This study examined the effect of the new domestic cell-free brobiotic agents "Biohelp" and "Laktimet" on productiv-ity and resistance of sucking pigs. Administration of these preparations to piglets in early stages of postnatal development in the dose of 1 mg/head increases the liveweight gain by 0.89 kg, or 8.8 %, and 0.99 kg, or 9.8 %, respectively. Over the period of examination, safety of pig population was higher in the group of youngsters under test. With oral administration of "Biohelp" preparation their average daily gain exceeded that of the control by 10.3 %, and with administration of "Laktimet" probiotic – by 11.5 %. Blood se-rum bactericidal activity in animals of experimental groups was higher by 10.5 and 5.4 percentage points respectively, lysozyme ac-tivity – by 15.0 and 8.6 p. p., and systemic phagocytic reactivity of their organism – by 14.9 and 15.6 p. p. as compared to the figures of the control group
