Book Description
This specially curated collection features four reviews of current and key research on heat stress in dairy cattle. The first chapter outlines technologies to breed for more heat tolerant dairy cattle, exploiting either between or within breed genetic variation in the trait. It discusses future perspectives on the use of different tools to achieve accelerated improvements of this important trait. The second chapter discusses breeding goals and multi-trait selection to balance production and non-production traits. It considers newer breeding objectives such as ensuring that cattle can adapt to a changing climate, including breeding for heat tolerance. The third chapter reviews challenges facing smallholder dairy farmers in Asia. These include the impact of high temperatures and humidity on milk yield, reproductive efficiency and animal health. The chapter places these challenges in the context of the broader economic constraints faced by smallholders and how they can be overcome. The final chapter highlights constraints in improving smallholder dairy production in Sub-Saharan Africa. Issues include developing breeds balancing yield with resilience to local climatic conditions. The chapter reviews ways of Improving breeding and productivity, as well as broader organisational support

Book Description
This specially curated collection features four reviews of current and key research on metabolic disorders in dairy cattle. The first chapter reviews the prevalence, etiology and effects of ruminal acidosis, as well as ways to counteract it through regulation of ruminal pH. The chapter includes a case study on subacute rumen acidosis (SARA) in the post-partum phase of the transition period. The second chapter assesses the main pathways for rumen fermentation which is a major factor in efficient transformation of nutrients. It discusses factors influencing the efficiency of microbial growth as well as the interactions between rumen energy and nitrogen metabolism in ensuring efficient digestion and avoiding metabolic disorders. The third chapter investigates the genetics of improving feed intake efficiency which has significant potential in reducing metabolic disorders. The chapter reviews key challenges in developing genomic selection indices for feed intake, including recording feed intake, pooling genetic data and establishing genomic breeding values for feed efficiency. The fourth chapter discusses how cereal grains impact feed efficiency in cattle. It reviews how cereal grains can be used to improve feed efficiency and the microbiology of cereal grain fermentation. The chapter also discusses ways of avoiding acidosis and other negative feed effects.

Book Description
This specially curated collection features four reviews of current and key research on mastitis in dairy cattle. The first chapter reviews the indicators of mastitis and the contagious and environmental pathogens which cause it. It then discusses how mastitis can be managed and controlled on dairy farms, including consideration of dry cow therapy and the use of antibiotics. The second chapter examines the impact of clinical and subclinical mastitis in cows on milk quality, and provides a detailed account of indicators of mastitis. It describes the impact of mastitis on milk composition and quality, addressing its effect on the protein, fat, lactose and iron content of milk. The third chapter reviews advances in dairy cattle breeding to improve resistance to mastitis. It includes sections on both conventional and new phenotypes for improving resistance to clinical mastitis and concludes with a section on increasing rates of genetic gain through genomic selection. The final chapter considers recent research on the prevalence and development of antimicrobial resistance in mastitis pathogens. It shows how consistent diagnostic protocols and recording systems, attention to medical history, appropriate choice of antibiotics and control of treatment duration can all contribute to minimizing unnecessary use of antimicrobials and promoting effective treatment of mastitis.
