Embodiment 1

[0026] Add 10% of the total amount of laying hen feed to the non-transgenic chicken feed, and adjust the feed ingredients accordingly. Add 5 international units of vitamin E per kilogram of feed. The feed composition and the content of each component are: :

[0027]

[0028] Feed the above-mentioned chicken feed to 130-140-day-old laying hens of the sea blue gray variety, adopt cage feeding, feed in a trough, eat freely, keep water, and after feeding for 2 weeks, eggs rich in omega-3 series fatty acids are obtained. After analysis by GC-MS, the contents of omega-3 series fatty acids in each egg (edible part) are DHA: 116.8mg, EPA: 87.9mg, 102.1mg, the total content is 306.8mg.

Embodiment 2

[0030] Element content(%) corn 42.89 soybean meal 27.09 wheat bran 0.59 lard 2.66 rubber seeds 15．00 salt 0.35 stone powder 8.38 Calcium hydrogen phosphate 1.80 Lysine 0.10 Methionine 0.14 Layer Premix 1.00

[0031] Feed the above-mentioned chicken feed to 130-140-day-old laying hens of the sea blue gray variety, adopt cage feeding, feed in a trough, eat freely, keep water, and after feeding for 3 weeks, eggs rich in omega-3 series fatty acids are obtained. After analysis by GC-MS, the content of omega-3 series fatty acids in each egg (edible part) is DHA: 149.4mg, EPA: 101.4mg, 107.2, the total content is 358mg.

Embodiment 3

[0033] Element content(%) corn 42.89 soybean meal 22.25 wheat bran 0.59 lard 2.5 rubber seeds 20.00 salt 0.35 stone powder 8.38 Calcium hydrogen phosphate 1.80 Lysine 0.10 Methionine 0.14 Layer Premix 1.00

[0034] The above-mentioned chicken feed was fed to layer hens aged 130-140 days, and they were raised in cages, fed in troughs, free to eat and drink, and kept water. After feeding for 4 weeks, eggs rich in omega-3 series fatty acids were obtained. After analysis by GC-MS, the contents of omega-3 series fatty acids in each egg (edible part) are: DHA: 225.4mg, EPA: 156.5mg, 110.9mg, the total content is 492.8mg.

Abstract

The invention relates to a preparation method for eggs rich in omega-3 polyunsaturated fatty acids. The preparation method comprises the following steps of: (1) adding screened rubber seed kernel or rubber seed oil cake into non-gm feed for laying hens, with the additive amount of the rubber seed kernel being 10-20% of the total weight of the feed for laying hens, and the additive amount of the rubber seed oil cake being 15-25% of the total weight of the feed for laying hens; (2) adjusting ingredients of the feed to enable the feed to comprise the following ingredients: 42.89 of corn, 17-32 of soybean meal, 0.59 of wheat bran, 2-3 of lard, 10-20 of rubber seed kernel or 15-25 of rubber seed oil cake, 0.35 of salt, 8.38 of stone powder, 1.8 of calcium hydrogen phosphate, 0.1 of lysine, 0.14 of methionine, 1 of premix for laying hens, and 5 international units of vitamin E per kg of feed; (3) feeding 130-140-day laying hens by using the feed for laying eggs rich in omega-3 polyunsaturated fatty acids after feeding for 2-4 weeks. The preparation method is low in cost, stable in content of the omega-3 polyunsaturated fatty acids, and safe without peculiar smell, and effectively and sufficiently utilizes rubber seed resources.

Description

technical field [0001] The invention relates to an egg rich in omega-3 series polyunsaturated fatty acids and a preparation method thereof. Background technique [0002] ω-3 series polyunsaturated fatty acids (ω-3PUFAs), which are long-chain unsaturated fatty acids (with 18-22 carbon atoms), mainly include (LNA), eicosapentaenoic acid (EPA, containing 5 unsaturated double bonds) and docosahexaenoic acid (DHA, containing 6 unsaturated double bonds). The process of omega-3 fatty acid metabolism in the human body is: the body converts the ingested α-linolenic acid (LNA) into eicosapentaenoic acid (EPA), and the body converts EPA into docosahexaenoic acid (DHA ). Substances with various biological activity adjustments are formed through the fatty acid oxidation metabolism process and absorbed by the human body. [0003] α-linolenic acid, EPA, and DHA play different roles in the body. Compete with the omega-6 series of polyunsaturated fatty acids for the same enzyme in huma...
