The Teklad 2018SX Global 18% Protein Extruded Rodent Diet (15 kg) is a premium, fixed formula diet designed to optimize nutrient delivery for reproductive and growing rodents. Its unique formulation excludes alfalfa meal to minimize chlorophyll and phytoestrogen levels, while the absence of fish meal lowers nitrosamine risk. Autoclavable and extruded for minimized clumping, it ensures consistent nutrition even post-autoclaving, making it an ideal choice for research settings.
