Embodiment 1

[0052] An artificial compound feed for promoting gonad development of broodstock Chinese sturgeon, which is made of the following raw materials in parts by weight:

[0053]

[0054] The inorganic salt premix and the vitamin premix in the feed formula are self-prepared premix, and their specific components and contents are as follows:

[0055] The vitamin premix is ​​prepared from the following raw materials in parts by weight: vitamin B 1 1 serving; Vitamin B 2 3 servings; Vitamin B 6 3 servings; Vitamin B 12 3 servings; Vitamin K 3 2 parts; inositol 79 parts; calcium pantothenate 6 parts; niacinamide 9 parts; folic acid 1 part; biotin 2 parts; vitamin A 22 parts; vitamin D 3 12 parts; 457 parts of vitamin C; 100 parts of vitamin E; 600 parts of choline chloride; 100 parts of astaxanthin; 200 parts of ethoxyquinoline; Vitamin premix.

[0056] Described trace element premix is ​​prepared by the raw material of following weight part: copper sulfate (CuSO 4 ) 3 pa...

Embodiment 2

[0067] The effects of three artificial compound feeds with different fat levels (10%, 14% and 18%) on the gonad development of Chinese sturgeon were studied. The formulas of the three feeds are shown in Table 1.

[0068] An artificial compound feed for promoting gonad development of broodstock Chinese sturgeon, which is made of the following raw materials in parts by weight:

[0069] Table 1 Feed formulations of different fat levels (unit: parts by weight)

[0070]

[0073] The vitamin premix is ​​prepared from the following raw materials in parts by weight: vitamin B 1 1 serving; Vitamin B 2 3 servings; Vitamin B 6 3 servings; Vitamin B 12 3 servings; Vitamin K 3 2 parts; inositol 79 parts; calcium pantothenate 6 parts; niacinamide 9 parts; folic acid 1 part; biotin 2 part...

Embodiment 3

[0094] An application of artificial compound feed in the gonad development of broodstock Chinese sturgeon, the steps are:

[0095] A. Preserve the prepared Chinese sturgeon broodstock feed in a low temperature, dark and dry environment.

[0096] B. Before feeding every day, estimate the daily feeding rate according to the weather conditions. Then calculate the amount of feed that needs to be fed every day, and divide it into two feedings on average.

[0097] C. Stop adding oxygen to the water body when feeding, and reduce the water flow speed to ensure that the feed will not move after sinking to the bottom of the water body, so as to facilitate the feeding of Chinese sturgeon and reduce its time and energy consumption for foraging.

[0098] D. After half an hour of feeding, check the state of the remaining bait at the bottom of the water body, and recycle it in time, so as to accurately correct the feeding rate, reduce feed waste and pollution to the aquaculture water body. ...

Abstract

The invention discloses an artificial compound feed for promoting gonad development of Chinese sturgeon broodstock and its preparation method and application. It is composed of fish meal, soybean meal, flour, chicken meal, fish oil, calcium hydrogen phosphate, vitamins and trace element premix in proportion. The steps are: A. First batching fish meal, soybean meal, chicken powder and flour; B. Superfinely pulverizing the raw materials after batching; C. Putting the pulverized materials into a mixer, mixing calcium dihydrogen phosphate and vitamin premix, Put the trace element premix into the mixer, after mixing, add seawater fish oil into the mixer, and mix; D, prepare the mixed materials, and the modulation process should use a three-layer modulator; E, use extrusion and puffing technology to make Obtain pelleted feed; F, after the feed is dried, spray fish oil through a vacuum sprayer, then wait for the feed pellets to absorb the oil and cool to room temperature; G, measure and pack. The formula is reasonable and the nutrition is comprehensive. It is convenient to use in Chinese sturgeon breeding and provides more balanced and stable nutrition.

Description

technical field [0001] The invention belongs to the technical field of special aquaculture, and more specifically relates to an artificial compound feed for promoting the gonad development of Chinese sturgeon parent fish, and also relates to a preparation method of artificial compound feed for promoting the development of Chinese sturgeon parent Use of artificial compound feeds for gonad development in sturgeon broodstock. Background technique [0002] The Chinese sturgeon lives in large rivers and offshore seas. It is a benthic fish with migratory or semi-migratory characteristics. From May to June in spring and summer, the hibiscus cluster in the mouth of the river, and go up to the upper reaches of the river in autumn. The food of the Chinese sturgeon is mainly some small or slow-moving benthic animals, including shrimps and crabs, fish, molluscs and aquatic insects. [0003] Chinese sturgeon has typical anadromous spawning characteristics. Chinese sturgeon usually liv...
