Genetic Improvement of Meat Quality Traits in Pigs

Book Description
Four projects were conducted to investigate intramuscular fat percentage, an important pork quality trait, its measurement in live swine, estimation of genetic parameters, and determination of its relationship with carcass, meat, and eating quality traits, and implementation of this trait into a selection experiment to improve the trait. In the first project, purebred Durocs were used to develop a model using real-time ultrasound technology to predict loin intramuscular fat percentage of the longissimus muscle in live pigs. In the second project, data from two national progeny testing programs were used to compare the relationships of intramuscular fat percentage of the longissimus predicted using real-time ultrasound and chemical intramuscular fat percentage with meat quality traits in pigs. In the third project, data from a selection project designed to increase intramuscular fat percentage (IMF) in a Duroc swine population were utilized to compare three different models used to estimate breeding values for IMF. In the final study, data from randomly mated and selected Duroc pigs were used to determine the genetic and phenotypic relationships between individual subcutaneous backfat layers and intramuscular fat percentage of the loin. Overall, the results from the four projects contained in this thesis indicate measuring intramuscular fat percentage of the porcine longissimus can be accurately performed utilizing real-time ultrasound; the genetic parameters and relationships with other meat and eating quality traits for IMF predicted from real-time ultrasound are similar to those of IMF estimated from the carcass; and substantial genetic progress can be made when implementing this technology into a selection program. In addition, inclusion of a single backfat layer into the genetic evaluation for intramuscular fat percentage could increase in the amount of genetic progress realized through selection.

Animal Breeding and Genetics
Author: Matthew L. SpanglerPublisher: Springer Nature
ISBN: 1071624601
Category : Medical
Languages : en
Pages : 421
Book Description
This newly updated and revised volume of the Encyclopedia of Sustainability Science and Technology (ESST) details the role of Animal Breeding and Genetics in the sustainability of animal agriculture. The volume covers scientific principles and applications includes the current science used to advance cattle, poultry, swine,sheep, and equine populations, as well as the future role of techniques such as gene editing. International leaders in the field explain foundational concepts such as heritability, the covariance between relatives, statistical approaches to predicting the genetic merit of individuals, and the development and advancement of molecular techniques to elucidate changes in the DNA sequence that underly phenotypic variation. The use of genetic-based tools to improve animal agriculture and meet consumer demands across species is treated in detail. Readers will gain an understanding of how global livestock producers have implemented advanced genetic selection tools and used them to improve reproduction, production, efficiency, health, and sustainability. The interactions of genetics and production environments, and the genetic components of the complex interactions among animals are also discussed. The future of Animal Breeding and Genetics, including the challenges and opportunities that exist in feeding a growing world population, are addressed.
Feed efficiency in swine
Author: John F. PatiencePublisher: Springer Science & Business Media
ISBN: 9086867561
Category : Science
Languages : en
Pages : 264
Book Description
'Feed efficiency in swine' has been prepared as a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.
