The trial had been carried out during 5 May–30 September 2009, (23 weeks) at the trout farm ICAS Gilau, Cluj County. Two groups were implied: a Control group and one experimental group (Bio-Mos0.2%+SelPlex0.03%+NuPro2%) each consisting of 250 rainbow trout juveniles. The experimental group received 0.2 % Bio-Mos+0.03% SelPlex+2%NuPro. At the end fish reached an average weight of 253.20 g/specimen for experimental group and 241.10 g/specimen for the Control group. The growth rate incresed by 5.23 % at the experimental group comparative with the Control group. The highest value of specific growth rate was recorded at group E, 1.51 g/day, with 5.59 % higher than the specific growth rate of the Controls. The addition of combined fodder additives in group E feed led to an abatement of the feed conversion rate (1.39:1) by 2.12 % smaller comparative with the Control group (1.42:1). The analysis of indices regarding the fish health and survival rate, showed the positive effects of the combined additives. At intestinal level it was noticed an increasement of villi lenght at group E with 10.72 % higher comparative with the Control group. A significant improvement of selenium content of rainbow trout meat was also noticed.

Experiments were performed on 100 lambs, of common race, divided into 4 homogeneous groups of 25 lambs each, which were fed, differentiated for 3 weeks. Lots 1.2 and 3 received a supplement consisting of by-products obtained from the manufacture of biofuels in the area: Feed rations had similar nutritive values for all lambs in the experimental plots. The amount of crude protein in concentrates ratio was 17.40% for group 1, 18.44% for group 2, 17.60% for group 3, and 17.00% for group 4. Bulky feed were given ad libitum for all groups. After the first week of the experiment there was a spectacular evolution of body weight gain. All experimental lots were situated beyond the control group. Body mass growth rate is 3.5 times higher in the group fed with supplement of sunflower meal, 4.16 times higher in that fed with soybean meal supplements and 5.2 times higher in the group fed with additional rape meal. After the second week, the differences are decreasing, as the absolute value of body weight gain.
