B-Act Buzz: new formulation, same efficacy
Probiotics have their part to play in mitigating on-farm challenges, such as necrotic enteritis (NE) – even before these challenges reach a clinical stage.

ecrotic enteritis can be a massive challenge on farm, resulting in high mortality rates and reduced performance. Clostridium perfringens plays an im- portant role in the onset and development of NE
but there are multiple predisposing factors that need to be present before C. perfringens can lead to a clinical challenge. These factors can already adversely affect performance with- out presenting themselves as clinical issues. The develop- ment of dysbacteriosis (or dysbiosis) is one such factor, often described as a disruption of the microbiota’s homeostasis. Symptoms range from increased wet litter to reduced gut functioning, negatively impacting animal performance. Pro- biotics can help to prevent and mitigate such situations, both directly and indirectly.
Two-pronged approach Bacillus licheniformis DSM 28710 – the active strain in Huve- pharma’s B-Act range – is a good example of such a probiotic, tackling NE with a two-pronged approach. The first is based on preventing dysbiosis taking hold to start with, by making sure gut health is secure and the engine keeps running. However, if C. perfringens does proliferate and NE develops, B. licheniformis DSM 28710 is also capable of mitigating the negative effects of a NE challenge itself. The above was recently confirmed again in peer-reviewed research (Van der Veken et al., 2020), where broilers were sub- jected to an induced NE challenge. Health and performance parameters were recorded for three groups: a control, a B-Act group and an antibiotic treatment group. Even under the in- duced challenge, animals receiving B-Act scored significantly better than the control and to a similar level as the antibiotic treatment group. The trial also confirmed B-Act’s two-pronged approach: even before the NE challenge, animals supple- mented with B-Act already outperformed the control, simply through supporting and maintaining proper gut health.
Water soluble Probiotic inclusion in feed formulations has come under pressure lately though, as the current global situation has increased feed prices along the board. Fortunately, certain probiotics can also be added to drinking water. A flexible water-soluble formulation allows the probiotic to be applied only in specific periods. This does require adding a product to an already complex system and should be done with great care: water quality and management influence animal performance greatly, making the continuous availability of high-quality water paramount. As such, the probiotic formu- lation should be adapted to this – including the amount and type of carrier used. With this in mind, B-Act Buzz was developed as the newest member of Huvepharma’s probiotic range. The formulation is based on the same unique B. licheniformis strain as in other B-Act products, but is presented as an effervescent tablet. Each tablet weighs only 50 grams with adapted carriers for use in drinking water. In this way a minimal amount of carrier material is added to the water system while still ensuring efficient delivery of the probiotic. The tablet’s effervescence also offers greater ease of use compared to traditional pow- der products, as it requires minimal stirring and the probiotic spores are homogenously distributed throughout the water column. B-Act Buzz thus efficiently combines the highest water quality standards with practical on-farm efficacy in an easy-to-use tablet.
