Understanding the factors that inform their decision to eat is therefore critical when formulating diets. Find out on pages 27-28.
While yeasts have been fed to animals for over 100 years due to their nutritional richness and reported effects in supporting health and growth performance, Pichia guilliermondii is a relatively novel type of yeast with promising potential for use in swine feed applications. Find out the details on pages 24-25.

Particle size influences feed efficiency and gut health in pigs. With an increased focus on the complex interaction between pellet characteristics, gut health and microbiota, feed processing needs to evolve. See pages 52-53.
With the imminent ban of pharmacological levels of zinc in the EU, is zinc off the table entirely, or can it be used in smarter ways? The article on pages 54-55 explores the answers.
At the Global Feed Safety Summit held in April, Roland van der Post, host and GMP+ MD, urged the attendees: ”We cannot take feed safety for granted. We have to keep developing our safety control schemes and we have to be prepared for the demands beyond tomorrow.” Read more on pages 57-58.
