Reproduction in Cattle
Author: Peter J. H. BallPublisher: John Wiley & Sons
ISBN: 1405148012
Category : Medical
Languages : en
Pages : 248
Book Description
Cattle play a fundamental role in animal agriculture throughout the world. They not only provide us with a vital food source, but they also provide us with fertilizer and fuel. Keeping reproduction levels at an optimum level is therefore essential, but this is often a complicated process, especially with modern, high yielding cows. Written in a practical and user-friendly style, this book aims to help the reader understand cattle reproduction by explaining the underlying physiology of the reproductive process and the role and importance of pharmacology and technology, and showing how management techniques can improve reproductive efficiency. This edition includes: Recent research findings on the physiology of the oestrous cycle and its control; New techniques for monitoring and manipulating reproduction, including pregnancy diagnosis and embryo transfer; Advice on identifying common infertility problems and how to prevent and treat them. Reproduction Cattle 3e is essential reading for veterinary and agricultural students, as well as veterinarians and farmers involved in cattle reproduction.

Book Description
"Breeding Focus 2021 - Improving reproduction" is the fourth workshop in the series. The Breeding Focus series was developed to provide an opportunity for exchange between industry and research across a number of agricultural industry sectors. Reproduction is a main economic driver for profitability and genetic gain. Successful reproduction is a complex characteristic comprising the formation of reproductive cells, successful mating and fertilisation, embryonic and fetal growth and eventually a successful birthing event. In livestock species, reproduction traits have mostly low heritabilities, which makes it challenging to improve reproduction as part of a multiple trait breeding objective. The complexity arises not just from the cascade of processes required to result in successful reproduction, but the relevant traits are different in males and females and they are influenced through health and fitness, nutrition, climate and other environmental and management factors.
Economic Aspects of Animal Breeding
Author: Joel Ira WellerPublisher: Springer Science & Business Media
ISBN: 9780412597503
Category : Technology & Engineering
Languages : en
Pages : 280
Book Description
This important book covers economic evaluation of genetic differences in animals, determination of breeding goals within an economic context and economic evaluation of breeding programs. During the last 50 years there have been great advances made in the breeding of domesticated animal species. Most of this work has been achieved through the efforts of geneticists, and often the economic goals of such advances have not been clearly evaluated. Economic Aspects of Animal Breeding redresses the balance and provides a much needed synthesis of this most important subject. The book is divided into five sections: basic concepts; economic evaluation of genetic differences; advanced topics in selection indices; economic evaluation of breeding programs, including biotechnological aspects; crossbreeding and heterosis.
Nutrition and Lactation in the Dairy Cow
Author: Philip C. GarnsworthyPublisher: Elsevier
ISBN: 1483100189
Category : Technology & Engineering
Languages : en
Pages : 442
Book Description
Nutrition and Lactation in the Dairy Cow is the proceedings of the 46th University of Nottingham Easter School in Agricultural Science. Said symposium was concerned with the significant advances in the field of nutrition and lactation in the dairy cow. The book is divided in five parts. Part I deals with the principles behind nutrition and lactation of cows. Part II discusses the cow's nutrient interactions; responses to nutrients that yield protein and energy; and the influence of nutrient balance and milk yields. Part III tackles the efficiency of energy utilization in cows and its relation to milk production. Part IV talks about food intake of cows and the factors that affect it, while Part V deals with the different feeding systems for cows. The text is recommended for those involved in raising cows and dairy production, especially those who would like to know more and make studies about the relationship of nutrition and lactation of cows.
Periparturient Diseases of Dairy Cows
Author: Burim N. AmetajPublisher: Springer
ISBN: 3319430335
Category : Science
Languages : en
Pages : 281
Book Description
This book summarizes the results achieved so far by application of various biological systems (including genomics, transcriptomics, proteomics, and metabolomics) involved in the pathomechanisms and early diagnosis of periparturient diseases as specific biomarkers of disease in cattle. These emerging technologies help to extensively enhance our understanding of the etiology and pathogenesis of periparturient diseases of transition dairy cows. The book includes a chapter dedicated to ‘omics’ sciences and one that discusses the myths established in animal and veterinary sciences in recent decades and emerging, new paradigms. The diseases discussed include metritis, mastitis, laminitis, ketosis, rumen acidosis, periparturient immunosuppression, gastrointestinal microbiota and their involvement in disease, infertility, fatty liver, milk fever, and retained placenta. This book is intended for academics, veterinarians, animal nutritionists, researchers, and graduate students working in the field of ‘omics sciences’ with a special interest in dairy cattle health.
