Embodiment 1

[0007] Embodiment 1: Alfalfa root is pulverized and then extracted. The total amount of digestible nutrients in the extract accounts for 28-60% of dry weight, reducing sugar 0.8-5.2%, total sugar content 3.2-7.6%, starch 1.3-5.8%, non- Structural total sugar 5.0-8.8%, crude protein 3.8-13.5%, ether crude extract 0.6-6.5%, crude fiber 30-67%, ash 4.5-13%, phosphorus 0.08-0.62%, potassium 0.28-2.1 %, calcium 0.6-2.7%, magnesium 0.37-0.43%, aluminum 42-260PPM, barium 32-88PPM, iron 55-240PPM, strontium 8-120PPM, boron 13-105PPM, copper 3-22PPM, zinc 21-110PPM, manganese 8-420PPM. Ether crude extract contains phospholipids, sterols, alfalfa saponins, carotene, pseudoestrolactone.

Embodiment 2

[0008] Example 2: In Example 1, the alfalfa root was pulverized and soaked in purified water, and the concentrated solution after filtration contained alfalfa saponins formed from pentacyclic saponin and various sugars. The content of alfalfa saponins in alfalfa root is 10 times that of alfalfa leaves, and the composition is different.

Embodiment 3

[0009] Example 3: In Example 1, the alfalfa root was pulverized and fumigated with pure water vapor, and the dry matter was added into a solvent for extraction. Pseudoestrolactone is a kind of phytoestrogen. When it is used to raise sheep, it can change the luteinizing hormone level of sheep and cause infertility. Adults who consume more than 1mg of pseudoestrolactone per day can cause pathological side effects. Due to the low boiling point of pseudoestrolactone, it will basically volatilize after heating.

Abstract

The invention relates to a culture method of a new golden-yellow strain of Chlamys nobilis rich in natural carotenoid, which comprises the steps of: seed selection, single individual induced spawning,family establishment by monogam insemination, offspring seed culture, intermediate breeding and cultivating, color purification check, new strain multiplication and continuous selective breeding andthe like; and the new golden-yellow strain of the Chlamys nobilis rich in natural carotenoid can be cultured by two-generation directional selective breeding. The new strain has stable character, notonly has golden-yellow shell, adductor muscle and pallium, but also is rich in the natural carotenoid; averagely, 98% of individuals have golden-yellow shells, 96% of individuals have golden-yellow adductor muscle, 99% of individuals have golden-yellow pallium, and the total content of the carotenoid is 4.2-13.8 times of that of groups not subjected to the selective breeding. The invention culturea new strain of shellfish from the angles of the sensed color and the nutrition.

Description

technical field [0001] The invention relates to a selective breeding and genetic improvement technology in the research of shellfish genetics and breeding, in particular to a method for cultivating a new strain of Chlamys farreri. technical background [0002] Carotenoids, also known as lipochromes, belong to terpenoids. Usually refers to the 40-carbon hydrocarbons, that is, carotene, and the oxidized derivatives of carotene, that is, lutein. Carotenoids are the general term for these two types of pigments. Carotenoids are mainly synthesized by higher plants, algae and microorganisms, and exist in nature in the form of yellow, orange-red or red pigments. So far, more than 650 kinds of carotenoids have been found (Matsuno, 2001; Ren Yongxia et al., 2003). Animals cannot synthesize carotenoids by themselves, but animals can store them in their bodies by ingesting natural carotenoids from the outside world, so carotenoids widely exist in animals, plants and microorganisms....
