Cows put their own calcium into milk – more than half of mature cows have subclinical hypocalcemia
The demand for calcium from cows to enrich colostrum is highest at calving. This is because cows are literally drawing from their own calcium stores to put the mineral into the milk. The result is often a negative calcium balance that occurs before the mechanisms to pull calcium from the cow’s skeletal system get activated. Calcium homeostasis is fragile around calving time. … [Read more...]

Colostrum, more than just immunoglobulins (webinar video)
Colostrum is important to all mammal newborns. It is essential for the final development and maturation of the gastrointestinal tract and immune system.
