Резюме: Two experiments with growing pigs from Danube white breed were carried out. Each of the experiments is comprised of 48 animals, divided into two groups, starting at 9.348–9.533 kg and ending at 26.583–36.214 kg live weight. Groups were equaled by number, sex, origin and live weight in both of the trials. The aim of the present study was to investigate the effect from the addition of ProPen H in compound feed on the growth intensity, feed conversion and health of growing pigs. ProPen H is a Polish product from ETOS – Poland. ProPen H is dehydrated copper sulfate used as a substitute for ZnO in the post-weaning period. The product was used in dose 1.3 kg/t, providing 165 mg Cu/kg feed. Experiments were carried out by the following designs:
First experiment:
І group – control: ZnO 3 kg/t feed – till 14 days after weaning;
ІІ group – experimental: Propen H – 1300 g/t feed – whole experimental period.
Second experiment:
І group – control: Kolestin 1 kg/t + ZnO 3 kg/t – 3000 ppm – till 21 days after weaning; from 21 to the end of the trial – compound feed without addition;
ІІ group – experimental: Kolestin 1 kg/t + ProPen H 1.3 kg/t – till 21 after weaning; from 21 to the end of the trial – ProPen H 1.3 kg.
In the present study it was established that replacing ZnO with the addition of dehydrated copper sulfate (ProPen H) in compound feed for growing pigs did not influence in growth rate and feed inversion ratio.
