The aim of the study was to determine the influence of the addition to mixed fodder compouds containing fumaric acid, formic acid, orthophosphoric acid and flavomycin on the productive effects of piglets aged up to 60 days. The experimental was carried out on 30 piglet litters divided into 6 experimental groups. Group I was regarded as a negative control in which the animals did not received any supplements of stimulating activity. The piglets of group II, III, IV, V and VI were given the same fodder with different supplements of ergotropic type, i.e. group II - flavomycin (25 g/t), group III - 1.5% of fumaric acid and flavomycin (25 g/t), IV - 1.5% of fumaric acid, group V - 3% of Cytromix and group VI- 1.5% of Formic-Stabil. It was found that: a) Piglets fed on mixed fodder with the stimulating supplements had higher daily gains of body weight using less fodder per 1 kg of gains compared with animals receiving only the fodder without the supplements; b) The supplements of fumaric acid, formic acid and orthophosphoric acid to fodder designated for piglets aged up to 60 days had a similar influence to other stimulating supplements; c) The best productive effects in piglets aged up to 60 days were observed after administration of supplements in the form of flavonic acid plus fumaric acid; d) Fumaric acid, formic acid, orthophosphoric acid and flavomycin inhibited the development of bacteria and saprophytic fungi in mixed fodder for 6 months.
