Technical Considerations

Livestock industry and organization for animal wellfare underlie the need for drug and nutrient delivery systems for ruminants that protect active ingredients from ruminal fermentation. To deliver drugs or nutrients directly to the small intestine for absorption, therapeutical systems must meet the safety and cost criteria. An effective post-ruminal delivery system is a prerequisite to implement some significant advances in animal nutrition and health in ruminants. Comparing with the products developed for human use, cost constraints have impeded the development of effective post-ruminal delivery systems and rumenstable products. This article outlines physiological and technical considerations encountered in the design of effective post-ruminal delivery systems. The requirements and formulation of a pH-dependent rumen stable coating systems and possible future developments will be discussed.

Scientific Achievements

From my senior school days, I had wanted to pursue a career in food. In quite what capacity I was not too sure. So my starting points were within the fields of animal nutrition before moving for the major part of my career to medical schools to study human nutrition and health. My career scientific achievements lie within the Kuhnian spectrum of normal science, but within that normality, I was always one to challenge conventional wisdom. An academic career is about more than just research. It is about teaching and not just the minutiae of nutrition, but about life and living, about challenges and failures. Reflecting on the experience of that career, my advice to early stage researchers is this: Be patient, determined, and resilient in the very early stages. Hold no fear of change and be courageous in challenging conventional wisdom. Always favor openness and collaboration and always seek to help others. Citation indices are important to your career, but these other avenues that I advise you to follow are what you will eventually be most proud of.

This review provides a summary of recent research on biomimetic and bioinspired strategies applied in the field of biomedical material engineering and focusing particularly on calcium phosphate—protein template constructs inspired by biomineralisation. A description of and discussion on the biomineralisation process is followed by a general summary of the application of the biomimetic and bioinspired strategies in the fields of biomedical material engineering and regenerative medicine. Particular attention is devoted to the description of individual peptides and proteins that serve as templates for the biomimetic mineralisation of calcium phosphate. Moreover, the review also presents a description of smart devices including delivery systems and constructs with specific functions. The paper concludes with a summary of and discussion on potential future developments in this field.

The use of probiotics for farm animals has increased considerably over the last 15 years. Probiotics are defined as live microorganisms which can confer a health benefit for the host when administered in appropriate and regular quantities. Once ingested, the probiotic microorganisms can modulate the balance and activities of the gastrointestinal microbiota, whose role is fundamental to gut homeostasis. It has been demonstrated that numerous factors, such as dietary and management constraints, can strongly affect the structure and activities of the gut microbial communities, leading to impaired health and performance in livestock animals. In this review, the most important benefits of yeast and bacterial probiotics upon the gastrointestinal microbial ecosystem in ruminants and monogastric animals (equines, pigs, poultry, fish) reported in the recent scientific literature are described, as well as their implications in terms of animal nutrition and health. Additional knowledge on the possible mechanisms of action is also provided.
