Problems solved by technology

[0004] In addition, both vitamin E and vitamin A are relatively expensive feed ingredients, and the cost must be considered when adding them.
And the amount of vitamin E and vitamin A in the feed has the highest limit, once it exceeds the safe range, it will have a toxic effect on the fish

Embodiment 1

[0012] Two groups of 10cm-long map fish (namely, eye spot cichlid) were taken for feeding experiment comparison.

[0013] After getting 200mg of ferrous fumarate and 200mg of commercial astaxanthin and stirring them evenly, they were added to 1kg of basal feed, and after stirring and mixing, they were fed to the map fish of the test group, while only Contains astaxanthin.

[0014] After feeding for 30 days, the content of commercial astaxanthin in the skin and fin rays of the map fish in the test group was determined. Compared with the map fish of the control group that only added astaxanthin, the astaxanthin in the skin and fin rays of the map fish in the test group The content is 3 times that of the map fish in the control group.

[0015] The color enhancement effect of the map fish fed by the feed prepared by the present invention is compared with that of the map fish only added with astaxanthin. After analysis and detection, the astaxanthin content of the skin and fin ray...

Embodiment 2

[0020] Take 400mg of ferrous fumarate and 200mg of commercial astaxanthin and mix them evenly, then add them to 1kg of basic feed, stir them and feed them with 5cm long map fish. After 20 days of feeding, the obtained map fish The pigmentation of body skin and fin rays is obvious, and the coloring effect is long-lasting and stable. All can reach the effect described in the present invention.

Abstract

The invention provides a feed additive for enhancing the utilization efficiency and coloring effect of colorant of farmed fishes, which is characterized in that synergistic agent blended into 1 kilogram of basal feed comprises the following components by weight: at least 200 milligrams of commercial astaxanthin, and 200 to 400 milligrams of ferrous fumarate. The feed additive can remarkably improve the utilization efficiency and coloring effect of carotenoid colorant on the fishes, has the technical advantages of high technical integration, safe usage, high biological availability and good coloring effect, can improve the utilization efficiency of the carotenoid colorant for the finishes, can promote the immunity of the finishes, balances nutrition, has no chemical medicinal residue, ensures the health of fish bodies, meets the nutritional requirement of the fishes, and has large popularization value.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive that enhances the utilization efficiency and coloring effect of a cultured fish coloring agent. Background technique [0002] The body color of fish determines its market value and market demand. For this reason, many fishes must add carotenoid colorants in the feed during the breeding process to maintain the natural body color. However, the ability of fish to absorb and utilize carotenoids is limited, and most of the colorants cannot be absorbed and utilized by fish, but are excreted with feces, causing economic waste and environmental pollution. [0003] At present, there are some methods to improve the utilization rate of colorants. Because carotenoids are easily oxidized, adding a certain amount of antioxidants, such as vitamin E, to feed can protect carotenoid colorants and improve their utilization. However, the antioxidant capacity of carotenoid colorants is stronger t...
