On 13 September 2017, more than 90 percent of Swiss feed producers attended the Provet Henry Schein seminar. This year's topic was „Moderne Futterzusatzstoffe in der Tierernährung - Stand und Perspektiven“ [Today’s feed additives in animal diets - state of the art and perspectives]. Attention was focused primarily on optimising the phosphorus and calcium content, as well as improvement of the efficacy of phytase using ACID BUF. At the end of the day there was a workshop regarding YUCCA PLUS, where we jointly discovered the interesting emulsifying properties, among others. We would like to thank all participants for their time and their contributions. Also, we are very grateful to Provet Henry Schein for the excellent organisation!
