Download or read book The Comparison of Two Methods of Evaluating Inheritance of Milk Production of Dairy Sires written by Supote Srinives and published by . This book was released on 1966 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production records used were all converted to a comparable based, 305 day lactation period, two times a day milking, and mature equivalent (305 days-2-x-ME) of 71 cows from four Holstein bulls and 59 cows from four Jersey bulls were used for the study. The Equal Parent Index, Regression Index and Herd-Mate Average were calculated for each of eight bulls using five daughters and using all daughters. The study consisted of data collected from 1957 to 1965 in Oregon State University dairy herd. The use of records from five randomly selected daughters gave as good an estimate as was obtained when the records of all daughters were used for indexing dairy bulls. In comparison between the Regression Index and Herd-Mate Average, neither method gave a clear-cut estimate; the Regression Index tended to give an overestimate while the Herd-Mate Average tended to give an underestimate of a bull's transmitting ability. All indexes except the Herd-Mate Average for Holstein bulls failed to give an accurate estimate of the average actual production of the daughters. There was a significant difference between the Holsteins and Jerseys for both milk and butterfat production. Also, the three methods differed significantly from one another in the estimates of transmitting ability of sires.

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.

Download or read book Safety of Genetically Engineered Foods written by National Research Council and published by National Academies Press. This book was released on 2004-07-08 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.
Download or read book Animal Agriculture written by Fuller W. Bazer and published by Academic Press. This book was released on 2019-10-25 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. - Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management - Addresses the urgent issue of sustainability in modern animal agriculture - Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide

This book was released on 2013 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

Download or read book Muscle Hypertrophy of Genetic Origin and its use to Improve Beef Production written by J.W. King and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains the proceedings of a seminar held in Toulouse, France, on 10th, 11th and 12th June 1980, under the auspices of the Commission of the European Communities, Directorate General for Agriculture, Division for the Coordination of Agricultural Research, as part of a programme of research on beef production. The seminar was intended to bring together available experience on the utilisation of hereditary muscular hypertrophy for meat production in the member states of the European Communities. Although the phenomenon of double muscling has been exploited in various countries, particularly France, Italy and Belgium, different breeds are used and different methods of exploitation employed. An attempt was therefore made to bring together the collective experience of participants. Contributions ranged from those on the inheritance of muscular hypertrophy to alternative production systems and from fundamental studies of muscle growth to practical ways of selling the additional musrile found in animals with muscular hypertrophy. The collection of assembled papers and discussions thus represents one of the most extensive reviews of the subject that has been attempted.
