ABSTRACT. Experiment was conducted on 15 crossbred pregnant and lactating sows (♂ Landrace × ♀ Large White) and their offspring divided into 3 groups. Sows in group I (control) received basic diet (BD); sows in group III were fed OP supplemented with feed acidifier sodium diformate at the dose of 0.6% during 30 days prior to farrow and during 45 days prior to weaning; in the groups II and III, the piglets were received sodium diformate additive during the period from 10.9 to 35 days of age at a dose of 1.2% and up to weaning at a dose of 0.9% of diet dry matter. Combined use of sodium diformate in the diets of sows and piglets helped to reduce the birth rate of the weak and stillborn piglets, increased conditional milk yield of sows at weaning by 25% (P<0.01), and average daily gain of pigs by 11% (P<0.01) and their viability by 8% (P<0.05) compared with the control group. In group II, the average daily LWG and viability of piglets were higher by 7.6% (P<0.01) and 4,2% respectively compared with the control. The use of sodium diformate in diets of sows and piglets did not have a negative impact on the metabolic processes in the body.
