First microbial authorised for liquid feed hygiene GB 

Lallemand Animal Nutrition is pleased to announce that its unique lactic acid bacteria strain Pediococcus acidilactici CNCM I-4622 (BACTOCELL) has become the first microbial to receive an authorisation in Great Britain related to the hygiene of liquid feed. 

Already the first microbial to receive EU authorisation related to the hygiene of liquid feed for all species¹, the probiotic has now received the same recognition from the Food Standards Agency (FSA) for use in all liquid-fed livestock in Great Britain².  

“We’re also seeing increasing amounts of milk replacer and porridge being fed to piglets, as a result of larger litter sizes, and the hygiene of these feeds is also very important at this time.

“Producers who have been benefitting from feeding Bactocell to growing and fattening pigs can now include the probiotic in liquid feed fed to all classes of pigs, with this new authorisation – making it much easier to implement a consistent feed hygiene strategy across the herd.” 

Mr McFarland says ensuring the sanitary quality of liquid feed and the feeding system itself is a key priority for all producers.  

He adds that Bactocell is recognised by both the European Food Safety Authority (EFSA) and the UK government’s FSA for its safety, potential to reduce pH, and ability to limit the growth of coliform bacteria in liquid feeds. 

“The unique bacteria strain is now authorised as a technological feed additive within the functional group of ‘hygiene condition enhancer – acidity regulator’,” he explains. 

 “Trials have shown that feeds containing the strain were better and faster acidified than untreated feed.  

“Feed pH remained significantly lower for up to 24 hours and the concentration of L-lactic acid in the feed was significantly higher with P. acidilactici CNCM I-4622 included.” 

Mr McFarland explains that by converting non-digestible carbohydrates into L+ lactic acid, this promotes a healthier bacterial balance. 

“The probiotic helps maintain the nutritional quality of liquid feed, preserving lysine levels, and reduces the colonisation of harmful bacteria contributing to negative biofilm formation,” he adds. 

Mr McFarland says farmers who adopt Bactocell into their feeding practice may also observe animal performance improvements linked to gut health. 

“This unique lactic acid bacteria can survive throughout the gut and plays an important role in microbiota balance, intestinal system maturity, and digestive efficiency,” he adds.  

“Its benefits can be particularly noticeable and deliver significant economic returns under challenging conditions such as bacterial diarrhoea caused by sub-optimal feed hygiene practices.”
