. A sire model was solved with a restricted Maximum Likelihood (REML) derivative-free algorithm. Heritabilies for milk and fat yields using all the data were smaller in Brazil (.26 and .23) than in the in the U.S.A. (.33 and .36). Genetic correlations between milk and fat were .79 in Brazil and .62 in the U.S.A. Sire and residual variances for milk yield in Brazil were 59% and 81% (all herds), 51% and 58% (low HYSD herds), and 59% and 101% (high HYSD herds) as large as those obtained for all the U.S.A. data. corresponding percentage values for fat yield were 39% and 65%, and 48%, and 41 and 80%, respectively. Genetic correlations obtained from biavariate analyses between countries ranged from .79 to .87 for milk yield and were .89 or .90 for fat yield. Parameter estimates using all data for bibariate and multivariate analyses were essentially the same. Correlated response from sire selection using the U.S.A. information increased with average HYSD Brazil: daughter response was greatest (.77 kg/kg for milk yield and .63 kg/kg for fat yield) based on information from U.S.A. half-sisters in low HYSD herds. Unequal daughter responses from unequal genetic (co) variances under restrictive Brazilian conditions support the presence of an interaction between genetype and environment, which affects the yield expectation of daughters of U.S.A. sires performing in Brazilian herd enrironments.
Book Synopsis Advanced Dairy Chemistry Volume 2: Lipids by : Patrick F. Fox
Download or read book Advanced Dairy Chemistry Volume 2: Lipids written by Patrick F. Fox and published by Springer Science & Business Media. This book was released on 2007-04-25 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Advanced Dairy Chemistry series was first published in four volumes in the 1980s (under the title Developments in Dairy Chemistry) and revised in three volumes in the 1990s. The series is the leading reference on dairy chemistry, providing in-depth coverage of milk proteins, lipids, lactose, water and minor constituents. Advanced Dairy Chemistry Volume 2: Lipids, Third Edition, is unique in the literature on milk lipids, a broad field that encompasses a diverse range of topics, including synthesis of fatty acids and acylglycerols, compounds associated with the milk fat fraction, analytical aspects, behavior of lipids during processing and their effect on product characteristics, product defects arising from lipolysis and oxidation of lipids, as well as nutritional significance of milk lipids. Most topics included in the second edition are retained in the current edition, which has been updated and considerably expanded. New chapters cover the following subjects: Biosynthesis and nutritional significance of conjugated linoleic acid, which has assumed major significance during the past decade; Formation and biological significance of oxysterols; The milk fat globule membrane as a source of nutritionally and technologically significant products; Physical, chemical and enzymatic modification of milk fat; Significance of fat in dairy products: creams, cheese, ice cream, milk powders and infant formulae; Analytical methods: chromatographic, spectroscopic, ultrasound and physical methods. This authoritative work summarizes current knowledge on milk lipids and suggests areas for further work. It will be very valuable to dairy scientists, chemists and others working in dairy research or in the dairy industry.
Book Synopsis Genetic Data Analysis for Plant and Animal Breeding by : Fikret Isik
Download or read book Genetic Data Analysis for Plant and Animal Breeding written by Fikret Isik and published by Springer. This book was released on 2017-09-09 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book fills the gap between textbooks of quantitative genetic theory, and software manuals that provide details on analytical methods but little context or perspective on which methods may be most appropriate for a particular application. Accordingly this book is composed of two sections. The first section (Chapters 1 to 8) covers topics of classical phenotypic data analysis for prediction of breeding values in animal and plant breeding programs. In the second section (Chapters 9 to 13) we provide the concept and overall review of available tools for using DNA markers for predictions of genetic merits in breeding populations. With advances in DNA sequencing technologies, genomic data, especially single nucleotide polymorphism (SNP) markers, have become available for animal and plant breeding programs in recent years. Analysis of DNA markers for prediction of genetic merit is a relatively new and active research area. The algorithms and software to implement these algorithms are changing rapidly. This section represents state-of-the-art knowledge on the tools and technologies available for genetic analysis of plants and animals. However, readers should be aware that the methods or statistical packages covered here may not be available or they might be out of date in a few years. Ultimately the book is intended for professional breeders interested in utilizing these tools and approaches in their breeding programs. Lastly, we anticipate the usage of this volume for advanced level graduate courses in agricultural and breeding courses.

Book Synopsis Animal Genomics by : Bhanu P. Chowdhary
Download or read book Animal Genomics written by Bhanu P. Chowdhary and published by S. Karger AG (Switzerland). This book was released on 2003 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides an update on the current status of gene maps in different livestock and pet/companion animal species. The findings summarized in species specific commentaries and original articles testify the rapid advances made in the field of animal genomics. Of significant interest is the fact that current investigations are providing headways for two important and exciting research fronts: targeted high-resolution mapping leading to the application of genomic information in addressing questions of economic and biological significance in animals, and the initiation of whole genome sequencing projects for some of the animal species. Like in humans and mice, this will set the stage for a new level of research and real time complex analysis of the genomes of these species. Animal Genomics signifies the beginning of a new era in this field and celebrates the achievements of the past 20 years of genomics research. It will be of special interest to researchers involved in genome analysis - both gross chromosomal as well as molecular - in various animal species, and to comparative and evolutionary geneticists.

Book Synopsis New trends for innovation in the Mediterranean animal production by : R. Bouche
Download or read book New trends for innovation in the Mediterranean animal production written by R. Bouche and published by Springer Science & Business Media. This book was released on 2012-03-26 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mediterranean area shows a great diversity of livestock systems, depending on local resources and traditions, but also on the networking space where informational resources are available for producers. During the last decades, a lot of innovations have been conceived or introduced in the Mediterranean area, allowing livestock systems to remain competitive. The book looks at two main issues: firstly, it gives an updated review on the main innovations that significantly changed the activities of livestock production in the Mediterranean area in the recent past. Secondly, the focus lies on the extent to which these innovations improve the efficiency, ensure the socio-cultural basis or reduce the environmental impact of livestock systems. One major finding is a new vision of innovating systems based on the distinction between regulated innovation (when aims are fixed) and innovative design (when aims are questioned). Innovations reported in the book are dealing with a set of concerns. They concern the production techniques, the work organization, the equipment and infrastructures, the collective features for selection, reproduction, feeding or sanitary devices. They also concern the local organization such as product labelling, new dynamics around local breeds, collective rules for supply basin or approaches of new products for new markets. More recently, some innovations focus on environmental impacts of livestock production, due to an increasing consciousness of those kinds of problems. In the final part of the book, a round table copes with a crucial question: are traditions in Mediterranean livestock activities to be considered an obstacle or a source of innovation? This book provides a set of updated information and knowledge useful for researchers, students, extension services and policy-makers in the field of animal science.
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.
