Problems solved by technology

In recent years, large-scale grass carp (5-10 catties) is more and more favored by farmers due to its large individual size, high and stable price, and low mortality rate. However, its growth is slow and the bait coefficient is high. Feeding a large amount of large-scale grass carp will cause waste of feed, and the nutrients in the feed that are not absorbed by the fish will be discharged into the water body with the feces, resulting in poor water quality, deterioration of the water body, and pollution of the environment
In actual production, it is often used to reduce the feeding of compound feed, or not to feed it, but to increase the amount of green material and bran fed, so as to keep grass carp with a basic sense of satiety and save costs. However, due to the unstable source of these raw materials and unbalanced nutrition, it is extremely unfavorable to the growth of grass carp. At the same time, reducing the feeding of compound materials will reduce the feed that the silver carp and bighead carp in the pond can eat, affecting their growth and final output.

Embodiment 1

[0024] Prepare materials according to the following mass percentages:

[0025] Fish meal 6%, soybean meal 11%, cotton meal 13%, rapeseed meal 22%, rice bran 17%, bran 18%, rapeseed 3%, soybean 6%, salt 0.3%, calcium hydrogen phosphate 1.5%, bentonite 1.5%, Premix 0.8%.

[0026] Preparation method: crush all the solid raw materials in the above raw materials into fine powder, pass through a 60-mesh sieve, then mix in order, and stir evenly; carry out high-temperature granulation at 95°C, and the diameter of the granulation ring die is 3.5mm, which conforms to KGB According to the requirements of / T 1675, it is made into pellet feed for adult fish; then 5% of the pellet feed is crushed into a fine powder of about 1.0 mm, and added to the pellet feed in proportion.

Embodiment 2

[0028] Prepare materials according to the following mass percentages:

[0029] Fish meal 4%, soybean meal 12%, cotton meal 14%, rapeseed meal 21%, rice bran 18%, bran 18%, rapeseed 5%, soybean 4%, salt 0.3%, calcium hydrogen phosphate 1.5%, bentonite 1%, Premix 1%. Preparation method is the same as example one.

Abstract

The invention discloses a feed suitable for mixed raising mode of grass craps, silver carps and bighead carps on a large standard, which comprises the following components in percentage by weight: 3-8% of fish meal, 10-15% of bean meal, 10-15% of cotton meal, 17-22% of vegetable meal, 15-22% of rice bran, 15-20% of bran, 3-8% of rape seed, 3-8% of soybean, 0.3-0.8% of salt, 1-2% of calcium hydrophosphate, 1-2% of bentonite, and 0.8-1.5% of premix compound. In addition, the invention also provides a production method for the feed suitable for the mixed raising mode of grass craps, silver carpsand bighead carps on a large standard. Compared with the prior art, the feed suitable for the mixed raising mode of grass craps, silver carps and bighead carps on a large standard and the production method, which are provided by the invention, have the advantages that the adopted raw materials are low in cost, are easy to identify and have small possibility of counterfeit, thus the stability of the quality of the feed can be guaranteed to the maximum degree, grass carps on a large standard can be cultured, and the output of filter-feeding fishes is increased so as to improve the comprehensivebenefits of pond breeding.

Description

technical field [0001] The invention relates to the field of aquaculture feed, and specifically refers to a feed and a production method suitable for the polyculture mode of large-scale grass carp, silver carp and bighead carp. Background technique [0002] Grass carp (Ctenopharyngodon idellus) belongs to the genus Grass carp of Cyprinidae Cyprinidae and is one of the four major fishes in freshwater farming in China. White carp, etc., English name: Grass carp. It inhabits rivers and lakes in plain areas, and generally prefers to live in the middle and lower layers of water and areas with many aquatic plants near the shore. Its body is subcircular in length, flat at the rear, blue-yellow in color, broad and flat, with a slightly dotted snout, long mouth and no beards. Pharyngeal comb-shaped, two rows of sharp teeth, good at biting grass stems, it is a typical herbivorous fish. Grass carp has the characteristics of fast growth, high yield, fresh and tender meat, and rich nu...
