Progress was one of the speakers in the livestock stage at the event and he talked about the relationship between the spread of African Swine Fever and feed. According to Vin- cent, there is definitely a relationship; however, the connec- tion between feed and the ASF virus differs from country to country: “Feed can play a role in the spread of ASF, mostly when production is fairly basic. If the use of swill, forage or plasma is not done professionally, this could be a risk. When swine production is professionalised, these effects wouldn’t occur.” On the other hand, feed could also play a role in solv- ing the ASF problem, mainly when it’s part of a bigger strat- egy on biosecurity and vaccination. Above all, emphasises Vincent, human behavior is key in both the spread and the strategy. “If the farmers and industry are aware of what kind of virus it is, what it does and doesn’t do, that would help a lot in combating it. And for that reason I think that knowl- edge sharing and transparent, immediate reporting about outbreaks is essential.”

Animal nutrition in an antibiotic free era Besides sustainability and feed safety, animal health was a re- curring topic during the All About Feed Forum. Nowadays, our livestock can be seen as Olympic athletes and the ques- tion is how to keep our highly productive livestock healthy. Feed plays a major role in the wellbeing of animals and the reduction of antibiotic use the last years requires new in- sights and solutions in the field of animal nutrition. Walter van Hofstraeten, senior consultant poultry nutrition at Scho- thorst Feed Research, talked about poultry feed formulation in an antibiotic free era. He highlighted the effect of several nutrients in poultry diets: “When you don’t use antibiotic growth promotors (AGP) in the diets it is important to reduce

gut viscosity, by the use of NSP degrading enzymes. Secondly it is important to use good digestible fat sources that are rich in MCFA, such as coconut oil. Thirdly, recent research has shown that it is positive to use some inert fibre sources and to avoid too much fibre from fermentable sources.” In the case of protein, Walter suggests reducing the use of in- digestible protein and a lower dietary crude protein level. Looking to the future, when it could be necessary to reduce dietary protein, synthetic amino acids may become more im- portant. Walter: “Mostly the number of different amino acids used will increase.”

With more than 20 speakers presenting, the Virtual All About Feed forum was a informative and successfull event and we hope you enjoyed this first edition. The digital event brought to- gether many professionals from the industry and we would like to thank all participants and partners for joining.
