The aim of the research was to evaluate the influence of probiotic BioPlus 2B on the weight loss of sows during lactation, and on the insemination frequency of sows. In total 126 sows from two weeks before farrowing to weaning from commercial pig farm SIA “Korkalns” were used for the research. The sows were split into two groups: the trial group was given probiotic BioPlus 2B supplemented feed, and the control group was given non-supplemented feed. The trial was performed in three replications. The results showed that the live weight loss of sows was 42.1 ± 1.78 kg (16%) in the control group, but in the trial (probiotic) group it was 21.3 ± 1.42 kg (7.8%). The difference of live weight loss of sows was significant (p is less than 0.05). The higher feed intake (6.6 kg per day) of the sows in the probiotic group resulted in smaller live weight loss. The feed intake of the control group sows was 5.6 kg per day. Although insemination of sows in the control and experimental groups followed on the 4th – 5th day after weaning piglets, comparatively more sows needed re-insemination in the control group – 22 sows or 36% of the total number of sows, but in the trial group 13 or 20.0% were re-inseminated.
