Problems solved by technology

The traits are not suitable for feeding all aquaculture objects, and cannot completely replace natural fresh bait. Therefore, some fish and snails are still fed with natural fresh and live small miscellaneous fish, such as large yellow croaker, oriental snails, etc.
However, natural fresh and live small miscellaneous fish resources are increasingly scarce, and the supply is extremely unstable. There are many constraints, such as fishing season, climate, fishing moratorium, etc., and it is impossible to keep fresh for a long time at room temperature.
[0004] In order to overcome the disadvantages that artificial hard granular feed, extruded feed and powder feed are not suitable for feeding some fish and snails, and the supply of natural fresh and live small miscellaneous fish is unstable and cannot be kept fresh for a long time at room temperature, the invention provides a An artificial soft granule aquatic feed, the soft granule feed is easy to use, not only can completely replace the natural fresh and live small miscellaneous fish when raising large yellow croakers, oriental snails, etc. Store for more than 30 days without deterioration

Embodiment 1

[0019] Embodiment 1 (fish feed)

[0020] Weigh the following raw materials (in Kg): fish meal 56.0, fermented soybean meal 5.0, beer yeast powder 10.0, seaweed powder 1.0, potassium dihydrogen phosphate 1.5, choline chloride 0.3, lysine 0.3, methionine 0.1, arginine 0.1 .

[0021] The above raw materials are pulverized into 95% powders passing through a 100-mesh sieve, placed in a 250L kneader, and then add alginate (thickener) 6.0, hydrolyzed fish paste 13.0, fish oil 2.0 and biological preservation liquid 4.0, in the kneader Knead for 20 to 30 minutes, and extrude the kneaded feed material with a 120-type screw to make short cylindrical soft granules.

Embodiment 2

[0022] Embodiment 2 (Dongfeng snail feed)

[0023] Weigh the following raw materials (in Kg): fish meal 60.0, fermented soybean meal 6.5, beer yeast powder 5.0, potassium dihydrogen phosphate 2.5, choline chloride 0.3, lysine 0.3. Grind the above raw materials into 95% powders passing through a 100 mesh sieve, put them in a 250L kneader, add alginate (thickener) 6.3, hydrolyzed fish paste 13.0, fish oil 2.0, biological preservation solution 4.0 and capsanthin 0.1, knead in a kneader for 20 to 30 minutes, and use a 120-type screw extruder to knead the kneaded feed material into short cylindrical red soft granules.

Embodiment 3

[0024] Embodiment 3 (comparative test)

[0025] In the experiment, 50 adult giant salamanders with a body length of 30 cm were used, and they were cultured in a large cement pond of 5 m × 5 m × 2 m in flowing water. The experiment was divided into two groups. The group was fed with soft pelleted feed for adult giant salamander processed in the above examples, and the culture period was 60 days, and the body weight was weighed after the experiment. The soft pellet feed is resistant to water soaking for 8 hours without deformation and collapse during feeding, and the palatability of the giant salamander is good. The weight gain rate of the control group was 240.51%, and the weight gain rate of the soft pellet feed group was 289.72%, which was significantly higher than that of the control group, showing good growth performance.

Abstract

The invention provides soft pellet aquatic feed which is convenient to use and can replace alive small trash fishes. The soft pellet aquatic feed is mainly prepared from fishmeal, seaweed meal, beer yeast powder, fermented soybean meal, poly-phycocolloid, lysine, methionine, arginine, monopotassium phosphate, choline chloride and the like; the moisture content is more than or equal to 20% and less than or equal to 40%. The soft pellet aquatic feed can be produced in a large scale in a factory-like manner; meanwhile, the soft pellet aquatic feed can be preserved at a room temperature for more than 30 days and does not go bad.

Description

technical field [0001] The invention relates to a soft granular aquatic feed which is easy to use and can be mass-produced in factories, and belongs to the field of feed. Background technique [0002] At present, the known industrialized aquatic feeds generally only have dry feeds with a content of less than 12% such as hard pellet feeds, extruded feeds, and powdered feeds. There is no industrial production of soft pellet aquatic product feeds with a water content greater than 20%, although some Farmers use some dry powder raw materials such as small miscellaneous fish and animal offal, and then extrude soft pellet feed through stirring. Because it cannot be kept fresh and stored, it is limited to fresh feeding. Although artificial dry feed has advantages such as storage resistance, it also has many disadvantages. [0003] More importantly, during the production process of feed, high temperature and high pressure links cannot be avoided, and high temperature and high pressu...
