Embodiment 1

[0016] The ingredients of artificial compound powder feed are: 42% defatted fish meal; 8% fermented soybean meal; 2% active yeast; 8% krill meal; 12% soybean meal; 3% alginate; 1% calcium chloride; 3% calcium dihydrogen phosphate ; a-starch 20%; beta-1,3-glucan 2%; citric acid 2%; lactic acid bacteria 0.5%; vitamin and mineral premix 3%.

[0017] The ratio is a mass percentage. 70% minced meat and 30% (mass percentage) of artificial powdered feed were mixed evenly, and then put into a pellet feed extruder to make a soft pellet feed with a diameter of 0.9 cm and a length of 2.2 cm. After drying in the shade for 4 hours, store in the refrigerator.

[0018] The feed is calculated by weight percentage, and 30% of the powdered feed is mixed with 70% of the fresh minced fish meat evenly.

[0019] Among them, the ingredients of artificial compound powder feed are: 42% defatted fish meal; 8% fermented soybean meal; 2% active yeast; 8% krill meal; 12% soybean meal; 3% alginate; 1% ca...

Embodiment 2

[0024] The ingredients of artificial compound powder feed are: defatted fish meal 45%; fermented soybean meal 9%; active yeast 2.5%; krill meal 8.2%; soybean meal 10%; algin 2%; calcium chloride 0.8%; calcium dihydrogen phosphate 2.5% ; a-starch 14.7%; beta-1,3-glucan 1.5%; citric acid 1.5%; lactic acid bacteria 0.3%; vitamin and mineral premix 2%. The ratio is a mass percentage. 70% minced meat and 30% (mass percentage) of artificial powdered feed were mixed evenly, and then put into a pellet feed extruder to make a soft pellet feed with a diameter of 0.8 cm and a length of 2 cm. After drying in the shade for 3 hours, store in the refrigerator.

[0025] The feed is calculated by weight percentage, and 30% of the powdered feed is mixed with 70% of the fresh minced fish meat evenly.

[0026] The fermented soybean meal requires that the total number of lactic acid bacteria is greater than 5×10 9 , can be purchased according to the standard. The premix of vitamins and mineral...

Embodiment

[0030] The adult fish soft pellet feed is prepared according to the following method:

[0031] The ingredients of artificial compound powder feed are: 46% defatted fish meal; 7.5% fermented soybean meal; 2.3% active yeast; 8.6% krill meal; 11% soybean meal; 2.5% alginate; ; a-starch 13.2%; beta-1,3-glucan 1.5%; citric acid 1.5%; lactic acid bacteria 0.3%; vitamin and mineral premix 2%. The ratio is a mass percentage. 70% minced meat and 30% (mass percentage) of powdered feed were mixed evenly, and then put into a pellet feed extruder to make a soft pellet feed with a diameter of 1.0 cm and a length of 3 cm. After drying in the shade for 4 hours, store in the refrigerator.

[0032] The feed is calculated by weight percentage, and 30% of artificial powder feed is mixed with 70% of fresh minced fish meat evenly.

[0033] The fermented soybean meal requires that the total number of lactic acid bacteria is greater than 5×10 9 , can be purchased according to the standard. The p...

Abstract

The invention relates to an artificial feed, and particularly relates to an adult giant salamander feed and a preparation method thereof. The feed is prepared by uniformly mixing 20-50% of powdery feed and 50-80% of minced fresh fish in percentage by weight, wherein the powdery feed comprises the following components in percentage by weight: 30-60% of defatted fish meal, 2-10% of fermented soybean meal, 1-5% of active ferment, 2-10% of krill powder, 5-15% of soybean meal, 0.5-4% of sodium alginate, 0.2-3% of calcium chloride, 0.5-5% of monocalcium phosphate, 5-25% of alpha-starch, 0.1-3% of beta-1, 3-glucan, 0.1-2% of citric acid, 1-5% of premix of vitamins and mineral substances and 0.1-0.5% of lactic acid bacteria. According to the invention, a powdery compound feed and the fresh minced fish are mixed according to a certain proportion so as to prepare a soft-granule feed; the feed is rich in nutrition, is good in viscosity, contains partial biodiasmin, and well meets the requirements of the adult giant salamander on nutrition, palatability and water resistance of the feed.

Description

technical field [0001] The invention relates to an artificial feed, in particular to an adult giant salamander feed and a preparation method thereof. Background technique [0002] Giant salamander (Megalobatrachus davidianus) is a rare and rare wild animal unique to my country, which has high economic value, medicinal value and nutritional and health care functions. At present, artificial breeding of giant salamanders is mainly based on feeding fish pieces, supplemented by fresh and live small fish and shrimps. However, under the current situation, the bait is relatively simple, the nutrition is not balanced and the cost is high, which affects the growth performance and breeding efficiency of giant salamanders. Contents of the invention [0003] The object of the invention is to provide a soft granular feed for adult giant salamander and a preparation method thereof. [0004] To achieve the above object, the technical solution adopted in the present invention is: [000...
