Problems solved by technology

In addition, the relatively high addition of calcium dihydrogen phosphate in the feed will also cause eutrophication of the water body and destroy the ecological balance.
[0005] However, there is a large amount of phytate phosphorus in plant feed materials, especially grain by-products. Since the digestive tract of aquatic animals does not contain phytase, the phytate phosphorus cannot be effectively digested, absorbed and utilized by animals, and it is discharged into water bodies. A kind of waste can also cause eutrophication of water body and cause water pollution

Embodiment 1

[0035] The composition of raw materials of the 100kg compound feed prepared by the present invention is: fish meal 38kg, soybean meal 10kg, cotton meal 6kg, rapeseed meal 9kg, subflour 11kg, tapioca alpha starch 6.74kg, squid paste 4kg, shrimp shell powder 4kg, fish oil 3kg, phospholipid 1kg , food attractant 0.5kg, ecdysin 0.2kg, antioxidant 0.01kg, fungicide 0.01kg, crab premix 5kg, calcium dihydrogen phosphate 1.5kg, neutral phytase addition 0.04kg (enzyme activity The total amount is 100000U).

[0036] The enzyme activity content of the neutral phytase used in this example is 2500U / g, that is, the total amount of enzyme activity of 0.04kg neutral phytase is 100000U.

[0037] The enzyme activity is defined as: release 1 μmol of inorganic phosphorus per minute from a sodium phytate solution with a concentration of 5.0 mmol / L at a temperature of 30°C and a pH value of 6.00, which is a unit of phytase activity.

Embodiment 2

[0047] The composition of the raw materials of the 100kg compound feed prepared by the present invention is as follows: 36kg of fish meal, 12kg of soybean meal, 6kg of cotton meal, 10kg of rapeseed meal, 11kg of subflour, 6.78kg of cassava alpha starch, 3kg of squid paste, 4kg of shrimp shell powder, 3kg of fish oil, phospholipid 1kg, food attractant 0.5kg, ecdysin 0.2kg, antioxidant 0.01kg, fungicide 0.01kg, crab premix 5kg, calcium dihydrogen phosphate 1.5kg, liquid neutral phytase 60mL.

[0048] The enzyme activity content of the liquid neutral phytase used in this example is 2500U / g, that is, the total enzyme activity of 60mL neutral phytase is 150000U.

[0049] Above-mentioned formula is processed as follows:

[0050] 1. Fishmeal, soybean meal, cotton meal, rapeseed meal, sub-meal powder, and shrimp shell powder are pulverized for the second time, and all of them can pass through a 40-mesh sieve, and the content on a 60-mesh sieve is less than 10%;

[0051] 2. Use a blen...

Abstract

The invention relates to a juvenile horse crab feed formula and a processing method thereof. The feed formula includes fish meal, soybean meal, cottonseed meal, rapeseed meal, wheat middling, cassava alpha starch, squid extract, shrimp shell meal, fish oil, phospholipid, feed attractant, ecdysone, antioxidant, mildew preventive, premix, monocalcium phosphate and neutral phytase. The method for preparing the compound feed is as follows: the materials are weighed according to formula proportion, ground, uniformly mixed in a mixer and produced into pellets, the diameter of the pellet is 3mm, thelength of the pellet is larger than or equal to 3cm, and the pellets are dehydrated and cooled by cold wind. The method for adding the neutral phytase depends on the processing temperature, and the neutral phytase can be directly put into the materials before pelletization, or can be sprayed on the pellet feed after pelletization. The nutrition of the feed is rich, and palatability is good; the addition of the phytase increases the utilization rate of phytate phosphorus, the dosage of the monocalcium phosphate is reduced, consequently, the cost is reduced, the discharge of phosphorus in wateris reduced, environment pollution is reduced, and ecological equilibrium is protected.

Description

technical field [0001] The invention relates to a feed formula for aquatic animals and a processing method thereof, in particular to a feed formula for juvenile Portunus trituberculatus and a processing method for the formula feed. Background technique [0002] Portunus trituberculatus is referred to as swimming crab, commonly known as basket crab or gun crab. It is very popular at home and abroad. Most of the portunus trituberculatus caught in our country every year are used for export to earn foreign exchange, and only a small part is supplied to the domestic market. Due to overfishing, its natural resources are increasingly scarce, and the annual catch is even more difficult to meet domestic and foreign demand. Market demand, in order to make up for the shortage of natural resources and meet market demand, research on artificial breeding of Portunus trituberculatus has been carried out at home and abroad. Large-scale artificial breeding also brings higher requirements fo...
