Problems solved by technology

Therefore, the development of low-cholesterol egg technology from the source of diet has attracted much attention, and there are many reports on related technologies, such as functional feed for producing low-cholesterol eggs and its preparation method (application number: ZL201510075400.3), low-cholesterol egg feed and its preparation method (application number: ZL201610447028.9), etc. These technologies all adopt the method of supplementing Chinese herbal medicine in the diet to reduce the cholesterol content of laying hens. Although the effect is good, the feeding cost is also high, because the price of Chinese herbal medicine itself is high. Incompatibility of feed materials and deep processing should also be considered when using it in combination with feed materials. Improper use may cause toxic and side effects on laying hens. Therefore, there are problems and problems such as complex technology, high raw material prices, and unfavorable popularization and application.

specific Embodiment approach 1

[0024] Specific implementation mode 1: comparative analysis of laying hen production performance

specific Embodiment approach 2

[0036] Specific implementation mode 2: comparative analysis of egg quality

[0037] (1) Test method

[0038] The same animal grouping treatment and feeding management methods as in Implementation 1 were adopted. At the end of the 2nd, 4th, 6th, and 8th weekends of the official period, fresh egg samples were collected for 3 consecutive days in the repetition group, and 30 eggs were randomly selected from each treatment group to measure the whole egg weight, egg yolk weight, egg transverse diameter, and egg weight. Egg quality indicators such as longitudinal diameter and egg shape index.

[0039] (2) Results and analysis

[0040] From the second week of the official period, the egg quality was measured every two weeks, and the analysis results are shown in Table 3. The analysis showed that the two different feeds had no significant effect on the egg long diameter, egg short diameter, average egg weight, and relative egg yolk weight of eggs, but the egg shape index of the nett...

specific Embodiment approach 3

[0044] Specific implementation mode 3: comparative analysis of egg cholesterol content

[0045] (1) Test method

[0046] Select 120 healthy, 28-week-old Hailan brown commercial laying hens with similar egg production rates, and randomly divide them into 3 treatment groups, each treatment group is divided into 5 repetition groups, each repetition group has 8 chickens, and 3 treatments The groups were: basal feed group (control group), basal feed + alfalfa powder group, basal feed + nettle grass powder group. The amount of alfalfa powder and nettle grass powder added is 10%-15%. The alfalfa powder was purchased from a forage enterprise, and the nettle grass powder was obtained by drying and crushing the twigs and leaves of nettle stinging nettles naturally. Conditions such as diet composition, feeding amount, feeding management, feeding cycle of 3 groups of laying hens are all identical with embodiment 1. At the end of the 4th and the 8th week of the official period, 3 chicke...

Abstract

The invention discloses a method for raising functional eggs with low cholesterol, high calcium and high vitamin A, and belongs to the technical field of production of functional animal products. The problems of high feed raw material price, complex processing and utilization operation and limited popularization and application acceptability in the existing technology for producing low-cholesterol eggs from a feed source are solved. Nettle widely distributed in nature is naturally dried in the sun and ground into grass meal, the grass meal is directly mixed with basic chicken feed, the cholesterol content of eggs can be effectively reduced after the chicken is fed for 4 weeks, the cholesterol content of the eggs is reduced by 13.64% compared with a control group and 8.87% compared with an alfalfa meal group after the chicken is fed for 8 weeks, meanwhile, the content of vitamin A and mineral substances including calcium, iron, zinc and manganese is increased, the calcium content is increased by 2.03 times compared with that of the control group and increased by 1.20 times compared with that of the alfalfa meal group, and the iron content reaches 35 mg/kg and is higher than the limited human body absorption level.

Description

technical field [0001] The invention relates to a method for raising functional eggs with low cholesterol, high calcium and high vitamin A, and belongs to the technical field of production of functional livestock products. Background technique [0002] Eggs are rich in nutrients and contain almost all the nutrients needed by the human body. They are indispensable livestock products for people's three meals. At the same time, eggs are also a high-cholesterol food. Eating more will lead to excessive cholesterol intake and lead to the risk of cardiovascular and cerebrovascular diseases, especially for middle-aged and elderly people. Cholesterol is closely related to atherosclerosis, so the American Heart and Cerebrovascular Association recommends that the daily intake of adults should be less than 300mg, while commercially available ordinary eggs contain about 400-600mg of cholesterol per 100g, and each egg contains about 250-250mg of cholesterol. 350mg. Therefore, the develo...
