Effect different levels of safflower seed powder to the diets on some histological traits to the diets of common carp Cyprinus carpio L.

Abstract

The study was conducted at special cages in mud pond, Agricultural Research and Experiment Station, Animal Production Department, Agriculture College, Al-Muthanna University, to study the partial replacement of safflower seed powder by levels of 0, 5, 10 and 15%, in the diets, instead barley and yellow corn, and the effects on the growth and blood parameters of common carp fish. The experiment was designed as four treatments with four replicates for each treatment (five fish/ replicate). The study included the effect of seeds on the histological parameters of carp fish, where the results showed histological examination of the organs of the liver, kidneys and gills, treatments of safflower seed powder fed at 5%, 10%, and 15% improved compared to T1 treatment. We conclude from this study the possibility of adding raw safflower seed powder by 10% to the diets of common carp fish Cyprinus carpio L.
