This book was released on 2011-10 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bangladesh has one of the highest densities of livestock in the world with 145 large ruminants per square kilometer. Dairy is the most important sector of livestock industry in Bangladesh that provides greater part of animal source protein for human consumption. Lifetime productivity of cows largely depends on their individual reproductive performance. In most countries, the primary objective of a reproductive control program in a dairy herd is to have each cow calve and produce a live calf in every 12 months. Like in many other countries, poor reproductive efficiency has been considered to be the major limiting factors in medium and large scale market oriented dairying in Bangladesh for achieving this goal. This book highlighted the overall reproductive efficiency in main milk pocket area of Bangladesh combining both traditional and recent measures of reproductive indexes.

Download or read book Reproduction in Cattle written by Peter J. H. Ball and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Reproductive inefficiency is a significant problem facing modern dairy herds. The research herein discusses issues related to reproductive efficiency of dairy herds in three distinct sections. The use of electronic herd records is an important component of troubleshooting a herd's reproductive performance. Herd record analysis must be coupled with a herd visit and clinical examinations of individual cows to try to identify factors that are limiting reproductive success. One component of this document describes methodology for monitoring reproductive performance of dairy herds and possible reasons for reproductive failure. While reproductive inefficiency is costly to dairy producers, loss estimates vary because of the conditions under which they are evaluated. Another aspect of this research has been the development of a model to be used for estimating economic effects of changes in reproductive performance under specific situations. It is shown that the magnitude of economic effects are sensitive to market prices faced by dairy producers as well as the herd's current level of reproductive performance. A very common management problem limiting reproductive efficiency in Ohio dairies is the failure to efficiently and accurately detect estrus. A novel approach to the estrus detection problem currently being offered to Ohio dairies is for producers to contract estrus detection activities and breeding decisions to outside parties. A field study involving 32 herds was conducted in order to evaluate the efficacy of such a reproductive management program. At the start of data acquisition, 16 of the herds were enrolled in the management program; two non-program herds began using the program and two program herds stopped using the program during the data acquisition phase. Electronic reproductive data was collected for at least 18 months on all participating herds and analyzed. Results indicated that the program was associated with statistically significant improvements in some aspects of reproductive performance. The program did not appear to affect economic performance.

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 558 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

Download or read book Instant Insights Infertility Other Rep written by Alexander C. O. Evans and published by . This book was released on 2022-08-23 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection features four peer-reviewed reviews on infertility and other reproductive disorders in dairy cattle. The first chapter discusses the physiology of the main impediments to fertility and management issues that need to be addressed to ensure good fertility of dairy cows. The chapter focusses on parturition and uterine health, the importance of the post-partum environment and the role of oestrus, as well as methods of establishing pregnancy and the effect of heat stress on cows' fertility. The second chapter considers recent developments in automated monitoring of livestock fertility and pregnancy, focussing on its implementation in dairy cattle production. The chapter explores the physiological basics of the reproductive cycle in dairy cattle and the use of artificial intelligence to monitor and report changes in animal behaviour. The third chapter reviews progress in understanding the role of genetics in addressing the decline in fertility rates in dairy cattle. The chapter discusses strategies to improve the reproductive performance of dairy cattle, including the use of different breeds, measures of fertility and genomic data. The final chapter reviews best practices to detect reproductive problems and limitations in dairy cattle. The chapter identifies key areas which are known to limit performance and provides strategies which can be implemented to optimise reproductive performance and maximise animal health.
