Problems solved by technology

Although it has broken through the problem of artificial breeding of golden pomfret, the feeding of golden pomfret fry still relies on imported or chilled miscellaneous fish paste and eel meal, which seriously pollutes the water quality and causes many fish diseases in the later stage of breeding
At present, there is no open pellet feed for golden pomfret fry in the domestic market

Embodiment 1

[0015] Crush 500 kg of imported fish meal, 160 kg of soybean meal, 60 kg of shrimp meal, 45 kg of squid liver paste, 220 kg of flour, and 15 kg of minerals (phosphorus or zinc) into 80 meshes and enter the puffing machine for pretreatment. After puffing pretreatment, it is superfinely pulverized to 200 mesh, and the pulverized thing is the core material.

[0016] Then 15 kg of spirulina, 20 kg of fish oil, 1.5 kg of vitamins (vitamin A or vitamin B), 45 kg of gelatin, and 418.5 kg of water were mixed and homogenized by colloid milling to a fineness of 200 mesh, and used as wall material coating; Microcapsule bait was made by spray drying method. When preparing microcapsule bait, the ratio of wall material (cured material) to core material is 1:100. The most commonly used method for making microencapsulated bait is the spray drying method. The first air inlet temperature is 81°C for 10-15 minutes, the second air inlet temperature is 200°C for 8-10 minutes, and the outlet air ...

Embodiment 2

[0018] 55 kg of imported fish meal, 13 kg of soybean meal, 5 kg of shrimp powder, 5 kg of squid liver paste,

[0019] 21 kg of flour and 1 kg of minerals (iron or copper or manganese) are pulverized to 80 mesh and enter the puffing machine for puffing pretreatment. After puffing pretreatment, it is superfinely pulverized to 200 mesh, and the pulverized thing is the core material. Then mix 1 kg of spirulina, 2 kg of fish oil, 0.1 kg of vitamins (vitamin C), 4 kg of gelatin, and 42.9 kg of water, and pass through a colloid mill with a fineness of 200 mesh to make the wall material coating; use spray drying The method is made into microcapsule bait. When preparing microcapsule bait, the ratio of wall material (cured material) to core material is 10:100. The most commonly used method for making microencapsulated bait is the spray drying method. The first air inlet temperature is 81°C for 10-15 minutes, the second air inlet temperature is 200°C for 8-10 minutes, and the outlet ai...

Embodiment 3

[0021] Crush 50 kg of imported fish meal, 14 kg of soybean meal, 6 kg of shrimp meal, 5.5 kg of squid liver paste, 23 kg of flour, and 1.5 kg of minerals (selenium or cobalt) to 80 mesh and enter the puffing machine for pretreatment. After puffing pretreatment, it is superfinely pulverized to 200 mesh, and the pulverized thing is the core material. Then mix 1.5 kg of spirulina, 1.5 kg of fish oil, 0.1 kg of vitamin (vitamin D), 4 kg of gelatin, and 42.9 kg of water, and pass through a colloid mill with a fineness of 200 mesh to make the wall material coating; use spray drying The method is made into microcapsule bait. When preparing microcapsule bait, the ratio of wall material (cured product) to core material is 5:100.100. The most commonly used method for making microencapsulated bait is the spray drying method. The first air inlet temperature is 81°C for 10-15 minutes, the second air inlet temperature is 200°C for 8-10 minutes, and the outlet air temperature is 70°C for 20...

Abstract

The invention discloses a method for producing a microencapsulated starter diet for Trachinotus ovatus fries. The method comprises the following steps of: metering imported fish meal, soybean meal, shrimp meal, cuttlefish liver paste, flour and mineral substances, crushing, mixing uniformly, and feeding the mixture into an expanding machine and performing expansion pretreatment; performing ultrafine crushing after expansion pretreatment, wherein a crushed object is a core material; mixing spirulina, fish oil and various vitamins, dissolving in aqueous solution of gelatin, and homogenizing by using a colloid mill to obtain a product serving as a wall material coating; and preparing a microencapsulated bait from the wall material and the core material in a ratio of (1-10):100 by a spray drying method, screening the prepared microencapsulated bait according to particle sizes required by various growth periods of Trachinotus ovatus, packaging and warehousing. The method has the advantages that: through the experiment, the microencapsulated bait prepared from main raw materials which are subjected to expansion pretreatment and enveloping has good feeding attraction, is easy to digest and absorb, can effectively keep the stability and suspension property of a bait in water, and is favorable for the intake of the Trachinotus ovatus fries, so that the broad application prospect of the starter diet for the Trachinotus ovatus fries in marine fish feeds is opened up.

Description

Technical field: [0001] The invention relates to a production method of a microcapsule feed for golden pomfret fry, in particular a production method for a microcapsule feed of golden pomfret fry with a size of ≤1.8 cm, belonging to the technical field of feed and feed additives. Background technique: [0002] Since 2000, more than 80% of the coastal tidal farming area has been dominated by the culture of Penaeus vannamei, because Penaeus vannamei is indeed a very good species, and it has also driven the people to become rich and lift themselves out of poverty, and tens of millions of people have benefited from it. However, in recent years, due to the rapid expansion of personnel entering the vannamei industry, the annual output of vannamei has increased by almost 30%. It is difficult to digest the oversupply in the domestic market, and the export is increasingly threatened. In 2004 and 2007, the entire industry suffered a catastrophic blow, and none of the links such as exp...
