| Popis: | This current study aimed to study the effect of adding blue-green algae (Spirulina), symbiotic (poultry star®me) at a ratio of 1 to 2% and colistin antibiotic to the control diet of common carp fish reared in glass aquariums for 56 days terms of three replicates for each treatment. The growth results showed that the fish fed on the third diet was significantly superior to the fish fed on the other experimental diets in the rate of total and daily weight gain, feed conversion ratio, feeding efficiency ratio and protein efficiency ratio criteria over all other experimental diets except for the second diet, 1% spirulina. The fish fed on the second diet significantly outperformed in the precipitated protein criterion and the protein productive value of all the experimental diets under study. The value of crude protein in the edible portion increased significantly when fish were fed on spirulina, symbiotic and antibiotic diets, compared to the control diet, while the percentage of fats in the fish fed on diets containing the food additives under test decreased significantly compared to the control diet. No significant differences were recorded in the percentage of ash. It is evident from what was mentioned above that the best results of the studied criteria were when adding spirulina at had positive effects on growth criteria and food utilization. |
