Embodiment 1
[0020] Quail feed enriched in nutrition and rich in natural astaxanthin, comprising the following components in mass percentage:
[0021] Natural astaxanthin 5%, poultry feed 95%;
[0022] Among them, the poultry feed consists of the following components in mass percentage: 63% corn, 25% soybean meal, and 7% shell powder;
[0023] Natural astaxanthin has a left-handed structure, including all-trans, 9-cis and 13-cis isomers, and the all-trans isomer is the main one, accounting for 3 / 4 of the natural astaxanthin components; natural astaxanthin The element is extracted from Haematococcus pluvialis.
[0024] The natural astaxanthin extracted from Haematococcus pluvialis accounts for 0.1-6% of the weight of Haematococcus pluvialis, and its ratio of all-trans: 9 cis: 13 cis is (82-85%): (7 ~10%): (5~10%).
[0025] Utilize above-mentioned quail feed, after feeding quail for 3-5 days, collect astaxanthin-rich quail eggs produced by quail, the yolk color of the quail eggs is obviou...
Embodiment 2
[0027] Quail feed enriched in nutrition and rich in natural astaxanthin, comprising the following components in mass percentage:
[0028] Natural astaxanthin 1%, poultry feed 99%;
[0029] Among them, natural astaxanthin has a left-handed structure, including all-trans, 9-cis and 13-cis isomers, and the all-trans isomer is the main one, accounting for 3 / 4 of the natural astaxanthin components; Astaxanthin is extracted from fungi or fish, extracted from each raw material separately and mixed for use.
[0030] Poultry feed is with embodiment 1, also adds following component:
[0031]
[0032] Feed the quails in the egg-laying period with the above-mentioned quail feed, and obtain quail eggs basically similar to Example 1 after 3 days, that is, the yolk color of the quail eggs is obviously deepened, which is rich in natural astaxanthin, and also increases with the extension of feeding time. , its yolk color gradually deepens until it becomes dark red.
Embodiment 3
[0034] Quail feed enriched in nutrition and rich in natural astaxanthin, comprising the following components in mass percentage:
[0035] Natural astaxanthin 10%, poultry feed 90%;
[0036] Among them, natural astaxanthin has a left-handed structure, including all-trans, 9-cis and 13-cis isomers, and the all-trans isomer is the main one, accounting for 3 / 4 of the natural astaxanthin components; Astaxanthin is extracted from fish, shrimp, crab, and plants, and is extracted from each raw material separately and mixed for use.
[0037] When the quails in the laying period were fed with the above-mentioned quail feed, the egg yolk color began to deepen on the first day, which was similar to the standard of free-range quail eggs; after 2 days, the egg yolk color deepened to orange; and as the feeding time prolongs, the egg yolk color Gradually deepening, the yolk color of the quail eggs obtained after 3 days is stable and dark red.
