“One year we sent 60 out of our 190 cows to the works. On a farm this size it just wasn’t sustainable! It wasn’t until we spoke to our Nutritech Area Manager that we discovered some of our problems could be due to a simple mineral or trace element deficiency on our farm”. Liver biopsies and soil and water samples showed that the Jellyman’s cows were suffering from an acute deficiency in copper and selenium. Now the Jellymans drench their cows with FloCalMag® and FloCal® (for extra calcium) post calving for 100days and with FloZinc® during the eczema season. The Jellymans make the cost of their Nutritech mineral program back in production alone. “If we were to factor in the improvement in animal health plus the improvement in conception rates we could afford to pay more for the product and still make a profit by using it!”
