Problems solved by technology

The current invention simply believes that the same premix formula can be used from larvae to adult fish, but in fact the fish itself has a large difference in nutritional requirements due to different growth stages, which leads to the inability to precisely design different premixes. The fish feed formula in the growth stage causes problems such as low feed utilization rate and serious environmental pollution

Embodiment 1

[0033] The present embodiment provides a kind of tilapia growing mid-stage vitamin premix, which comprises based on the total weight of the premix:

[0034] 21.5% by weight multivitamin, and

[0035] 12% by weight of vitamin precursors, and

[0036] 2.0 wt% organometallic complex, and

[0037] 1 wt% preservative, and

[0038] 5.5 wt% diluent, and

[0039] 58 wt% carrier.

[0040] Tilapia mid-growing vitamin premix contains rich vitamins, vitamin precursors and organometallic compounds, which provide sufficient vitamins and metal elements for tilapia in the mid-growing stage; after granulation, the vitamin premixed The mixture does not dissolve in the stomach of tilapia, and when the stomach is emptied into the intestine, it slowly dissolves and releases under the physiological conditions of the duodenum, avoiding the splitting and degradation of vitamins in the stomach, and greatly increasing the absorption in the intestine The absorption and utilization efficiency of the...

Embodiment 2

[0054] A tilapia mid-growing vitamin premix, which comprises: multivitamins, vitamin precursors, organic metal complexes, protective agents, diluents, and carriers; the tilapia mid-growing vitamin premix contains rich vitamin , vitamin precursors and organometallic compounds, providing sufficient vitamins and metal elements for tilapia in the middle stage of growing; after granulation, the vitamin premix will not dissolve in the stomach of tilapia, and the When it is empty to the intestine, it begins to slowly dissolve and release under the physiological conditions of the duodenum, avoiding the splitting and degradation of vitamins in the stomach, and greatly increasing the absorption and utilization efficiency of vitamin premixes when absorbed in the intestines, significantly improving Utilization synchrony between vitamins in multivitamin premixes and nutrient components in tilapia feed.

[0055] In the mid-stage vitamin premix for tilapia growth, the multivitamins are: vita...

Embodiment 3

[0068] Tilapia grow-out medium vitamin premix containing based on the total weight of the premix:

[0069] 35.5wt% multivitamin, 10wt% vitamin precursor, 1.5wt% organometallic complex, 0.8wt% protective agent, 4.5wt% diluent, 47.7wt% carrier; The mixture is rich in vitamins, vitamin precursors and organic metal complexes, providing sufficient vitamins and metal elements for tilapia in the middle stage of growing; after granulation, the vitamin premix is ​​in the stomach of tilapia No dissolution, when the stomach is emptied to the intestine, it will slowly dissolve and release under the physiological conditions of the duodenum, avoiding the splitting and degradation of vitamins in the stomach, and greatly increasing the absorption of vitamin premixes when absorbed in the intestine The utilization efficiency significantly improves the utilization synchronization between the vitamins in the multivitamin premix and the nutrient components of the tilapia feed.

[0070] In the mid...

Abstract

The invention provides a vitamin premix in the mid-stage of tilapia cultivation, which belongs to the technical field of tilapia cultivation, and comprises, based on the total weight of the premix: 21.5-49.8wt% of multivitamins, 5-12wt% of vitamin precursors, 1.2- 2.0wt% organic metal compound, 0.6-1wt% protective agent, 1.4-5.5wt% diluent, 42-58wt% carrier. The invention also provides a preparation method for the tilapia mid-growing vitamin premix, which includes: mixing, homogenizing and granulating. The beneficial effects are as follows: in the middle stage of tilapia growth, the vitamin premix provides sufficient vitamins and metal elements, the premix dissolves in the intestine, the absorption and utilization efficiency of vitamins is high, and the protective agent in the preparation process is significantly reduced The effect of static electricity between the particles of the premix improves the efficiency of mixing and granulation.

Description

technical field [0001] The invention belongs to the technical field of tilapia cultivation, and in particular relates to a vitamin premix in the middle stage of tilapia cultivation and a preparation method thereof. Background technique [0002] Tilapia, commonly known as: African crucian carp, non-crucian carp, Vietnamese fish, Nanyang crucian carp, etc. Originally refers to the species of Oreochromis mossambicus with Mozambique as the model origin: Mozambique Oreochromis mossambicus, now it is the common name of several species of fish in the genera Cichlidae Oreochromis and Oreochromis mossambicus ; English collectively referred to as Tilapia. Now it is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry, and it is known as one of the main sources of animal protein in the future. Usually live in fresh water, can also live in salt water with different salinity, and can also survive in shallow water of lakes, rivers, and ponds...
