• a colostrum heating tub, where said colostrum heating tub is adapted for holding:
• a stationary pool of heating liquid, such as water, provided within said colostrum heating tub, and surrounding said container, wherein said stationary pool of heating liquid is maintained at a uniform temperature;
• and
• said container, such that it is at least partly immersed in said heating liquid when positioned in said colostrum heating tub;
• wherein said colostrum heating tub further comprises a rack module for holding at least said container within said stationary pool of heating liquid, wherein the rack module is adapted for rotating around an axis aligned through the center of said rack module, such that at least said container can be rotated 360 degrees around said central axis, such that said container is, at all times during said 360 degree rotation around said central axis in said rack module, maintained in a fixed position with respect to said rack module and at least partly immersed in said stationary pool of heating liquid for even distribution of heat throughout said container to uniformly heat said colostrum;
