Nutrinza Ultramin Sel-Gold is a soluble mixture designed to be administered to lactating dairy cows through the drinking water (troughs and in-line), via power drenching systems or mixed with feed. If this product is applied to feed (rather than dissolved and administered as a drench or in the water via a ‘dosatron’ of some form) then it should first be carefully mixed with 45g of a carrier to 5g of Ultramin Sel-Gold (ratio of 9:1) so that the combined application rate is 50g/ cow/day. The dose rate may be adjusted by a qualified nutritionist or vet depending on an assessment of herd’s current mineral status, and level of production being targeted. This is a soluble product suitable for water dispensers, drenching or applying via the feed. This option is mainly used during the facial eczema season.
