A scientific experiment was conducted at Agricultural Institute – Shumen, with growing pigs of the Danube White breed. In order to achieve the set goal, two groups were formed - control (I group) and experimental (II group) of 21 pigs each or a total of 42 pigs. The animals were reared in group pens of 7 pigs each. The pigs from both groups were selected and matched in gender and live weight. The experiment began at a live weight of 9,800 - 9,957 kg and ended at a live weight of 28,657 - 29,253 kg. The addition of an aqueous extract of nettle at a dose of 2 ml per animal per day in growing pigs did not significantly affect the growth abilities and feed utilization. Regarding the indicators related to the blood count, an increased concentration of hemoglobin, an increased number of erythrocytes and leukocytes and increased levels of creatine kinase were observed, within the physiological norms in the pigs from the experimental group, but they are insignificant and unproven and can only be accepted as a trend.
