AgImports Products include trace minerals in almost all of their supplements. Copper, Cobalt, Iodine, Selenium and Zinc are all important for various functions. It can be difficult to identify these deficiencies individually so the simplest way is to include them all in the mix.
Copper deficiency may be a cause of poor fertility and can also cause ‘sway back’ in lambs. Copper is important in wool for mechanical strength. Copper eficiency may cause poor pigmentation in cattle and horses.
Cobalt is important in the formation of haemoglobin. Cobalt deficiency causes poor growth in lambs and
calves and they can become anaemic.
Iodine deficiency may be manifested by general weakness and animals may be born blind, hairless or dead. Iodine deficiency affects quality and quantity of wool growth.
Selenium deficiency causes muscular degeneration (White Muscle Disease) in calves and lambs. Selenium deficiency can also cause retained afterbirth. Selenium deficiency also restricts wool growth.
Zinc deficiency causes reduced feed intake, poor growth rate and cracks can occur in the hooves. Wool may loose its crimp and fall out.
Bighead is a condition horses may develop when grazing improved pasture. It often occurs in Buffel pasture, but may also occur with Kikuyu or Setaria. It is caused by the oxalic acid in the grass which “ties up” the calcium, creating a calcium deficiency in the horse. The problem is often worse when the pasture has fresh growth. It can be managed by providing a calcium supplement to all horses grazing these types of pasture.
