preparation example Construction

[0024] The preparation method of the cultured grass carp ramie feed of the embodiment of the present invention, the preparation method of this cultured grass carp ramie feed comprises the following steps:

[0025] Transplant the ramie cutting seedlings on the pond ridge, harvest the green material for the first time after two to three months and directly feed the grass carp, and harvest the green material when the ramie grows to a height of 30cm-100cm;

[0026] Ramie grass powder is made by drying and pulverizing;

[0027] Raw materials are prepared, and the percentages of raw materials in the total weight of raw materials are: 26.46% of wheat bran, 38.23% of rice bran, 31.31% of cottonseed meal, 3.00% of blood meal, and 1.00% of ramie grass powder;

[0028] The raw materials are weighed according to the proportion, and the raw materials to be pulverized are crushed into the particle size of the grass carp feed, and then mixed to obtain the ramie feed.

[0029] As an optimiza...

specific Embodiment approach

[0041] The preparation method of the present invention comprises: harvesting ramie green material, drying and crushing to make ramie grass powder, then designing a formula according to the nutritional requirements of the grass carp feed, and then making a compound feed of the particle size required by the grass carp feed;

[0042] 1. The percentage of each raw material in the total weight of raw materials is: 26.46% of wheat bran, 38.23% of rice bran, 31.31% of cottonseed meal, 3.00% of blood meal, 1.00% of ramie grass powder, weigh each raw material according to these proportions, and crush the raw materials that need to be crushed Become the particle size that meets grass carp feed particle size, mix then, obtain the grass carp feed of this embodiment;

[0043] 2. The percentages of each raw material in the total weight of raw materials are: 47.36% of wheat bran, 10.42% of rice bran, 33.87% of cottonseed meal, 0.36% of rapeseed meal, 3.00% of blood meal, and 5.00% of ramie gr...

Embodiment 1

[0065] In May, the ramie cutting seedlings were transplanted on the pond ridge. After two to three months, the green material was harvested for the first time and fed directly to the grass carp. After that, whenever the ramie grew to a height of 30cm-100cm, it could be fed according to the bait demand of the grass carp. Harvest green material to feed grass carp, and continue to harvest ramie green material in late March or early April of the next year and put it directly into fish ponds to feed grass carp;

Abstract

The invention discloses a preparation method and an application method of a ramie forage used for grass carp breeding. The preparation method comprises following steps: ramie cutting seedlings are transplanted to dry land such as pond ridges, roadsides and corners, and 2 to 3 months later, green fodder obtained for the first time is used for feeding grass carp directly; when the length of ramie reaches 30 to 100cm, green fodder is harvested, and is dried and smashed so as obtain ramie powder; other raw materials, including wheat bran, rice bran, cottonseed meal, rapeseed meal, blood powder, calcium dihydrogen phosphate, feather powder, and maize gluten feed are prepared; the raw materials are weighed according to a ratio, raw materials which are required to be smashed are smashed into particles with a grass carp forage size, and the raw materials are mixed so as to obtain the ramie forage used for grass carp breeding, wherein adding proportion of ramie powder is 1.00 to 90%. According to the preparation method and the application method, healthful aquaculture of grass carp is realized by direct feeding of grass carp with ramie, and adding the raw materials used as mixed feeds. In addition, the preparation method is simple, so that aquaculture cost is reduced, and guarantees of food safety are provided.

Description

technical field [0001] The invention belongs to the technical field of grass carp culture, and in particular relates to a preparation method and a use method of ramie feed for grass carp culture. Background technique [0002] The existing fishery grass species Sudangrass and ryegrass in southern China have been degraded, yields have declined, and pests and diseases have increased, which are no longer suitable for the development of fishery production. Ramie is a plant of the genus Ramie in the family Urticaceae, and is an excellent high-protein feed crop. According to research reports at home and abroad, the nutritional value of the tender stems and leaves of ramie is similar to that of alfalfa, and it is a good protein raw material for plant feed. Ramie is a highly adaptable Crops can also grow well under high-temperature and high-humidity climate conditions. In southern China, compared with planting alfalfa, ramie can obtain higher yields. The protein content of ramie tend...
