all over Iowa | It could be the water. I had a client that has a pasture on reclaimed coal ground with a creek running through it. He was having 20-30% open cows for several years. On our suggestion he did liver biopsies to check TM status. The cows were all in excellent body condition. We adjusted the trace mineral levels with some organic TMs in his supplement, and he ran water lines to Cobetts in the pasture. Last year he ran 10-15% open, and this year the open cows were in the 6-8% range in all 3 groups. |
