Effects of Dietary Cold-Pressed Seed Oils on Growth, Coloration and Blood Parameters in Goldfish
Abstract
This research was conducted to examine the effects of dietary cold-pressed seed oils on growth, coloration and blood parameters in goldfish. A total of one-month-old 240 goldfish were used as the study material. The standard feed enriched with 5 different cold-pressed seed oils (fig, apricot, pomegranate, grape and plum) at a rate of 5% was given to the trial groups, while the control group was fed with the standard feed throughout the experiment. Groups were compared in terms of live weight, total length, specific growth rate (SGR), feed conversion rate (FCR), glucose, cholesterol and triglyceride values. Results showed that dietary seed oils improved the growth performance, feed utilization, coloration and decreased the blood glucose, cholesterol, and triglyceride levels. Seed oil-fed groups gained more weight compared to the control group (P<0.05). Remarkably fig and plum groups yielded higher SGR values (P<0.05). The glucose, cholesterol and triglyceride values in the fig group was found to be the lowest among all groups (P<0.05). Regarding the coloration, darker color shades were found in the pomegranate and fig groups. In conclusion, the use of dietary seed oils makes it possible to grow healthy and fast-growing fish in the desired color.
