Effect of replacement of different levels of dietary olive pomace on growth Blood Indices of comman carp fingerling (Cyprinus carpio)

The aim of the present study was to investigate the effects of olive pomace replacement on blood indices and growth of common carp of Cyprinus carpio Common carp with average weight of 19.97 ± 0.05 gr. And average length of 10.55 ± 0.49 centimeters with 6 diets including 0, 3, 6, 9, 12 and 15% olive pomace for 8 weeks in The aquarium was fed. Feeding three times a day at satiation fish was done. After 56 days, the results showed that the 6% level showed the highest growth in terms of weight, length, weight gain, body weight gain, specific growth rate, feed efficiency and liver index But the difference in viscera index was not significant.Blood parameters of common carp showed that in some indices, including RBC, hemoglobin, hematocrit, monocyte and MCHC, no significant differences were observed But in the number of white blood cells, neutrophils, lymphocytes, MCH, MCV, there was a significant difference. The results of this study indicate positive effect of olive pomace replacement to 6% level without negative effect on growth performance and blood factors in common carp ruminant diet. And you can suggest a level of 6% as the appropriate level for replacement.
