Problems solved by technology

[0005] At present, there are many ways to reduce the cholesterol content in eggs. Some trace ingredients can be added to the diet of laying hens, such as: copper, fish oil, allicin, chromium, drugs, etc. These additives can reduce the cholesterol in eggs to a certain extent. However, there are still some problems: such as copper, fish oil, etc., the general reduction rate is about 15%. Although it is very obvious from statistical considerations, the cholesterol content in eggs is still a very high value; some additives have a very good cholesterol-lowering effect. Good, but expensive. For example, HMGR inhibitors can generally reduce the cholesterol content in egg yolks by 40% to 50%. Most of them are used for human medicine, so the cost of feed increases; some additives can reduce the cholesterol content a lot, but the egg production also Reduce a lot, such as high-dose copper (250 mg kg-1) [Zhang Lei et al. Research progress in reducing cholesterol content in eggs. Feed Expo, 2005 (8): 7-9]
Zhang Rude and others disclosed a feed additive for reducing cholesterol content in eggs [Application No. 200710009910.6]. Content, because this kind of feed contains fish oil and other substances, it may make the eggs contain a certain fishy smell, and it increases the cost, so it is not easy to realize industrialization; Su Zhenfang et al. disclose a feed additive [Application No. : 200710115302.3], adding Alisma, seaweed, cassia, perilla, hawthorn, and montmorillonite in the feed, most of these ingredients added belong to Chinese herbal medicine, which may affect the taste of eggs; Cui Yumei et al. disclose a method for reducing egg cholesterol natural compound feed additive and its preparation method [application number: 201110041383.3], the method needs to add the extract of soybean oil foot, the extract of honeysuckle, the extract of coptis, low chitosan and fructooligosaccharide, method and process Complicated, not conducive to operation, high production cost

Embodiment 1

[0023] Add 15% rubber seed kernels of the total amount of feed for laying hens in non-transgenic chicken feed, and make corresponding adjustments to its feed ingredients. The feed composition and the content of each component are:

[0024]

[0025] The above-mentioned chicken feed was fed to laying hens of 130-140 day-old sea blue gray varieties, caged, fed in troughs, free to eat and drink, standing water, and after feeding for 2 weeks, low-cholesterol eggs were obtained. After detection by high-performance liquid chromatography, the cholesterol content in each egg is analyzed to be 180.9 mg. Compared with common eggs, the content of cholesterol in the eggs produced by the invention is reduced by 39.7%.

Embodiment 2

[0027] 20% of the total amount of laying hen feed is added to the non-transgenic laying hen feed with rubber seeds, and the feed is adjusted accordingly. The feed composition and the content of each component are:

[0028]

[0029] The above-mentioned chicken feed was fed to laying hens of 130-140 day-old sea blue gray varieties, caged, fed in troughs, free to eat and drink, standing water, and after feeding for 3 weeks, low-cholesterol eggs were obtained. After detection by high-performance liquid chromatography, the content of cholesterol in each egg is analyzed to be 173.1 mg. Compared with ordinary eggs, the content of cholesterol in the eggs produced by the present invention is reduced by 42.3%.

[0030] Implementation column 3:

[0031] Add 25% rubber seed kernels of the total amount of laying hen feed in the non-transgenic laying hen feed, and make corresponding adjustments to the feed, and the composition and each component content of each male feed are:

Embodiment 4

[0035] Add 20% rubber seed oil cake of laying hen feed total amount and non-transgenic chicken feed, and make corresponding adjustments to its feed composition, feed composition and each component content are:

[0036]

[0037]The above-mentioned chicken feed was fed to laying hens of 130-140 day-old sea blue gray varieties, caged, fed in troughs, free to eat and drink, standing water, and after feeding for 2 weeks, low-cholesterol eggs were obtained. After detection by high-performance liquid chromatography, the content of cholesterol in each egg is analyzed to be 188.1 mg. Compared with ordinary eggs, the content of cholesterol in the eggs produced by the present invention is reduced by 37.3%.

Abstract

The invention relates to a production method for low-cholesterol eggs. The production method comprises the following steps of: (1) adding a rubber seed kernel with the amount being 15-25% of the total weight of feed for laying hens, and rubber seed oil cake with the amount being 20-30% of the total weight of the feed for laying hens into non-gm feed; (2) correspondingly adjusting ingredients of the feed to enable the feed to comprise the ingredients according to the following ratios: 37-46 of corn, 17-24 of soybean meal, 0.57-0.63 of wheat bran, 2.3-2.7 of lard, 15-25 of rubber seed kernel or 20-30 of rubber seed oil cake, 0.33-0.37 of salt, 7-9 of stone powder, 1.7-2.0 of calcium hydrogen phosphate, 0.1-0.11 of lysine, 0.13-0.15 of methionine, and 0.95-1.1 of premix for laying hens; (3) feeding 130-140-day laying hens of Hy-line Variety Brown by using the feed; and (4) obtaining the low-cholesterol eggs after feeding for 2-4 weeks. The content of cholesterol in each low-cholesterol egg produced by the production method is 164.4mg-188.1mg. Compared with common eggs, the cholesterol content in the low-cholesterol eggs produced by the production method is reduced by 39.7%.

Description

technical field [0001] The invention relates to a production method for obtaining low-cholesterol eggs by adding rubber seed kernels or rubber seed oil cakes to laying hen feed. Background technique [0002] Cholesterol, also known as cholesterol, is a derivative of cyclopentane polyhydrophenanthrene. As early as the 18th century, people had discovered cholesterol from gallstones. In 1816, the chemist Bencher named this lipid-like substance cholesterol. Cholesterol is widely present in animals, especially in brain and nerve tissue, and is also high in kidney, spleen, skin, liver and bile. Its solubility is similar to that of fat, insoluble in water, and easily soluble in solvents such as ether and chloroform. Cholesterol is an indispensable and important substance in animal tissue cells. It not only participates in the formation of cell membranes, but also is a raw material for the synthesis of bile acids, vitamin D and steroid hormones. [0003] Cholesterol is necessary ...
