The aim of study was to evaluate the influence of biologically active additives on the hormonal status of lactating sows and the absolute growth of suckling piglets. Glutam 1M, nanoaquachelates of germanium (NPs-Ge) and Quatronan-Se (Cu-NPs, Se-NPs, Cr-NPs, Ge-NPs, Mn-NPs) have been administered orally (lat. per os) for animals in different percentage doses and schemes. Five animals groups have been formed by the method of analogues: control (20 ml physiological solution) and four experimental (group M: 18 mg/kg Glutam 1M; group G18: 5 μg/kg Ge-NP + 18 mg/kg Glutam 1M; group G9: 5 μg/kg Ge-NP + 9 mg/kg Glutam 1M; and group Q: Quatronan-Se (0.02 ml/kg) administered for 14 days). Results showed positive effects of the use of supplements on prolactin secretion. Administration of 5 mg/kg live weight NPs-Ge for sows G18 and G9 for 4 days before the farrowing increased the level of prolactin in the blood serum. On farrowing day, the hormone level in these groups was 14.6 ng/ml (G18) and 13.42 ng/ml (G9), while in K and M groups it was 12.02 and 9.94 ng/ml, respectively. On the day of weaning, the highest prolactin content has been observed in the G18 group as 14.9 ng/ml. Also, suckling piglets from this group have had the highest growth during the studied period. During the entire suckling period, the growth of piglets in the G18 group was 3.65 kg and was higher compared to the K (2.94 kg), M (3.58 kg), G9 (3.31 kg) and Q (3.44 kg) groups. It’s suggested that the scheme introduction of Germanium (5 mg/kg) additives, 4 days before and 10 days after farrowing + Glutam 1M (18 mg/kg) 3 days after farrowing is the most effective (group G18) in means of growth performance.
