ISSUE FOCUS 50 FEED & ADDITIVE MAGAZINE March 2022 tersorb Premium/animal/day increases milk yield and improves milk quality by decreasing somatic cell count. Adsorbing substances contained in Mastersorb Premium tie up the LPS produced in the rumen in different cow lactation phases. Typically, the rise in the level of somatic cells in milk depends on etiological agents such as Streptococcus spp, Staphylococcus spp, mycoplasma, and more. LPS stress is not the sole agent responsible for raising somatic cell counts, but also other factors among which: • Lactation stage and age of the animal • Season of the year (in summer the problem is increased) • Milking plant (proper maintenance) • General management and nutrition However, by reducing the level of LPS, Mastersorb provides an important aid to decrease somatic cell count. PERFORMANCE IMPACT We know how issues like ketosis, mastitis, and laminitis affect cow health and performance. However, less visible issues such as LPS (endotoxins) can also result in poor health. A healthy rumen with optimized SCFA composition, microbial balance and with optimal functioning intestinal walls leads to less energetic wastage. Health problems which come to the surface may be caused by underlying factors, such as suboptimal rumen functioning and high concentrations of LPS. Phytogenics and mycotoxin binders can help to improve rumen function, the bound LPS resulting in improved gut health and better dairy cow performance. Figure 5.

Effect of Mastersorb Premium on somatic cell count About Claudio Campanelli Claudio Campanelli graduated from the Agricultural Sciences Faculty of the University of Milan, with a specialization in zootechnics. His thesis focused on the energy metabolism of ruminants fed diets with different caloric intakes. Following a Master's degree at the Zooprophylactic Institute, he began his professional career first as a technician nutritionist and later as a commercial technician for the dairy cattle sector. He is EW Nutrition’s technical manager for dairy cattle and small ruminants in Europe.
