World-leading experts discuss at Lallemand-sponsored University of Bologna symposium

On May 12th, took place in Bologna, Italy, a scientific symposium dedicated to the role of plant fibre in dairy production, organized by University of Bologna with the support of Lallemand Animal Nutrition and Filozoo Italy.

Titled:  "Fibre: a key element for dairy production profitability?", this event, featuring world-leading experts in dairy nutrition and microbiology: Prof. Formigoni from University of Bologna, Prof Sniffen (ex-Cornell), Prof Mertens (Mertens Innovation & Research), Dr Bach (IRTA), and Dr Chaucheyras-Durand (INRA-Lallemand), and Chaired by Professor Savoini from University of Milan, attracted over 300 participants from all over Italy as well as 24 different countries around the world. Offering a good combination of high level scientific content and practical field recommendations delivered by top-notch scientists in the field, the symposium generated rich and enthusiast discussions, and will certainly lead to the development of new feeding strategies and herd management practices. 

In today's economic and climatic context, the trend is to increase the proportion of fibrous ingredients in ruminant diet and it is crucial to be able to extract the maximum of energy and nutrients from this fibre fraction, in order to increase Income Over Feed Cost (IOFC). In this setting, it is important to have a better understanding of fibre digestion and utilization by ruminants, and the factors that affect this. These factors, as we have learned from the experts present in Bologna, go beyond the diet and include non-dietary factors (the animal development at earlier stage, its feeding behaviour etc.), as well as environmental factors which affect what is commonly referred to as fibre quality (draught, temperatures, plant maturity...).

These factors were translated into certain very practical recommendations meant to optimise fibre digestibility and thus increase the IOFC. We have compiled these recommendations in a document that shall be available to nutritionists and farmers. Among feeding strategies discussed in Bologna, the use of ruminant specific live yeast was mentioned by several speakers. Indeed, ruminant specific yeast SC I-1077 (Levucell SC) increases fibre digestion, enhancing the nutritional value of forages. This highlights the fact that Ruminant specific yeast benefits can go beyond rumen health and pH stabilization, it can help extract more energy from the diet and improve feed efficiency.
