Thanks for sharing this research. What where pharmaceutical levels of ZnO in the control diets used in the commercial trial in Denmark (figure 5)?

Dear Peter Ramaekers, thank you for your questions. The diets between the groups in this trial were standard Danish diets commercially available with 19.9% CP in the diet fed for the first 14 days. The only differences were the treatments, where the control group had 2,500ppm of ZnO during the first 14 days of the trial. The treatment group was supplemented with Actisaf and Safmannan during the first 14 days. The remainder of the trial period, only Actisaf was supplemented. Feed intake was not measured during this trial, hence feed costs per piglet or per kg growth could not be calculated.
