Establishing normal gut flora: a unique tool to help exclude undesirable bacteria in modern poultry production systems

Coccidiosis remains a major threat in poultry production, and live coccidiosis vaccines are gaining ground as a strategy to help reduce antimicrobial and coccidiostat use. However, growing evidence reports negative impacts of the vaccines on broiler performance. A pilot study explored the potential of a new yeast cell wall (YCW) supplement, OPTIWALL, to mitigate the […]

The poultry industry and scientific community acknowledge the interest of probiotics to sustain modern productions: for both zootechnical improvements and sanitary control, the use of live microorganisms is more and more routinely used in the field. Over the past two decades, literature has extensively documented the use of the probiotic Pediococcus acidilactici MA18/5M (Bactocell) in […]

As the laying cycle progresses, eggs get bigger while the hens’ calcium (Ca) metabolism becomes disrupted. The capacity to keep hens well beyond 90 weeks emphasizes the necessity to manage eggshell quality all along the cycle to avoid some end-of-lay disorders. All the Ca deposited on the eggshell comes from the feed. Therefore, its assimilation […]

Our calculation indicates that, even in the current high feed price context, LEVUCELL SB supplementation continues to be profitable through improved FCR and reduced mortality rates.
