ISSUE FOCUS 46 FEED & ADDITIVE MAGAZINE March 2025 particles on the top (largest) screen may indicate improper rumination or a too fast rumen passage rate. Manure washing results show that bulls supplemented with live yeast (Biosprint®) had more residue in the smallest particle size distribution and significantly less feces, with a coarse particle size distribution collected in the top screen (Figure 3; P = 0.008). Since smaller particles in the feces point to better digestive ability to break down fiber, these results indicate improved rumen health and digestive capacity. The groups supplemented with live yeast received numerically better carcass scores than the control groups, with all carcasses graded in the higher-quality categories. Optimized feeding and nutrient supply are critical for good carcass quality. Therefore, supplementation with Biosprint® resulted in a positive return on investment due to improved carcass scores and increased carcass weights. Biosprint® live yeast has been shown to support fattening bulls by improving rumen health and functionality. This positive effect was seen in improved DWG and FCR, and better digestibility. Ultimately, this digestive support resulted in improved carcass quality and a positive return on investment. About Dr. Melinda Culver Dr. Melinda Culver is a veterinarian with a strong interest in animal health and nutrition. After earning her Doctor of Veterinary Medicine degree in 2004, she pursued a Ph.D. in Animal Science at Washington State University (2006), focusing on muscle and fat cell development. Dr. Culver transitioned from veterinary practice to the supplement industry, where she's spent over 15 years using her knowledge to improve animal and human well-being through advancements in nutrition. She joined Biochem in 2022, bringing her extensive experience to the team. About Andrea Remmersmann Andrea Remmersmann completed her bachelor's degree at Osnabrück University of Applied Sciences in the field of industrial engineering in agribusiness. She obtained a Master in Agricultural Sciences at the Christian-Albrechts-Universität zu Kiel. Her research focused on climate management and phosphorus-reduced feeding strategies in dairy farming. Since June 2019, Andrea Remmersmann has been the R&D Application Manager responsible for yeast-based pre- and probiotic products. Figure 3. The results of manure washing. More fine and less coarse particles are seen in the feces from bulls supplemented with Biosprint® compared to control bulls.
