0.1 (A) and 0.3 ppm (B) respectively of selenium in the form of Na2SeO3 was added to the feed mixture that was fed to female New Zealand White rabbits in the final stage of gestation and in lactation period. The addition of selenium to groups A and B had a positive effect on the increasing of body mass of embryos in the last week of gestation (K=36.25 %, A=57.8 %, B=56.4 %) and a significant one on the development of body mass in young rabbits in group A (K=343.6 g, A=436.2 g, B=373.5 g). The content of selenium in mothers' blood decreased in the second week to the lowest level, but in the third week it exceeded the values from the first week (K=1.06/0.74) 1.22, A=0.94/0.93/1.2, B=1.13/0.89/l.l5,microg.g-l DM). In liver of young rabbits the concentration of selenium was significantly higher in group B (K=1.97, A=1.89, B=2.18,microg-1 DM) at age 21 days, while at age 30 days it increased proportionally with the supply of selenium (K=1.95, A=2.20,, B=2.54 ,microg-1 DM). In kidneys the situation was not so clear since the concentration of selenium was higher in comparison with liver, and the highest value was determined at age 30 days in group b (3.22microg-l DM)
