Abstract: Four hundred carp fries (Cyprinus carpio L. 1758) with average initial weight of 1.11±0.05 g and total average length of 4.04±0.04 cm, was fed for a period of 90 days with the addition of commercial feed Mannanoligosaccharide (MOS) and vitamin B12. The carps were divided into four different groups and fed through different feeds (Control; group A with MOS, group B with vitamin B12, group C with a the combination of MOS + vitamin B12). The effects of feeding through MOS and vitamin B12 in different proportions on the parameters such as growth in view of live weight and total length, survival rate, feed conversion, condition factor and protein efficacy for the carp fries was studied. The best growth in view of live weight was maintained through MOS and vitamin B12 combination in group C (4.51±0.13 g), while the best growth in terms of length was obtained through MOS in group A (6.68±0.08 cm). As a consequence, the growth parameters of the carp fries fed through commercial feeds with the addition of MOS and vitamin B12 in different doses under empirical conditions shown affirmative effects on the survival rate, feed assessment, condition factor and protein efficacy.
