Impact of varying amounts of Moringa oleifera seed powder in the diet on a few aspects of common carp growth L. Cyprinus carpio

The current study was conducted in experimental cages in a mud pond, First Agricultural Research and Experiment Station, Agriculture College, Al-Muthanna University, to determine the effect of different levels of Moringa oleifera seed powder on the diets of common carp. A total of 75 common carp fish with an average weight of 65.08±0.42 g were used; it was randomly distributed to 5 treatments with three replicates (5 fish for each replicate). The fish that were fed on experimental diets was divided into five equal therapies in terms of protein percentages, different in the proportions of adding Moringa seed powder; the rate of seeds added to the treatments was 0, 0.5, 1, 1.5 and 2%, respectively, the fish were fed on the experimental diets at 5% of the live weight, divided into four meals a day. The results showed a significant superiority of T2 and T3 treatments compared with other therapies on growth parameters (final weight, weight gain, daily growth rate, specific and relative), and give the best feed conversion ratio, the highest food conversion and protein efficiency ratio. Indicates that adding Moringa seed powder to diets at rates of 0.5 and 1% led to fish growth promotion and increased utilization of feed intake.
