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.
