Red Rockies® outsell all other licks in the UK with the exception of our own Chelated Rockies®. More intensive grazing, reseeding with new leys and heavier fertilising have led to more trace element deficiencies especially of copper. COPPER - needed for growth, bone development, fertility and especially in young cattle, coat condition. Mild deficiencies are common, but may be difficult to detect even though cattle are not performing at their peak. Growing cattle, dairy cows and sucklers on improved pastures will all benefit from the full balance of trace elements including copper, supplied in a Red Rockie®.
