Embodiment 1

[0028] Example 1 With the raw material components listed in the formula 1 in Table 1, the preparation method of the present invention is used to prepare the extruded pellet feed for Penaeus vannamei, and the specific steps are as follows:

[0029] (1) Weighing the protein source raw materials, fat source raw materials, sugar source raw materials, multivitamins, multimineral salts, food attractants, and water in the parts by weight;

[0030] (2) Grind protein source raw materials, sugar source raw materials, and compound mineral salts for 1-2 times respectively, pass through a 60-mesh sieve to obtain powdery raw materials, mix and stir evenly, and then add fat source raw materials and multivitamins while stirring to prepare Feed base material;

[0031] (3) Input the prepared feed base material into the single-shaft extrusion extruder, turn on the pelletizing motor, and turn the pelletizing frequency converter from "min" to "max", and adjust it to 25-45 , the screw speed is 200...

Embodiment 2

[0035] Example 2 With the raw material components listed in the formula 2 in Table 1, the preparation steps described in Example 1 were used to prepare the extruded pellet feed for Penaeus vannamei; at the same time, the same feed formula was used and implemented according to the The ring die pellet feed preparation method that example 1 adopts makes ring die pellet feed.

[0036] The prepared extruded pellet feed and ring die pellet feed were used to control culture of Penaeus vannamei (divided into extruded pellet feed group and ring die pellet feed group): in a low temperature environment of 13-27°C, 0.40g of South American 80 days for white prawns. After the control breeding, the survival rate SR (%) and the feed coefficient (FCR) of the shrimp in the extruded pellet feed group and the ring die pellet feed group were measured.

[0037] After measurement, in this embodiment, the feed coefficient of the extruded pellet feed group is 1.08, and the survival rate is 79.0%; the...

Embodiment 3

[0038] Example 3 With the raw material components listed in the formula 3 in Table 1, the above-mentioned preparation steps of Example 1 were used to prepare the extruded pellet feed for Penaeus vannamei; at the same time, the same feed formula was used, according to the example 1. The ring die pellet feed preparation method adopted to prepare the ring die pellet feed.

[0039] The prepared extruded pellet feed and ring die pellet feed were used to control culture of Penaeus vannamei (divided into extruded pellet feed group and ring die pellet feed group): in a low temperature environment of 13-27°C, 0.40g of South American 80 days for white prawns. After the control breeding, the survival rate SR (%) and the feed coefficient (FCR) of the shrimp in the extruded pellet feed group and the ring die pellet feed group were measured.

[0040] After measurement, in the present embodiment, the feed coefficient of the extruded pellet feed group is 1.1, and the survival rate is 78.7%; ...

Abstract

The present invention discloses an environmentally protective puffed feed for penaeus vannamei and a preparation method thereof. The environmentally protective puffed feed for the penaeus vannamei isprepared by the following steps: feed raw materials are crushed, the crushed raw materials are mixed to prepare feed base materials, and then water adding, extruding and puffing, granulating and maturing are conducted to prepare a finished product, and the feed consist of the following raw materials in parts by weight: 65-80 parts of protein source raw materials, 2-7 parts of fat source raw materials, 16-20 parts of sugar source raw materials, 0.05-0.2 part of compound vitamin, 0.5-2.0 parts of compound mineral salts and 0-0.2 part of an attractant. According to nutrient requirement characteristics of penaeus vannamei, the animal protein source and plant protein source with high digestibility are selected, and the feed overcomes a problem of an amino acid imbalance of a single protein source, is beneficial to reducing ammonia nitrogen emissions and reduces environmental pollutions, and is simultaneously improved in a formula and conducive to puffing and breeding. A feed coefficient ofthe puffed feed is less than or equal to 1.1, most toxins and anti-nutritional factors are destroyed, the puffed feed is excellent in stability in water, a density of the puffed pellet feed is more than 1.4, a maturing degree is more than 80, and the feed is more comprehensive in nutrients, more palatable than ordinary pellet feeds, and higher in feed efficiency.

Description

technical field [0001] The invention relates to a prawn feed and a preparation method thereof, in particular to an environmentally friendly puffed feed of Penaeus vannamei and a preparation method thereof, belonging to the technical field of aquaculture feed. Background technique [0002] Vannamei Boone (Penaeus vannamei Boone) is native to the waters of the Pacific coast of the Americas, and is mainly distributed from northern Peru to the coast of the Gulf of Mexico, with the most concentrated distribution along the coast of Penaeus vannamei in Ecuador. Penaeus vannamei has the advantages of large individual, fast growth, low nutritional requirements, and strong disease resistance. It has a strong adaptability to changes in water environment factors, has low requirements for feed protein content, has a meat yield of over 65%, and survives out of water. With the advantages of long time, it is one of the three excellent varieties of cultured prawns (Penaeus vannamei, Penaeus ...
