Iodine
Iodine levels are poor in grass and even lower in maize and whole crop. Therefore iodine needs to be provided almost every day. Calves born to iodine-deficient cows may be stillborn, with goitre and areas of alopecia and subcutaneous oedema. Weak calves are unwilling to suck causing high perinatal mortality. As with selenium, iodine deficiency has also been implicated in poor growth rates, poor milk production and retained placenta.
Manganese
Important for fertility, notably ovulation and development of the embryo in its early stages. Most recently manganese has been shown to have a protective role for the embryo in the early stages of cell division.
Cobalt
Supports Energy Metabolism, appetite and thrive.
