A scientific experiment with twenty fattening pigs from the Danube White breed was conducted in Agricultural Institute - Shumen. The animals were separated into two groups of ten, and were fed and reared in individual boxes. The experiment began with an average live weight of 55.300 kg for the control group and 55.800 kg for the trial group. Throughout the rearing period, the animals received compound feed containing 15.5 g Crude Protein (CP), 0.71 g Lysine, 0.67 g calcium and 0.60 g phosphorus. To the feed of the experimental group were added herbal supplements 20 g/per capita daily with the following composition: 50% rosehip flour, 30% nettle leaves, 10% weeds grass, 5% dandelion, 5% hawthorn. The aim of this experiment was to establish the influence of herbal supplements on the productivity, slaughter qualities, chemical composition and physical properties of m. Longissimus dorsi meat in fattening pigs. In conclusion, we established that the herbal supplement has influenced the fat thickness in the shoulder (30.00 mm and 19.40 mm, P=0.027) and back (17.40 mm and 32.00 mm, P=0.016).
