Embodiment 1

[0048]

[0049] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The shown flow process prepares compound pellet feed, adds water according to 15wt% of the total weight of each component of powdery compound feed, adds fish paste amount to be 25wt% of each component total weight of powdery feed, adds fish oil amount to each component of powdery feed. 3wt% of the total weight of the components, stir evenly, and use a soft pellet feed machine to make soft pellet feed with uniform color.

[0050] The soft granule compound feed prepared in this example is suitable for feeding juvenile Sturgeon's sturgeon with a body length of 4 cm to 15 cm. Juvenile fish have a high demand for protein, long feeding time, and are prone to illness. In view of the physiological and nutritional characteristics of this stage, the amount of animal protein is increased in the powder formula, the crude protein content of the feed is ≥ 46.0%, and the content o...

Embodiment 2

[0055]

[0056] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The shown flow process prepares compound pellet feed, adds water according to 20wt% of the total weight of each component of powdery compound feed, adds fish paste amount to be 20wt% of each component total weight of powdery feed, adds fish oil amount to each component of powdery feed. 3wt% of the total weight of the components, stir evenly, and use a soft pellet feed machine to make soft pellet feed with uniform color.

[0057] The soft granule compound feed prepared in this example is suitable for feeding the young Sturgeon sturgeon with a body length of 15 cm to 30 cm. Since the nutritional requirements of juvenile fish are higher than those of adult fish, the proportion of protein should be appropriately increased, and the amount of fish oil added should be reduced, so that the crude protein content of feed should be ≥43.0%.

Embodiment 3

[0063]

[0064] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The shown flow process prepares compound pellet feed, adds water according to 30wt% of the total weight of each component of powdery compound feed, adds fish paste amount to be 10wt% of each component total weight of powdery feed, adds fish oil amount to powdery feed each 5wt% of the total weight of the components, stir evenly, and use a soft pellet feed machine to make soft pellet feed with uniform color.

[0065] The soft granule compound feed prepared in this example is suitable for feeding adult Sturgeon's sturgeon with a body length > 30 cm, and the feed crude protein is ≥ 40.0%.

[0066] Formulated feed with existing adult sturgeon (fish meal 38%, α-starch 22%, puffed soybean 16%, fermented soybean 18%, brewer’s yeast 2%, calcium dihydrogen phosphate 1%, mineral 1.5%, sugar beet Alkali 0.5%, choline chloride 0.2%, fish multidimensional 0.3%, salt 0.5%, fish o...

Abstract

The present invention discloses a growth-promoting amur sturgeon soft granule compound feed and a preparation method thereof. The soft granule compound feed is prepared from a powdered feed, water, fish slurry and fish oil. The powdered feed consists of the following components in mass percentages: 25%-35% of fish steak powder, 24%-32% of threonine microbial proteins, 10%-18% of rice bran, 3%-5% of oligopeptide fish soluble powder, 8%-10% of alpha-starch, 2%-5% of beer yeasts, 1%-2% of calcium dihydrogen phosphate, 1%-2% of minerals, 0.3%-0.5% of betaine, 0.2%-0.5% of choline chloride, 0.2%-0.5% of lutein, 0.2%-0.5% of edible salt and 0.1%-0.3% of multi-vitamin for fish. The fish steak powder with similar efficacy is selected to replace fish meal and the oligopeptide proteins, plant proteins and microbial proteins are reasonably added, so that the nutrients of the feed are closer to the nutritional requirements of the amur sturgeons. The feed is higher in attracting property and significantly reduced in costs. The natural antibacterial and immunologically active ingredients are added, so that the feed is free of addition of antioxidants and preservatives, significantly enhances theautoimmune and disease resistances of the amur sturgeons, reduces the incidence of the diseases, and improves the survival rate of breeding.

Description

technical field [0001] The invention relates to an aquatic product compound feed and a preparation method thereof, in particular to a growth-promoting stryckey sturgeon soft granule compound feed and a preparation method thereof, belonging to the field of aquatic product feed. Background technique [0002] Sturgeon is an important freshwater aquaculture species in my country. Sturgeon aquaculture has spread to more than 20 provinces, municipalities and autonomous regions across the country, with an output of up to 90,000 tons. With the continuous expansion of the scale of sturgeon farming, the consumption of sturgeon compound feed is also increasing, and its nutritional needs and feed preparation technology are increasingly concerned. Acipenser schrenckii Brandt (Acipenser schrenckii Brandt) is the most economically valuable fish among the existing sturgeons in China. It has the characteristics of large body, high survival rate, fast growth rate, and delicious meat. However...
