Effect of varied amounts of ginger oil in the feed on common carp growth metrics L. Cyprinus Carpio

Abstract

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 ginger oil on the diets of common carp Cyprinus carpio L., the experiment lasted for 82 days, including the 10-day acclimatization period. 80 common carp fish with an average weight of 77±0.56 g was used. It was randomly distributed to 5 treatments with 3 replicates (5 fish each replicate). The fish were fed on experimental diets, divided into four equal treatments in terms of protein percentages and different levels of ginger oil, and the percentage of seeds added to the treatments was 0, 0.25, 0.50 and 1.00%, respectively. The fish were fed on the experimental diets at 5% of the live weight, divided into 4 meals daily. The results indicated a significant superiority of all ginger oil treatments in the growth parameters of carp fish, represented by body weight, weight gain, and daily, specific and relative growth rate. Adding 0.50% ginger oil gave the best results, compared with all ginger oil treatments in growth parameters of carp fish. Keywords: ginger oil, growth parameters, common carp Cyprinus Carpio L.
