تغذية أسماك الكارب الشائع على علائق تحتوي على نسب مختلفة من الزنجبيل (Zingbar officinale) وتأثيره على صفات الدمية والمعايير الكيموحيوية

Abstract

Common carp (Cyprinus carpio L.) were manually fed a diet supplemented with ginger powder (Zingiber officinalis) at levels (0, 6, 8, and 10) % to observe the effect of ginger powder on blood and biochemical parameters. The research was conducted in the fish laboratory of the Faculty of Animal Production /College of Agriculture and Forestry/University of Mosul. In this study 84 fish were used and distributed over 12 glass tanks with an average weight of 28 ± 1gm. The fish were fed 3 times a day at a rate of 3% of body weight for a period of 56 days. At the end of the experiment, there were significant differences (P<0.05) in the hemoglobin standard in the treatments to which ginger was added compared to the control treatment. PCV values also increased in fish fed on the added diets. Also, albumin values decreased in treatments to which ginger was added compared to the control treatment, and globulin values decreased in treatment 2 (6% ginger). There were also no significant differences in the total protein standard between the control treatment and the treatments to which ginger was added, except for the treatment which had an 8% level of ginger. The level of glucose also decreased significantly in blood of fish fed on ginger compared to the control treatment. while the values of cholesterol and triglycerides varied for the ginger treatments compared to the control treatment. Also the values of Aspartate Transaminase enzyme (AST) decreased in the treatments to which ginger was added compared to the fish fed on the control diet and Alanine Transaminase enzyme (ALT) values also decreased in all treatments that had ginger added to it compared to the control except for the fourth treatment (10% ginger), which was higher than the rest of the treatments. Feeding fish diets containing ginger lowered hemoglobin in the blood.
