This collection features five peer-reviewed reviews on dietary supplements in dairy cattle nutrition. The first chapter addresses the manipulation of rumen fermentation to maximise the efficiency of feed utilisation and increase ruminant productivity. It considers a wide variety of approaches, including the use of dietary buffers. The second chapter reviews the use of probiotics as supplements for ruminants to promote digestive efficiency and productivity. The chapter summarises the benefits and modes of action of probiotics, as well as their role in optimising feed efficiency and reducing methane production. The third chapter considers the beneficial roles of plant secondary compounds in sustainable ruminant nutrition. It describes the effects and composition of the three major groups of plant secondary compounds: essential oils, tannins and saponins. The fourth chapter discusses the growing need for alternative feed sources as a result of increasing demand for meat and dairy products. The chapter reviews the nutritional composition of seaweed and introduces it as a potential novel protein supplement in animal feeds. The final chapter evaluates the role of macroalgae as a potential anti-methanogenic ruminant feed resource and reviews its impact on animal production and performance.

I've been a comic book fan since childhood. The child became a man and the fan became a comic book retailer. I wanted more out of life and joined the San Diego Police Department in my mid-20s. I retired after a 20-year stint and returned to comic book collecting and retailing as a full-time job. I re-entered that world wide-eyed, but was shocked to see how much corruption and scamming took place in my hobby. I conveniently found that my legal skills borne from police work gave me the tools to help victims of the flagrant rip-offs happening everyday in the comic book world. I've worked with crime victims and police departments to solve comic book-related crimes and recover stolen comics for the victims. The Forensic Comicologist is both a play on words and a proper description of the science of collecting comic books. To add credence to my book I spend a few chapters delving into the history of comics, coupled with the history of collecting those comics. I include relevance to explain why some comics are popular and others are not. My book is a tutorial on how to collect wisely and reduce risks. I've included colorful anecdotes and memoirs from fan-friends of mine. The job of my book is to de-mystify comic book collecting for novices and explain why things are the way they are.
